Hi @all my name is Martin Wainstein, and I'll be chairing this SIG alongside Tom Baumann. I run the Yale Open Innovation Lab, and climate finance projects at the Digital Currency Initiative at the MIT Media Lab. We actively work on climate across the whole scope and have been working closely with Hyperledger in recent months. Will be updating the wiki and mailing list soon. Great to have this launched and looking forward to some great discussions happening here!

Can anyone remember who posted the whitepaper "A DID for Everything" in the Zoom chat on the 11th. I have just read through it. The idea that literally everyhting can have an ID and that the provenance of data can be verified transparently will be extremely important when accounting for actions on planetary scale. The way in which DADs are namespacible also present a lot of opportunities for standarisation. A standard for the way in which we identify data, data sources, data processors and curators within the context of climate change mitigation and adaptation could be something that this group can work on that can benefit a lot of the work many of us are already doing

ChristiaanPauw (Thu, 13 Feb 2020 11:11:03 GMT):
a lot of opportunities

ChristiaanPauw (Thu, 13 Feb 2020 11:11:15 GMT):
for standardisation

VipinB (Thu, 13 Feb 2020 13:34:56 GMT):
Zoom chat is great for certain things. In meetings, rocket chat is preferred over zoom chat because of greater transparency and persistence. Zoom chat is integrated and immediate, but disappears- can be recovered after the call, when recording-

jljordan_bcgov (Thu, 13 Feb 2020 19:09:49 GMT):
This is probably what you are talking about ... https://github.com/SmithSamuelM/Papers/blob/master/whitepapers/A_DID_for_everything.md

jljordan_bcgov (Thu, 13 Feb 2020 19:10:44 GMT):
I have some different views on this .. you might want to check out https://dev.w3.org/2008/video/mediaann/ReSpec.js/documentation.html

jljordan_bcgov (Thu, 13 Feb 2020 19:11:01 GMT):

ChristiaanPauw (Fri, 14 Feb 2020 08:20:38 GMT):
Thanks for the links. I still have to think through the implications of the distintion between public and privte DID in the context on climate change mitigation and adaptiation projects. I struggle to see the connection between ReSpec.js and DIDs / DADs - maybe you can elucidate

jljordan_bcgov (Sun, 16 Feb 2020 03:57:17 GMT):
you may want to look over the Trust over IP RFC in Hyperledger Aries ... https://github.com/hyperledger/aries-rfcs/tree/master/concepts/0289-toip-stack We see this as the emerging stack for trustworthy data exchange. I believe that the most important packaging of data will be in Layer 3 of the stack ... a key one being Verifiable Credentials (a W3C data format standard). These will be the things that allow us to create trustworthy representations of constructs like a GHG Emmission profile. This is what we can "count". Then we can construct accounting systems that are able to track these constructs. Quite analagous to money and accounting practices. DIDs will be a lower level construct that machines largely deal with. DIDs for public issuers and Peer DIDs to faciliate the DIDComm procotol at layer 2. Have a look and see what you think. Happy to answer questions.

jljordan_bcgov (Sun, 16 Feb 2020 03:58:32 GMT):

Hello all, my name is Peter Clarke, and I'll be chairing this SIG alongside Robin and Sherwood. I put together a blockchain startup about 5 years ago with alumni from LSE IDEAS at the London School of Economics called Affine. Our mission was to develop projects that would address global challenges by using emerging technologies. This started with Fabric v0.6 and connecting with central banks on 8 May 2016. Great to participate in CASIG and looking forward to serve the CASIG community! Peter

@VipinB Yes, there is more information on the securitisation network posted on the CASIG wiki in Draft Form. We will provide you with a link to V2. The structure is a hybrid multi-seller, 'cascading' or 'waterfall' variable note programme. This will start with a traditional warehousing line, This V2 will be posted to the CASIG group but I will ensure you are provided an extra link in the abundance of caution. ETA 12 hours. Thank you, Robert

robertjames77 (Wed, 24 Mar 2021 01:38:49 GMT):
@RobinKlemens Robin, thank you for your informative response. We had a team meeting this morning and elected not to upgrade the Securitisation Blockchain to 2.2.1

robertjames77 (Wed, 24 Mar 2021 01:43:32 GMT):
We are operating an IBM Cloud Blockchain network equivalent to HL Fabric V.1.4+

robertjames77 (Wed, 24 Mar 2021 01:49:37 GMT):
By 'participating organisations' I assume you mean collaborators rather than organisations org1 org2. The answer to the first question is we are not collaborating yet with another team or organisation. The second question - org1 and org2 orderer1 using Kafka and the application lawyer is 'Securitizaton' .

RobinKlemens (Wed, 24 Mar 2021 06:39:25 GMT):
@KonstantinRybalko Where is the `core.yaml`file you edited? Also I cannot see a volumes mount in `docker-compose-carbonAccounting.yaml` which mounts the `core.yaml`. Mount the `core.yaml` file to the following location: ```/opt/gopath/src/github.com/hyperledger/fabric/peer # env | grep "FABRIC_CFG_PATH" FABRIC_CFG_PATH=/etc/hyperledger/fabric /opt/gopath/src/github.com/hyperledger/fabric/peer # ls -l /etc/hyperledger/fabric total 36 -rw-r--r-- 1 root root 33378 Sep 30 18:39 core.yaml drwx------ 9 root root 288 Mar 24 06:32 msp drwx------ 12 root root 384 Mar 24 06:32 tls```

RobinKlemens (Wed, 24 Mar 2021 06:41:31 GMT):
I suggest you copy the `core.yaml` from https://github.com/opentaps/blockchain-carbon-accounting/blob/main/multi-cloud-deployment/fabric-config/core.yaml and rename the folder `./configtx` to `./fabric-config` and then also put the `core.yaml` there

RobinKlemens (Wed, 24 Mar 2021 06:45:07 GMT):
Thanks for forwarding my questions. As long as we don't run the fabric networks at the same version, we cannot "merge" our networks. However, I suggest you take a look at https://github.com/hyperledger-labs/blockchain-carbon-accounting/tree/main/multi-cloud-deployment That's our current configuration. We'll launch the network soon with three organizations. Each organization will host it's own fabric-ca, 1 orderer, and at least 1 peer

RobinKlemens (Wed, 24 Mar 2021 06:46:43 GMT):
Can you provide a link to your GitHub? Maybe it could also be an option for you to present your setup and chaincode in the next peer programming session on Monday https://wiki.hyperledger.org/display/CASIG/Carbon+Accounting+and+Certification+Working+Group

PeterCLARKE (Wed, 24 Mar 2021 06:48:53 GMT):
@RobinKlemens Good morning Robin. I am reading notes on handovers during the night. OK 1. No, v. 1.4 Fabric is not compatible with 2.0+ 2. Leave the Securitisation Blockchain at the Multi-Channel Level 3. Peter (me) to provision new blockchain v 2.0 + testnet .

PeterCLARKE (Wed, 24 Mar 2021 06:50:44 GMT):
@RobinKlemens I took a quick look at Github and the Emissions Token Network has 2 organizations which appear to be auditors.

KonstantinRybalko (Wed, 24 Mar 2021 16:49:50 GMT):
@RobinKlemens Thank you. I've made those changes. It worked. I was able install external chaincode. Continue working on the modifications to use it.

RobinKlemens (Wed, 24 Mar 2021 16:56:28 GMT):
Correct. This is the configuration of the current setup for local testing. However, once we move to a production-ready system, more organizations will host the network (at least 3). If the act as auditors is not decided yet

RobinKlemens (Wed, 24 Mar 2021 16:57:12 GMT):
Glad to hear that!! Thanks for your contribution!!! :hyperledger:

PeterCLARKE (Wed, 24 Mar 2021 19:41:26 GMT):
@RobinKlemens I am in heated agreement! Once you start to get to>15 organisations on Fabric, performance starts to degrade dramatically across all metrics. Latency, throughput, and the data validation pipeline. We can discuss at the peer programming meeting 1. Separating transaction data from metadata so that only transaction ID is needed to determine the transaction order 2) cache unmarshalled blocks at the committer and 3. use a hash table for state storage are reliable approaches to actually improve performance. What we used was not really a consensus algorithm as Kafka+ Zookeeper never proved a bottleneck.

PeterCLARKE (Wed, 24 Mar 2021 19:45:14 GMT):
@Robinklemens on Besu, that degrades at the atomic cross chain . This eThaler design is different as it is not ERC20. Thank you . Plan is to set up network to trade 'tokens (Account UXTO in our case) with main emissions channel.

@PeterCLARKE Handover. It looks to me like we can try a test with @SiChen and @RobinKlemens to 'trade' tokens.

robertjames77 (Wed, 24 Mar 2021 20:22:43 GMT):
@PeterCLARKE I will post to the Wiki my next draft of the securitisation document, handover to India and update the MURAL.

VipinB (Wed, 24 Mar 2021 21:12:51 GMT):
Thanks, I will take a look, maybe you can discuss how we can take this forward including a presentation in the CMSIG about securitization

RobinKlemens (Thu, 25 Mar 2021 09:53:15 GMT):
As said, we start with three organizations and I think it will take a long time (if ever) that we cross the number of 15 organizations. Since Fabric v. 2.x, Kafka and Zookeeper are deprecated. Also, Kafka only works properly within one Kubernetes cluster. We run the network in three different and independent clusters. Fabric 2.2 LTS uses a Raft-based consensus algorithm. In terms of chaincode performance, it would definitely make sense to review the chaincode `emissionscontract.js` If you could review the code and post your recommendations to GitHub in the form of issues, that would be great. https://github.com/hyperledger-labs/blockchain-carbon-accounting/blob/main/utility-emissions-channel/chaincode/node_ext/index.js

RobinKlemens (Thu, 25 Mar 2021 09:57:13 GMT):
What are the pro and cons of using eThaler (EIP 1155 or EIP 20) vs. UXTO (ERC20) token? Having a list of arguments for each solution could help the group to decide on the most suitable token implementation

PeterCLARKE (Thu, 25 Mar 2021 10:04:57 GMT):
@RobinKlemens Morning.

PeterCLARKE (Thu, 25 Mar 2021 10:05:21 GMT):
I do not agree about 15 orgs but it is irrelevant .

PeterCLARKE (Thu, 25 Mar 2021 10:06:05 GMT):
The reason is that Fabric can be reconfigured to workaround the bottleneck.

Drraghavendra99 (Thu, 25 Mar 2021 10:08:43 GMT):

Drraghavendra99 (Thu, 25 Mar 2021 10:08:44 GMT):
Welcome all of you

PeterCLARKE (Thu, 25 Mar 2021 10:08:48 GMT):
As you know, a standalone blockchain system is unusual at the production level. So,, the solution will involve integration and how that impacts end to end latency and throughput is something we will not know

PeterCLARKE (Thu, 25 Mar 2021 10:09:17 GMT):
Hello Raghavendra Please say hello to @RobinKlemens

Drraghavendra99 (Thu, 25 Mar 2021 10:09:21 GMT):
Great to see you and Grand Welcome

PeterCLARKE (Thu, 25 Mar 2021 10:09:54 GMT):
until we test.

Drraghavendra99 (Thu, 25 Mar 2021 10:10:12 GMT):
@RobinKlemens Very Glad and pleasure to meet you sir

PeterCLARKE (Thu, 25 Mar 2021 10:11:43 GMT):
@Raghavendra @RobinKlemens We will be joined by Mahavir at some point today. Mahavir is an expert in EO systems , ex Volvo Engineer

PeterCLARKE (Thu, 25 Mar 2021 10:13:27 GMT):

Nice to meet you all. Welcome

PeterCLARKE (Thu, 25 Mar 2021 10:17:31 GMT):
@RobinKlemens 1) on eThaler, Vip will be of help. I do not believe EIP20 is a secure protocol.

PeterCLARKE (Thu, 25 Mar 2021 10:18:27 GMT):
About 7 developers have been working with me but no one realised it

RobinKlemens (Thu, 25 Mar 2021 10:18:42 GMT):
Pleasure to meet you :)

PeterCLARKE (Thu, 25 Mar 2021 10:19:36 GMT):
Easily Solved. Sheerwood sent me a message from JIRA , Let's talk about the use case

PeterCLARKE (Thu, 25 Mar 2021 10:20:17 GMT):
use case @RobinKlemens @Drraghavendra99

Please see above link

PeterCLARKE (Thu, 25 Mar 2021 10:28:10 GMT):
The above link is a film of a Sumatran tiger being released back into the wild. It is a message that biodiversity has value. This was in Indonesia

PeterCLARKE (Thu, 25 Mar 2021 10:29:03 GMT):
@lewislinford @Drraghavendra99 @RobinKlemens The finance use case

PeterCLARKE (Thu, 25 Mar 2021 10:29:41 GMT):
Is a network for Sukuk bonds and other Shari'a financings. https://blossomfinance.com/posts/sukuk-on-blockchain-a-legal-regulatory-and-shariah-review

PeterCLARKE (Thu, 25 Mar 2021 10:30:50 GMT):
Both Indonesia and Malaysia are of the Muslim Faith . Thus the structure should be appropriate

PeterCLARKE (Thu, 25 Mar 2021 10:31:22 GMT):
These documents will be in our wiki along with a securitisation document from Robert .

knagware9 (Thu, 25 Mar 2021 14:21:49 GMT):
Great to see all these conversations and new members joined group

RobinKlemens (Thu, 25 Mar 2021 16:47:46 GMT):
@PeterCLARKE how do you think these documents fit into the mission of the CA2SIG? https://wiki.hyperledger.org/display/CASIG/Climate+Action+and+Accounting+SIG+Home The use cases sound very interesting. However, I'm not sure if the Hyperledger Climate SIG is the right place for them. Yes, biodiversity has value to climate but I think more on a global scale than based on species like the Sumatran tiger.

PeterCLARKE (Fri, 26 Mar 2021 01:47:26 GMT):
@RobinKlemens Excellent point about "biodiversity having value to the climate ...on a global scale" . I see this identification of value as within scope of the Climate SIG , through the work of Nova.org (Christian) OS Climate (Tom, Martin) . The video of the tiger was to welcome new members joining from Indonesia and Malaysia.

PeterCLARKE (Fri, 26 Mar 2021 01:51:24 GMT):
A story about the Black Forest (and the acid rain from RWE) or the English countryside, California Coast, are other examples of the global value of these fragile ecosystems.

lewislinford (Fri, 26 Mar 2021 02:08:30 GMT):
What we are doing here is we are using the video. The video is a human interest story to welcome new members to personalise our own experience with climate change we want to share the message that computer sience is alot more inclusive than people think.

lewislinford (Fri, 26 Mar 2021 02:13:04 GMT):
Professor Anita Lundberg would be a great value to the community.

SherwoodMo (Fri, 26 Mar 2021 03:32:29 GMT):
@PeterCLARKE @lewislinford - I've got to agree with @RobinKlemens Peter and Lewis. It is important to keep our content and discussions related to the scope of the SIG. The video of the Sumatran Tiger is outside of the mission and scope of the SIG.

robertjames77 (Fri, 26 Mar 2021 08:36:57 GMT):
A securitization is a form of financing. You pool little projects in Africa and Indonesia to get to a certain scale. These projects are typically off-grid solar projects. Pooling them is done by blockchain .

robertjames77 (Fri, 26 Mar 2021 08:40:02 GMT):
The video is a human interest story about projects that interest new members. As we have some from Indonesia, we chose the Sumatra Tiger.

robertjames77 (Fri, 26 Mar 2021 08:43:42 GMT):
@SherwoodMo @RobinKlemens We changed the video to be in a format like SiChen suggested, but a group one to accommodate more people! These can go on member pages in the Wiki.

robertjames77 (Fri, 26 Mar 2021 08:51:08 GMT):
@knagware9 @RobinKlemens We looked at provisioning a Fabric v2.0 blockchain starting with 2 orgs and an Orderer.

robertjames77 (Fri, 26 Mar 2021 08:53:28 GMT):
This blockchain is at the Utility Emissions Level . A separate chain is needed for the Emissions Token Network based upon eThaler. We will build this and then see if we can join them.

robertjames77 (Fri, 26 Mar 2021 08:53:40 GMT):
Tigers negotiable:)

@RobinKlemens @sichen In terms of chaincode performance, it would definitely make sense to review the chaincode emissionscontract.js If you could review the code and post your recommendations to GitHub in the form of issues, that would be great.

[ ](https://chat.hyperledger.org/channel/climate-action-sig?msg=uPDJAh7J3SJ5JaQD5) Confirming that we will review the emissionscontract.js as reflected in the 'good first things' to do list (Wiki - Issue List)

robertjames77 (Fri, 26 Mar 2021 09:52:32 GMT):
We will look at the auto-testing and API from EIA as described in the issue list. We will not issue a PR until coordinating with @sichen . Thank you

Hyperledger-labs: multi-cloud-deployment thread

RobinKlemens (Fri, 26 Mar 2021 10:37:13 GMT):
This thread is just intended to be used for activities around the multi-cloud deployment of Hyperledger Fabric. https://github.com/hyperledger-labs/blockchain-carbon-accounting/tree/main/multi-cloud-deployment We use this thread to coordinate the launch of the network.

RobinKlemens (Fri, 26 Mar 2021 10:39:34 GMT):
@pavelkrolevets @sichen @KonstantinRybalko Can you provide the following information so I can create the `configtx.yaml` file for the Hyperledger Fabric network we gonna launch, please. - Domain and port of orderer (e.g. fabric-orderer1.emissionsaccounting.emitras.de:443) - Domain and port of anchor peer - Name of your organization Thx :)

robertjames77 (Fri, 26 Mar 2021 10:48:00 GMT):
Robin, this looks like an ideal time to harmonise collaboration.

robertjames77 (Fri, 26 Mar 2021 10:49:05 GMT):
Just confirming: Fabric Network is based upon 'marbles' asset transfer example . This is according to the github link.

robertjames77 (Fri, 26 Mar 2021 10:52:17 GMT):
Section 5.5 5.6 Is further chaincode needed (Marbles - Other Asset) ?

RobinKlemens (Fri, 26 Mar 2021 10:58:42 GMT):
The chaincode you are referring to is just for testing purposes as the chapter states https://github.com/udosson/blockchain-carbon-accounting/tree/main/multi-cloud-deployment#44-test-your-infrastructure-against-the-test-configuration We deploy `emissionscontract.js` to the network. https://github.com/hyperledger-labs/blockchain-carbon-accounting/tree/main/utility-emissions-channel/chaincode/node_ext

RobinKlemens (Fri, 26 Mar 2021 10:58:42 GMT):
Robert, he chaincode you are referring to is just for testing purposes as the chapter states https://github.com/udosson/blockchain-carbon-accounting/tree/main/multi-cloud-deployment#44-test-your-infrastructure-against-the-test-configuration We deploy `emissionscontract.js` to the network. https://github.com/hyperledger-labs/blockchain-carbon-accounting/tree/main/utility-emissions-channel/chaincode/node_ext

Securitisation Blockchain

RobinKlemens (Fri, 26 Mar 2021 10:59:57 GMT):
I created an issue for you. Please use the comment function there for further communication. Thanks for your help. https://github.com/hyperledger-labs/blockchain-carbon-accounting/issues/112

robertjames77 (Fri, 26 Mar 2021 11:02:18 GMT):
@RobinKlemens Thank you for creating the issue and organising the threads. I created separate channels or threads based upon this good idea.

robertjames77 (Fri, 26 Mar 2021 11:05:45 GMT):
Normally I would make this comment in the Channel on Github. The issue is too technical for me, but I will handoever to Peter.

robertjames77 (Fri, 26 Mar 2021 11:08:01 GMT):
This is about performance. At some point there is the contemplated use of BESU. Would that be at the Emissions Token Network - Net Emissions Network Tier? If so, I will let Peter comment about Caliper. Thank you.

robertjames77 (Fri, 26 Mar 2021 11:08:54 GMT):
I understand the immediate issue is the performance of emissioncontract.js .

RobinKlemens (Fri, 26 Mar 2021 11:09:48 GMT):
The chaincode works. It's more a review. This is not time critical

robertjames77 (Fri, 26 Mar 2021 11:10:06 GMT):
What is time critical for you?

robertjames77 (Fri, 26 Mar 2021 11:11:26 GMT):
We have capacity.

RobinKlemens (Fri, 26 Mar 2021 11:49:45 GMT):
At the moment I recommend to start with one of the good-first-issues. These are selected by @sichen . We can prioritize in the Peer Programming Call on Monday

SherwoodMo (Fri, 26 Mar 2021 14:10:53 GMT):
@robertjames77 If you post a video outside the scope of the SIG, I'm afraid I'm going to have to ask you to take it down @robertjames77

SherwoodMo (Fri, 26 Mar 2021 14:27:23 GMT):
(Related to the Sumatra tiger, of course ;) Member testimony is welcome as long as the focus is on the work and mission of the SIG).

robertjames77 (Fri, 26 Mar 2021 15:30:13 GMT):
OK, No group video!

robertjames77 (Fri, 26 Mar 2021 15:37:16 GMT):
The easier it is for members to onboard the better.

SherwoodMo (Fri, 26 Mar 2021 15:37:33 GMT):
Thanks for your understanding :)

robertjames77 (Fri, 26 Mar 2021 15:40:41 GMT):
Sherwood, I care about the big picture here. When we are asked to bring in Stanford or COP26, and do so, then it is embarrassing to ask them to wait. If Si needs projects, then you have to go to Indonesia or Latin America to get them. That's all.

robertjames77 (Fri, 26 Mar 2021 15:42:46 GMT):
So, what would you like me to do with PandU of the Blockchain Indoneisa Society and Friends? Here, I can put together something in Bahasa, their native language. It is all about Si needing a project and I am here to help. Tigers notwithstanding.

SherwoodMo (Fri, 26 Mar 2021 15:44:33 GMT):
Thanks Robert, I think just use your best judgement. As long as the content that we publish and the conversations that we have focus directly focused on the work of the SIG, then we are in good shape.

robertjames77 (Fri, 26 Mar 2021 15:44:34 GMT):
In the meantime, we can look at some of these programming issues as they are less ethereal.

sichen (Fri, 26 Mar 2021 15:45:40 GMT):
Robert thank you for your help here. If someone in Indonesia is interested in working with us, would they like to join a call, email our list so we can find out what they'd like?

sichen (Fri, 26 Mar 2021 15:46:27 GMT):
The video idea is just to talk about the members of the group and what they're working on. There are a lot of issues related to climate, but right now we need to focus a bit.

robertjames77 (Fri, 26 Mar 2021 15:47:05 GMT):
The focus is on the international climate conference and a project involving blockchain.

sichen (Fri, 26 Mar 2021 15:49:32 GMT):
Robert I'm just confused. What are you and your colleagues looking to do? Are you looking to use our code to do a project? Writing new code?

robertjames77 (Fri, 26 Mar 2021 15:49:33 GMT):
Yes, we have the entire blockchain society of indonesia and a couple from malaysia, plus bankers and others expert in Shari'a finance.

robertjames77 (Fri, 26 Mar 2021 15:49:57 GMT):
The confusion is because of separate email threads, no more.

robertjames77 (Fri, 26 Mar 2021 15:51:03 GMT):
I believe we share the same purpose. Simplicity. We have a 11 blockchains, 1 in production. Some of the 11 can be cannabalised based upon the code in Hyperledger Labs.

robertjames77 (Fri, 26 Mar 2021 15:53:41 GMT):
Rather than me type up stuff in a channel, why don't I send you a roadmap of one page!

sichen (Fri, 26 Mar 2021 16:18:36 GMT):
That's great. Would you like me to join one of your group meetings so I could talk about what we're doing and learn about what they're interested in?

KonstantinRybalko (Fri, 26 Mar 2021 17:40:52 GMT):
@RobinKlemens organization: opentaps OrdererEndpoints: - fabric-orderer.opentaps.net:443 AnchorPeers: - Host: fabric-peer.opentaps.net Port: 443 One question. I saw you committed *.pem and *.crt. Are they public keys ?

RobinKlemens (Fri, 26 Mar 2021 17:44:14 GMT):
yes, they are just public keys and we need them for TLS communication and Fabric's MSP. See: https://hyperledger-fabric.readthedocs.io/it/release-2.2/create_channel/create_channel_config.html#organizations and https://hyperledger-fabric.readthedocs.io/it/release-2.2/create_channel/create_channel_config.html#orderer

RobinKlemens (Fri, 26 Mar 2021 17:45:17 GMT):
To be sure that you don't upload private information you can decrypt the certificates with `openssl x509 -text -noout -in ./path-to-cert-file` and check the information

KonstantinRybalko (Fri, 26 Mar 2021 17:46:46 GMT):
Ok, so what I need is just commit same structure for organization 'opentaps' with keys which was used for cluster deployment. Right ?

RobinKlemens (Fri, 26 Mar 2021 17:48:08 GMT):
yes, right. Be sure to only upload as much certificates as needed. Do the same for opentabs: ```├── emitras │ ├── msp │ │ ├── cacerts │ │ │ └── fabric-ca-emissionsaccounting-emitras-de-443-fabric-ca-emissionsaccounting-emitras-de.pem │ │ ├── config.yaml │ │ └── tlscacerts │ │ ├── ca.crt │ │ └── tlsca.emissionsaccounting.emitras.de-cert.pem │ └── orderers │ └── fabric-orderer1.emissionsaccounting.emitras.de │ └── tls │ └── server.crt```

KonstantinRybalko (Fri, 26 Mar 2021 17:48:23 GMT):
ok

RobinKlemens (Fri, 26 Mar 2021 17:50:40 GMT):
I'll update the `configtx.yaml` file once you and @pavelkrolevets have uploaded the public information. Also, I'll create the channel artifacts for the orderer and peer nodes and upload them as well. However, with all the information of the three organizations and the `configtx.yaml` file you could create the channel artifacts on your own

KonstantinRybalko (Fri, 26 Mar 2021 18:21:12 GMT):
I've created opentaps network artifacts they are here https://github.com/hyperledger-labs/blockchain-carbon-accounting/tree/main/multi-cloud-deployment/network-artifacts/organizations/opentaps

@RobinKlemens Hi, Robin I'm continue working on docker-compose-setup chaincode ext Trying to deploy ext chaincode with new script deployCCExt.sh, it is similar we have in the deploy-aws but got an error: Error: failed to retrieve broadcast client: orderer client failed to connect to orderer1.auditor1.carbonAccounting.com:7050: failed to create new connection: context deadline exceeded Why do you think it could be happened ? Can you take a look at my latest commits in the https://github.com/opentaps/blockchain-carbon-accounting when you have a chance

RobinKlemens (Mon, 29 Mar 2021 15:19:56 GMT):
Can you send orderer logs, please?

RobinKlemens (Mon, 29 Mar 2021 16:31:43 GMT):
@KonstantinRybalko my orderer is up and runnig

KonstantinRybalko (Mon, 29 Mar 2021 16:57:15 GMT):
@RobinKlemens I've deleted orderer and peer recreated system-genesis-block map restared orderer but it is on the Init:0/1 status now

RobinKlemens (Mon, 29 Mar 2021 17:10:11 GMT):
what is the status of your orderer now?

KonstantinRybalko (Mon, 29 Mar 2021 17:10:32 GMT):
it is same Init:0/1

RobinKlemens (Mon, 29 Mar 2021 17:11:38 GMT):
okay. Can you check the logs of your init container? I have a feeling that the secret `orderer1-crypto` could be missing in your namespace

KonstantinRybalko (Mon, 29 Mar 2021 17:12:50 GMT):
I tried to see log, but it says Error from server (BadRequest): container "fabric-orderer" in pod "fabric-orderer-6b94b74596-sx6jt" is waiting to start: PodInitializing

KonstantinRybalko (Mon, 29 Mar 2021 17:14:03 GMT):
what is orderer1-crypto ?

RobinKlemens (Mon, 29 Mar 2021 17:14:59 GMT):
See step 2 https://github.com/hyperledger-labs/blockchain-carbon-accounting/tree/main/multi-cloud-deployment/deploy-aws#42-orderer

RobinKlemens (Mon, 29 Mar 2021 17:15:37 GMT):
The secret is called `orderer-crypto`

KonstantinRybalko (Mon, 29 Mar 2021 17:16:48 GMT):
but it was there before do you mean it should be recreated as well ?

KonstantinRybalko (Mon, 29 Mar 2021 17:17:29 GMT):
but it looks like nothing changed for it

RobinKlemens (Mon, 29 Mar 2021 17:17:43 GMT):
Have you created the pvc?

RobinKlemens (Mon, 29 Mar 2021 17:18:01 GMT):
Is the pvc used by any other container?

KonstantinRybalko (Mon, 29 Mar 2021 17:19:56 GMT):
PersistentVolumeClaim still be same I've run kubectl delete -f ./fabric-orderer-deployment.yaml -n fabric-production recreated system-genesis-block and run kubectl apply -f ./fabric-orderer-deployment.yaml -n fabric-production again

RobinKlemens (Mon, 29 Mar 2021 17:20:23 GMT):
You need to recreate pvc as well

RobinKlemens (Mon, 29 Mar 2021 17:21:03 GMT):
Otherwise you would use the old configuration, ledger data etc.

KonstantinRybalko (Mon, 29 Mar 2021 17:21:21 GMT):
i.e. it is better to create new ec2 volume , right ?

pritam_01 (Mon, 29 Mar 2021 17:22:54 GMT):
Is it necessary to have S3 cred in order to run api server ? or do we have in-Memory-Wallet implement? actually I don't have a AWS account @RobinKlemens

KonstantinRybalko (Mon, 29 Mar 2021 17:24:35 GMT):
actually, when I deleted it , pvc also seems deleted persistentvolume "pv-static-fabric-orderer" deleted service "fabric-orderer" deleted persistentvolumeclaim "fabric-orderer" deleted deployment.apps "fabric-orderer" deleted

RobinKlemens (Mon, 29 Mar 2021 17:25:43 GMT):
okay. So the step `Create ebs volume` is done

KonstantinRybalko (Mon, 29 Mar 2021 17:25:58 GMT):
1 sec

RobinKlemens (Mon, 29 Mar 2021 17:26:07 GMT):
you have created `system-genesis-block`configmap

RobinKlemens (Mon, 29 Mar 2021 17:26:42 GMT):
and created a secret containing all the crypto material of the orderer called `orderer-crypto`

KonstantinRybalko (Mon, 29 Mar 2021 17:30:25 GMT):
I've created new volume and run kubectl apply -f ./fabric-orderer-deployment.yaml -n fabric-production again and got persistentvolume/pv-static-fabric-orderer created service/fabric-orderer created persistentvolumeclaim/fabric-orderer created deployment.apps/fabric-orderer created but orderer again in status Init fabric-production fabric-orderer-6b94b74596-n759t 0/1 Init:0/1 0 107s

RobinKlemens (Mon, 29 Mar 2021 17:31:21 GMT):
Are you able to retrieve the logs of the init container?

KonstantinRybalko (Mon, 29 Mar 2021 17:32:06 GMT):
log says Error from server (BadRequest): container "fabric-orderer" in pod "fabric-orderer-6b94b74596-n759t" is waiting to start: PodInitializing

KonstantinRybalko (Mon, 29 Mar 2021 17:32:11 GMT):
nothing else

RobinKlemens (Mon, 29 Mar 2021 17:33:42 GMT):
can you run `kubectl describe pod fabric-orderer-6b94b74596-n759t` and post the output here?

sichen (Mon, 29 Mar 2021 17:34:23 GMT):
No it is not. We have the serverless option to run s3 locally

KonstantinRybalko (Mon, 29 Mar 2021 17:34:58 GMT):
1 sec, it seems it cannot mount a volume

RobinKlemens (Mon, 29 Mar 2021 17:35:03 GMT):
and run `kubectl logs fabric-orderer-6b94b74596-n759t -c init-container-orderer` please and also post the logs

sichen (Mon, 29 Mar 2021 17:36:17 GMT):
See https://github.com/opentaps/blockchain-carbon-accounting/blob/main/utility-emissions-channel/README.md#running-the-fabric-network-and-express-api

pritam_01 (Mon, 29 Mar 2021 17:36:24 GMT):
thanks , API server is now running :grin:

sichen (Mon, 29 Mar 2021 17:36:33 GMT):
great

it is running eventually fabric-production fabric-orderer-6b94b74596-jgtpm 1/1 Running 0 86s

KonstantinRybalko (Mon, 29 Mar 2021 17:40:11 GMT):
sometimes it cannot mount a volume

KonstantinRybalko (Mon, 29 Mar 2021 17:40:30 GMT):
so what do we do next ?

KonstantinRybalko (Mon, 29 Mar 2021 17:40:41 GMT):
starting a peer ?

RobinKlemens (Mon, 29 Mar 2021 17:41:48 GMT):
Check the logs fo your orderer and see if it's communicating with `fabric-orderer1.emissionsaccounting.emitras.de`

RobinKlemens (Mon, 29 Mar 2021 17:42:14 GMT):
It looks good in my logs :)

KonstantinRybalko (Mon, 29 Mar 2021 17:43:55 GMT):

RobinKlemens (Mon, 29 Mar 2021 17:46:42 GMT):
Then we can both start our peers and then make them join the channel

KonstantinRybalko (Mon, 29 Mar 2021 17:47:17 GMT):
ok, I'll start a peer now

RobinKlemens (Mon, 29 Mar 2021 17:47:43 GMT):

But don't deploy chaincode yet

RobinKlemens (Mon, 29 Mar 2021 17:54:44 GMT):
eeehm. Wait please

KonstantinRybalko (Mon, 29 Mar 2021 17:55:03 GMT):
ok

Drraghavendra99 (Mon, 29 Mar 2021 17:55:29 GMT):
Hi Everyone Very Glad to meet all of you

RobinKlemens (Mon, 29 Mar 2021 17:55:33 GMT):
I create the channel and upload the channel blog to our repo. You can copy it from there. Otherwise we would create the channel twice

PeterCLARKE (Mon, 29 Mar 2021 17:57:02 GMT):
Hello Raghavendra . We are setting up blockchain networks in Fabric & Ethereum.

RobinKlemens (Mon, 29 Mar 2021 17:57:40 GMT):
It's merged https://github.com/hyperledger-labs/blockchain-carbon-accounting/pull/124

Drraghavendra99 (Mon, 29 Mar 2021 17:57:55 GMT):
``` Great News ```

RobinKlemens (Mon, 29 Mar 2021 17:58:17 GMT):
The file is located under: `./network-artifacts/genesis-files/utilityemissionchannel.block `

RobinKlemens (Mon, 29 Mar 2021 17:58:42 GMT):
Oh sorry. I did something wrong

RobinKlemens (Mon, 29 Mar 2021 17:58:58 GMT):
Don't use this file. I'll upload the correct one in a minute

KonstantinRybalko (Mon, 29 Mar 2021 17:59:11 GMT):
ok

RobinKlemens (Mon, 29 Mar 2021 18:02:53 GMT):
Seems like I updated the correct one

RobinKlemens (Mon, 29 Mar 2021 18:03:02 GMT):
So let's try to join the channel

RobinKlemens (Mon, 29 Mar 2021 18:03:11 GMT):
https://github.com/hyperledger-labs/blockchain-carbon-accounting/blob/main/multi-cloud-deployment/network-artifacts/genesis-files/utilityemissionchannel.block

RobinKlemens (Mon, 29 Mar 2021 18:06:38 GMT):
remember to reference the correct block file in the following command `./bin/peer channel join -b ./network-artifacts/genesis-files/utilityemissionchannel.block`

KonstantinRybalko (Mon, 29 Mar 2021 18:09:09 GMT):
do I need create or just join the channel ?

RobinKlemens (Mon, 29 Mar 2021 18:09:34 GMT):
Just join

RobinKlemens (Mon, 29 Mar 2021 18:09:46 GMT):
Source env, then join :)

RobinKlemens (Mon, 29 Mar 2021 18:13:32 GMT):
That's what we want to see

KonstantinRybalko (Mon, 29 Mar 2021 18:13:51 GMT):
but what about error ?

RobinKlemens (Mon, 29 Mar 2021 18:14:03 GMT):
Did you run the command twice?

KonstantinRybalko (Mon, 29 Mar 2021 18:14:17 GMT):
I don't think so

RobinKlemens (Mon, 29 Mar 2021 18:14:38 GMT):
mmh

RobinKlemens (Mon, 29 Mar 2021 18:14:48 GMT):
Did you delete pvc before starting peer?

RobinKlemens (Mon, 29 Mar 2021 18:14:48 GMT):
Did you delete the pvc before starting peer?

KonstantinRybalko (Mon, 29 Mar 2021 18:15:20 GMT):
yes, delete everything and created new volume

RobinKlemens (Mon, 29 Mar 2021 18:18:41 GMT):
What is the output of `./bin/peer channel getinfo -c utilityemissionchannel` ?

KonstantinRybalko (Mon, 29 Mar 2021 18:23:08 GMT):
hmm let me recreate a peer again

sichen (Mon, 29 Mar 2021 18:23:21 GMT):

RobinKlemens (Mon, 29 Mar 2021 18:34:44 GMT):
Can you share the link to the configtx.yaml file to me that you used before?

RobinKlemens (Mon, 29 Mar 2021 18:35:58 GMT):
and also make sure you use the right certificates to perform the peer channel operation

KonstantinRybalko (Mon, 29 Mar 2021 18:40:12 GMT):
I've added that file to discord

KonstantinRybalko (Mon, 29 Mar 2021 18:40:40 GMT):
and how to check right certificates ?

KonstantinRybalko (Mon, 29 Mar 2021 18:42:07 GMT):
perhaps something should be changed in the setEnv.sh ?

RobinKlemens (Mon, 29 Mar 2021 18:42:17 GMT):
maybe

RobinKlemens (Mon, 29 Mar 2021 18:42:40 GMT):
Make sure the paths are referring to the current certificates you use

RobinKlemens (Mon, 29 Mar 2021 18:43:19 GMT):
Unfortunately I need let's catch up tomorrow and continue with the deployment

yes I will be applying for "Implement Client Side Security for Climate SIG Fabric Application" since I have already worked on fabric-client extensively in my previous internship with an start-up. Fabric and ethereum integration with Cactus also excites me, and will learn about cactus. for time being (before internship starts in June) I will try to resolve as much as good-for-first issue I can, this will give me more clarity about the mission and the code-base.

I've fixed this error eventually. Did not notice that is was at the moment of the chaincode commit on the first place. Added 20 sec pause after chaincode checkcommitreadiness and it worked. So, utility-emissions-channel/docker-compose-setup works with external chaincode now, and I am able to record emission locally from opentaps_seas.

Last week, we launched our Hyperledger Fabric network running in two different Kubernetes clusters at the moment. We started with setting up the utility emissions channel (https://wiki.hyperledger.org/display/CASIG/Utility+Emissions+Channel). To check the current state of the network you can access https://explorer.emissionsaccounting.emitras.de/ (which is now secured with TLS) Username: ca2sig Password: ca2sig1234 If anyone wants to join the network, we have the readme ready for DigitalOcean and AWS EKS. The readme (https://github.com/hyperledger-labs/blockchain-carbon-accounting/tree/main/multi-cloud-deployment) helps you to set up a fabric network in one Kubernetes cluster. If all the tests pass you're ready to join our production-grade network. Looking forward to onboarding more organizations, chaincodes, and use cases. Cheers, Robin

PeterCLARKE (Mon, 05 Apr 2021 18:49:24 GMT):

Hello , I am facing this error while invoking `emissionscontract/recordEmissions` API endpoint . both the chaincode are running And why CHAINCODE_CCID for chaincode container is hard-coded `https://github.com/hyperledger-labs/blockchain-carbon-accounting/blob/9fae0649c5fbba5e21987ac121c60e2e5e71fa5c/utility-emissions-channel/docker-compose-setup/docker/nodes/node-one/docker-compose-chaincode.yaml#L15` ?

Hi @Pritam 12, thanks for reporting the error. Could you create an issue for this in GitHub? If the CCID is hard-coded we need to fix this

Yes pls let us know all the steps you took to get to this point. We'll take a look.

@aaruj Haven't seen it before, but I welcome the idea for sure. I hope they manage to get something done with how things currently are with proof of work mining of Bitcoin for example (difficult task and I have no idea how it would be achieved, but I'm really glad someone is working on this)

Hi everyone. My name is Evan - I discovered this community via the Blockchain DLT dev role posting for Open Source Strategies on angel.co. I am interested in learning more about the application of blockchain to the problem space of climate change in regard to how to design systems to avoid creating misaligned incentives (i.e. U.S. Organic certification, Dolphin-Safe). Also curious to see how blockchain can be leveraged to track reforestation efforts over time. I have recently been writing an integration against the DigitalHumani Reforestation as a Service API, but I have concerns over the long term quality enforcement of underlying projects.

Hey everyone! I'm Harsh Sharma, and I'm a pre-final year undergraduate student at IIIT, Gwalior. I've been working on an end-to-end project over the past three months using Hyperledger Fabric, Node.js, Express, Fabric Node SDKs with TypeScript, and Svelte for the client-side applications. I've learnt about a lot of new technologies in the process and I'm hoping to publish a paper about the same. I'm really excited about using Fabric and other blockchain technologies for decentralized applications, and when I saw this SIG I was really eager to be a part of the project. Thank you :).

hs2361 (Sun, 01 Aug 2021 12:40:12 GMT):
@RobinKlemens I had 3 suggestions for the utility emissions project: 1. Migrate all cryptographic operations from crypto-js to node-forge, since Forge supports 512 bit keys, SHA3 hashing, and has higher performance over crypto-js. Native crypto (Node) may also be used to avoid external dependencies altogether. 2. Enforce a style guideline with a Linter such as ESLint and add a config file. 3. Improve visualizations by integrating something like Grafana, or we can even consider developing a Fabric plugin for Grafana (for Explorer perhaps). Do let me know if you have suggestions! These are just a few ideas I had in mind.

How climate action can drive our economic future’ also reveals how the country could gain US$11 trillion in economic value instead over the same period, by limiting rising global temperatures and realising its potential to ‘export decarbonisation’ to the world. From 2030 to 2040, India and the world would need to complete large and coordinated shifts to reduce carbon emissions by tackling how energy is produced and consumed.

hs2361 (Wed, 15 Sep 2021 19:10:47 GMT):
Hi everyone, I was working on issue #80 (https://github.com/hyperledger-labs/blockchain-carbon-accounting/issues/80). Thanks @pritam_01 for helping me with the step about editing the /etc/hosts file. The E2E tests are running normally (7 passing). However, as described in the issue, the automated tests are failing. I ran the tests using `npx mocha ./tests --timeout 10000` as described in the README. I'm attaching a screenshot here after running the tests. 3 of them are failing. Could someone please confirm whether these are the tests that are failing? I can look into them accordingly then.

pritam_01 (Thu, 16 Sep 2021 03:20:21 GMT):
Please run end to end test, by npm run test

hs2361 (Thu, 16 Sep 2021 04:06:17 GMT):
Yes, that's what I did to run the E2E tests. They're passing. However the other tests inside of the test.js file are not passing.

pritam_01 (Thu, 16 Sep 2021 04:23:27 GMT):
You can delete that, cuz e2e covers every case that test.js does.

hs2361 (Thu, 16 Sep 2021 04:24:00 GMT):
Oh is that the case? Then the issue is no longer relevant.

Hello! I'm Aarjav Chauhan, a phd student at the University of Toronto in Computer Science. I'm researching open development for climate action and sustainable development and have found the Hyperledger to be an amazing project with potential for introducing blockchain technology to ensure transparency in sustainability within developing communities. I'm still learning about the Hyperledger ecosystem but I would really appreciate connecting further with people in the space!
