Hi team, I got a query on Hyperledger Indy and Aries. I have worked with Indy for about 6 months. My question is that, every holder/user on the network is assigned a service endpoint which the user gets connected to. The service endpoint is a different port number for each user on the network. So would this architecture be scalable as we might be needing to assign identity to thousands, millions or billions of users at some later point of time. How Sovrin would be handling the IP address ranges to be assigned to the users/holders in future?

Another question... I see a lot of the same examples on the acme/alice/thrift samples... I read that PII is not to be stored in the ledger, but many examples show Alice's SSN... how are entities viewing Alice's SSN without having access to the ledger?

domwoe (Mon, 13 Jul 2020 08:24:30 GMT):
There's no API for that in indy-sdk. You can have a look at the implementation of the did:sov driver for the universal resolver. How the indy-sdk can be used to generate a DIDdoc. https://github.com/decentralized-identity/uni-resolver-driver-did-sov

The credential goes from the Issuer to the Holder, e.g. from the gov't (including SSN) to Alice. Later Alice presents proof of the claims in the credential (some or all, possibly combined with claims from other credentials) to a verifier (say, Acme). None of the data in the credential goes to the ledger. What goes to the ledger are metadata about the credentials (e.g. names of the claims - data elements) and cryptographic public keys needed in constructing the proof (by Alice) and to verify the proof (executed by Acme).

swcurran (Mon, 13 Jul 2020 23:04:22 GMT):
I know about three of the ledgers and have a guess on the fourth: - Domain is the identity transactions -- the DIDs (NYMs), Attributes of nyms, schema, credential definitions, revocation registries and revocation entries. That's the "data" of the ledger. - Config are the transactions that change the network. For example, to trigger updates to the software. I think (not certain) the authorization data is there as well. - Node lists the nodes (current and past) that are participating in the validation. - Fourth is optional (I believe) based on the configuration for a token that can be added to the network.

swcurran (Mon, 13 Jul 2020 23:13:47 GMT):
To see the transactions on an indy ledger, you can look at indyscan.io which has a ledger browser for each of the Sovrin networks (Main, Staging and Builder).

I understand that each one has a separate function, but it does complicate things. Like each ledger needs to have its own sync logic rather than having one ledger that has all the necessary logic. Are there documents/papers that describe the benefit of such scheme? The reason is that I am responsible for building a network for decentralized identity and need to understand the reasoning behind indy... I've played and delivered end-to-end solutions with Bitcoin, ethereum, hlf, and a few other ledgers. Indy is a bit new and still grasping the architecture.

Hello folks! I'm using Libindy from React-Native using the Java wrapper within Android (Indy 1.14.2). Upon trying to open a pool handle (openPoolLedger()), the app crashes with a signal 6 SIGABRT, with no other error messages. It crashes on the socket.connect() call, and since that uses zmq, that leads it to be my most suspected issue. I have enabled the internet and networking permissions for the app (as well as enabling cleartext messages in the manifest), and have ensured the call is being run in a separate thread from the main thread. I am open to any ideas anyone might have. Thanks!

Hi, I have a question about the Verkeys. When I use the Indy-CLI to create a DID based on a seed I get a short verkey (~VERKEY). The Full-Verkey on the ledger seems to be DID+VERKEY. But when I create a DID using Indy-SDK with the CreateAndStoreMyDidAsync method I get a DID and a FULLVERKEY. Now I would like to know how this looks like when using this DID based on the seed. If I want to use a DID created with the Indy-CLI later in an application that uses the Indy-SDK (or Aries) or vice versa to sign transactions for the ledger, this might not work, because the verkey created in the application does not match the verkey on the ledger.

tomislav (Tue, 14 Jul 2020 17:57:30 GMT):
A note on key abbreviation and DID relationship. The DID is simply the first 16 bytes of the verkey, represented in base58. The abbreviated key, is the other lefotver bytes with a ~ prefix, so you can easily construct the full verkey by concatenating the the DID and abbreviated verkey. When a user rotates their key for a DID and write that to the ledger, that key can no longer be represented in abbreviated form.

Thank you. I saw that after doing some searching. Looks like predicate support is limited as of now. Will suffice though.

Hi team I have a question about anoncreds 1.0 VS 2.0 Using tails, revoc entry contains only index number (matched prime number is not exposed) so revoked information can be hidden. But using merkle tree, as described in https://jira.hyperledger.org/browse/INDY-2365, (I understood like 0010000.. -> cred with index number 3 revoked) index number is the only information (there is no matched hidden factor like prime number in tails) so I think anyone who has merkle root can derive revoked information of credential. Is there any way to hide revoked information of cred with merkle tree(anoncreds2.0)?? thanks.

Hello, I am new to indy,when I run the how-to Tutorials，there is one error:from utils import get_pool_genesis_txn_path, PROTOCOL_VERSION ImportError: cannot import name 'get_pool_genesis_txn_path' from 'utils'，I have installed all dependencies and with a running indy pool,could anyone help me to figure out the problem. Thanks

berserkr (Tue, 21 Jul 2020 07:29:20 GMT):
did you run `pip install .` in the local dir?

berserkr (Tue, 21 Jul 2020 07:34:42 GMT):
My advice is to go ahead and install the pool as described in the indy-sdk example

berserkr (Tue, 21 Jul 2020 07:34:54 GMT):
then you run install inside of the wrapper of your choice

jameshiester (Thu, 23 Jul 2020 12:52:00 GMT):
Devs can correct me if I'm wrong, but I think it's because the SDK allows retrieving by seqNo, but not by schema_id. If you wanted to retrieve the schema given only the credential_def, there would be no efficient way to do so using only schema_id without having all the transaction history cached

Regularly a Timeout error is due to something with your IP addresses or networking configuration. Check your pool Genesis file first and then track it down from there.

Hi everyone... How can I dump the whole ledger transactions via de indy-cli?

I need it to validate the ledger transactions after operations for testing

MrWoody (Thu, 30 Jul 2020 22:33:04 GMT):
and document the whole ledger transactions

MrWoody (Thu, 30 Jul 2020 22:33:10 GMT):
for now, I can visually do it with Greenlight

MrWoody (Thu, 30 Jul 2020 22:33:20 GMT):
but if indy-cli could do it, it would help

andrew.whitehead (Thu, 30 Jul 2020 22:52:00 GMT):
You could use the indy-vdr-proxy tool at https://github.com/hyperledger/indy-vdr

MrWoody (Thu, 30 Jul 2020 23:03:09 GMT):
Oh, another tool... ok, I'll take a look at it. No way to do it via simple indy-cli right?

andrew.whitehead (Thu, 30 Jul 2020 23:04:05 GMT):
Not sure if it has a method to fetch transactions

Ok.. I'll try VDR in the meantime. Thanks

WadeBarnes (Fri, 31 Jul 2020 13:17:04 GMT):
The `indy-cli` does not support dumping the transactions.

andrew.whitehead (Wed, 05 Aug 2020 15:51:41 GMT):
It's not an indy-node feature, we just perform a GET_TXN request against the individual nodes instead of VALIDATOR_INFO

jameshiester (Wed, 05 Aug 2020 15:55:10 GMT):
ah ok, and then an error response is equivalent to a node being offline? for vdr, are there plans to add a status endpoint that shows nodes online/offline? @swcurran alluded to as much

swcurran (Wed, 05 Aug 2020 15:58:19 GMT):
Not in indy-vdr, but look at indy-node-mointor, which is based on indy-vdr

swcurran (Wed, 05 Aug 2020 15:58:32 GMT):
https://github.com/bcgov/indy-node-monitor

jameshiester (Wed, 05 Aug 2020 16:02:45 GMT):
ahh ok. Personally I would say it's a little misleading that the '/' endpoint in vdr returns all nodes regardless of whether they're online or not.

andrew.whitehead (Wed, 05 Aug 2020 16:05:25 GMT):
That's meant as more of a 'pool refresh status' page to see if it has the most recent pool transactions

Easiest way to run a local network is using von-network, which also gives you guidance on how you can run your own on bare-metal (which is not very useful IMHO - depends on your goals). https://github.com/bcgov/von-network BC Gov operates some open instances of von-network -- listed here (BCovrin links - https://vonx.io/clickythings/) Closer to production are the three Sovrin networks - MainNet, Staging and BuilderNet -- https://sovrin.org

I think the Plenum protocol is what you're looking for: https://github.com/hyperledger/indy-plenum/wiki#:~:text=The%20Plenum%20protocol,Ben%20Mokhtar%2C%20and%20Vivien%20Qu%C3%A9ma.

esplinr (Thu, 06 Aug 2020 23:05:57 GMT):
You are correct that an Indy attack would have to take over 3f +1 machines to produce the BSL signature necessary to hijack the ledger history. This is because it is a permissioned ledger, versus a permissionless ledger like the Blockchain.

I'm looking to standup an Indy test network. I realize the Indy readthedocs site doesn't have current info for SDK ( even Python scripts ) on the sample scripts. Can someone point me to better documentation resources? Is there a good end-to-end tutorial recommended that shows the Indy setup, creating a steward, trust anchor and issuing identities and credentials for individuals? Thanks !

swcurran (Sat, 08 Aug 2020 20:12:39 GMT):
A good place to start to get a local network running is here: https://github.com/bcgov/von-network It spins up a 4-node network for you, with a web interface that lets you create DIDs that can be used to create other objects.

swcurran (Sat, 08 Aug 2020 20:15:35 GMT):
Unless you are planning to be an Indy network operator (which seems unlikely) manually setup an Indy network is not something you really need to know. Interacting with a network is what's interesting --- either in building Agents (e.g. developing at the Aries level), or building agents for specific business uses -- issuers, holders and verifiers.

swcurran (Sat, 08 Aug 2020 21:29:33 GMT):
Indy devs ( @esplinr ) -- How flexible are the configuration rules for writing transactions to the ledger -- e.g. rules like when an endorser/trustee/steward needs to sign a transaction to write (for example) a DID? Notably, can the rules for writing a RevReg reference the owner of the CredDef to which the RevReg is to be written? Likewise, can a RevEntry be constrained to only be written by the owner of the RevReg to which the RevEntry is associated?

esplinr (Sun, 09 Aug 2020 06:27:12 GMT):
The documentation is here: https://github.com/hyperledger/indy-node/blob/master/docs/source/transactions.md#auth_rule

esplinr (Sun, 09 Aug 2020 06:27:56 GMT):
It was intended to be flexible, but we didn't specifically address the Revocation Registry use case.

in a proof, how do the signatures show that the holder was issued the credential if the holder/creator of the proof is using a different did than the one to which the credential was issued (as in the case of two pairwise did connections)?

In Indy anoncreds, the holder provides the issuer a blinded link secret that is inserted into the credential before it is issued. To prove the credential, the holder must prove (in zero knowledge) that they possess the link secret to unblind the the blinded link secret. That proves that the entity that constructed the proof was the one to which the credential was issued. When there are multiple credentials sourced into a single proof, all must use the same link secret. The pairwise DIDs are only for secure communication. They are not used as part of the credential exchange process.

jameshiester (Mon, 10 Aug 2020 13:35:49 GMT):
also just to make sure, rotating keys would not affect that ability to unblind correct?

swcurran (Mon, 10 Aug 2020 13:39:16 GMT):
In anoncreds, you don't change the link secret --- it's held in the wallet and never exposed. Rotating keys of the DIDs used for DIDComm has no impact on the link secret or the unblinding process.

lynn.bendixsen (Mon, 10 Aug 2020 18:21:47 GMT):
In looking at the auth rules, and reviewing the ledger, I am pretty sure that a rev_reg_def is created at the same time as a credential definition by the same owner and is directly associated with that cred_def. The auth_rules already indicate that any rev_reg "add"s or "edit"s must be done by the owner. `"need_to_be_owner": true` So, Yes, the RevReg entries's can be and are constrained to only be written to, by the owner of the cred_def/rev_reg_def.

WadeBarnes (Mon, 10 Aug 2020 19:23:09 GMT):
The rules appear to be different for each ledger.

WadeBarnes (Mon, 10 Aug 2020 19:25:51 GMT):
For MainNet it looks like you need a privileged DID in order to *ADD* a *REVOC_REG_DEF* or *REVOC_REG_ENTRY*

WadeBarnes (Mon, 10 Aug 2020 19:27:18 GMT):
What is the `owner` context for *REVOC_REG_DEF* txns? I assume it would be the `owner` of the *CRED_DEF*. Is that correct?

WadeBarnes (Mon, 10 Aug 2020 19:30:28 GMT):
My thoughts: - The owner of a *CRED_DEF* should be able to freely ADD/EDIT *REVOC_REG_DEF* txns for their *CRED_DEF*(s), and freely ADD/EDIT *REVOC_REG_ENTRY* txns for their owned *REVOC_REG_DEF*(s).

WadeBarnes (Mon, 10 Aug 2020 19:30:28 GMT):
My thoughts: - The owner of a *CRED_DEF* should be able to freely ADD/EDIT *REVOC_REG_DEF* txns for their *CRED_DEF*(s), and freely ADD/EDIT *REVOC_REG_ENTRY* txns for their owned *REVOC_REG_DEF*(s). - You should not need a privileged DID in order to do this. - I would expect there would be some fee associated to writing these txns, similar to the way there is a fee for writing attributes.

WadeBarnes (Mon, 10 Aug 2020 19:51:22 GMT):
The [Who Is Owner](https://github.com/hyperledger/indy-node/blob/master/docs/source/auth_rules.md#who-is-owner) section of the *Default AUTH_MAP Rules* document does not list the owner in the context of the *REVOC_REG_DEF*. How do we confirm the owner in this context?

lynn.bendixsen (Mon, 10 Aug 2020 19:51:40 GMT):
I can help explain the rules part of this. The rules I was referencing in my previous response were for the MainNet and they are mostly the same for the other networks. The main differences are that on MainNet only an endorser can ADD a credDef/RegDef. This means that they are also the only ones that can ADD/EDIT entries or other related actions. A Transaction Author must find an Endorser to sign these actions for them. This was done because Endorser was the role assigned to do all of the credential issuance type txn's while the ledger remains permissioned. Allof those txn's are fee based and are charged to the Endorser monthly. I am almost certain that the owner context for RegDef txns is the owner of the RegDef. Since the reg def is created in conjunction with a credDef, the owner of the RegDef is the same as the associated credDef. This appears to be a 1:1 relationship and I am uncertain if you can make multiple RegDef's per CredDef.

lynn.bendixsen (Mon, 10 Aug 2020 19:54:15 GMT):
You can confirm "owner" type issues by trying things out on the BuilderNet, but I am pretty certain that "owner" always refers to the original signer of the TXN.

WadeBarnes (Mon, 10 Aug 2020 19:54:33 GMT):
As I understand it you can have more than one *REVOC_REG_DEF* for a given *CRED_DEF* since the *REVOC_REG_DEF* only has limited use.

WadeBarnes (Mon, 10 Aug 2020 19:55:25 GMT):
This is also the basis of my thoughts.

WadeBarnes (Mon, 10 Aug 2020 19:55:25 GMT):
This is also the basis of my thoughts of the *CRED_DEF* owner being able to freely write a new *REVOC_REG_DEF* without the need to have the txn signed by a second or third party.

lynn.bendixsen (Mon, 10 Aug 2020 19:56:57 GMT):
That muddies the waters a bit then, but creating a RegDef for a CredDef that you do not have ownership of makes no sense.

WadeBarnes (Mon, 10 Aug 2020 19:57:33 GMT):
Agreed. That's why I'd like to confirm the `owner` context.

WadeBarnes (Mon, 10 Aug 2020 19:57:33 GMT):
Agreed. That's why I'd like to confirm the `owner` context for the *REVOC_REG_DEF*

WadeBarnes (Mon, 10 Aug 2020 19:57:33 GMT):
Agreed. That's why I'd like to confirm the `owner` context for the *REVOC_REG_DEF*. To confirm `"need_to_be_owner": true` on a *REVOC_REG_DEF* means you need to be the owner of the associated *CRED_DEF*.

lynn.bendixsen (Mon, 10 Aug 2020 19:59:42 GMT):
I think I was wrong when I said "I am pretty certain that "owner" always refers to the original signer of the TXN." I believe that the "owner" is actually the txn author, or writer of the txn (not the signer or endorser, unless the endorser is also the author).

WadeBarnes (Mon, 10 Aug 2020 20:02:33 GMT):
If the above is true, `"need_to_be_owner": true` on a *REVOC_REG_DEF* means you need to be the owner of the associated *CRED_DEF*, then we can adjust the rules on ADD/EDIT for *REVOC_REG_DEF* and *REVOC_REG_ENTRY* so they make sense for the real world use cases we're working though right now.

lynn.bendixsen (Mon, 10 Aug 2020 20:03:29 GMT):
Sorry, but I don't know for sure on the RegDef "ownership" question. In all of the ownership cases that I have tested "owner" means writer of the txn, not "writer of some other assoctiated txn"

WadeBarnes (Mon, 10 Aug 2020 20:04:59 GMT):
Example: *REVOC_REG_ENTRY*, owner means the owner of the DID used to create the corresponding *REVOC_REG_DEF*.

WadeBarnes (Mon, 10 Aug 2020 20:04:59 GMT):
Example: *REVOC_REG_ENTRY* txns, owner means the owner of the DID used to create the corresponding *REVOC_REG_DEF*.

lynn.bendixsen (Mon, 10 Aug 2020 20:07:25 GMT):
You could test on builderNet by adding a new credDef as an Endorser, then attempting to add a new RegDef for it as a Trustee. Trustees can create RegDef's on BuilderNet but "owner:true" is set appropriately...

lynn.bendixsen (Mon, 10 Aug 2020 20:09:46 GMT):
I am not sure yet why we would need to change the rules if what you say is true. Perhaps a zoom chat will help me understand what needs changed?

I think I found the code, and it does not look like the validation for the *REVOC_REG_DEF* (https://github.com/hyperledger/indy-node/blob/master/indy_node/server/request_handlers/domain_req_handlers/revoc_reg_def_handler.py#L43) validates an owner (for the *CRED_DEF*) like the validation for the *REVOC_REG_ENTRY* (https://github.com/hyperledger/indy-node/blob/master/indy_node/server/request_handlers/domain_req_handlers/revoc_reg_entry_handler.py#L31) does (for the *REVOC_REG_DEF*).

Sorry Wade, my bad I've mixed the Von network with another sample. It started, however I have an "Error initializing pool ledger" in the interface (as a result of the "status" call), even if it seems that all the nodes seems to be running well

WadeBarnes (Tue, 11 Aug 2020 14:35:06 GMT):
Try resetting things: `./manage down` wait for command to complete `./manage start`

WadeBarnes (Tue, 11 Aug 2020 14:36:00 GMT):
That error is typically a startup timing issue with the ledger browser connecting to the nodes.

WadeBarnes (Tue, 11 Aug 2020 14:37:56 GMT):
The startup timing can be adjusted here; https://github.com/bcgov/von-network/blob/master/docker-compose.yml#L25

In talking with the Indy team some time ago I was told that "the sweet point" for the size of a production Indy ledger was 25 nodes --- large enough to be resilient (allowing up to 8 node failures), but small enough to have reasonable consensus performance. I was asked about whether there is documentation about the testing done to come up with that metric and I don't have any. @esplinr -- do you know of such information? Anyone else? Thanks

esplinr (Mon, 17 Aug 2020 14:48:09 GMT):

Hello, Does each validator holds a separate node in Indy?

lynn.bendixsen (Wed, 19 Aug 2020 19:51:31 GMT):
Yes, if I understand your question correctly. In Indy we regularly use the terms "Validator" and "Node" to mean the same thing.

avi23 (Wed, 19 Aug 2020 19:54:16 GMT):
okay, what i mean to ask is how many minimum and maximum validators can be there in any indy network? and does each validator need to assign a separate node in system?

lynn.bendixsen (Wed, 19 Aug 2020 19:59:02 GMT):
Minimum is 4, maximum is unknown, but we recommend maxing out at 25 validator nodes because after that there is a significant performance reduction. Yes, each Validator is a single node in our system (a separate server is required for each Validator Node in Sovrin's networks, for example)

avi23 (Wed, 19 Aug 2020 20:00:22 GMT):
thanks @lynn.bendixsen for the reply..

avi23 (Wed, 19 Aug 2020 20:02:20 GMT):
@lynn.bendixsen could you also please confirm that is it mandatory that Each holder and Issuer also holds a separate node?

avi23 (Wed, 19 Aug 2020 20:03:09 GMT):
i mean who all parties in any Indy network should be assign a node?

lynn.bendixsen (Wed, 19 Aug 2020 20:11:56 GMT):
I am not sure what you mean by 'holder' and 'issuer' in this context. Perhaps you are using the terms differently? In "Indy/Aries" terminology an "Issuer" and a "Holder" are terms used in delivering and having credentials, and there are an indeterminately large number of those that can exist on each Indy Network, regardless of how many nodes are in the network. In the Sovrin Indy Networks, there are Stewards who have volunteered to run the nodes (based on their governance documents). Each Steward is only allowed to run one Node. In a theoretical generic Indy network, this boils down to "each STEWARD DID on the ledger can only instantiate one Indy node".

avi23 (Wed, 19 Aug 2020 20:16:26 GMT):
thanks for the insights @lynn.bendixsen , so if i ask in general that how many nodes other than validators as you mentioned above is required to form a indy network? i mean i am just curios to know in perspective of a network setup

lynn.bendixsen (Wed, 19 Aug 2020 20:18:49 GMT):
None, there are currently no Indy nodes that are not validator nodes in an Indy Network.

TimoGlastra (Wed, 19 Aug 2020 20:41:46 GMT):
Hi, could anyone tell me the difference between full length verkeys and abbreviated verkeys? Why would I want to use one over the other? Looking at the indy code whether an abbreviated verkey is used is dependant on the `cid` parameter. What does `cid` mean? I tried to find it somewhere in the docs, code, etc.. but no luck.

andrew.whitehead (Wed, 19 Aug 2020 21:25:56 GMT):
The verkey is 32 bytes, and by default in Indy the DID is chosen as the first 16 bytes of that key, before base58 encoding. The abbreviated verkey just replaces the first 16 bytes with ~ when it matches the DID.

lynn.bendixsen (Wed, 19 Aug 2020 22:03:06 GMT):
I am not an expert, but because I was curious... Everything I see when googling "cid hyperledger indy" seems to indicate the following: 1. cid means cryptonym ID 2. cid is deprecated 3. the cid parameter you refer to indicates the length of the DID/CID and not the length of the verkey. (or at least it used to, https://docs.rs/crate/indy/0.1.1-70/source/src/api/signus.rs)

TimoGlastra (Wed, 19 Aug 2020 22:34:40 GMT):
Thanks @andrew.whitehead and @lynn.bendixsen . That makes sense. I now see the `cid` indeed indicates the length of the did, not the verkey.

The expected model is that the there would be a revocation of the current credential and a reissue of a new one.

swcurran (Wed, 19 Aug 2020 23:28:49 GMT):
Just to be very clear in this conversation -- if your are talking about a issuer and verifier in the Verifiable Credentials sense of the terms, neither of them needs run a node on the Indy Network. An issuer needs to be able to write certain transactions to the ledger and so needs permission to do that, and a verifier just needs to read from the network and that is public.

swcurran (Wed, 19 Aug 2020 23:30:39 GMT):
There is no "issuer" in the context of an Indy network node and the term "validator" is used to mean that the nodes validate what gets written to the ledger. All of that is well below the layer dealing with verifiable credentials.

Hello again! I was wondering how and where is the wallet object stored? Locally? The walkthrough and examples make it look like a serializable object. So my guess would be to store it in a cryptographically secure file in the user's machine, or file storage.

swcurran (Thu, 20 Aug 2020 15:33:02 GMT):
Yes. It's stored in a database which can be local or on another server. The database is pluggable and there are SQLite and Postgres plugins available.

Hi all, I am currently working on a project but I am confused in some concepts. First, where is the wallet that stores the credentials saved? Is it saved on a blockchain or just a local database? Secondly, I still don't get how the verifier entity verifies the correctness of the presented values? From what I understood, the personal data of the student or the holder of a transcript are not saved on the ledger, so what does the verifier compare against the ledger if the data is not there? I would appreciate your help, thank you in advance.

jameshiester (Mon, 24 Aug 2020 16:11:18 GMT):
The wallet, including credentials, are stored in database. This can either be the default local database (I believe it's rocksDB or sqlite), or use a storage plugin such as the postgresql plugin, which would store the wallet in any postgres database (which can be either local or in the cloud). With respect to verifying the "correctness" of the presented values, it is more correct to say that the verifier is verifying the source of the presented values, which is the authority that issued the credential. The issuer authority has a public verkey that is published to the ledger, along with a key associated with the credential definition. These keys are used to "sign" the credential. When generating this signature, the private keys associated with the authority issuer and credential definition are used, as well as the actual value of the credential. This ensures that only the issuer authority can generate a valid signature, and the properties of the credential cannot be modified without invalidating the signature. Therefore, by validating the signature, the verifier is confirming the source and veracity of the credential data.

jameshiester (Mon, 24 Aug 2020 16:13:13 GMT):
Note: I'm not 100% certain that's accurate about the private key of the credential definition, but I am confident about the general gist of the signature and it's use

MarinaELias (Mon, 24 Aug 2020 16:19:26 GMT):
Thank you so much for your reply! I understand now, but my last question is from where does the verifier get the signature on the credential, is it send with the data that is presented to the verifier from the chosen credential?

jameshiester (Mon, 24 Aug 2020 16:22:32 GMT):
yes, credentials are not send directly from the holder to the verifier, but rather as part of a presentation that the holder creates. This presentation includes the values (if the holder chooses to reveal them), and the signatures. This allows the holder to use multiple credentials in a single proof, as well as the ability to use zero-knowledge proofs (e.g. proving they are over 18 without including their actual birthdate in the proof).

Okay so in the end what proves the correctness of the credential is its digital signature. So what is the role of the blockchain besides storing the public keys of each entity, as the public keys could be stored anywhere else without the need for a blockchain. What am I missing?

jameshiester (Mon, 24 Aug 2020 17:01:35 GMT):
The blockchain acts as a decentralized authority for the keys, schemas, and revocation registries. While alternative systems are also feasible, the ledger provides an excellent way to achieve consensus around what format those keys and schemas should be published in, and a consistent and fault tolerant way of reading them. Additionally, the blockchain creates an immutable record, so it is easy to audit the entire trail of a schema or key back to who created it, and even who onboarded that identity and all the ancestor identities going back to the original genesis transaction. In short, it's a good way of allowing peer-to-peer credential sharing, while still creating an anchor of trust.

MarinaELias (Mon, 24 Aug 2020 18:51:18 GMT):
Okay, thank you so much for your help!

Hi again, I am sorry but there is something I still don't get, how does the Proof verify that the claims were issued to the presenter? What makes it impossible for someone to steal the student's identity?

jameshiester (Tue, 25 Aug 2020 12:19:06 GMT):
The answer lies in a secret passwed between the student and original issuer. The holder (student) provides the issuer a blinded link secret that is inserted into the credential before it is issued. To prove the credential, the holder must prove (in zero knowledge) that they possess the link secret to unblind the the blinded link secret. That proves that the entity that constructed the proof was the one to which the credential was issued. When there are multiple credentials sourced into a single proof, all must use the same link secret. That being said, no digital system is 100% effective in preventing identity theft. The secret is still stored in the users wallet, so if an attacker is able to get access to the wallet and decrypt it, they would be able to steal the student's identity. This is why wallets need to be protected with strong authentication, which very likely includes biometrics

lynn.bendixsen (Tue, 25 Aug 2020 13:21:49 GMT):
I don't know, sorry.

swcurran (Tue, 25 Aug 2020 14:33:40 GMT):
Indy does not use ZK-SNARK. I believe that Ursa has some support, but that Indy does not use them. Better asked on the Ursa channel.

thearhaam (Wed, 26 Aug 2020 04:48:46 GMT):
Hey :D so I was going through this repo: https://github.com/cloudcompass/ToIPLabs/tree/master/src/indy-material/nodejs the README mentions "This folder contains a demonstration of basic Hyperledger Indy and Aries Agents, which are built on the Ursa project." However the code is the same as the old indy alice demo. Is there another repo that I can look into instead?

swcurran (Wed, 26 Aug 2020 13:41:02 GMT):
The ACA-Py contains a far more advanced version that continues to evolve. Check it out - https://github.com/hyperledger/aries-cloudagent-python

thearhaam (Wed, 26 Aug 2020 17:37:47 GMT):
@swcurran Thank you, I've gone through the ACA-Py demo already. Currently I'm exploring Indy & Aries but will be looking into Ursa as well so wanted to know if there was an example or demo with Indy, Aries and Ursa all working together.

swcurran (Wed, 26 Aug 2020 17:51:27 GMT):
Indy is dependent on Ursa (includes Ursa components in the build). ACA-Py's support for Indy by embedding the Indy SDK. That's how Ursa gets into Indy and Aries.

swcurran (Wed, 26 Aug 2020 17:51:48 GMT):
So whenever you use ACA-Py, you are using Ursa.

I want to make sure the Indy community is aware of this conversation happening in the W3C, in which it has been proposed to eliminate serviceEndpoint from the DID core spec. This would be disruptive to DIDComm. It appears that the proposal has been rejected (DIDComm is safe), but there are still some voices claiming that serviceEndpoint is useless nonsense. You might want to read the ticket or weigh in. HEre's a link: https://github.com/w3c/did-core/issues/382#issuecomment-683325040

pfeairheller (Tue, 08 Sep 2020 12:36:01 GMT):
For now there is no convention used for routing keys in an ATTRIB. We have the same concern and have settled on using 'routingkeys'. However, out of the Indy Interop-athon the decision was made to use an ATTRIB transaction to store full DIDDocs for DIDs. That work will be ongoing over the next couple of months I imagine. More information can be found here: https://wiki.hyperledger.org/display/II/Agenda. In the meantime, if you are thinking of using a custom ATTRIB for the routing keys it might make sense to just go ahead and store the entire DIDDoc in a custom ATTRIB and prepare yourself for the future changes.

Yes for diversity it is actually best if different nodes are in different clouds. Each node has a copy of the ledger that it uses to maintain consensus, but there is just one "ledger" per network. "How can we achieve the same?"

Each node has a public IP address and port that it communicates on for syncing.

danielhardman (Fri, 11 Sep 2020 18:10:00 GMT):
I am concerned about the ramifications for DIDComm of this DID core issue: https://github.com/w3c/did-core/issues/386 Joe A suggests that our (DIDComm designers) interpretation of the DID spec with regard to key rotation has no basis in the spec language. He may or may not be right, but I’m pretty confident that neither does the other interpretation he points out. I consider that other interpretation, where you can’t look up any DID state except the current one, to be totally unacceptable, to the point where I think we would have to abandon support for DIDs if key rotation is not supported. This is a BIG deal. Please be proactive about reading this ticket, commenting, and mustering support for our interpretation among like-minded community members.

Hello everyone, i try to understand the communication between the client and the node and found the different types of requests (https://hyperledger-indy.readthedocs.io/projects/node/en/latest/requests.html), but what underlying protocol (http, grpc, etc.) and endpoint is used?

swcurran (Mon, 14 Sep 2020 13:44:34 GMT):
It uses ZMQ, AFAIK. Devs can check me on that, but pretty sure :-)

Hey folks --- on the Indy Contributors call this coming Tuesday (September 15, 8AM Pacific, 5PM CET), we're going to be follow up on the first two actions needed out of the Indy Interop-athon -- CI/CD migration to GitHub Actions and the did:indy DID Method spec. We'll also review the outputs from the Indy Interop-athon as we turn talk into action. Please join us on the Contributors call this Tuesday -- https://wiki.hyperledger.org/display/indy/2020-09-15+Indy+Contributors+Call -- Zoom: https://zoom.us/j/244779296

Lucampelli (Tue, 15 Sep 2020 17:54:28 GMT):
Hello! I have a doubt about schema and credential definitions in the walkthroughs. I'm creating my own example to learn about the different flows. Is schema definition and cred_def issuance only allowed by the stewart trust anchor? I've sent requests for "TRUST ANCHOR" verinyms by the stewart, but these did's return unauthorized when sending schema definitions... am I doing something wrong?

swcurran (Tue, 15 Sep 2020 18:11:13 GMT):
No. Indy has a flexible authorization system for writes to the ledger. It's configurable, and in the Sovrin system (for example), there are 6 explicit roles: - readers -- anyone - author -- anyone with a DID on the ledger - network monitor -- has a DID and can query nodes to get detailed status about them - endorser -- has a DID and is permitted to sign transactions from authors and endorsers (including themselves) such that they can be written to the ledger. The endorser pays for all transactions that they sign and are written. - steward -- can operate a node on the ledger and contribute to validation - trustee -- can do what an endorser can do and can sign transactions to write endorser DIDs. So the TRUST ANCHOR is an Endorser on Sovrin, and so can sign and write it's on transactions, but a "normal" DID, cannot. In the sandbox environment, there is a TRUSTEE that you can create the DID for -- the seed for the DID is available for all.

Lucampelli (Tue, 15 Sep 2020 18:20:44 GMT):
Also, the indy_node pool from /docker/pool_start.sh is giving an error called CommonInvalidState

swcurran (Tue, 15 Sep 2020 18:21:02 GMT):
FYI - this Thursday (6AM Pacific / 3PM CET) we'll be holding an Indy Node / Indy Plenum release planning meeting for the next release of the ledger part of Indy. This is a great opportunity for anyone wanting to get involved in Indy development to pick up some tasks to contribute with support from existing contributors. We'll also be using this release to migrate the indy-node release process to GitHub Actions. Please join us on the normal Indy Contributors call Zoom -- https://zoom.us/j/244779296 See you there!

swcurran (Tue, 15 Sep 2020 18:21:58 GMT):
Regards your first question - No - nothing wrong. Indy has a flexible authorization system for writes to the ledger. It's configurable, and in the Sovrin system (for example), there are 6 explicit roles: - readers -- anyone - author -- anyone with a DID on the ledger - network monitor -- has a DID and can query nodes to get detailed status about them - endorser -- has a DID and is permitted to sign transactions from authors and endorsers (including themselves) such that they can be written to the ledger.

Lucampelli (Tue, 15 Sep 2020 18:24:12 GMT):
So even if stewart sends verinyms for an user for example, if the role is TRUST_ANCHOR the user can't create schemas, nor sign it's transactions, but if it's a TRUSTEE, it can?

Lucampelli (Tue, 15 Sep 2020 18:36:42 GMT):
Ok... so for some context, my code creates the stewart's wallet, then creates a regulatory agent, RA. Creates it's wallet, and stewart (maybe the gov) sends a verynim to the ledger appointing RA as Trust_anchor. RA then creates a schema (that's working) and now wants to create a cred_def based on it's schema, but i'm getting indy.error.CommonInvalidStructure.

Hello Folks, @swcurran can anyone please put some sight on how the master secret works in Indy to obtain the user anonymity? how can we hide user details like email , name etc using master secret key while presenting it for verification to verifier?

Lucampelli (Wed, 16 Sep 2020 14:05:36 GMT):
Ok.. solved one issue. The cred_def problem happened because i used the id instead of the json... didn't notice it. Now this is the problem: {'identifier': '5mhbTjB662MT599k6dpB4P', 'op': 'REQNACK', 'reason': "client request invalid: InvalidClientRequest('validation error " '[ClientClaimDefSubmitOperation]: cannot be smaller than 1 ' "(ref=0)',)", 'reqId': 1600265018440896430} i'm using only the "user" credentials, like did and wallet, not the stewart, since i made the "user" a trust_anchor... any leads?

swcurran (Wed, 16 Sep 2020 14:08:46 GMT):
It's crypto magic, but here is a quick summary. At issue time, the holder uses their link secret to create a piece of "blinded" data that they give to the issuer, who in turn puts it in the credential. At proving time, the holder uses their link secret to "unblind" that data. That proves to the verifier that the holder has the link secret that was used to blind the data that went into the credential. Further, that unblinded data is given to the verifier such that it is different in every proof, and does not create a unique identifier for the credential (Privacy preserving). That's at a high level -- you would have to go to the crypto level to understand more. Wikipedia of Commitment Schemes (https://en.wikipedia.org/wiki/Commitment_scheme) will give you more on the data that the holder gives to the issuer to be put in the credential and later proven.

swcurran (Wed, 16 Sep 2020 14:23:45 GMT):
On the TRUST_ANCHOR question -- I believe that is the generic Indy term for Endorser that is used in my definition above.

swcurran (Wed, 16 Sep 2020 14:24:47 GMT):

Hi everyone, I have a question about Indy's api calls about proof creation and verification. In order to prove that multiple credentials have the same attribute value without disclosing the attribute, "add_common_attribute" funtion of Ursa may be used. However, as far as I know, there is no way to add such functionality or trigger to call function "add_common_attribute" from Indy's api calls. Am I wrong?

swcurran (Fri, 18 Sep 2020 15:00:46 GMT):
The terminology is not precise. Master Secret is what is used in credential exchange. Master Key I think in this context is the wallet key -- the key for encrypting/decrypting items in the wallet/storage. Both are known only to the Holder/Prover. The Master Secret (aka Link Secret) is used to prove the Prover created the value that was put into the issued credential.

AryamaI (Fri, 18 Sep 2020 15:08:06 GMT):
@swcurran please confirm so at the start of agent only master key is als generated? no way for a user to see rehat his wallet maste key is?

AryamaI (Fri, 18 Sep 2020 15:08:06 GMT):
@swcurran please confirm so at the start of agent only master key is also generated? no way for a user to see what his wallet master key is?

swcurran (Fri, 18 Sep 2020 17:58:41 GMT):
I think that is the case, but I'll ping @andrew.whitehead to confirm.

andrew.whitehead (Fri, 18 Sep 2020 18:06:55 GMT):
The master key can refer to a couple things. You can use a wallet password, in which case it derives a wallet encryption key using argon2 each time you open it. You can also configure the wallet with a raw 32-byte key and bypass the key derivation.

andrew.whitehead (Fri, 18 Sep 2020 18:09:20 GMT):
Actually I don't think aca-py exposes a way for you to use a raw key, that's only at the lower level. But the encryption key is derived directly from the wallet password

AryamaI (Sat, 19 Sep 2020 03:15:17 GMT):
Thank you for the explanations @swcurran and @andrew.whitehead

avi23 (Sat, 19 Sep 2020 07:30:26 GMT):
Thanks @andrew.whitehead so does is mean that master secret key is also getting generated internally in the process and as developer we don't have to do anything extra here?

sheru (Tue, 22 Sep 2020 12:35:12 GMT):
once the nodes running in the local machine most probably you will get see the services on port 9000. you can found the genesis info in localhost:9000/genesis , use this path and run the aca-py agent and pass the genesis url in the envs of the docker.

AryamaI (Tue, 22 Sep 2020 12:45:04 GMT):
Hi @sheru , the ports exposed are from 9701-9708. Even so. I cant see the genesis info in any of these ports when trying to open from browser

swcurran (Tue, 22 Sep 2020 18:52:36 GMT):
The port 9000 web service is a feature of von-network, so you don't get that with plain indy. You need to get a genesis file for the configuration you have -- with the correct IP addresses and ports. I think (but am not certain) that is available in folder where the nodes are running. I would think the Indy docs for starting up a raw network would cover from where to get the genesis file. Once you have that, you need to copy it somewhere that the ACA-Py agent can get to it and use the mechanism to use GENESIS_FILE with the path to the file.

You don't need the genesis files to start the nodes, but you need it to start the instances of ACA-Py that you are running.

swcurran (Wed, 23 Sep 2020 16:06:08 GMT):
The error you are getting is that the IP address is probably wrong. You need to determine the IP address of the nodes (their public IP) and edit the genesis file to put those in.

On the mailing list for Indy, there was a proposal to move Absa LibVCX under the Hyperledger umbrella, and possibly to remove the libvcx folder that currently sits under Indy SDK. How can we make a formal decision on the proposal? Should we put it to a vote on a community cal, or vote on it here, or something else?

swcurran (Fri, 25 Sep 2020 18:32:17 GMT):
I personally would not use an internal indy node network for a production app. A key component of decentralized identity is that the keys are publicly available and not controlled by one entity. Sovrin governs the mainnet, but the nodes are operated by many different organizations.

AryamaI (Fri, 25 Sep 2020 18:39:37 GMT):
Ok thank you @swcurran for the input

Hello @esplinr , thanks for sharing the link above, I have checked it and see the transactions are for schema, credenital_defs. Can you tell me if I want to store not these standard indy data but rather ike store lets say some transaction done outside of indy, but store that transaction info on indy ledger like a financial transaction or something like that as an immutable record onto the ledger.

esplinr (Tue, 29 Sep 2020 13:22:49 GMT):
Indy is an identity specific ledger.

esplinr (Tue, 29 Sep 2020 13:22:58 GMT):
So you would have to model the data as an existing Indy transaction.

esplinr (Tue, 29 Sep 2020 13:24:26 GMT):
Another approach is to creating a ledger plugin for your needs. This is a good example: https://github.com/sovrin-foundation/token-plugin

esplinr (Tue, 29 Sep 2020 13:25:05 GMT):
Or you can use indy-plenum as a general purpose block-chain without the indy-node transactions. https://github.com/hyperledger/indy-plenum/

esplinr (Tue, 29 Sep 2020 13:27:09 GMT):
I would like to hear more about your "financial transaction data" use case. There are a few groups working on similar problems: https://github.com/hyperledger/indy-hipe/pull/160

AryamaI (Tue, 29 Sep 2020 13:30:25 GMT):
@esplinr when you say model data as indy transaction that means either make a create schema, create credential definition transactions something like this rt . But I can't do a custom transaction?

esplinr (Tue, 29 Sep 2020 13:31:03 GMT):
Correct. Indy excludes custom transactions to discourage people putting random junk on the ledger.

AryamaI (Tue, 29 Sep 2020 13:35:41 GMT):
@esplinr The problem statement which we are looking into is a transaction done between two peers in a network, where before making the transaction the peers are both validated using indy identity. Once validated transaction happens and then store the transaction info onto the blockchain indy ledger if possible

AryamaI (Tue, 29 Sep 2020 13:35:41 GMT):

Once validated transaction happens and then store the transaction info onto the blockchain indy ledger if possible

esplinr (Tue, 29 Sep 2020 13:38:26 GMT):
The identity information isn't stored on Indy. The credential is defined on Indy, and the identity information is transmitted peer-to-peer. This preserves individual privacy. It also makes it easy to use those credentials as part of any workflow, such as validating participants to transactions on a separate DLT network.

esplinr (Tue, 29 Sep 2020 13:38:55 GMT):
But if you really wanted to store additional information on Indy, then the best approach would be to write a ledger plugin.

esplinr (Tue, 29 Sep 2020 13:39:56 GMT):
https://github.com/hyperledger/indy-plenum/blob/master/docs/source/plugins.md

AryamaI (Tue, 29 Sep 2020 13:48:41 GMT):
@esplinr can you confirm if on the indy test/mainnet this new transaction type(plugin) functionality we can implement.

esplinr (Tue, 29 Sep 2020 13:50:43 GMT):
There is no Indy Test / MainNet.

esplinr (Tue, 29 Sep 2020 13:50:54 GMT):
Do you mean the Sovrin StagingNet / MainNet?

AryamaI (Tue, 29 Sep 2020 13:51:02 GMT):
Yes

esplinr (Tue, 29 Sep 2020 13:51:02 GMT):
You would have to propose the usage of your plugin, and get enough stewards to accept it.

esplinr (Tue, 29 Sep 2020 13:51:30 GMT):
The Sovrin network is designed to not allow non-identity transactions. Stewards don't want to be responsible for that data.

AryamaI (Tue, 29 Sep 2020 13:52:43 GMT):
Ok. If this functionality we want to incorporate then we can do it in our own network ledger rt as per the documentation?

esplinr (Tue, 29 Sep 2020 13:53:49 GMT):
It is possible, but might not be the preferred approach. In general, I would favor managing the data separate from the identity stuff.

esplinr (Tue, 29 Sep 2020 13:54:10 GMT):
You need to be careful to avoid correlation that undermines privacy.

AryamaI (Tue, 29 Sep 2020 13:55:24 GMT):

pfeairheller (Tue, 29 Sep 2020 21:28:37 GMT):
I am trying to submit write transactions to Sovrin buildnet and for that I need to provide the TAA. For that I need the acceptance mechanism. When I attempt to read the mechanism list (TXN #7) I am getting no results. I'm using indy_vdr for these transactions. Any help would be greatly appreciated!

pfeairheller (Tue, 29 Sep 2020 21:52:35 GMT):
Being the impatient guy that I am I kept poking at this. At first I found the following article https://sovrin.org/preparing-for-the-sovrin-transaction-author-agreement/ and assumed that maybe the mechanism could be _anything_. So I passed something and got an error. And happily I found in the error message the following: `"Txn Author Agreement acceptance mechanism is inappropriate: provided session_instantiation, expected one of ['at_submission', 'click_agreement', 'for_session', 'on_file', 'product_eula', 'service_agreement', 'wallet_agreement']`.

Using the indy-cli works to get the AML using `ledger get-acceptance-mechanisms` so you might be able to find example code in the indy-sdk/cli code to help. Start here maybe? https://github.com/hyperledger/indy-sdk/blob/master/cli/src/commands/ledger.rs

I know that in order to connect to it from outside all I need is the genesis.txn file from it, and the client will connect on it's own. But what would happen if I, let's say have two servers, A and B. Ran the docker on A, creating the genesisA.txn file, transfered the file to B, and used it as the genesis file for creating the pool in B. What would happen?

esplinr (Fri, 02 Oct 2020 15:44:20 GMT):
The genesis file should contain the information for all the initial pool nodes.

Hi everyone. I'm new here. I'm a recent graduated and I attend the last year of the master’s degree in Telecommunications and Informatics Engineering. I’m currently developing my dissertation with the theme "evaluation of blockchain technology in Identity Management context in Mobility as a Service". I already have a network to test (Hyperledger Indy), but I have some doubt. Some Hyperledger links don't redirect to the source code, like https://github.com/hyperledger/indy-sdk/blob/master/docs/how-tos/write-did-and-query-verkey/README.md Can you help me?

Hi Folks! I wanted to have a comparative differentiation between hyperledger indy vs Uport of Consensys vs Metadium, I have asked this question on the sovrin forum https://forum.sovrin.org/t/metadium-vs-sovrin/1496 here is the link and I still don't have answers. Indy and Metadium support multiple dids whereas uport supports only single did right?

vasantkk (Tue, 06 Oct 2020 13:23:34 GMT):
There are dozens of identity-related blockchain projects out there, and everytime we hear of a new blockchain-ID project we roll our eyes thinking, “another one?!” Civic, SelfKey, Metadium, Blockpass, VeriME, uPort, Sovrin, UniquID, BlockAuth, and the list goes on and on. How to differentiate from all these projects?

:point_up_2: I second @vasantkk question

daidoji (Wed, 07 Oct 2020 02:56:47 GMT):
I believe the idea is that by allowing multiple DIDs and DID methods wallets and agents aren't necessarily tied to infrastructure or particular implementations

daidoji (Wed, 07 Oct 2020 02:57:53 GMT):
that's just my beginner's understanding though. Other people should be more able to compare actual features and spec implementations of all these systems. You might try the W3C identity WG. I think they were discussing this on one of their mailing lists or chats

andrew.whitehead (Wed, 07 Oct 2020 03:34:51 GMT):
I’m not really sure what it means for a ledger to only allow one DID. In the case of Indy/Aries it’s encouraged to use single-purpose DIDs for communication between agents, which ought to be possible no matter what the backing identity ledger is. As for a comparison between the different ledgers, I’m not aware of one, but I’m sure it would be welcome.

what makes erc725 different from indy?

vasantkk (Wed, 07 Oct 2020 13:10:05 GMT):
or SSI as a concept?

daidoji (Wed, 07 Oct 2020 13:16:53 GMT):
erc725 is a set of identity standards for working on etherum. Indy is a ledger technology meant to work with W3C VC as implemented with DIDs. SSI is a broad concept that covers lots of different forms of decentralized identity systems and how to go about making those systems useable on the Internet.

daidoji (Wed, 07 Oct 2020 13:17:15 GMT):
but like I said, the W3C Identity WG I think has a document or something you can ask about with an FAQ on all these things (or should)

daidoji (Wed, 07 Oct 2020 13:17:50 GMT):
I'm not even guaranteeing my answers are correct as I'm pretty new to this space as well and there are some subtleties.

How does sovrin ensure that the Issuer is not fake and not giving out fake certificates?

daidoji (Thu, 08 Oct 2020 13:42:43 GMT):
@vasantkk If the issuer is not trusted in the ecosystem then people will not accept its certificates. If the issuer is attempting to impersonate another issuer (like a fake US gov't issuer issuing passports) then they will likely not hold the right keys that the US gov't signs in its issuing documents (or delegates)

swcurran (Thu, 08 Oct 2020 18:16:45 GMT):
@daidoji has it right. Anyone can issue credentials to holders, and holders can present them to verifiers. That allows the verifier to trust what they get from the holder -- they can't be tampered with, are bound to the holder and the issuer is known. What the verifier has to decide if they trust the issuer. They may know the issuer because they only accepted credentials from certain issuers, or they have to somehow (there are techniques) for deciding if the issuer can be trusted. This the human trust side of VCs. As noted, an issuer can pretend to be another issuer without taking control of the identifier (and associated keys) used to issue the credential.

is indy a blockchain/ledger or a did standard a bit confused from this article https://medium.com/linum-labs/the-whos-who-of-decentralized-identity-systems-433b2dd9a195

swcurran (Fri, 09 Oct 2020 12:56:09 GMT):
Indy is an open source ledger focused on identity, and in particular, verifiable credentials. You can run an instance of Indy to operate a ledger, such as the ones operated by sovrin.org. It is a "generic" blockchain underneath (plenum RBFT). with a transaction interface (indy-node) that limits the types of transactions to those specifically related to identity and verifiable credential use cases. Entities (people, organizations, things) run agents that communicate with the ledger to read and write data. It is public (anyone can read) permissioned (nodes of the network are permissioned to join consensus).

vasantkk (Fri, 09 Oct 2020 13:18:56 GMT):

vasantkk (Fri, 09 Oct 2020 13:51:33 GMT):
for private key recovery does indy use shamir secret key sharing for recovery?

swcurran (Fri, 09 Oct 2020 17:41:38 GMT):
The current indy-sdk has a storage component ("indy-wallet") that supports exporting an encrypted version of wallet data with a key. What you do with that is up to you, so it would be a higher level component that would implement the storage of the export and how to handle the key for recovery. So recovery strategies are at a layer up from Indy.

lijiachuan (Sat, 10 Oct 2020 11:09:06 GMT):
hi @swcurran , I would like to have your suggestion about another scenario of sharing digital identity, for example, to be able to use one service provided from one service provider, user needs to provide some identities such as name, email or even bank information, we know that this needs to be shared securely with user's consent, and when user doesn't want to share this any more, he/she can revoke this consent. Is there any recommended approach to implement this? Traditionally this information is shared and stored in service provider's database, am not sure whether there is any other better way. Kindly advise. Thanks.

swcurran (Mon, 12 Oct 2020 08:24:16 GMT):
There is nothing inherent in SSI for the use case you are defining. The user has been issued some credentials. A verifier asks the user for proof of those credentials via a proof request. The user (holder/prover) decides to construct provide and send the proof. At that point, the verifier has received the data and can do with it what they want -- there is nothing in the technology to prevent that, and there is nothing the holder/prover can do to "revoke" having given over the information. Think of the same scenario with paper credentials -- showing your driver's licence. You can't go back later and say "Forget that I showed you my licence". Where this goes is the governance framework under which the participants are operating (if any). Under what conditions (e.g. GDPR, etc.) was the proof requested, and the proof sent. Finally -- to be clear, an issuer of a credential can often revoke the credential to prevent the holder/prover from being able to continue to prove the credential they were issued.

Is there a way to resolve the key at timestamp=x? I don't think indy-vdr exposes any such API (yet?). I'm curious to know if that's a limitation of the current design or it is by design? @danielhardman @andrewwhi

@MathewJoseph Which version of RN are you using? This is a problem with react-native > 0.61.5 currently. We're having the same problem with aries-framework-javascript. See https://github.com/facebook/react-native/issues/29930 and https://github.com/react-native-community/upgrade-support/issues/114 . So assuming you're on RN > 0.61.5 for now the "fix" will be to downgrade to version 0.61.5

@TimoGlastra I am using RN 0.63.2 for my project. Oh now it all makes sense i had a sample project of 0.61.5 and open pool was working fine in it but when i integrated it to the main app it started crashing even though everything was same.

Most performance test results are captured in the tickets linked to https://jira.hyperledger.org/browse/INDY-1343 Such as https://jira.hyperledger.org/browse/INDY-1717 Then we largely rolled it into our regular testing process with video discussions: https://www.youtube.com/watch?v=984qU5q9e1Y&list=PLRp0viTDxBWGLdZk0aamtahB9cpJGV7ZF&index=46 https://www.youtube.com/watch?v=tyEDaeeUgfA&list=PLRp0viTDxBWGLdZk0aamtahB9cpJGV7ZF&index=38 https://youtu.be/OSpssHQXlOI https://www.youtube.com/watch?v=G-qlQkRJVWo  We haven't done as much performance testing in 2020, as the pace of development has slowed.

Hi I am currently facing issues on Native iOS after installing pods and adding requisite files to the project, after following indy integration steps still it throws this error `error: module compiled with Swift 4.2.1 cannot be imported by the Swift 5.3 compiler /Users/IndySdk/ios/Pods/libindy-objc/libindy-objc/Indy.framework/Modules/Indy.swiftmodule/arm64.swiftmodule. `Libindy-objc` is not maintained frequently it seems. What can be done here, Can we expect a new release to avoid swift compiler error !?

gnarula (Tue, 27 Oct 2020 07:28:52 GMT):
yeah, I ran into the above as well. Unfortunately the only way around it for now is to build libindy-objc yourself using the xcode/swift you have locally to avoid version conflicts

pavanMude 1 (Tue, 27 Oct 2020 08:05:12 GMT):
@gnarula Thanks for your response, Can you please elaborate, the procedure that you had followed while dealing with this issue and how did you overcome this error!? I appreciate your help here.

gnarula (Tue, 27 Oct 2020 08:20:35 GMT):
@pavanMude 1 Clone indy-sdk from https://github.com/hyperledger/indy-sdk and cd into `wrappers/ios/libindy-pod`. Do a `pod install` there and then open the `Indy.xcworkspace` file using XCode. Build the `Indy` Project and then Archive it. View the archive in finder, right click, show archive-contents and then copy 'Indy.framework' from '/Products/Library/Frameworks' and import it to your iOS project

pavanMude 1 (Tue, 27 Oct 2020 08:35:35 GMT):
@gnarula Thanks for your help, I will give a try then.

pavanMude 1 (Tue, 27 Oct 2020 09:03:16 GMT):
@gnarula While installing pods from cloned `libindy-pod` project, it throws warning `[!] The Podfile contains framework or static library targets (Indy), for which the Podfile does not contain host targets (targets which embed the framework).` Do you have idea why it is happening !?

daidoji (Tue, 27 Oct 2020 17:56:57 GMT):
this might be a silly question, but what will be the broad differences between `did:indy` and `did:sov`?

daidoji (Tue, 27 Oct 2020 17:58:23 GMT):
or what is the motivation for `did:indy`?

swcurran (Tue, 27 Oct 2020 18:13:44 GMT):
The main motivation is that `did:indy` will have a component to identify the network instance on which to resolve the DID. That is missing from `did:sov`. So an indy did will like look something like this: `did:indy:7GF4e:1231243wer...` where the `7GF4e` is derived from a hash of something that will identify the network. The exact mechanism to be used is to be determined.

swcurran (Tue, 27 Oct 2020 18:14:39 GMT):
That allows DIDs to be resolvable on any published Indy network -- Sovrin, Sovrin Staging, IDUnion, etc.

daidoji (Tue, 27 Oct 2020 18:45:45 GMT):
ahhh, that makes sense. Thanks!

Good day! I was wondering if it's possible to create a proof predicate comparing strings? I attempted setting the predicate to "=" and received the error telling me that it must be any of ">=","<=","<",">", so I was wondering if that is possible with proof predicates or only in attributes? Thanks

esplinr (Wed, 28 Oct 2020 12:47:43 GMT):
Currently it only supports integer comparisons, so the string has to be encoded as an integer. There is work underway to define those encodings on the ledger, but it's not done yet.

swcurran (Wed, 28 Oct 2020 12:57:16 GMT):
Trickier yet -- a sortable encoding.

Lucampelli (Wed, 28 Oct 2020 13:28:21 GMT):
for now I'm just decimal encoding the string, so the way would be to encode the string and use it in two predicates? One <= and the other >=. because if it's true on both it means its ==. Right?

swcurran (Wed, 28 Oct 2020 13:34:15 GMT):
That works. Note that there is also a `restriction` that you can use for the equality of the value if that is all you are looking for.

Lucampelli (Wed, 28 Oct 2020 14:01:33 GMT):
How do I use then? Can't seem to find it in the docs...

I'm going through @esplinr 's indy-cli How-to to access sovrin buildernet. And I'm stuck in the step to write a schema. I set taa mechanism to be for_session in the cliconfig file. What else do I need? pool(buildernet):my_wallet:did(XD7...wvv):indy> ledger schema name=vswFirstSchema version=1.0 attr_names=FirstName,LastName,Address,Birthdate,SSN Transaction author agreement Acceptance Mechanism isn't set. pool(buildernet):my_wallet:did(XD7...wvv):indy> pool(buildernet):my_wallet:did(XD7...wvv):indy> ledger txn-acceptance-mechanisms aml={"taaAcceptanceMechanism":"for_session"} version=2.0 Transaction has been rejected: Not enough TRUSTEE signatures

wenjing (Wed, 28 Oct 2020 21:35:34 GMT):
Btw, here is the How-to I was following, except I ignored the payment-address, guessing it's no longer required. https://sovrin.org/wp-content/uploads/Token-Test-Instructions.pdf. What am I missing? Thanks!

Lucampelli (Wed, 28 Oct 2020 21:57:53 GMT):
which restriction? right now I could only find that it restricts for schema id and other things but not the value

swcurran (Wed, 28 Oct 2020 22:52:08 GMT):
Restrictions come in 6 forms: - schema ID - schema Issuer (DID) - Cred Def ID - Cred Def Issuer (DID) - attribute name (e.g. claim name) - attribute value So if you Cred Def ID and attribute value, you have the equivalent of an "equal" predicate. You are exposing the data, but that's OK if it's equality you are after -- if you a claim is equal to value, you know the value.

Lucampelli (Wed, 28 Oct 2020 22:52:24 GMT):

Thanks. embarrassingly silly. Can i safely skip the token plugin now for buildernet and stagingnet? Just want to get a confirm to be sure.

brentzundel (Thu, 29 Oct 2020 16:43:55 GMT):
on staging net and builder net you have the option of either use the token plugin, or to use transaction endorsers

brentzundel (Thu, 29 Oct 2020 16:45:17 GMT):
this website can help you get setup with tokens or endorser status on staging net: https://selfserve.sovrin.org/

wenjing (Thu, 29 Oct 2020 16:54:18 GMT):
Ok. I plugged in DID and verkey (again left the payment address field blank) in the selfserve page and it seems to work. Once this DID becomes an endorser, it can do write operations without tokens. Is that right understanding?

brentzundel (Thu, 29 Oct 2020 16:54:43 GMT):
that is correct

wenjing (Thu, 29 Oct 2020 16:57:32 GMT):
Thanks! very helpful to clear up some doubts. Is there a good place to figure out how the mainnet handle payments? like api definition?

brentzundel (Thu, 29 Oct 2020 16:58:07 GMT):
tokens are not currently used on mainnet, all transactions need to be signed by an endorser

wenjing (Thu, 29 Oct 2020 17:00:44 GMT):
I see. Presumably the endorser would create a "normal" payment account with sovrin to handle fees? Are there any other conditions for anyone to become an endorser?

brentzundel (Thu, 29 Oct 2020 17:02:11 GMT):
That is my understanding, but for specifics you'll need to reach out to Sovrin directly. I'd recommend asking questions on chat.sovrin.org

wenjing (Thu, 29 Oct 2020 17:03:27 GMT):
Great! Will do. Thanks so much for clearing it up for me.

wenjing (Thu, 29 Oct 2020 17:37:15 GMT):
Another problem popped up. The "ledger cred-def" command requires "primary" which is said to be the "primary key in json format". What is this? how to find it or create it?

lynn.bendixsen (Thu, 29 Oct 2020 17:58:29 GMT):
The `ledger cred-def` command cannot be run from the indy-cli without using an external program to build/create the primary key. I suggest switching completely to code to reliably create the cred-def.

lynn.bendixsen (Thu, 29 Oct 2020 18:00:21 GMT):
payment address is optional for writing txns to the network, but is required if you are testing token functionality.

wenjing (Thu, 29 Oct 2020 18:48:52 GMT):
Thanks. That's what I thought as I follow the How-to coding series in the doc. By the way, for anyone who wants the details - the anoncred paper is where the ultimate answer is. The indy-cli tutorial probably should find a way to remove its reference by a higher level of simplification.

HI i am working on a RN project which uses indy. I am trying to implement the issue credential flow and the second phase of generating the credential request from prover side is causing issue for me. I debugged the java code in android studio and found that the issue is happening in the rust indy api lib. https://github.com/hyperledger/indy-sdk/blob/a21383cb960a008ce5ba976a2054c323696b5946/libindy/src/api/anoncreds.rs#L945 The param check in the indy_prover_create_credential_req api function is throwing invalid structure error

TimoGlastra (Tue, 03 Nov 2020 14:34:46 GMT):
Hi all, I have a question related to requesting proof for multiple credentials of the same type. E.g. lets say, as a holder, I have 10 vaccination credentials in my wallet. All from the same schema, but different credential_definitions. Each credential represents a single vaccination I received. When I go to my doctor I want to show proof of all received vaccinations. It seems like this is not possible with the current version of indy. Has anyone already put any thought into this scenario? Seems like a somewhat common use case, that I’m curious to see how it will work

daidoji (Tue, 03 Nov 2020 14:36:53 GMT):
you can show them one at a time? Do you want to combine proofs?

TimoGlastra (Tue, 03 Nov 2020 15:01:39 GMT):
One at a time would be possible, but this introduces some overhead and (I think) also eliminates the possibility to check all credentials are issued to the same holder (using link/master secret)

daidoji (Tue, 03 Nov 2020 15:06:26 GMT):
I agree on the overhead, on the second part I think you would just need to keep state. No reason that you can't check their provenance all originates with the same holder.

daidoji (Tue, 03 Nov 2020 15:06:47 GMT):
although maybe I'm misinformed about that. I am pretty new to this project

WadeBarnes (Tue, 03 Nov 2020 15:20:46 GMT):
You need to use the `--config` option when starting the `cli`: https://github.com/hyperledger/indy-sdk/blob/master/docs/configuration.md#options

WadeBarnes (Tue, 03 Nov 2020 15:21:18 GMT):

dgt1nsty (Wed, 04 Nov 2020 14:04:14 GMT):
is trustee and trust anchor are the same thing?

dgt1nsty (Wed, 04 Nov 2020 14:05:33 GMT):
if it is according to doc of sdk becoming a Trust Anchor requires contacting a person or organization who already has the Trust Anchor role on the ledger

swcurran (Wed, 04 Nov 2020 16:19:02 GMT):
A trustee is the highest level access on the system and are (usually) required for creating any elevated role DIDs, and for operations that affect the network -- e.g. initiating upgrades of the software run by the nodes. An Endorser (formerly Trust Anchor) can write or endorse the writing of "regular" DIDs (DIDs with no special privileges) and verifiable credential related objects (schema, cred def, rev reg and rev entries). An endorser may have to sign a legal agreement, and pay for any transaction that they endorse. Those are required by Sovrin. The roles are configurable, as are the number of signatures required.

Hi, I am building an identity solution for my school and we want it to be following a common standard that is universally verifiable. I have a few questions, will be great if I can get a response - 1. Does using Indy also mean I am compliant with w3c VC standards? 2. We are planning to go ahead with sov which provides me with a did of type sov, should I be looking at aries implementation? 3. When Indy too has a concept of channels authcrypt and decrypt etc. Is there a reason why I should look at aries? 4. Can I monitor the transactions of did type sov in the Indy scan net?

swcurran (Tue, 10 Nov 2020 02:35:12 GMT):
Don't have the instruction handy, but there is a command that dumps the config rules. Perhaps on the ledger you are using it takes more than one Trustee to add a Steward?

swcurran (Tue, 10 Nov 2020 02:35:48 GMT):
If not that, then I would check on whether the DID you are using is a Trustee DID.

I've a question around an Indy read transaction's state proof. The multi_signature timestamp refers to the timestamp the state was last updated at right? I wonder if the state is still updated and that timestamp changes irrespective of any transactions being posted on to the ledger every fixed time interval? A quick analysis suggests so but I wanted to be sure

gnarula (Thu, 12 Nov 2020 07:37:50 GMT):
and is the time interval 5 minutes at the moment?

AlexanderHoughton (Fri, 13 Nov 2020 18:42:20 GMT):
Hi all, I've been developing an Android Aries agent mplementation, along with a corresponding issuing/verifying agent server in Express.js and C++, on Windows. On the server side, try as I might, the C Indy function callbacks don't seem to be called, and I've been coding C/C++ for 24 years, so I'm at a bit of a loss as to why. As a temporary measure, I am talking to Indy by using ZeroMQ socket connections to the Indy Node.js wrapper and as insane as it sounds, this is working rather well. :) The Android app is working nicely, and works with pretty much all of the BC Gov. issuers and verifiers, such as the Unverified Person Issuer and the Health Gateway verifier. The server acts as a router when dealing with the BC sites and also works as an issuer for several test credentials. I am almost done adding credential verification functionality to the server and have made sure that the schema_id, cred_def_id etc. are correctly used as keys for the corresponding JSON array entries, where needed. Indy is no longer yelling at me about missing or malformed data, but it would appear that the signatures do not match as 'false' is returned from Indy.verifierVerifyProof. The encoded values in the issued credential match the values in the proof json (which I'm assuming is good), so I am rather confused as to what the problem is. I've attached the following: Verifying_Problems__Issued.txt - JSON console log of issued credential Verifying_Problems__Verifying.txt - JSON console log of data sent to JS call indy.verifierVerifyProof Verifying_Problems__Node.js - JS function call that calls Indy.verifierVerifyProof. I've been through the ACA Py source code, stared at anoncreds.rs (I don't know Rust), and generally tried to figure this out, but I am embarrassed to admit that I'm rather stuck. Please help, so that I can get this fixed and move on to implementing credential revocation. Many thanks in advance.

Hi everyone. I am in trouble with how key rotation works on Indy. In key compromise case it is clear. However, when everything is valid, how does it work? If an issuer issues a credential and then rotates its keys before verification process, how can a verifier verify this credential?

daidoji (Mon, 16 Nov 2020 13:52:21 GMT):
I think the credentials issued with the compromised key can't be verified at that point.

Hello, I'm currently looking through Indy documentation and wondering what the status of this page is: https://github.com/hyperledger/indy-node/blob/master/docs/source/requests-new.md ? It's named "new", yet changes are 16 month ago(and therefore older than the requests page). Can anyone comment on the status of this?

swcurran (Tue, 17 Nov 2020 00:50:20 GMT):
Some central concepts about this. Authorizations on the ledger are configurable, so in theory, the answer to your questions may be affected by the configuration of the specific ledger. That said, in general the terms with the permissions are "Trustee", "Steward" and "Endorser" (formerly "Trust Anchor"). In general, Trustees will create all Stewards and Endorsers. Stewards will ONLY be able to do operations that affect their node of the network, and would NOT create Endorsers. Further, Endorsers can create DIDs for Authors (no ability to create other DIDs), but that's it. To your questions: 0. Change "Steward" to "Trustee" across the intro and the questions. 0. "a" is an Endorser and cannot create "b" another Endorser (caveat -- MAYBE the rules can be set up for that, but unlikely). 1. A Trustee may have authority to remove the "Endorser" privilege of "a" to just an Author. A Trustee cannot change the verkey of the Endorser, and cannot delete the DID altogether. 2. Since "b" can only be created by the Trustee (not "a" unless "a" is a Trustee), the Trustee can operate as per the paragraph above about "a". 3. There is no "delegation" flow involving the two DIDs -- they are independent of one another. Hope that helps.

Hello experts, I have a generic question, I am not sure if this is the right place to ask about it. In Verifiable Credentials, how a VC is correlated with an entity like a user? I read about Blinded Linked Secrets? but I could not find a lot of information about it anywhere? I am really surprised that such proving ownership is not talked about a lot in the documentation s and the W3C standards? Am I missing something? Does Hyperledger Indy have a different method for VC ownership? is there a documentation i am missing that explain those concepts?

NYM verkeys are easy to be rotated regularly and serve for connection establishment. I'm unsure what you mean with master key. The link secret?

paul.bastian (Thu, 19 Nov 2020 14:15:25 GMT):
Indy uses anoncreds. Credentials are not issued to a certain DID, but to the blinded link secret. the holder proves that 2 credentials belong to him by presenting the same signed link secret in both creds

Thank a lot Paul. I see now. But I have two questions: First, is this protocol fips compliant or has any sort of compliance or validation done to it? Second question which is not related: When an Issuer signs a Verifiable credentials (which include the blinded link secret), what DID public key is it signed with? is it the pairwise DID with the holder? or is it a special kind of DID that is published on the blockchain? In other words? does the Issuer use the same published DID for DID connections? or those are separate?

paul.bastian (Fri, 20 Nov 2020 15:10:30 GMT):
communication connection is done with DID public keys which translates to NYM verkeys, credential signing is done with credential definition CL keys

What is the maximum number of transactions per second that can be written to the hyperledger indy?

pankajn (Mon, 23 Nov 2020 12:40:30 GMT):
credential offer

esplinr (Mon, 23 Nov 2020 15:11:58 GMT):
In 2019, we proved a sustained load of 10 writes per second on a 25 node cluster while serving thousands of reads per second.

bstsc (Mon, 23 Nov 2020 21:14:09 GMT):
Yes, which is used to produce NYMs.

pankajn (Tue, 24 Nov 2020 08:50:59 GMT):
In the getting started example (https://github.com/hyperledger/indy-sdk/blob/master/samples/python/src/getting_started.py) anoncreds.issuer_create_credential_offer (at line 274) returns a Credential Offer for Alice. This I believe is the connection invite. I am unable to link this code to the creation of pairwise DID (as I was expecting). Would really appreciate if someone could point out in the code where in the process of creating a connection invite do pairwise DID get created.

TimoGlastra (Tue, 24 Nov 2020 09:19:01 GMT):
Indy SDK doesn't know about the concept of connections. Hyperledger Indy concerns with the issuing, holding, proving and verifying of credentials. It can also create and manage keys for you, which can be used in connections. Hyperledger indy doesn't concern with exchange of credentials or DIDs. Connections are a concept from Hyperledger Aries, for which you can use one of the available aries frameworks (aries-cloudagent-python, aries-framework-dotnet, aries-framework-go, ...)

pankajn (Tue, 24 Nov 2020 09:20:22 GMT):
ok I see. Many thanks, much appreciated!

Lucampelli (Tue, 24 Nov 2020 12:57:29 GMT):
Thanks for the reply, but accessing the docker image via: "docker run --rm -it --entrypoint=/bin/bash indy_pool" the only folder inside /var/lib/indy is sandbox, and there is no data in it...

rrishmawi (Tue, 24 Nov 2020 13:59:58 GMT):
Hey Paul, i really thank you for your answers. I have another question if you can answer: How relying party (verifier) do trust some issuer in a DID worlds? I am familiar with the concept of governance trust frameworks and members directory, and that those might be hosted on a blockchain, but how technically a relying party can find the list of trusted issuers (anchors) and who signs them?

lynn.bendixsen (Tue, 24 Nov 2020 15:09:19 GMT):
Sorry @Lucampelli I don't know Docker well enough yet to answer that one.

This docker file installs it for ubuntu 18 (https://github.com/hyperledger/aries-framework-javascript/blob/master/Dockerfile). I've changed 18 to 20 and libindy itself installs fine.

I have faced the same problem and changed the indy-pool.dockerfile in the ci directory as follows: 1. add aptitude and apt-utils to the install environment 2. change the versions of each module as follows: #ARG indy_plenum_ver=1.12.1~dev989 #ARG indy_node_ver=1.12.1~dev1172 ARG indy_plenum_ver=1.13.0~dev1220 ARG indy_node_ver=1.13.0~dev1220 ARG python3_indy_crypto_ver=0.4.5 ARG indy_crypto_ver=0.4.5 ARG python3_pyzmq_ver=18.1.0 3. change the installation command after the "ARG" section: RUN apt-get update -y && aptitude install -f -y \ python3-pyzmq=${python3_pyzmq_ver} \ indy-plenum=${indy_plenum_ver} \ indy-node=${indy_node_ver} \ python3-indy-crypto=${python3_indy_crypto_ver} \ libindy-crypto=${indy_crypto_ver} \ ursa \ python3-ursa \ vim With those changes, I was able to build the docker image. It also starts properly. However, I'm running into a different problem now, don't know if this is related to my changes. (Credential definition is panicking, no idea if this is caused by using different versions as in the original file, will have to figure this out).

ManfredM (Sun, 29 Nov 2020 13:43:03 GMT):
Ok, just tried with the following changes to the dockerfile (note that the indy_plenum and indy_node versions are as in the original version on github): ARG indy_plenum_ver=1.12.1~dev989 ARG indy_node_ver=1.12.1~dev1172 ARG python3_indy_crypto_ver=0.4.5 ARG indy_crypto_ver=0.4.5 ARG python3_pyzmq_ver=18.1.0 ARG python3_orderedset_ver=2.0 ARG python3_psutils_ver=5.4.3 ARG python3_pympler_ver=0.5 RUN apt-get update -y && aptitude install -f -y \ python3-pyzmq=${python3_pyzmq_ver} \ python3-orderedset=${python3_orderedset_ver} \ python3-psutil=${python3_psutils_ver} \ python3-pympler=${python3_pympler_ver} \ indy-plenum=${indy_plenum_ver} \ indy-node=${indy_node_ver} \ python3-indy-crypto=${python3_indy_crypto_ver} \ libindy-crypto=${indy_crypto_ver} \ ursa \ python3-ursa \ vim It builds, it runs, but I still have the panic error when creating cred defs (using Java wrapper).

ManfredM (Sun, 29 Nov 2020 13:47:32 GMT):
Hi Experts, has anyone been able to run the file found in https://github.com/hyperledger/indy-sdk/blob/v1.11.0/samples/java/src/main/java/Anoncreds.java without problems? I get a panic error message: "thread '' panicked at 'attempted to leave type `linked_hash_map::Node` uninitialized, which is invalid', /build/rust/src/rustc-1.48.0-src/library/core/src/mem/mod.rs:658:9" I have also got the full stack trace, if it helps. The panic occurs in line 53 of the file: AnoncredsResults.IssuerCreateAndStoreCredentialDefResult createCredDefResult = issuerCreateAndStoreCredentialDef(issuerWallet, issuerDid, schemaJson, credDefTag, null, credDefConfigJson).get(); Any hints what I could do about that? I'm running a local indy docker image, using a locally built libindy, debug version (from indy-sdk project). However, the same error also occurs when I use libindy-1.15.0-1 from Arch User Repos. (The stack trace says a little more with the locally built version, though, the AUR version is a release version without debug info).

Hi All, I was wondering if anyone could point me to documentation around which port ranges/ports are used for indy nodes in the node pools in the various networks (builder, staging, mainnet). Based off the genesis files, we can see ports such as 9701, 9702 etc. But is there any explicit spec or documentation around this? This matters a lot for network firewalls and what traffic we should be allowing through. Thanks!

WadeBarnes (Sun, 29 Nov 2020 22:01:37 GMT):
9700-9799 is the complete range of possible ports.

Hello, I am a dapp developer on Ethereum but a completely newbie on Hyperledger. I am currently developing a dapp and planning to integrate Hyperledger Indy identity management system into my dapp. Just wondering if Indy is open to anyone to use, or is there some specific process that I have to go through before I could start using it?

daidoji (Mon, 30 Nov 2020 16:53:28 GMT):
indy is open to anyone to use but indy is the name of the technology, instances of indy (like the Sovrin chain `did:sov` method) each have their own protocol for integration if you want write access. Usually the public has read access.

brentzundel (Mon, 30 Nov 2020 17:27:24 GMT):
A schema is a small JSON object, whose size varies according to the number of attributes, each of which is a single string. Conversely, a cred def is a large JSON object, with a 256-bit integer for each attribute in the schema. a cred def for a schema with 2 attributes will be much smaller than a cred def for a schema with 20 attributes. Are you noticing the time difference between cred defs of similar size, or are the cred defs differently sized?

brentzundel (Mon, 30 Nov 2020 17:35:04 GMT):
The rules for what permissions are required to create DIDs of different roles are different for each ledger. On Sovrin main net, a Steward does not have permission to create an Endorser (Trust Anchor). An Endorser also does not have permission to create another Endorser.

Hi @wip-abramson thanks for the reply! My dapp is a ticketing system on Ethereum (so we could regulate the secondary market etc). I would like to integrate some sort of decentralised identity management use case to the dapp for events attendees, so I just come across Indy. But since I'm new to hyperledger everything seems quite foreign to me right now haha. So would like get started on learning indy and also understand whether it is possible to integrate a permissioned identity management into a dapp built on a permissionless network

Hi KaushalIngle, author here. It's running on indyscan.io prety stable against Sovrin networks, in past I've encountered issue where indysdk was reporting no new transactions on the ledger, even though there actually were. Perhaps it was ledger issue, or maybe something in indysdk, I don't know. It didn't happen for several weeks now. In general it's running with minimal devops maintenance on my side for couple months.

PatrikStas (Tue, 01 Dec 2020 14:37:51 GMT):
As for the stability of the code and APIs, it can change, there's features I would like to add and it might require changes how the data is stored.

On Sovrin main net, a Trustee must sign the transaction to create an Endorser. I'm not sure what the auth rules are for the other Sovrin networks. I do know that indy-cli has a command to retrive the auth rules ( I think it is: `get_auth_rules`)

Hello everyone. I couldn't find any demo / tutorial about creating a PoC app using Indy-SDK (Java wrapper) to connect to Sovrin network. For now, I don't want to deploy my own network. Can anyone help me with some resources / directions? Thx

swcurran (Mon, 07 Dec 2020 14:31:26 GMT):
You can get an Endorser DID on the Sovrin BuilderNet or StagingNet from this site -- https://selfserve.sovrin.org/ You can ignore the payment address pieces. For production use case with Sovrin MainNet, there is a formal process to get an Endorser DID and transaction fees associated with using it.

Hi everybody. Hope this question fits to this channel since it is about mobile mobile wallet apps: I found this Sovrin elaboration by @danielhardman regarding disaster recovery for mobile wallets (https://sovrin.org/wp-content/uploads/2019/03/What-if-someone-steals-my-phone-110319.pdf). A "device revocation feature" is mentioned, which I do not find in any other "not Sovrin" docs so far. Is this a (still existing) "Sovrin only" feature, or is there some equivalent in the general Hyperledger Indy space? And if there is not: When a wallet apps offer some kind of export / backup functionality, how can one make sure, that the backup is not imported as copy to a wallet app of a total different user (in order to "copy" identities)? I am pretty sure, that this is not the first time this kind of question was posted, but I would appreciate any hint very much...

Alexandru-MihailAdam (Thu, 10 Dec 2020 13:55:46 GMT):
I'm trying to write a schema on the Builder Network on Sovrin. I received a endorser DID, used it, but when i'm trying to submitRequest i get the following error: `{"op":"REQNACK","reason":"client request invalid: insufficient number of valid signatures, 1 is required but 0 valid and 1 invalid have been provided. The following signatures are invalid: did=KgHAvbiM4y6RHqJZHx2EGX, signature=2TEPnSQRUNmTjAj8zfQukTXqX7fZpQBKzyoAdAXqR5VJC1bG61vy6Zmy6RqzxX11VRLMtwQAh9JJyXwop9aD1zKH","reqId":1607608160786862225,"identifier":"KgHAvbiM4y6RHqJZHx2EGX"}`

Alexandru-MihailAdam (Thu, 10 Dec 2020 13:56:32 GMT):
I'm the Author of the transaction, also the endorser. Should I make another operations ?

Alexandru-MihailAdam (Thu, 10 Dec 2020 14:15:23 GMT):
PS: I checked my DID on indyscan.io as a NYM tx and it's published on the ledger

ArturPhilipp (Thu, 10 Dec 2020 14:30:06 GMT):
Are you using Indy CLI for the schema transaction? Are you connected to the correct pool (buildernet)?

Alexandru-MihailAdam (Fri, 11 Dec 2020 06:35:51 GMT):
No, I'm using Java SDK. I tried with Indy CLI and it works, but from SDK, it doesn't.

Hi Guys, Just a quick question, is there an example of revocation implemented in aries ? How do i go about implementing revocation in aries ?

ArturPhilipp (Fri, 11 Dec 2020 09:34:31 GMT):
no worries :)

daidoji (Fri, 11 Dec 2020 14:07:14 GMT):
There's an #aries channel and one for each client too that you might have better luck if you're asking for specifics. That being said the aries-cloud-agent does have revocation example in their demo.

awais.ahmad (Fri, 11 Dec 2020 14:08:28 GMT):
@daidoji thanks! I will google what that one is.

awais.ahmad (Fri, 11 Dec 2020 14:09:22 GMT):
ah ok you mean python agent

daidoji (Fri, 11 Dec 2020 14:11:33 GMT):
well more like the REST agent haha, but yeah. acapy is the shorthand name.

awais.ahmad (Fri, 11 Dec 2020 14:14:03 GMT):
thanks. I appreciate it. I am trying to translate that agent to the dotnet framework and it doesnt seem to have an implementation of revocation.

swcurran (Fri, 11 Dec 2020 14:58:30 GMT):
Aries Cloud Agent Python has full support for revocation as an issuer/verifier, so you can use that. I'm not sure of the status in the other frameworks. The /demo directory has some example code showing revocation in action.

ianco (Fri, 11 Dec 2020 15:00:21 GMT):
(It's documented in the "AliceGetsAPhone" demo)

rileyphughes (Fri, 11 Dec 2020 15:01:28 GMT):
@awais.ahmad aries framework dotnet does support revocation.

Lucampelli (Mon, 14 Dec 2020 11:34:49 GMT):
Thank you, still, my original question remains. Is the trust anchor role revokable? And is it Transitive if so?

Hi all. I decided to try some of the indy tutorials directly after learning a bunch through #aries-cloudagent-python. I am trying the getting-started one (https://hyperledger-indy.readthedocs.io/projects/sdk/en/latest/docs/getting-started/run-getting-started.html) from a freshly cloned copy of `indy-sdk`, launching from the `indy-sdk/docs/getting-started/` directory. Bringing up the network via `docker-compose up` fails with the following error. Looks like version problems for `indy-plenum` dependencies. I haven't tried to fix this on my own yet - but thought this group might like to know since it's the most basic walkthrough piece a newcomer might encounter. ``` The following packages have unmet dependencies: indy-plenum : Depends: python3-orderedset (= 2.0) but 2.0.3 is to be installed Depends: python3-psutil (= 5.4.3) but 5.6.6 is to be installed Depends: python3-psutil (= 5.4.3) but 5.6.6 is to be installed Depends: python3-pympler (= 0.5) but 0.8 is to be installed E: Unable to correct problems, you have held broken packages.

deas (Tue, 15 Dec 2020 21:36:51 GMT):
Just realized this may have been a better fit for #indy-sdk and checked there. Sure enough - problem was reported and answer was found. See the thread here https://chat.hyperledger.org/channel/indy-sdk/thread/cWq34By6rBvyGkAiR?jump=q4KbJYrDTrPqeCmwf Basic gist: need to edit the `indy-sdk/ci/indy-pool.dockerfile` (to pin appropriate versions of the dependencies) and `indy-sdk/docs/getting-started/docker-compose.yml` (to get f-strings support on Python 3.6). Issue's open on github, so I trust this'll get included soon.

paul.bastian (Fri, 18 Dec 2020 12:58:07 GMT):
Translation from Indy network data to DID doc is handled in the sovrin DID Method so far, and you can use a n ATTRIB for adding a service endpoint. However this is pretty outdated and there is currently a group working on a brand new Indy DID Method that will work for all indy networks

andrew.whitehead (Tue, 22 Dec 2020 06:54:22 GMT):
I think you need to substitute whatever docker's internal host IP address is, von-network uses this to find it: `docker run --rm --net=host eclipse/che-ip`

andrew.whitehead (Tue, 22 Dec 2020 06:55:04 GMT):
instead of 127.0.0.1

Shweta1 (Tue, 22 Dec 2020 07:23:28 GMT):

At least 4 nodes are required. Docker networking can be complicated, I can't really diagnose that. Also you don't need to rebuild the docker image for each node

Shweta1 (Wed, 23 Dec 2020 12:49:58 GMT):
Thanks andrew,it's working with 3 nodes.I diagonose the problem.Actually I am starting node by providing IP 127.0.0.1 it should be 0.0.0.0 like this "start_indy_node Node1 0.0.0.0 9701 0.0.0.0 9702 &".YesI dont need to create separate image.Thanks a lot again

1. you should ask indicio directly for best answers :) 2. yes, it's HL indy based 3. you can connect via instructions on their website https://indicio.tech/indicio-testnet/ or, the easiest way is to sign up for a trinsic account and use a trinsic cloud agent (based on aries) http://trinsic.studio 4. credentials issued from one network need to be verified using that same network. however an agent that issues credentials on Sovrin could also verify credentials coming from Indicio or visa-versa. Hope that makes sense

Hello! To answer your specific question: To add a TRUSTEE you must use an existing TRUSTEE DID. Depending on how the Auth_rules are set up, you might need more than one TRUSTEE signature to add a new TRUSTEE. The screenshot you sent adds a little bit of confusion, though. A Trust Anchor is not the same as a TRUSTEE. The older term "Trust Anchor" has been replaced by "Transaction Endorser" (or in a lot of the doc's it's just referred to as "ENDORSER") Adding an ENDORSER DID to your test ledger also requires one or more TRUSTEE signatures.

I am assuming that there's did doc from every DID that libindy generates because of this document: https://sovrin-foundation.github.io/sovrin/spec/did-method-spec-template.html And the peer did: https://identity.foundation/peer-did-method-spec/

Hi @lynn.bendixsen thanks! I managed to figure out the DID of a trustee, and it's seed, thus I was able to add my very own trustee. For everyone, here's your clue: http://greenlight.bcovrin.vonx.io/browse/domain 1. Run a new node using von-network. 2. Browse localhost:9000/browse/domain and look for DID that is marked as trustee 3. Hunt the seed of that DID in google 4. build_nym_request --> role='TRUSTEE' and send via sign_and_submit_request

Simply put: - 1. I found this DID: V4SGRU86Z58d6TV7PBUe6f with a role of trustee. - 2. Thanks to google, I found it's seed: 000000000000000000000000Trustee1 - 3. Generate a DID using create_and_store_my_did and use the seed above - 4. Control your indy node!

swcurran (Tue, 05 Jan 2021 00:47:45 GMT):
For 1, the answer is yes and no :-). Within LibIndy, there are three elements associated with the DID -- the verkey (public key), the private key and the DID identifier. The latter is derived from the first verkey for a DID, so if you change the verkey and private key (e.g. rotate the keys), the DID identifier remains the same. A DIDDoc can be constructed using three elements, but there is literal document stored. Once you publish the NYM to an Indy Ledger, a resolver (such as the universal resolver) will retrieve those elements and return a formatted DIDDoc. If you also add an ATTRIB to the ledger with an "endpoint" as the data value, the Universal Resolver will include that as a fourth element of the DIDDoc. Likewise, an endpoint can be added to a Peer DID. 2. There is a private key. Libindy does not give you a way to get that, as it would be insecure. The less handling of the private key the better.

The idea is: 1. Create a schema 2. Create a credential definition **Create Schema** anoncreds.issuer_create_schema ledger.build_schema_request ledger.sign_and_submit_request **Create cred def** (cred_def_id, cred_def_json) = await anoncreds.issuer_create_and_store_credential_def Send the: cred_def_id and cred_def_json to the prover Here's your guide: https://github.com/hyperledger/indy-sdk/blob/master/docs/how-tos/issue-credential/python/issue_credential.py#L102

ghabxph (Tue, 05 Jan 2021 08:15:53 GMT):
Now, I haven't fully explored Aries yet, but I think the idea is to send that cred def id and cred def json to the prover to send the link secret and so on.

Lucampelli (Mon, 11 Jan 2021 12:41:10 GMT):
Good Day! I would like to ask if Credentials ever make to the public Ledger, or are they only stored in the wallets of the one who created it and the one who received it?

Lucampelli (Mon, 11 Jan 2021 13:00:04 GMT):
Good Day! A question that popped up was: Considering one's wallet is stored in a physical medium in one's possession, be it a computer (with the Indy Client), a SmartCard, a SmartPhone whatever. What can be done to recover a wallet in case of device destruction? Would indy be working side by side with another Ledger in order to keep track of all credentials and DID's for this case?

daidoji (Mon, 11 Jan 2021 14:07:40 GMT):
@Lucampelli , I think Indy was designed so that credentials never go on the ledger. Just public dids, revocation registries, schema defs, credential defs

daidoji (Mon, 11 Jan 2021 14:08:13 GMT):
As to where they're stored, I think that's entirely up to the good faith of the issuer, verifier, and holder

swcurran (Mon, 11 Jan 2021 15:10:27 GMT):
As @daidoji noted, the credentials are issued to the holder and held in their secure storage. That storage can be backed up and restored as needed. That said, both the secure storage of the credentials, and the handling of the backups has to be done with care to prevent others from getting access to the private keys and the credentials. As noted, the credentials never go on a ledger -- the ledger holds identifiers and public keys of issuers and metadata about the credentials -- credential schema and revocation data.

lynn.bendixsen (Mon, 11 Jan 2021 16:50:30 GMT):
Which "data" are you referring to? Just the ledgers? What I usually recommend is to get a complete snapshot so that the node can be restored quickly to contribution level. The data for the ledgers themselves are restored automatically from other nodes within a short period of time of restarting, even if the ledgers need restored from scratch.

etaleo (Tue, 19 Jan 2021 11:56:12 GMT):
I've wanted to see how DID documents are stored on Indy (if at all), but it seems that there are stored some kind of credentials (?) For example, in the GET_ATTRIB example in https://github.com/hyperledger/indy-node/blob/master/docs/source/requests.md you can request the "dateOfBirth" attribute. Where is this dateOfBirth coming from? (Is it some part of a VC? I don't think so, as there is no VC specified, and in my understanding VC aren't stored on the ledger.) What is it exactly that is stored as "NYM" (and referenced by a DID) in Indy (in the context of SSI)?

etaleo (Tue, 19 Jan 2021 12:09:51 GMT):
So, as far as I understand, Indy does not follow the concept of DID documents and Verifiable Credentials (yet) as specified by W3, but instead has a different way of handling identites and related information to them, right? I'm still confused about where the similarites and differences are exactly.

TimoGlastra (Tue, 19 Jan 2021 12:19:36 GMT):
`dateOfBirth` is an example attribute. To my understanding an ATTRIB is just a key value storage tied to a did. If you for example look at the universal did resolver for `did:sov` it uses a get nym + get attrib to retrieve the did + endpoint (https://github.com/decentralized-identity/uni-resolver-driver-did-sov/blob/main/src/main/java/uniresolver/driver/did/sov/DidSovDriver.java#L148-L202). There is currently being worked on a `did:indy` method that does align with the DID spec, however I believe it will still use nym and attrib requests under the hood

etaleo (Tue, 19 Jan 2021 12:37:42 GMT):
Thank you. How is Indy able to resolve the dateOfBirth request, or in other words how does Indy know where the information is stored / how does Indy relate the information to the DID?

All, trying to do some performance testing credentials issuance with revocation registry size as 50K, It is taking approx 3 mins just to create the Credentials Definition and then 5 mins just to issue a single credential. So it is too slow. But with no revocation registry credential issuance is almost immediate. I am using aries-cloudagent:py36-1.14-1_0.5.1 and using 4 node Indy VON Network from https://github.com/bcgov/von-network. Wallet database being used here is SQLLite only. The CPU and memory utilization are all with in the limit, don't think it has any thing to do with infra. Any pointers on how to optimize this ?

Question about https://jira.hyperledger.org/browse/IS-1545 and https://jira.hyperledger.org/browse/INDY-2327 and a wider question that doesn't seem to have a clear answer. What exactly is the delta between W3C VC spec and Indy credentials? I know enough to know that they're different but don't know enough to know how to list out all those differences. Is it just this Rich Schema context that's missing or what? Is there a list somewhere or is this something I just have to crawl the specs for to determine myself?

daidoji (Thu, 21 Jan 2021 16:10:59 GMT):
The second looks like a bug but normally one doesn't need to mess with the genesis file I don't think so I'm not exactly sure what safeguards there are around that. Can both servers write to the same ledger that you're using??

x0axz (Thu, 21 Jan 2021 16:19:17 GMT):
no.. different servers and different ledger

daidoji (Thu, 21 Jan 2021 16:21:00 GMT):
ahh then the issue is that those public dids are bound to the ledger. If you create the did on one ledger and then try to use it on an issuer that's reading from the second ledger you're likely to get a failure.

swcurran (Thu, 21 Jan 2021 20:03:41 GMT):
Indy credentials are not W3C standard. The signature schema (CL Signatures) could be made W3C standard, but that has not been done, and there was some work on that with Rich Schema, but I believe that has been abandoned. Our plan (ACA-Py/BC Gov and others) is to instead move to BBS+ Signatures with JSON-LD to both achieve W3C Standard format with ZKP and Selective Disclosure support. To now, none of the W3C Standard formats or implementations (other than BBS+) achieves ZKP or selective disclosure, which we think is crucial. We continue to use Aries using Indy VCs for now because (a) the tech stack is rich and complete and interoperable based on Aries Interop 1.0, (b) there is a large community of collaborators and deployments, and (c) the Aries protocols give us a the protocols needed to exchange credentials and proof while evolving the VC payloads (e.g. from Indy Anoncreds to BBS+). Hope that helps.

daidoji (Thu, 21 Jan 2021 20:07:55 GMT):
@swcurran that helps a lot. Did the Aries-Go implementation take another route? Like where do Indy Anoncreds end and the Aries interop profile say begin?

swcurran (Thu, 21 Jan 2021 20:11:36 GMT):
AFGo skipped the use of Indy, anoncreds and the AIP 1.0 protocols. Until recently they did not support ZKP or selective disclosure, but recently added support for BBS+, which will provide those capabilities. On the down side, because they skipped Indy and AIP 1.0, we're not able to use AFGo in any use cases with ACA-Py or the Aries.Net framework. We expect that to change over the next few months, but it's going to be a bit yet.

daidoji (Thu, 21 Jan 2021 20:51:10 GMT):
@swcurran thanks again. Here's another question that might help clear up the last bit of misunderstanding I have. Lets say there's another credential format tomorrow. "ieee vc" or something like that. Would the AIP be able to support that too? Like are the credential formats (and crypto primitives) tightly bound to the protocols?

swcurran (Thu, 21 Jan 2021 20:56:03 GMT):
The goal of Aries 2.0 is to make it easy to extend. The credential exchange protocols define the interactions, and leave the payloads open, so that handlers for different payloads (formats) can be added, and the protocols still work. Of course, a specific deployment would have to have support for the format and it's underlying crypto (no magic :-) ), but it can be plugged in, and the protocols allow negotiation about what format to use -- e.g. payloads that both support. So an offer might say -- "I have a credential to give you and I support formats anoncreds, JWTs and ieee vc -- what format do you want?"

daidoji (Thu, 21 Jan 2021 21:05:37 GMT):
okay, I think that makes more sense.

daidoji (Thu, 21 Jan 2021 21:06:13 GMT):
right now though acapy could only say "I support anoncreds" and aries-go can only say "I support w3c vc jwts" right?

wip-abramson (Fri, 22 Jan 2021 10:14:14 GMT):
This is an interesting thread. I am wondering what is the point of supporting the VC Data Model for the credential side with signature schemes like CL and BBS+. The whole point is creating a fresh presentation each time so no one needs to interoperate with my VC. I see the value in moving towards a standard presentation format. Maybe I am missing something though, is the idea that it makes it easier to move wallets?

I think the ideal of the VC data model is to not be locked down to one particular implementation (or standard spec).

daidoji (Fri, 22 Jan 2021 14:26:00 GMT):
Like in an ideal future I can take any credential in the wild, it'll be spec'd to VC data model, a few standard crypto primitives, and I'll be able to use those primitives and the data model without caring how its generated

daidoji (Fri, 22 Jan 2021 14:33:51 GMT):
I mean it depends on your use case, but in general all the agents mediator or not, would need to be able to read from the same ledger (and write if they're establishing new credentials or public dids)

swcurran (Fri, 22 Jan 2021 15:01:31 GMT):
Agree with the ideal, but the phrase "a few standard crypto primitives" is where it gets interesting. That has to be balanced with a desire to have a VC with attributes like ZKP and selective disclosure. TLS-style crypto doesn't get you those characteristics, but it is achievable with crypto that has been around since the early 2000s and is used elsewhere. Where do you draw the line?

wip-abramson (Fri, 22 Jan 2021 15:20:06 GMT):
Yeah you can only take the credentials with advanced crypto is you "understand" how to. Very different from just storing essentially a document with a signature against it. So my question is why go to the effort of conforming to the data model for the credential object. Whats the value add?

swcurran (Fri, 22 Jan 2021 15:27:17 GMT):
Wow, Will, I'm impressed. A question like that on a Friday afternoon. :-) It is a good question. I think the drivers of the standard started with the ideal above, decided they didn't need the "fancy" stuff and went ahead. That said, BBS+ Signatures does allow sticking to the format while achieving the desirable characteristics. But at the cost that the parties must support that crypto. And on it goes...

wip-abramson (Fri, 22 Jan 2021 15:49:00 GMT):
Hahahaha yeah it certainly feels like the VC Data model was never designed with this crypto in mind. I guess standards are always a compromise. I would love to follow along with the work going into BBS+ in aca-py. Did you select someone to work on this contract yet?

Hi all, a Pool with Steward Role is running on AWS server controlled by me. Now, I wanted to add multiple Trust Anchors, which are running on different servers. I did one experiment, I used the genesis file form AWS Server in Trust Anchor server (which has 4 nodes with Steward Server IP), and didn't start docker and was able to Create Schema & Credential Definition. Now, I've some questions. 1) Was that a right approach? if not, then what's the right way to create network like this? 2) Is there any need to run a docker on Trust anchor (I didn't run earlier)? 3) To add the Trust Anchor, have to add node_ip of the Trust Anchor's server in genesis file on Steward server? 4) How to add and remove the Trust Anchor in network? 5) How to generate DID for Trust Anchor? 6) If network is running, and I have add a new Trust Anchor, how to add it? Is there anything else I should know about?

Hi all, I’ve finished what I believe is an interesting document describing an effective solution for the SSI Personal Data Usage Licensing (SSI-PDUL) problem and would appreciate your comments and feedback. You can edit a Google Docs copy of my Word master version of the whitepaper here: https://docs.google.com/document/d/1yP0OgDhq-3TTIien5gsETi4jZdyiKbwE/edit If you prefer to read a PDF version, you can download it from here: https://hyperonomy.com/2021/01/27/self-sovereign-identity-personal-data-usage-licensing-ssi-pdul-model-solution-concept-review-draft-0-27/ One, what I believe to be an authoritative, comment that I’ve received so far is: Otherwise, I think it's a pretty unstudied problem. Abstract The purpose of this solution concept whitepaper is to provide the first complete description of the motivations, key concepts, problem statement, and solution approach for implementing the Self-Sovereign Identity Personal Data Usage Licensing (SSI-PDUL) Model, a functional component of the Self-Sovereign Identity Model (SSI Model). This solution concept addresses the following user scenario: How Alice User, an App User and Identity Owner, and Bob Developer, an App Developer and App Controller, might negotiate the use of Alice’s personal digital identifiers and any associated personal identity data by Bob’s app, based on Self-Sovereign Identity Model Usage Principles. The scope of the Self-Sovereign Identity Personal Data Usage Licensing (SSI-PDUL) Model is personal digital identifiers and any associated identity data presented by Alice to the App. It does not include the permissioning of data internal to the App (although the natural extension of the solution to internal data is an obvious one). The intended audience for this whitepaper is a broad range of professionals interested in furthering the application and use of the SSI Model in software apps, agents, and services using an SSI Personal Data Usage Licensing (SSI-PDUL) Model approach. This includes software architects, application developers, and user experience (UX) specialists; as well as people involved in a broad range of standards efforts related to decentralized identity, verified credentials, and secure storage. The work documented here was performed under the auspices of the Trusted Digital Web project in the Hyperonomy Digital Identity Lab of Parallelspace Corporation.

The scenario is bootstrapping an app with a copy of a VC for you as "Member" or "Citizen" of the app. The attributes would only be shared within the app on a traditional SSI selective disclosure basis ...so it the very initial use case where you're claiming an instance of a mobile or desktop as "your own" ...an identity bootstrapping process ...where you're not beholding to any issuer or service provider once the credential has been issued. You can take it and present it to any app you want to.

I don't really see how that would work, as the credential wouldn't have any binding to the new identity you're creating. Maybe if it was self-issued at the onset.

mwherman2000 (Mon, 01 Feb 2021 00:53:08 GMT):
Alice User would initially use an Issuer to get her Member or Citizen credential then she would persist it to some sort of secure, password protected file format like PKS12.

madhugoundla (Tue, 02 Feb 2021 18:28:44 GMT):
Thank you, let me try the von network. Where is the indy setup rules documentation?

daidoji (Tue, 02 Feb 2021 18:37:51 GMT):
not sure, in the docs somewhere but it is a bit disorganized. Maybe someone else can show specifically. von-network is probably the path of least resistance though.

lynn.bendixsen (Tue, 02 Feb 2021 23:36:09 GMT):
The von-network is a great place to start to learn about and test an Indy network. When you are ready, though, I have some documents that can help you to set up your "production" network. Start here: https://docs.google.com/document/d/1Tg4dAEtC78TxG9AsIby_CfpbeOicK_YMKznSQOvtIVU/edit

Have you tried restarting? `./manage stop`, `./manage start AWS_MACHINE_IP_ADDRESS WEB_SERVER_HOST_PORT=80 "LEDGER_INSTANCE_NAME=My Ledger" &`

zossimov (Thu, 04 Feb 2021 20:51:48 GMT):
I used `./manage down`.. let me try it

WadeBarnes (Thu, 04 Feb 2021 20:52:26 GMT):
That is typically an indication one or more nodes have not started correctly or the browser container has not connected to the nodes. The latter can be a timing issue where the nodes have not completely initialized before the browser starts and tries to connect.

zossimov (Thu, 04 Feb 2021 20:57:11 GMT):
after using `./manage stop`, the loading stopped, but now again loading started.. why?

WadeBarnes (Thu, 04 Feb 2021 21:21:58 GMT):
`./manage down` deleted that volumes. `./manage stop` leaves them intact. Start von-network. Leave it for a bit. It can take a minute or so for everything to initialize. If, after a few minutes, it still says `loading`. Use `./manage stop` , and then start it again. Typically the nodes will come up faster and things will initialize in the right order.

WadeBarnes (Thu, 04 Feb 2021 21:33:28 GMT):

pasting this from #general : What is the the most expedient means to get going with publishing a DID document to the ledger? I found this: https://github.com/hyperledger/indy-sdk/blob/master/README.md which seems to be a prerequsite for this https://sovrin.org/wp-content/uploads/Token-Test-Instructions.pdf . I hope I am not confusing hyperledger indy and sovrin though. Evernym built indy, sovrin uses it along with its governance. afaik. I'd imagine new stuff is never easy. I think. Oh wow, this seems heavy. I'm dowloading 200MB of files, installing Rust, etc. Is there a docker image for everything or just for a local pool, or is a local pool all I need? I imagine the answer is somewhere along the lines of: it depends. If it helps, the machine I'm using is a beast (circa a few years ago). The pipe out of the net is small though.

swcurran (Fri, 05 Feb 2021 00:51:33 GMT):
So -- some thoughts. Indy does not support the DID spec, focuses mainly on verifiable credential exchange using AnonCreds, where only the Issuer of VCs needs to have a DID on the ledger. To create a DID on a public ledger, you can use the Indy CLI to generate a DID and then go to https://selfserve.sovrin.org/ to publish it. The same process occurs on Sovrin MainNet, but requires more legal overhead -- the governance. To add more to the DID (such as an Endpoint), you can use the CLI. However, most people are using Indy because they want an agent to issue, hold, prove or verify VCs. For that, you would probably want to get into Aries. In other words -- just creating a DID on a public ledger is not really "a thing" in Indy -- it's usually associated with VCs, and for VCs, there is a lot more moving parts. Hope that helps get you to the next step...

Our Requirement!!! We want multiple Issuers (who can offer/issuer/reject/revoke credentials) on different servers, connected to a pool on our main server. we would be the only one who can add/remove issuer. Is it possible?

Couldn't find Sovrin BuilderNet and StagingNet..

WadeBarnes (Fri, 05 Feb 2021 16:42:06 GMT):
`von-network` would meet those requirements other than the permission bit. There are no permissions/rules setup on it to stop someone who knows the default seed from doing whatever they want.

hi everyone, as the SSI ecosystem grows, we feel there is a growing need for a standardized wallet security ecosystem and therefore a working group called "Wallet Security" is to be launched under DIF umbrella. In particular we think that: - we should get a common understanding, terminology about wallet security in the community - talk about wallet security architectures to analyze similarities - create a specification and interface to communicate about wallet capabilities, security, regulation-conformance and other points of interoperability - define mechanism to enable wallet security assertions, certification and ways to prove them - define specifications about wallet user authentication, ways how to ensure them and how to communicate them to issuers/verifiers If you are interested about this topic and like to comment, participate, criticize: - please review the Wallet Security WG Charter: https://docs.google.com/document/d/18H2hVjHZEBjbnzod8tLogJIEzySdecbk9d-QBJaqHP0/edit - subscribe to the mailing list: https://lists.identity.foundation/g/wallet-security After gathering initial feedback, we will have an open discussion meeting soon. I hope this is in the best interests of the community and will get the necessary feedback to make an impact. Best regards, Paul Bastian

Lucampelli (Thu, 11 Feb 2021 17:15:09 GMT):
Hello! Is it possible, in a scenario where, let's say that SSI (with Indy) was deployed on a country, for 2 people to have the same DID? In the Self Soverign Identity documents I've read from Indy and Sovrin, it's stated that a user can create as many DID's as it wants, and by studying the code a little, the creation of DID's is made offline, and if that DID needs to become public, it is made through the verynim steps described in the getting started. So, in my mind, it is possible for 2 distinct people to have credentials made for the same DID. Unlikely, but possible.

swcurran (Thu, 11 Feb 2021 17:20:23 GMT):
Define possible? :-). Bottom line is that it's not a concern and there is no need for centrally produced identifiers. I would suggest you look into UUIDs -- the same principles apply.

mwherman2000 (Thu, 11 Feb 2021 22:43:33 GMT):
When are Hyperledger Indy/Sovrin VCs better than Ethereum smart contracts for NFEs/NFTs (non-fungible entities/tokens)? It seems obvious but I don't have a detailed/worked out answer. One project I'm associated with wants to use the ERC-721 Non-Fungible Token Standard on Ethereum but I believe VCs are a better route to take. Part of the desire to stay on Ethereum is there is quite a vibrant NFT community on Ethereum and lots of different EC-721 tokens. What are the considerations/decision points/knock-offs? ...off to do some Googling.

mwherman2000 (Thu, 11 Feb 2021 22:46:04 GMT):
ERC-721 Non-Fungible Token Standard on Ethereum: https://eips.ethereum.org/EIPS/eip-721

abuaesh (Fri, 12 Feb 2021 06:39:06 GMT):
I believe you'd want to compare Indy with ERC725; the standard used for SSI on Ethereum. Here is what I missed after moving from working Ethereum to work with Indy: A vibrant community that hardly lets you go to sleep with unanswered questions. A solid ground of documentation and plethora of resources. They have at least one article for every problem you may run into. Now, I can get stuck in a technical problem for days and feel invisible when I ask questions here. I'm not sure if that's because I am using Windows(so not many people ran into the same problems), or because I am looking in the wrong places.

mwherman2000 (Fri, 12 Feb 2021 07:17:12 GMT):
@abuaesh It's the other way around: I want to do NFT better on Indy (using VCs) than either ECR-721 or ECR-1155 on Ethereum. Is this possible? ...can I do the same or better on Indy? What are the pros and cons?

abuaesh (Fri, 12 Feb 2021 10:22:12 GMT):
Yes, it is possible, since you can write anything really in a VC. You may want to check Indy plenum for that: a general purpose DLT. Indy node is just an identity-related implementation of plenum. Will it be better? I don't know tbh. I am still trying to get something to work on Indy!

Lucampelli (Fri, 12 Feb 2021 12:24:17 GMT):
Well, can two distinct people have in their wallets two similar DID's? Let's say you and I, you graduated university, created a DID for your diploma, eg. DID 1234, I completed a cooking course, and also created a DID for receiving the certificate, eg. DID 1234.

Hi @abuaesh, It looks like we need some more details to be able to help you with this one. Csn you tell us what kind of pool you are trying to connect to? (test pool, docker pool, von image, public existing ledger, etc.) Usually that error comes from networking problems, or an issue in the genesis file used to create the pool handle. :)

You might take a look at this: https://github.com/hyperledger/indy-hipe/tree/master/text/0011-cred-revocation It has a fairly accessible description of how revocation works with tails files and the like.

I am implementing aca-py with revocation but when I am starting faber with revocation it shows set tails base url. Can anyone please help me with how can I set tails base url.

RazaDen (Wed, 17 Feb 2021 07:48:46 GMT):
There is a command line parameter that you can supply to ACA-Py that tells it the URL of the tails server (separate process).

RazaDen (Wed, 17 Feb 2021 07:50:11 GMT):
Have a look at the following command line paremeters (as they are described by the help message of ACA-Py): ` --tails-server-base-url Sets the base url of the tails server in use. [env var: ACAPY_TAILS_SERVER_BASE_URL] --tails-server-upload-url Sets the base url of the tails server for upload, defaulting to the tails server base url. [env var: ACAPY_TAILS_SERVER_UPLOAD_URL]`

Hi guys! I'm new to the hyperledger indy stuff and trying to implement a blockchain which can be used in the documentmanagement area (e.g. to varify signatures on documents in the document flow of a company). I started at 0 with Linux Foundation courses and tried to follow the Tutorials mentioned there. I got confused going through the docs. In some for example Python 3.5 is necessary in some a version higher than 3.5, in some you can run commands in your direct local environment in some a VM is necessary and even there a venv is sometimes recommended. I wondered if this is a must? are there any special requirements for using indy? or does it only vary because of the different tutorials and years they were published? Would be really great if someone could help me in the indy jungle :) Thanks

abuaesh (Wed, 17 Feb 2021 12:43:09 GMT):
There is also Indicio

abuaesh (Wed, 17 Feb 2021 12:43:09 GMT):

Trying to connect to a pool on Sovrin, so public existing ledger. Yes, I was using an incomplete genesis file(didn't copy the whole file from github). Fixed it now. Thanks!

abuaesh (Wed, 17 Feb 2021 13:27:05 GMT):
A DID is 32 characters long. Each character can be a digit or an alphabet letter->36 possibilities per character. A chance to generate a duplicate is one in a 32 power 36 chance.

abuaesh (Wed, 17 Feb 2021 13:28:03 GMT):
It is helpful. Thanks!

Hi there T_anna, yes, it took me a while before I could pass the installation test for Indy. Are you using Windows?

swcurran (Wed, 17 Feb 2021 15:43:47 GMT):
do you have a tails server running? There is an implementation here: https://github.com/bcgov/indy-tails-server It is trivial to run locally if you have docker -- clone the repo and then run `./manage start`

lynn.bendixsen (Wed, 17 Feb 2021 21:12:37 GMT):
"Versions must have at least 1 dot in them", but could contain as many as 2, according to Adam Burdett. The version string must look like a version, apparently. I looked for documentation to support it, but was unable to find it. The error message, though confusing, strongly implies that is the case, though.

swcurran (Wed, 17 Feb 2021 21:39:35 GMT):
Easiest way to run in Indy is using von-network https://github.com/bcgov/von-network Assuming you have docker/docker-compose/bash, you can be running a ledger in about 5 minutes.

[ ](https://chat.hyperledger.org/channel/indy?msg=fuXcgfNNWYB6LzyPZ) I have done that already but still I am getting same error

RazaDen (Thu, 18 Feb 2021 09:10:47 GMT):
The tails server needs to have a "public IP", i.e., ACA-Py needs to be able to call it via its ip/domain name or w/e.

RazaDen (Thu, 18 Feb 2021 09:12:55 GMT):
Maybe that's the problem? Otherwise it's pretty straight forward. Let me give you an example where the tails server is configured to have a public endpoint, via ngrok: `--tails-server-base-url https://5cd2c2e7cde6.ngrok.io` This is for instance the parameter that we pass to one of our ACA-Py instances

@WadeBarnes at the moment I'm getting the pool sandbox error, mentioned above. Before that I tried to follow the IBM Tutorial, there I got errors that a specific version of docker, docker-compose etc. is necessary, which made no sense since I have the necessary versions installed.. Thanks a lot :)

lynn.bendixsen (Thu, 18 Feb 2021 17:03:14 GMT):
in other words, change "version=1" to "version=1.0" and your code should work.

WadeBarnes (Thu, 18 Feb 2021 17:42:53 GMT):
Are you able to get `von-network` up and running locally first? To the point were you're able to open the ledger browser and register a DID through the interface?

WadeBarnes (Thu, 18 Feb 2021 17:46:21 GMT):
Working example can be found here; http://dev.bcovrin.vonx.io/

Hi! Following this guide https://github.com/IBM-Blockchain-Identity/indy-ssivc-tutorial I get errors on my ubuntu 16.04 when trying to build the network saying "Error while fetching server API version". After googling this issue one suggestion was to follow another guide, since the IBM guide is archived. When following this https://github.com/hyperledger-archives/education/blob/master/LFS171x/indy-material/nodejs/README.md I get the following erros: "ERROR: for node4 Cannot start service node4: driver failed programming external connectivity on endpoint nodejs_node4_1 (2b46b52b453ef2b4edef405e993534d83a5a5a5d9b53aba2cfcf4435c8855f55): Bind for 0.0.0.0:9708 failed: port is already allocated ERROR: Encountered errors while bringing up the project. /usr/local/lib/python3.5/site-packages/paramiko/transport.py:33: CryptographyDeprecationWarning: Python 3.5 support will be dropped in the next release of cryptography.

T_aanna (Thu, 18 Feb 2021 18:49:52 GMT):
I'm also getting the info that python3.5 is outdated. This info is actually not true, since "python --version" returns Python 3.6.xx

T_aanna (Thu, 18 Feb 2021 19:18:31 GMT):
Update: after resetting my docker containers i ran the command a second time, network came up, got the page where I can authenticate a new DID. Am I now done? Is this now a running von-network? Sorry for the dumb question, but since I got so many errors and different tutorials I am confused if this is it now..

abuaesh (Thu, 18 Feb 2021 21:25:47 GMT):
Yes! It works now--I mean giving a different reason for rejection: "op":"REJECT","reason":"client request invalid: InvalidClientTaaAcceptanceError('Txn Author Agreement acceptance is required for ledger with id 1',)"}

WadeBarnes (Fri, 19 Feb 2021 14:50:26 GMT):
That means you have `von-network` running properly. Now you can try connecting the agent and see how far you get with what you were doing before.

lynn.bendixsen (Fri, 19 Feb 2021 16:27:05 GMT):
You need to send the txn to the functions that add the TAA to the txn before sending it to a ledger that requires TAA. I will see if I can find the docs or a code snippet to help.

abuaesh (Sat, 20 Feb 2021 16:05:08 GMT):
Just figured that the timestamp shouldn't be the exact current time of accepting the TAA, to reduce corratability risk. So, the timestamp should be the time of the start of the day of accepting the TAA. More about it here: https://sovrin.org/preparing-for-the-sovrin-transaction-author-agreement/ "Similarly, the application should not provide the time the user accepts, but only the day. Correlation risk can be further reduced by tracking a different acceptance date per DID on the ledger, or regularly asking the user to reaccept the agreement in order to change the acceptance date—although we acknowledge these approaches may increase the user’s friction when writing to the ledger."

How do we know that the credential offer goes ONLY to the designated person. What if the offer(or a copy of it) falls in the wrong hands? They will still be able to generate a credential request, and get issued the credential(unless if the issuer keeps a list somewhere of DIDs that are legible to this offer). Is there something I am missing in the steps because I can't find something that links the offer to its targeted recipient.

swcurran (Tue, 23 Feb 2021 18:50:04 GMT):
The "best practices" in that is that you establish a DIDComm connection with an entity, and then use that channel to get some sort of proof of who they are. If possible, you would use the channel to do a proof request. With that done, binding the channel to the proof, you would use the same channel to issue the credential via the offer-request-issue sequence in the issue-credential protocol. Note as well that with AnonCreds (assuming you are using that), in the Offer and Request there are crypto graphic elements that bind the two parties to the credential. So when you issue the credential to the entity, you are binding it to that entity, and they will be the only one that can present the credential.

swcurran (Thu, 25 Feb 2021 15:41:30 GMT):
That's not the role of Indy. You don't want to put data about individuals, even identifiers and public keys on any blockchain. What you can do with Indy is issue a verifiable credential to every citizen that allows them to prove their National ID without any need to have verifiers integrating with the National ID service. The identifier does not need to be given to the verifiers for many (most?) use cases -- they just need to know the the person is a citizen or resident.

Hi everyone, I was reading indy-plenum doc and I didn't get what these statements saying "Client-to-node and node-to-node communication happens on CurveZMQ. The codebase has an abstraction called Stack that manages communication. It has several variants which offer different features." I understand that messages are send back and forth by peers' corresponding transient public keys obtained using curvezmq and are generated by curve-keygen. But what does following statement is saying "codebase has an abstraction called Stack that manages communication". What Stack stands for in this context and how it manages the communication? Can you please someone eleborate this statement so that I can make more sense.

Hello! Are issued credentials stored also in the issuer's wallet? I mean, let's say Faber University Issued a Graduated Credential for me, will it also be stored in it's wallet? Or it depends on the implementation?

swcurran (Tue, 02 Mar 2021 19:25:20 GMT):
Depends on the implementation. In ACA-Py, there are three options for issued credential exchange record (which would contain the info in the credential). (1) Delete the record entirely, (2) keep the full exchange record in the wallet, (3) keep a minimal record that just contains just enough about the issuance to be able to revoke it using the ID of the record. Regardless, it is up to the controller to, for example, link the credential exchange ID to the entity your system that represents the holder. For example, Faber would keep in it's system the ID of the student and (at least) the ID the Credential Exchange ID so that if it needs to revoke the credential for the student it can find the information necessary to do so.

swcurran (Wed, 03 Mar 2021 15:28:39 GMT):
Sorry for the delay in respsonding. Have you read this document -- particular the part about the "interval" meaning in the proof, and the interval meaning in the query to the ledger? The differences between those create a lot of confusion and may be what you are seeing here: https://github.com/hyperledger/indy-hipe/tree/master/text/0011-cred-revocation

swcurran (Wed, 03 Mar 2021 15:30:18 GMT):
Basically, to create the proof of non-revocation, you have to have all of the deltas from ledger -- you have to know all of the inactive and revoked credentials so a witness can be constructed. If you don't get all of those, you can't make the proof.

vineeta (Wed, 03 Mar 2021 15:53:06 GMT):
yes I had checked this document wherein verifier sents the interval in non-revoked field but it doesnt explain about verification process. I had tried a scenario where proof is created by prover using now() as current timestamp for fetching delta (similar to what is done in indy-sdk samples/nodejs/revocationScenario) & at verifier this revReg object is created using timestamp from identifier as key So not clear on this part what does that timestamp mean. In this example delta is fetched based on current timestamp but timestamp key is from identifiers(timestampOfProof) https://github.com/hyperledger/indy-sdk/blob/8c669cff434f5d87e7a2e2e192423c67a9df0b33/samples/nodejs/src/anoncredsRevocationScenario.js#L418 https://github.com/hyperledger/indy-sdk/blob/8c669cff434f5d87e7a2e2e192423c67a9df0b33/samples/nodejs/src/anoncredsRevocationScenario.js#L464

I don't think the SDK provides a method to do that. Currently you have to manually edit the JSON of the revocation registry definition

Yes. You can update revRegDef['value']['tailsLocation'] before building request here. indy.buildRevocRegDefRequest(did, revRegDef);

Hi Guys, I have a few questions about indy. if someone can help would be great. How can you connect your indy node to sovrin network? if yes, will sovrin charge for connectivity? If I will issue a credential using evernym, will I be able to load that credential in any wallet like Trinsic ? What would you recommend in terms of building applications - indy connected to sovrin, trinsic or evernym ? If i will spin my own network of indy, are there any wallets that will work automatically with it?

Hi everyone, although it is widely agreed that we don’t put personal data of individuals on Indy, in case someone ends up putting personal data either accidentally or maliciously, is there a workaround to somehow take care of it? Also, can “Right to be forgotten” be somehow managed while using Indy?

deas (Mon, 22 Mar 2021 16:59:38 GMT):
I'd _really_ try to avoid a scenario where that's possible, personally. What are you using Indy for that enables someone to write personal data to the chain?

swcurran (Mon, 22 Mar 2021 17:25:20 GMT):
On Sovrin, there is an agreement with an Endorser and with an Author that explicitly excludes writing personal data to the ledger as a way to avoid the need for that. The only potential PII that could go Indy is an identifier (with nothing about that identifier controller/subject), and on Sovrin, only business entities where such an identifier is NOT personal are (legally) allowed to write to the ledger.

swcurran (Mon, 22 Mar 2021 17:26:04 GMT):
If those agreements are followed, there is no PII on the ledger, and not a need to be forgotten.

HighBrow (Tue, 23 Mar 2021 06:53:34 GMT):
@swcurran I agree that because of the legal agreement a business entity will not be writing any personal data on the ledger since that could have legal consequences. But in case of accidental writes, is there anything that could be done on the ledger?

HighBrow (Tue, 23 Mar 2021 07:00:27 GMT):
@deas I’m not enabling someone to write personal data on the chain. I am talking about the case when some personal data could actually land up on the ledger since as of now there are only legal implications that would discourage that to happen in the first place.

swcurran (Tue, 23 Mar 2021 13:51:43 GMT):
Correct. There has been a plan defined to "tombstone" data -- make it inaccessible from the network, but that has not been implemented. This link was posted to the feature overview: https://jira.hyperledger.org/browse/INDY-2082

Not sure which channel would be best for this question. I was attempting to stand up a DID resolver on Openshift 4. (Note that I am abandoning this and waiting on resolver being included in act-py; however, if there is an easy answer, that'd be great). This appears to be one of the many issues related to openshift and the image user accounts, but hoping I can get pointed to something more concrete that I can address. I know the files for my genesis transactions are on the image and in the location specified by my config. I have built and run the same image outside of Openshift and it works. But this is my error stack: ```m[qtp1262822392-12] WARN servlet.ResolveServlet (doGet) - Driver reported for did:sov:WRfXPg8dantKVubE3HX8pw: Cannot create pool config "_": org.hyperledger.indy.sdk.IOException: An IO error occurred. uniresolver.ResolutionException: Cannot create pool config "_": org.hyperledger.indy.sdk.IOException: An IO error occurred. at uniresolver.driver.did.sov.DidSovDriver.openIndy(DidSovDriver.java:334) at uniresolver.driver.did.sov.DidSovDriver.resolve(DidSovDriver.java:123) at uniresolver.driver.servlet.ResolveServlet.doGet(ResolveServlet.java:71) at javax.servlet.http.HttpServlet.service(HttpServlet.java:687) at javax.servlet.http.HttpServlet.service(HttpServlet.java:790) at org.eclipse.jetty.servlet.ServletHolder.handle(ServletHolder.java:865) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1623) at org.eclipse.jetty.websocket.server.WebSocketUpgradeFilter.doFilter(WebSocketUpgradeFilter.java:214) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1610) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:540) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:146) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:548) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:132) at org.eclipse.jetty.server.handler.ScopedHandler.nextHandle(ScopedHandler.java:257) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:1701) at org.eclipse.jetty.server.handler.ScopedHandler.nextHandle(ScopedHandler.java:255) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1345) at org.eclipse.jetty.server.handler.ScopedHandler.nextScope(ScopedHandler.java:203) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:480) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:1668) at org.eclipse.jetty.server.handler.ScopedHandler.nextScope(ScopedHandler.java:201) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1247) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:144) at org.eclipse.jetty.server.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:220) at org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:126) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:132) at org.eclipse.jetty.server.Server.handle(Server.java:502) at org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:370) at org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:267) at org.eclipse.jetty.io.AbstractConnection$ReadCallback.succeeded(AbstractConnection.java:305) at org.eclipse.jetty.io.FillInterest.fillable(FillInterest.java:103) at org.eclipse.jetty.io.ChannelEndPoint$2.run(ChannelEndPoint.java:117) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:765) at org.eclipse.jetty.util.thread.QueuedThreadPool$2.run(QueuedThreadPool.java:683) at java.base/java.lang.Thread.run(Thread.java:834)```

Hello all, while studying the Indy project I wondered if there is some kind of verifiable encryption implemented or if there are plans to implement it? So that for instance it would be possible for a prover to encrypt an identifying attribute from a credential in form of ZKP under the usage of a public key from a third party, so that this third party could decrypt the attribute in case of (proven) misbehaviour by the prover and identify him. Thank you!

swcurran (Thu, 08 Apr 2021 14:21:32 GMT):
At this point -- no plans for that. The prover can put self-asserted claims into a presentation, so in theory, I think that could work.

CryptoMuck (Thu, 08 Apr 2021 16:10:06 GMT):
Thank you very much. Are accepted proofs currently stored by the verifier in some form?

swcurran (Thu, 08 Apr 2021 18:22:53 GMT):
That's up to the verifier -- and the regulations under which they operate. Minimizing what the verifier holds can reduce their liability.

deas (Tue, 20 Apr 2021 12:44:46 GMT):
@waqaswahid1 I'm not an Indy expert, but I'm pretty sure that's not really what Indy is for. The beauty of Indy is that none of the private information is stored on chain; all of the private data moves between (Aries) agents in an encrypted peer-to-peer fashion following the DIDcomm protocols. All that's stored on chain is the sets of the definitions and public identities needed to enable the verifiability of proof presentations made in those subsequent peer to peer transactions. Out of curiosity, what would be the goal of making user data into NFTs?

waqaswahid1 (Fri, 23 Apr 2021 10:01:43 GMT):
[ ](https://chat.hyperledger.org/channel/indy?msg=S9vha3tSfoXbxZCiL) goal of making user data into NFTs is that user have the power to sell their personal data as an NFT to the companies.

swcurran (Mon, 10 May 2021 17:52:36 GMT):
The following was posted by the W3C DID Working Group. Does anyone (e.g. @brentzundel @peacekeeper @drummondreed ) exactly what is needed here? I tried to understand it, but it is not obvious to me what is supposed to be in the DID Method document, and what testing is done. ``` The W3C DID Working Group achieved another milestone last week; all tests for the specification are now complete. This means that we are ready for DID Method implementers to submit their DID Method implementations for conformance testing against the specification. The deadline for submitting DID Method implementations is in two weeks (by May 25th, 2021). The instructions on how to submit a DID Method implementation can be found here: https://github.com/w3c/did-test-suite/#adding-your-did-implementation If you are a DID Method implementer, please get your DID Method implementations submitted in the next two weeks. ```

Hello, is there any way with which we can get the private key associated with a DID in Indy. indy_create_and_store_my_did Function creates and stored the keys in the wallet and with KeyForDidAsync function we can get the verification key for the specified DID but this does not return the private key. so is it possible to Fetch the private key associated with the DID?

swcurran (Fri, 14 May 2021 15:10:05 GMT):
In Indy, use of the private key is embedded within Indy library calls, and the private key does not get exposed outside of those calls. I think there is even code that clears the memory where the private key was used to prevent it getting out. So, the basic answer is -- you can't. It's stored in encrypted storage, accessed by the routines that need to use it, and unavailable anywhere else.

sauveergoel (Tue, 25 May 2021 18:13:18 GMT):
why is there three revocations IDs for one credential definition?

swcurran (Tue, 25 May 2021 18:17:53 GMT):
Not sure what you mean by 3. There are two objects -- RevReg_Def and RevReg_Entry. The RevReg_Def is the metadata about the RevReg -- size, use type, ID, etc. RevReg_Entry -- are the updates to the RevReg as credentials are revoked -- the list of index values in the tails file that are revoked and the new accumulator for the entry.

sauveergoel (Tue, 25 May 2021 19:00:57 GMT):
when i am creating a revocation reg for a given cred def, it is producing 3 different rev reg ids

swcurran (Tue, 25 May 2021 19:01:03 GMT):
Is that using ACA-Py?

sauveergoel (Tue, 25 May 2021 19:01:06 GMT):
yes

sauveergoel (Tue, 25 May 2021 19:01:06 GMT):
yes, it uses ACA-Py

sauveergoel (Tue, 25 May 2021 19:03:42 GMT):
the interesting fact is that when I created the rev reg id it gave me a different id and when I issued a credential, it attached the an other id, both were out of the three displayed, but the point is how to identify which id was used in the credential as the issue credential outputs don't carry rev reg info

sauveergoel (Tue, 25 May 2021 19:04:40 GMT):
I am using the bcgov indy-tails-server as well

swcurran (Tue, 25 May 2021 19:04:56 GMT):
I'm not sure about the three, but ACA-Py creates an extra RevReg so that there is never a need to stop issuing to create a RevReg (which can take awhile). When ACA-Py includes revocation on a Cred Def, it automatically creates two registries. Then it activates one, and uses it until it is all used up. When the first is full, it switches to the second one, and makes a third one in the background. That continues as needed. An issue is never delayed to make a RevReg.

swcurran (Tue, 25 May 2021 19:05:26 GMT):
So, it's not an Indy thing, it's done at the ACA-Py level.

sauveergoel (Tue, 25 May 2021 19:06:23 GMT):
ohh ok, but then how do we know which one has been used for which cred, when we are an endorser

swcurran (Tue, 25 May 2021 19:07:34 GMT):
When issuing, the "issue credential" process should be returning the id of the credential and it's revreg -- you have to know both to revoke. As well, if you keep the credential exchange record around in the issuer, both pieces of data are in that, and I believe (could be wrong...) that you can supply that when revoking, and the data will be automagically pulled from that record to do the revocation.

swcurran (Tue, 25 May 2021 19:08:26 GMT):
I'm confused on the three IDs that you first had (unless you have done a bunch of issuing).

sauveergoel (Tue, 25 May 2021 19:08:37 GMT):
thats my whole issue, `issue-credential` endpooints are not giving me the rev_reg_id back

swcurran (Tue, 25 May 2021 19:09:39 GMT):
Hmmm.... need people with more knowledge here -- hands on in the code. @esune , could you please weigh in here?

this is the output of the /issue-credential/send API

sauveergoel (Tue, 25 May 2021 19:14:33 GMT):
it doesnot provide with rev_reg_id

swcurran (Tue, 25 May 2021 20:56:39 GMT):
Looks like it is still in the "Offer_sent" state -- which makes sense for the response to the API call -- it's an asynch operation to issue a credential. There should be a webhook come back to the controller when the credential itself has been issued. Also, you can query the credential exchange records and then look at the one for the issuance (assuming it has not been deleted).

esune (Wed, 26 May 2021 15:50:52 GMT):
@sauveergoel what version oaf aca-py are you using?

esune (Wed, 26 May 2021 15:50:52 GMT):
@sauveergoel what version of aca-py are you using?

esune (Wed, 26 May 2021 15:52:42 GMT):
As @swcurran stated, normally you would get `revocation_id` and `revoc_reg_id` as part of the response. Not sure whether they will show up if the state is prior to `issued`, as they might not have been written yet (I am not sure about this, but it is possible).

esune (Wed, 26 May 2021 15:54:05 GMT):
I would first make sure you can complete the flow and reach the `credential_issued` state on the credential exchange, and dig deeper afterwards.

swcurran (Sun, 30 May 2021 20:59:32 GMT):
FYI - Arnaud (Chair of the Hyperledger TSC) requested a "top story" about each Hyperledger project. I've sent this in for Indy: ``` The top story in the Hyperledger Indy community this year has been the deployment of new public instances of Indy. While the most active and best known instance of Indy, Sovrin's Mainnet, continues to operate smoothly, a new global ledger was deployed by Indicio.tech, and the IDUnion group deployed their network in the European Union. The expansion of networks has triggered efforts to create a new DID Method for Indy (called "did:indy") to enable resolving Indy identifiers across all public Indy networks. ``` Feel free to provide feedback -- we can adjust as needed before the Hyperledger Global Forum.

Not that I'm aware of. There many ledgers that store DIDs (90-odd last check?), and many Indy ledger instances. But no ledgers that store the same objects as Indy, but using a different underlying blockchain.

Hi all, I have a question regarding credential unlinkability. Based on the contents of a proof, a verifier cannot track which credentials are used to create the proof, I understand that. But if a prover wants to present a proof unlinkably multiple times to the same verifier, then it has to establish a new connection with the verifier for each presentation, correct? And I assume that on network level it must also be ensured that the individual presentations cannot be linked to each other (e.g. by changing IPs of the prover). Have I got all this right?

brentzundel (Wed, 02 Jun 2021 17:00:16 GMT):
Indy relies on state proofs for verification of read requests. This allows (currently) a read transaction to be answered by a single validator node, rather than requiring the read request to go through multiple validators. The same proof would allow for an observer node to be trusted.

swcurran (Thu, 03 Jun 2021 16:39:34 GMT):
A little more detail -- to make sure that the transaction is valid, a client could query each validator node, compare the answers and decide if it is correct. The state proof is signed by multiple validators (I believe (T - 1)/3 nodes where T is the total number of nodes) so that a client only has to ask one validator node, get back the state proof and verifiy it.

swcurran (Thu, 03 Jun 2021 16:49:21 GMT):
There are several things that are not quite right here. From the proof, the verifier can tell what credentials the claims come from -- they have to know that to know who issued the credential and to verify the signatures on the data. `But if a prover (AMA) wants to present a proof unlinkably multiple times to the same verifier (ACA Py), then it has to establish a new connection with the verifier for each presentation, correct?` That's correct -- a person/entity could do that. Would be like signing up for a website using different email addresses. Linking via IP address might be possible - depends on how the message travelled from prover to verifier. With DIDComm, that could be multiple hops.

Hi, I've been working with indy for a while and I notice kind of inconsistency in pool genesis format. I mean that, some versions have the pool_genesis content in where services port numbering is defined as string and others as integer. The problem arises when you try to load one of those files to connect to the pool, because you will get a common invalid state error message. For example: the sandox pool genesis (https://raw.githubusercontent.com/sovrin-foundation/sovrin/stable/sovrin/pool_transactions_sandbox_genesis) has ports encoded as string, while built-in development pool included in indy-sdk repo, has them defined as integers (https://github.com/hyperledger/indy-sdk/blob/master/samples/nodejs/src/util.js). So, what is the correct data type for this field?

swcurran (Fri, 04 Jun 2021 15:06:56 GMT):

lynn.bendixsen (Fri, 04 Jun 2021 17:04:51 GMT):
All of the public networks that I have created genesis files for use strings for the ports, so I would assume that strings is the correct format. To create my genesis files I use: https://github.com/sovrin-foundation/steward-tools/tree/master/create_genesis and I have some step-by-step instructions to help with running that script: https://docs.google.com/document/d/1HXG6WOl_3K7k63CNdYEiTk1Y3eMiwLuhr5uTHg3RaoY

swcurran (Fri, 04 Jun 2021 18:11:39 GMT):
Presumably indy-sdk accepts both. @andrew.whitehead -- can you confirm that indy-vdr does as well?

andrew.whitehead (Fri, 04 Jun 2021 18:57:27 GMT):
It looks like client_port and node_port should both accept a string or number

sergio.anguita (Mon, 07 Jun 2021 08:35:19 GMT):
Im working on type safe application and needed to know the correct data type, just to avoid extra code for handling both datatypes. For what you said, using String is the most desirable way, am I right?

Yes, in fact we've integrated with keycloak (on openshift) so you can authenticate with a verifiable credential

ianco (Tue, 08 Jun 2021 19:07:06 GMT):
SOVRIN is an implementation of a public Indy network

Hi, is anybody able to build the Postgres wallet storage plug-in on windows? whenever i try to build, it always gives this error: error[E0463]: can't find crate for vcpkg. https://github.com/hyperledger/indy-sdk/issues/2248

can we export a postgreSQL wallet?

this was solved following your advice, thansk

ianco (Fri, 11 Jun 2021 21:18:55 GMT):
Yes you can use the indy cli to export the wallet. (All the wallets are compatible, so you can export from postgres and import into sqlite or the other way around)

As I asked in #aries, can Indy manage something like "data DID" (or document DID)? I heard that ACA-py can't handle such concepts, is that also the case in Indy? In this case, "manage" means issuing a DID Document with data as the subject, controller as the data manager (person), etc. Some people have mentioned using Indy as a document management system. Have you done anything like this?

Shweta1 (Tue, 15 Jun 2021 10:56:28 GMT):
shweta

swcurran (Tue, 15 Jun 2021 13:41:06 GMT):
The ACA-Py answer was based on capabilities of Indy -- not for Aries/ACA-Py per se. Indy is only used for storing specific data related to the issuing of verifiable credentials. It is not for storing arbitrary documents, and does not support doing so. Currently, the DIDDoc returned from resolving an Indy DID is constrained to a very limited format.

Hi @swcurran Is there any architecture-vs-repository map to know everey development performed under Indy+Aries ecosystem?

swcurran (Wed, 23 Jun 2021 14:38:05 GMT):
Not that I know, but that doesn't sound too hard to create. Maintaining may be harder, but it's pretty known right now. Do you have an example of what you are thinking of from another ecosystem?

jacobsaur (Thu, 24 Jun 2021 00:08:12 GMT):
Hi all, I had a question about the quintessential zero-knowledge proof example of Alice proving that she is over 18 without revealing her DOB - given that current Indy predicates only work on int32s, what is the best way to represent dates in a credential such that they work for predicate proofs? I had one idea: at first I was trying to go with an approach of number of days since a certain epoch and being able to use common datetime functions to do the calculations, but it seemed rather complicated and there were a lot of subtle issues around timezones, leap seconds, which epoch to choose, etc. The approach I would like to propose is to apply simple modular arithmetic to map a date to an int of the form YYYYMMDD. This would allow easy conversion to int and back to date without any confusion that would result from using time libraries. The only gotchas I can see are that you couldn't represent dates before AD (which seems ok, or they could be negative which also seems ok), and that you'd need to have some error handling if somehow a credential was ever submitted with an invalid mapping eg 20201332 (13th month, 32nd day, etc) - although some error handling on credential issuing should address that. To construct the proof the verifier would just convert today's date minus 18 years to int form, and then check that the int-date DOB on the credential is < that. What do people think? Ideally I'd like to use a standard date convention so if there's not already one, I could add a proposal to https://github.com/hyperledger/aries-rfcs/blob/master/concepts/0074-didcomm-best-practices/README.md#date-time-conventions (or create a new RFC)

(And I should specify that 32 bit unixtime wouldn't work, as we want to include dates outside of 1901-2038)

sergio.anguita (Thu, 24 Jun 2021 09:47:58 GMT):
dates can also considered as numeric values using epoch format, which is more standarized way to figure out if a value is bigger or less than certain threshold. In that way, the epoch is truncated to int32 size to make the calculations. Does this fit for your needs?

i think you can still apply the unix with a offset substraction

sergio.anguita (Thu, 24 Jun 2021 09:49:45 GMT):
i think you can still apply the unix format with a 69 year (1970-1901) offset implementation

jacobsaur (Thu, 24 Jun 2021 16:45:32 GMT):
I believe the epoch format for unix timestamps can only cover dates between 1901-2038 (unless you're referring to another format), and we need to be able to handle dates outside that range (eg 30-year mortgages in the future, land titles in the past, etc).

swcurran (Thu, 24 Jun 2021 17:27:13 GMT):
I would love to see this. A couple of interesting challenges to throw into this: - It would be nice to be able to do this via a convention so that it can be used with minimal/no changes to Indy AnonCreds and the indy-sdk. - If you switch to epoch for the raw data, the format becomes ugly for display, such as in the wallet. It could lead to needing both an epoch date and a "human" date attribute. Would it work to have a convention of the field name and data format? For example, the name of the attribute must end in "DT" and the data element must be an ISO date format. Alternatively, perhaps it is sufficient that the string format being an ISO Date is sufficient. If you do that, then the encoded value can be an integer date, and the proof request predicate could assume it is a date. The encoding would then have to be formalized in an RFC, so that all participants were aware of it.

swcurran (Thu, 24 Jun 2021 17:29:28 GMT):
FYI -- here is the current definition of how to encode data in Indy credentials: https://github.com/hyperledger/aries-rfcs/blob/5fdf3bbdc31881fd18162f7f2051b139537942a0/features/0037-present-proof/README.md#verifying-claims-of-indy-based-verifiable-credentials

swcurran (Thu, 24 Jun 2021 17:30:16 GMT):
This would extend that to include some "format-sniffing" to decide if something is a date and then encoding it as appropriate.

jacobsaur (Thu, 24 Jun 2021 21:57:32 GMT):
Would the approach I suggested of mapping to an int in the form YYYYMMDD address most of these issues - ie it doesn't require changes to Indy AnonCreds and it's more or less human readable? Granted some UIs will still probably want to format it into a date format appropriate for their locale but at least you can tell what date it is by looking at it.

swcurran (Thu, 24 Jun 2021 22:20:56 GMT):
Doh...I misread what you wrote and was making it more complicated. That's a great idea and it does solve the human readable problem -- nice! Nevermind what I said. This is excellent and solves the issue very nicely! `#respect` OK -- lets push it.

gut (Fri, 25 Jun 2021 13:08:42 GMT):
No, I don't have any examples. Sorry for that. In some way, it is already done in each repo references. I'll try to gather it myself and share it as it could be helpful for newcomers.

Hi everyone, I have a question about indy node performance. When we perform a load test with indy java wrapper, the tps values we get are very low (for example, the tps value for nym request is around 50-60) and when we monitor,we saw that java threads are waiting on submit request step. Does anyone have a similar load test and get different values? Or if you can get much higher tps values, what would you suggest to check? Not only write request but also read request is giving similar tps results. We made our test in our private network ( which 4 nodes on same machine different docker containers and machine resources 40 GB ram,30 CPU, 105 GB storage.)

I was thinking it should go in either or both of https://github.com/hyperledger/aries-rfcs/tree/master/concepts/0441-present-proof-best-practices and this https://github.com/hyperledger/aries-rfcs/tree/master/features/0592-indy-attachments In a quick scan of 0592, I don't see the "verifying claims" section that was in 0037 (link from my earlier comment), so I think we should add that in, and include this idea there and in the examples. As well, we need the caveat of this not handling time zones and all that stuff, so the test is accurate to +/- 24 hours. I think we should verify the process and document it so that people have a clear example of "To prove a person is over 21, do the following" covering the attribute in the schema, the credential data and the proof request. The RFC you mentioned is a general one about DIDComm messages, not about VCs, so I recommend NOT adding it there. We need to focus on clarifying the handling of this for Indy AnonCreds.

jacobsaur (Mon, 28 Jun 2021 19:41:09 GMT):

Hi, It's possible to query from indy-cli for all schemas in a DOMAIN ledger? like in VON Ledger Browser filtering by txn_type=101. Many thanks.

No. There are no query mechanisms on Indy. VON Ledger browser and IndyScan query one by one through all the ledger objects, creates a database and use that to do queries like the one you want to do.

Sorry for newb question. I have stucked here for days. I even tried to search on past messages but I still unable to get indy-cli working on MacOS Big Sur. I am using .zshrc to set up the environment path but zsh still returns command not found. Here's how my .zshrc looks like `export LIBRARY_PATH=~/Users/capuchin/SDK/indy/libindy_1.16.0/lib/ export LD_LIBRARY_PATH=~/Users/capuchin/SDK/indy/libindy_1.16.0/lib/ export LIBINDY_DIR=~/Users/capuchin/SDK/indy/libindy_1.16.0/lib/` Can someone point to me what did I do wrong? and also runnin indy-cli executable file returns `capuchin@macintosh ~ % /Users/capuchin/SDK/indy/indy-cli ; exit; dyld: Library not loaded: /Users/jenkins/workspace/indy-sdk_indy-sdk-cd_rc/libindy/target/release/deps/libindy.dylib Referenced from: /Users/capuchin/SDK/indy/indy-cli Reason: image not found zsh: abort /Users/capuchin/SDK/indy/indy-cli`

Looks like you're using absolute paths, so you shouldn't include the `~` prefix

ianco (Wed, 07 Jul 2021 14:07:34 GMT):
... also rather than updating your `PATH` env variables try creating links to the `/usr/local/lib` directory (which is searched by default)

ianco (Wed, 07 Jul 2021 14:08:39 GMT):
e.g. `ln -s /Users/capuchin/SDK/indy/libindy_1.16.0/lib/somefile.dylib /usr/local/lib/somefile.dylib`

Hey all, I am trying to locally run von network and aries cloud agents. So to begin with, I am using sovrin network - stagging network genesis block to start the von network locally. Now when I start the aries-cloud-agent with the local LEDGER_URL and it gives me TAA error while creating schema. The did is registered on the sovrin staging network using `https://selfserve.sovrin.org/nym`. Not sure why I am still facing the TAA error since von network code was recently updated to incorporate those changes. Anyone has any idea about this?

WadeBarnes (Tue, 13 Jul 2021 12:05:15 GMT):
It sounds like you're connecting to Sovrin StagingNet and not a `von-network` ledger instance. From what I can gather you're setting up `von-network` as a ledger browser for Sovrin StagingNet.

WadeBarnes (Tue, 13 Jul 2021 12:06:23 GMT):
What's the error you are getting regarding the TAA? When a TAA is enforced on a network you need to accept the agreement using one of the accepted options.

domwoe (Wed, 14 Jul 2021 09:56:31 GMT):
For indy credentials not really. Indy creds are just lists of attributes. So as soon as you want to define an array with an unspecified size (as your example suggests) you have a problem.

PatrickHerbke-TUBerlin (Wed, 14 Jul 2021 10:00:51 GMT):
is there a more detailed documentation somewhere than https://hyperledger-indy.readthedocs.io/projects/sdk/en/latest/docs/how-tos/save-schema-and-cred-def/README.html? Would our approach (array lists) generally not work or can code passages be adapted to implement this?

PatrickHerbke-TUBerlin (Wed, 14 Jul 2021 10:04:03 GMT):
The current schema restrictions wouldn't allow any more complex certification, such as high school diploma (Abiturzeugnis). We don't want to store just signed pdf files in our wallet solution...do you have a tip, which solutions would offer themselves for it?

domwoe (Wed, 14 Jul 2021 10:09:38 GMT):
Currently you could either (1) Prepare a schema/creddef that supports a fixed number of arrays items and make them explicit attributes0.degree.type ..., but this makes proof requests pretty ugly. (2) have the whole attributes block as one stringified attribute, but then you have to disclose the whole block

domwoe (Wed, 14 Jul 2021 10:10:36 GMT):
The main issue is that a credential definition includes cryptographic matterial per attribute. Hence, the number of attributes is fixed

domwoe (Wed, 14 Jul 2021 10:11:32 GMT):
There was work in Rich Schemas, but it's more likely that we switch to W3C Credentials with BBS+ Signatures

domwoe (Wed, 14 Jul 2021 10:11:32 GMT):
There was work on Rich Schemas, but it's more likely that the community switches to W3C Credentials with BBS+ Signatures to support such use cases

swcurran (Wed, 14 Jul 2021 10:17:09 GMT):
Note that such use cases with BBS+ are going to "fun". While you can have an arbitrary length array, for selective disclosure, all of the attributes become a list, and you pick the elements of the list to disclose. Thus, to expose an entry (set of values) in the array, you will have to determine the indices in the list for those items. That said, a user interface can be constructed for the Holder to make the selection of the values in they array they want to disclose and then have the code calculate the list indices needed.

Hello! two quick questions: Are the Hyperledger Indy's credentials actually Smart Contracts, or does Indy actually use Smart Contracts?

swcurran (Wed, 14 Jul 2021 18:58:49 GMT):
No and No. Indy credentials do not go on a ledger. Only public keys for signing / verifying credentials, credential schema metadata, and revocation data go on the ledger.

Lucampelli (Wed, 14 Jul 2021 19:01:20 GMT):
Nice, thank you! One last question: In a setting where a university needs a credential in order to be valid for issuing a diploma. If the university's credencial were to be revoked, and the university ceased function, how to check if the university was "valid" by the time the diploma was sent, if it is needed to obtain the proof from the university in order to check that?

Lucampelli (Wed, 14 Jul 2021 19:02:22 GMT):
I'd say maybe the university generates and sends the proof, together with the diploma credencial... what do you think?

Lucampelli (Wed, 14 Jul 2021 19:03:01 GMT):
This way the student would be able to send that proof with the diploma proof, and someone would be able to check both right?

There has been some talk of that -- being able to include a proof within a credential. The RFC 104 chained credential talks about that use case. https://github.com/hyperledger/aries-rfcs/tree/master/concepts/0104-chained-credentials That said, I'm not aware of an implementation of this. Would love to see it as it could add a lot of interesting capabilities, including the one you mention.

We are sucessfully able to set up a static indy pool, but we want to add nodes dynamically as given in this document. But, if our node is on a different EC2 instance, how can we give the access of genesis file as it doesn't exist on this new instance?

The genesis file is a static document once established, and so can be put in an accessible place. For example, the Sovrin network genesis files are on GitHub.

Hello Team, We are developing edge agent for android. We are using libindy library for android taken from " https://repo.sovrin.org/android/libindy/stable/1.16.0/". When we try to store the credentials using indy_prover_store_credential, we see the following error- "indyorg.hyperledger.indy.sdk.InvalidStructureException: A value being processed is not valid." Please note that we have ensured the following: 1. we are passing valid JSON string values for all the input params. For "rev_reg_def_json" we passed null. 2. ensured the JSON strings carry the value null instead of "null", wherever applicable. Any pointers to how we can find out which param may be causing the issue? The library does not specify that in the error. We tried to build the libindy for android by adding few logs. But we could not successfully compile it. The 'cargo build' is successful but the 'build-libindy-android.sh' is failing with error - "can't open file 'build/tools/make_standalone_toolchain.py' :[Errno 2] No such file or directory?" We are building on ubuntu 20.0.4. Did anyone face this issue or knows what could be the issue?

WadeBarnes (Tue, 20 Jul 2021 12:29:23 GMT):
A few things to look at: - Indy-node uses ports 9700-9799. I see 8701 and 8702 in your screenshot. - There is a distinct difference between internal and external client and node IP:Port addresses, especially on AWS. When initializing the node you need to use the internal addresses and ports. When registering the node on the network with `ledger node` you need to use external (publicly accessible) addresses. - The genesis file must be constructed with publicly accessible addresses. - After that you need to make sure you have your internal and external addresses mapped correctly.

MikeSmith (Thu, 22 Jul 2021 17:21:25 GMT):
Hello Everyone, I am a beginner in Hyperledger Indy and trying to understand the basics. There is one question that I am not able to relate or understand. What is the purpose of adding a node to an indy pool? Does the node gets added as validator node and become a part of consensus? If so what is the reward of becoming a validator node? Could anyone please guide me here?

MikeSmith (Thu, 22 Jul 2021 17:25:45 GMT):
Hello Everyone, I was trying to setup Indy node and as per the documentation I found only Ubuntu 16 is preferred. Is there any way to make the setup on Ubuntu 20?

lynn.bendixsen (Thu, 22 Jul 2021 17:39:04 GMT):
Adding nodes to an Indy pool helps with consensus as every node currently added becomes a participator in consensus. Because of the BFT algorithm that Indy uses for consensus, the more nodes that are part of the pool, the more robust, or stable the network is (or more tolerant of nodes going down or unavailable). The best benefit of running a node on a public Indy network is the good feeling you get about donating to a great cause! Think of the prestige and the marketing opportunities! Participating also makes the network diverse, decentralized and viable, so if the product you are working on needs a network, it pays to support at least your favorite one, and maybe more than one, as we head into an era of multi-network compatibility and usage. Node Operators (Stewards) do not have any special write privileges on the major public networks at this time, they simply manage their node. Some networks might return some of the eventual profits of the network to Node Operators, but even then it is unlikely that it will do much more than cover costs IMO.

Hi all! I would need some help with running and integrating the indy-node or sovrin in a real project. I am working on it almost for a week now, but several packages and links are broken or deprecated, even the getting started docker file from (https://github.com/hyperledger/indy-sdk/blob/master/docs/getting-started/run-getting-started.md) through the Indi-CLI eventually I managed to generate an own DID, but not even with that I was able to connect to the created sandbox in the end, only to a sandboxes, which were in the list already. I guess there was some issue with the IP addresses. Please, I am a junior software developer, and not a big master of computer science. However it would be really important to me, to integrate some way the DID based connection in our project, but need some help or further explanation, from someone who already did that.

Chances are you are looking to create an agent -- a component to use verifiable credentials -- issue, hold or verify them. Assuming so, you should be looking at Aries, not Indy. Aries enable you to build agents to exchange verifiable credentials. Take a look at the getting started part of the https://github.com/hyperledger/aries-cloudagent-python README. We've put together a course on becoming an Aries developer on edX -- https://www.edx.org/course/becoming-a-hyperledger-aries-developer

gaberasturi (Wed, 28 Jul 2021 07:45:48 GMT):
Hello, I have one doubt about log levels in VON-NETWORK. At docker-compose level we have two log related environment variables. - LOG_LEVEL=${LOG_LEVEL} - RUST_LOG=${RUST_LOG} I suppose the levels are: INFO, WARNING, ERROR, DEBUG, TRACE But how can I enable diferents levels? or how do we need to config then? i mean how is the "string" needed to enable f.e debug level. Its posible to have granularity of logs only enabling at some of them Indy, zqm, cripto,...? Following the next link https://jira.hyperledger.org/browse/INDY-1104 We are able to enable debug on each node editing `/etc/indy/indy_config.py` and adding `logLevel = 0` but want to know if there is an easier way Thanks in advanced.

sergio.anguita (Wed, 28 Jul 2021 11:23:56 GMT):
@bt333 have you tried something like https://indyscan.io/home/SOVRIN_MAINNET?

sergio.anguita (Wed, 28 Jul 2021 11:24:25 GMT):
its opensourced at github (https://github.com/Patrik-Stas/indyscan) - ISC LICENSE

WadeBarnes (Wed, 28 Jul 2021 11:40:58 GMT):
Could you please open a new issue on `von-network` for this please; https://github.com/bcgov/von-network/issues. We'll be happy to answer your questions there.

WadeBarnes (Wed, 28 Jul 2021 11:46:12 GMT):
Have you looked at [von-network](https://github.com/bcgov/von-network)? It's a indy-node based ledger designed for use during local development. It has a ledger browser built in so your can review the transactions on the ledger.

WadeBarnes (Wed, 28 Jul 2021 11:47:04 GMT):
Example hosted instance; http://test.bcovrin.vonx.io/

WadeBarnes (Wed, 28 Jul 2021 11:50:39 GMT):
When running in AWS it's important the nodes are initialized with their internal IP addresses, while when registered with the network you need to use the public IP address so nodes are able to reach each other.

WadeBarnes (Wed, 28 Jul 2021 11:53:08 GMT):
You can use `nc` to test the connection from each node to the other nodes. example `nc -vz `

WadeBarnes (Wed, 28 Jul 2021 11:55:58 GMT):
Use cases are somewhat endless. Any use case that can benefit from verifiable credentials: - Identity - Licensing - Proof of origin - Authentication and Authorization - etc.

WadeBarnes (Wed, 28 Jul 2021 11:57:16 GMT):
Are you specifically looking for case studies?

Shweta1 (Wed, 28 Jul 2021 13:12:09 GMT):
Thanks Wade,it is connected.but how pool_transactions_gensis will be update.this file have only first four nodes

WadeBarnes (Wed, 28 Jul 2021 13:15:12 GMT):
The `pool_transactions_gensis` file will only contain what is originally (manually) written into it, it does not get updated automatically as new nodes are added to the pool. It is only used to bootstrap connections to the ledger. Once a connection is made a node or client can read to pool ledger to get the full list and state of the nodes in the pool.

WadeBarnes (Wed, 28 Jul 2021 13:22:15 GMT):
For example, the gensis file for Sovrin BuilderNet only contains four entries; https://raw.githubusercontent.com/sovrin-foundation/sovrin/stable/sovrin/pool_transactions_builder_genesis

WadeBarnes (Wed, 28 Jul 2021 13:22:15 GMT):
For example, the gensis file for Sovrin BuilderNet only contains four entries; https://raw.githubusercontent.com/sovrin-foundation/sovrin/stable/sovrin/pool_transactions_builder_genesis. While the network has 19 nodes currently.

Shweta1 (Wed, 28 Jul 2021 13:22:46 GMT):
Thanks WadeBarnes!! so this pool_transactions_genesis will remain same.When ever i am initializing new node,this pool transaction file should be provided first.

Thanks, it really helped

bt333 (Wed, 28 Jul 2021 17:15:09 GMT):
Hello Team, Can anyone please help me with N = 3f+1 , How does it actually works? Is it a possibility formula if there is 1 malicious node then there should be a total 4 nodes to handle it? I am trying to understand the process if a pool gets created of 4 loyal nodes and then 4 malicious nodes join the pool. How it can be prevented?

swcurran (Wed, 28 Jul 2021 18:12:57 GMT):
It means if you have N nodes, you can handle up to f failures, where f = round((N - 1)/3). So if you have a 25 node network, you can sustain up to f = 8 failures. Likewise, if you have a 4 node network, you can sustain f =1 failures. The balance is that the more nodes, the slower the consensus, so you have to balance speed with network resiliency. A failure is either a node outage or a detected malicious node.

WadeBarnes (Mon, 02 Aug 2021 13:05:48 GMT):
When changing an existing node's configuration you don't specify all of the parameters, only some. For example removing a node from the network would be `ledger node target= alias= services=`. `arget= alias=` always required.

Is there a particular reason you are running it directly on your machine rather than running it in the docker environment; `./manage build`, `./manage start`? Using the docker environment contains all of the dependencies.

WadeBarnes (Wed, 04 Aug 2021 13:09:36 GMT):
If you are just trying to connect the ledger browser to another network , you are better off doing it this way; https://github.com/bcgov/von-network#running-the-web-server-in-docker-against-another-ledger

SwapnaliDive (Wed, 04 Aug 2021 13:14:12 GMT):
Thanks for your reply. We are trying to use von network web app where we can review the transctions occuring on the ledger. We have set up our indy network and now we want a monitoring service. We are trying to run von network locally so that we can pass our genesis file. But during the setup itself we are getting above errors.

WadeBarnes (Wed, 04 Aug 2021 13:57:11 GMT):
It might just be easier to make your genesis file web accessible so `von-network` can download it. Or, update the code and docker environment to be able to accept (mount) a genesis file. Then you could contribute that back to the project for others to use.

WadeBarnes (Wed, 04 Aug 2021 13:58:11 GMT):
For Network/Node monitoring there is this project; https://github.com/hyperledger/indy-node-monitor

Could someone confirm? Is there anything else required to make genesis web accessible?

Hello Team, Can someone help me to understand this? When we create a pool so we start with few number of nodes those come inside the pool genesis file. Are those nodes steward or trustee ? If these are not trustee then where does trustee exist? Also, what if my all pool *genesis * nodes are down then what will be the impact?

I Hello everyone, I am working on indy node backup.i am using /var/lib/indy/sandbox/Node1/data/... to restore data. 4 nodes are running on host1.Again I am trying to run these 4 nodes on host2.is it possible to restore all indy nodes data from host1 machine to host2.

WadeBarnes (Tue, 10 Aug 2021 13:45:39 GMT):
Nodes only have a single role (at the moment), they are validators. The role of Steward and Trustee is for DIDs. A Steward DID has the permissions to manage their node's configuration on the ledger, while a Trustee is able to perform more privileged operations. The basic roles and permissions can be found here; https://github.com/hyperledger/indy-node/blob/master/docs/source/auth_rules.md

WadeBarnes (Tue, 10 Aug 2021 13:45:59 GMT):
Auth rules can be customized for a given network.

Hi all, I am trying to add a new kind of transaction or modify NYM transactions to include some additional information. Can anyone point me to the relevant places in the code to do that? I am trying to understand indy-node and indy-plenum codebases for a couple of weeks. Looks like I need to add the new type of transaction to plenum. Do I need to make changes to the indy-sdk also?

swcurran (Wed, 11 Aug 2021 18:14:27 GMT):
Not sure where in the indy-node/plenum code. If you are modifying the NYM transaction, I think (not certain) that you only have to change indy-node. If you are using indy-sdk to send transactions, then yes, you also have to update indy-sdk with the new information being sent.

If all pool genesis nodes are down, then any agent or entity that only has the genesis file will not be able to connect to the network.

lynn.bendixsen (Thu, 12 Aug 2021 14:42:43 GMT):
Hi @Amit18, At a somewhat high level, if only some of your Nodes crash, then the data directory on those Nodes will be automatically populated when you bring the Nodes back up. This is called "catchup", I think, and it happens on Node startup or when you first add a node to the network. If all nodes go down, then complications might arise that I am not 100% sure about. There are some checks that are performed based on information in the audit ledger. I am pretty sure that an identical copy of the Data directory could be restored to every node on the network and then it would work, but my information might be outdated. Try it out and let us know :)

lynn.bendixsen (Thu, 12 Aug 2021 14:50:57 GMT):
That's a tough one because not even the genesis files will work for getting connected to that network. Changing the IP addresses of all of your genesis file nodes, means that you need to create new genesis files to be able to connect. The Indy Blockchain architecture does not seem to mesh well with the scenario that you propose...

Amit18 (Thu, 12 Aug 2021 15:02:16 GMT):

lynn.bendixsen (Thu, 12 Aug 2021 15:11:19 GMT):
Updating the genesis file (changing it) is not allowed. It violates the blockchain "immutable ledgers" notion. The only way to update a genesis file is to extend it to be larger so that it includes the additional changes made , for example, to update the IP addresses while the ledger is live. The only other way to do what you are talking about is to reinstantiate the ledger, then replay all of the transactions that you want to have on your new ledger.

Ideally, the IP addresses where we are running the node shouldn't be stored in ledger and assuming them as part of configuration files. In hyperledger fabric we use alias names for peers and orderers. is there any notation that we can use in Indy node?

Transaction rejected occurs when there are not enough nodes in the pool that are in consensus. Without more details, it's difficult for me to tell what happened to the other nodes (for a 4 node network, you need 3 to be up and participating in consensus). Your log files might help you determine what has happened to the other nodes. /var/log/indy//.log

lynn.bendixsen (Thu, 12 Aug 2021 21:22:00 GMT):
None that I know of. Indy does not allow for anything like that, ,and I am not sure why, but it's probably for security reasons.

Hello Team, We are trying to migrate one node from one aws instance to another. We have total 5 nodes running when we are trying to migrate 5th node which is running at 5th instance to 6th instance then we are not getting success. Below are the steps that we are following : 1) At 5th instance we are shutting down our 5th node 2) At 6th instance we are copying pool_transactions_genesis and domain_transactions_genesis from 5th instance. 3) On 6th instance we are running -- -- sudo init_indy_node Node5 9711 9712 -- sudo start_indy_node Node5 9711 9712 -- Then from indy-cli, using node owner did we are adding Node5 ledger node target= client_port=9712 client_ip= alias=Node5 node_ip= node_port=9711 services=VALIDATOR blskey= blskey_pop= After following the above steps , other nodes able to find 5th node from new_ip but when we are starting 5th node from 6th instance it is not connecting with other nodes. Could anyone please verify the above steps and guide us ???

WadeBarnes (Fri, 13 Aug 2021 14:16:21 GMT):
When initializing the node on the new host, you need to include the random seed that was generated from the first time you ran the init_indy_node command on the previous host, otherwise a new random seed is generated and all of the keys will be different, so it will appear to the network as a new node with a duplicate name (alias).

WadeBarnes (Fri, 13 Aug 2021 14:16:57 GMT):
The format of the command you need to use is; `sudo -i -u indy init_indy_node `

WadeBarnes (Fri, 13 Aug 2021 14:18:10 GMT):
When you first ran the init command the output would have included a line like this: ``` Generating keys for random seed b'FA7b1cc42Da11B8F4BC83990cECF63aD' ```

WadeBarnes (Fri, 13 Aug 2021 14:19:06 GMT):
It's that seed (the value between the single quotes) you need when re-running the init on the new host.

WadeBarnes (Mon, 16 Aug 2021 12:28:59 GMT):
You need to update the genesis file manually.

bt333 (Mon, 16 Aug 2021 13:38:45 GMT):
Could you please confirm this? So, If there is a pool of 100 nodes where 10 are the founder nodes and one of founder node migrated to different IP which will lead to update the genesis file manually. After the manual updation of Genesis file all the remaining nodes will need to update their genesis file manually? They will have to follow pool connection process again? Does it mean that it is recommended that founder nodes should remain at same ip and port for forever?

swcurran (Mon, 16 Aug 2021 13:43:52 GMT):
Interesting. There is a plan to create `did:indy`, and one of the 2 major purposes for that effort is to do what you are doing. Here is the definition of what is planned: https://hackmd.io/@icZC4epNSnqBbYE0hJYseA/S1eUS2BQw I think the change is in indy-node only (on the ledger side), but am not certain. And there would be indy-sdk/indy-vdr changes on the client side to retrieve the data.

Would there be anyone so nicely to help me ?

WadeBarnes (Wed, 25 Aug 2021 13:11:11 GMT):
@huzhiyang, You may find it easier to get started with https://github.com/hyperledger/aries-cloudagent-python The tutorials and getting started guides are more up to date. It provides a layer of abstraction that hides many of the intricate complexities on Indy.

I think that is possible, but really everything would have to be the same, so it would probably be quite difficult to succeed. (Each node would have to restore their own original same keys, same IP's, same aliases, etc) I am not sure about the migrate, all of what I have worked with is multiple separately managed nodes for networks.

Hi, I'm trying to connect the indy sample to a production network, instead of the local docker indy pool. The network is set up and I can connect to it via the indy CLI, using the network's genesis file. But when I try to use that same genesis file to connect from my indy-sdk environment (which is local to my machine, same as the indy CLI) it times out (`UnhandledPromiseRejectionWarning: IndyError: PoolLedgerTimeout`). I think this could mean that the network is not configured to accept all the right traffic... but if that's the case how come my indy CLI from the same machine _can_ connect? Has anyone had this issue? Does anyone have an idea?
