@danintel I started trying to add people to https://github.com/orgs/hyperledger/teams/avalon-maintainers/members and I see a bunch of the usernames in this file: https://github.com/hyperledger/avalon/blob/master/CODEOWNERS are invalid GitHub usernames. Could I ask you to submit a PR to fix that file, and tell me who to add to the maintainers group?

danintel (Tue, 24 Sep 2019 20:11:27 GMT):
That is a hysterical artifact of when the repo was hosted at Intel. Soor initial maintainers just use .... manju956 @danintel @TomBarnes @srinathduraisamy @manojgop @Karthika @ram-srini @EugeneYYY I will submit a PR

OK @danintel I've added/invited all of those people to https://github.com/orgs/hyperledger/teams/avalon-maintainers/members - do I need to undo this and move this repo back to labs?

danintel (Tue, 24 Sep 2019 20:31:27 GMT):
I just spoke to @EugeneYYY (he is next to me). He says to start with Avalon empty for now. So undo the move and move it back to labs. The CODEOWNERS change can remain (but does not have to).

Will the new repo be a squash commit or something?

rjones (Tue, 24 Sep 2019 20:39:08 GMT):
@EugeneYYY ?

danintel (Tue, 24 Sep 2019 20:44:01 GMT):
@rjones No squash commits--preserve the commit history if possible. It is waiting for approval from Intel. Sorry for the confusion. @EugeneYYY says a simple placeholder note pointing to the HL labs repo is all that's needed for now.

rjones (Tue, 24 Sep 2019 20:46:21 GMT):
OK. Now I'm more confused as to your goal.

rjones (Tue, 24 Sep 2019 20:46:40 GMT):
Is the code in the avalon repo the code that is coming in, or not?

danintel (Tue, 24 Sep 2019 20:51:04 GMT):
Yes, it is the code that is coming in. @EugeneYYY says we need approval before populating Avalon.

rjones (Tue, 24 Sep 2019 20:51:17 GMT):
Approval from ?

danintel (Tue, 24 Sep 2019 20:52:03 GMT):
Intel internal corporate approval.

Hi @danintel and @EugeneYYY . Can you elaborate why moving code from the labs repo to the main avalon repo needs Intel's legal approval? It's already Hyperledger code, contributed with a DCO (right?)

EugeneYYY (Tue, 24 Sep 2019 21:40:07 GMT):
We have several companies actively working on and contributing to the TCF github. We need to synchronize everybody to make sure that everybody will switch at once to the new repository. We learned only today that a new repo is available so within a couple days will move everybody at once to the new repo

rjones (Tue, 24 Sep 2019 21:41:15 GMT):
all of the git remotes should magically work.

rjones (Tue, 24 Sep 2019 21:41:31 GMT):
when you move or rename a repo, github does some magic redirects

EugeneYYY (Tue, 24 Sep 2019 21:49:40 GMT):
We are new to this process and everybody under pressure to have code done by Eth DevCon V so nobody wants any surprises at the critical time. I assume we also need to copy all TCF maintainers to Avolan.

bbehlendorf (Tue, 24 Sep 2019 22:01:32 GMT):
@EugeneYYY That's great that there are contributors from several different companies (we prefer to talk about individuals, not corporations, as the active folks here). Coordinating with them on a move and making sure github redirects etc are in place is important. Just wasn't clear why legal needs to be involved. Are we talking about other new code not already in the Labs repo?

rjones (Tue, 24 Sep 2019 22:01:51 GMT):
@EugeneYYY those changes are already gone with the first move. The maintainers list was reset.

rjones (Tue, 24 Sep 2019 22:03:02 GMT):
https://github.com/orgs/hyperledger/teams/avalon-maintainers/members contains the current list.

EugeneYYY (Tue, 24 Sep 2019 22:04:09 GMT):
Yes some contributors have code (almost) ready and in the process pushing of their code

EugeneYYY (Tue, 24 Sep 2019 22:04:20 GMT):
Intel legal is not involved

EugeneYYY (Tue, 24 Sep 2019 22:08:55 GMT):
@rjones I looked at the maintainers list, but it is not the same as for TCF, e.g. there is no Manoj. Only tom and Dan are maintainers. We feel it is safer to postpone transition until Avalon/TCF team is aware and ready for transition. I will get back to you within couple days (folks are across diff geographies)

bbehlendorf (Tue, 24 Sep 2019 22:09:23 GMT):
ah, ok, my mistake

rjones (Tue, 24 Sep 2019 22:20:11 GMT):
@EugeneYYY all of the settings are gone. Moving it back to labs does not bring those settings back

TomBarnes (Tue, 24 Sep 2019 22:21:51 GMT):
Hi, Brian, Ry. We have some internal processes here at Intel that are involved with ensuring the quality of the code we submit to open source projects. When we make the transitions from HL Labs to HL top level project, we want to make sure that the quality fo the code matches the destination. We think everythring is ready for that transition, but would like to reveiw and receive approval from our immediate mamagment before we make that transitions. That review will take place next Tuesday. If HL can accomidate that delay, it will make our lives as Intel contributures a bit easier.

danintel (Thu, 24 Oct 2019 20:07:54 GMT):
@rjones @EugeneYYY The plan is to populate the other three repos later, but for now you can create empty repos for the other three with the same access rights. Move https://github.com/hyperledger-labs/trusted-compute-framework to https://github.com/hyperledger/avalon (and a redirect would from the former to latter would be great too) .

That is because they are members of `hyperledger-labs` but *not* members of `hyperledger`, so I get an error when I try to add them.

hey all 👋 first of all thanks for the hardwork on this project 👍 i've been through most of the docs of the repo (not the spec I'll give you that 🙇 ) and successfully (at least I thought) developed my first workload based on the tutorial and other example apps my workload works outside of TCF (built it as a separate standalone C++ app) but i cna't get it to work in TCF

jopasserat (Wed, 30 Oct 2019 12:16:55 GMT):
i know that the workload is recognised succesfully has the TCF behaves differently with a random workload id

jopasserat (Wed, 30 Oct 2019 12:17:08 GMT):
other example apps work fine

jopasserat (Wed, 30 Oct 2019 12:17:28 GMT):
and i'm using the `generic_client.py` script to submit my work order

jopasserat (Wed, 30 Oct 2019 12:17:52 GMT):
TLDR: i'm after the common mistakes / troubleshooting procedure i could go through to debug my workload

manojgop (Wed, 30 Oct 2019 14:15:53 GMT):
@jopasserat can you check if your workload is registered successfully. You can build TCF with debug flag TCF_DEBUG_BUILD=1 and check for log messages regarding registration of workload. This will also enable enclave logs.

jopasserat (Wed, 30 Oct 2019 15:28:40 GMT):
what message should I look for in the lojgs?

jopasserat (Wed, 30 Oct 2019 15:28:40 GMT):
what message should I look for in the logs?

jopasserat (Wed, 30 Oct 2019 15:29:04 GMT):
i assume it's registered since i don't get the same error than when submitting an invalid workload id

jopasserat (Wed, 30 Oct 2019 15:36:11 GMT):
once submitted i get an error 5 from the generic client

jopasserat (Wed, 30 Oct 2019 15:36:24 GMT):
"Work order is computing. Please query for WorkOrderGetResult to view the result"

jopasserat (Wed, 30 Oct 2019 15:36:32 GMT):
and the TCF log loops on the same message

manojgop (Wed, 30 Oct 2019 17:18:55 GMT):
That's normal operation. Currently only pull model is implemented by TCF. Client is expected to call WorkOrderGetResult periodically to get result of work order.

jopasserat (Wed, 30 Oct 2019 17:25:08 GMT):
how do I know it's actually doing something? my workload is pretty light (similar to the heart evaluation) and I had left the client query for > 5 mins without getting the results back

jopasserat (Wed, 30 Oct 2019 23:58:53 GMT):
update: workload registered and started (commented out most of the logic to replace by the equivalent of an echo)

jopasserat (Wed, 30 Oct 2019 23:59:14 GMT):
=> there's something behaving differently in and out TCF in my C++ code

jopasserat (Thu, 31 Oct 2019 00:00:00 GMT):

hello , I have a question

ferrarifei (Thu, 31 Oct 2019 08:15:40 GMT):
How can I create a trusted execution environment(TEE) with the SGX

ferrarifei (Thu, 31 Oct 2019 08:15:55 GMT):
I mean that in the TCF

@ferrarifei Start with the examples and tutorial at https://github.com/hyperledger/avalon/tree/master/docs#tutorial

jopasserat (Thu, 31 Oct 2019 19:31:17 GMT):
fixed the issue in my code => everything runs smooth

jopasserat (Thu, 31 Oct 2019 19:31:48 GMT):
question still remains of: is there a way to get more info about an execution?

jopasserat (Thu, 31 Oct 2019 19:32:04 GMT):
only clue i had here was this `core` file that suggested a crash at runtime

danintel (Thu, 31 Oct 2019 21:57:02 GMT):
@jopasserat `export TCF_DEBUG_BUILD=1` might help. See https://github.com/hyperledger/avalon/blob/master/PREREQUISITES.md#environment Also look at the Avalon Listener and Enclave Manager log output.

jopasserat (Fri, 01 Nov 2019 10:18:33 GMT):
where shall i find the Avalon Listener and Enclave Manager log output? separate files (couldn't find where they'd be stored)? or part of the docker-compose tcf log on the console?

danintel (Fri, 01 Nov 2019 14:59:28 GMT):
@jopasserat The output goes to the terminal. It can be redirected to a file if needed.

danintel (Fri, 01 Nov 2019 15:00:18 GMT):
@ferrarifei The technical details of Intel SGX enclaves are encapsulated in the Avalon libraries and Avalon Enclave Manager.

danintel (Fri, 01 Nov 2019 15:00:18 GMT):
@ferrarifei The technical details of Intel SGX enclaves are encapsulated in the Avalon libraries and Avalon Enclave Manager. If you want to learn about low-level details, I would look at the Intel SGX SDK and example programs.

jopasserat (Fri, 01 Nov 2019 16:20:36 GMT):
ok thanks @danintel i guess the crash was too "sudden" in my case to see anything interesting in logs

ferrarifei (Mon, 04 Nov 2019 13:16:45 GMT):
Is there any more information about what is in the picture, I wonder how the SGX guarantees integrity for code and integrity and confidentiality for data

ferrarifei (Mon, 04 Nov 2019 13:20:01 GMT):
What's the relationship between workload and worker？

ferrarifei (Mon, 04 Nov 2019 13:20:13 GMT):
I know sgx applications are divided into two parts，app and enclave(trusted and untrusted),If I want to run my application to the SGX TEE, Do I need to modify it to two parts?

arsulegai (Mon, 04 Nov 2019 13:24:29 GMT):
@ferrarifei I will try to answer you in simpler words

arsulegai (Mon, 04 Nov 2019 13:25:10 GMT):
Please read about remote attestation, how the quote from the device is sent and verified remotely is the key to integrity protection of your application

arsulegai (Mon, 04 Nov 2019 13:25:57 GMT):
Workload - Your business logic, Worker - A framework component which distributes work to the workloads.. At high level

arsulegai (Mon, 04 Nov 2019 13:28:16 GMT):
Ideally you need to design your application such that the core business part resides in the enclave, ensuring that even if your untrusted part is compromised the trusted part cannot be. But please refer to an example application in the https://github.com/hyperledger/avalon , it is easy to understand and well documented.

ferrarifei (Mon, 04 Nov 2019 13:35:20 GMT):
Ok，thank you

must I use C++ to write application as a workload?

Sun0216 (Mon, 04 Nov 2019 14:17:01 GMT):
What is the purpose of using docker, and what does it have to do with SGX? I mean, are enclaves running in containers?

jopasserat (Mon, 04 Nov 2019 14:25:40 GMT):
TLDR: same algorithm, different params. Eth adopted keccak-256 before it got standardised with a different set of parameters under the name SHA3 https://ethereum.stackexchange.com/a/554/23688

jopasserat (Mon, 04 Nov 2019 17:39:52 GMT):
with regards to @Sun0216 's question :point_up: : from the current state of the repo it seems workloads are C++ only for the moment correct? How far are we from having the possibility to implement workloads using other programming environments / Docker images in Avalon?

danintel (Mon, 04 Nov 2019 18:52:49 GMT):
Ethereum purposely calls it Keccak for that reason. It still causes confusion because sometimes Keecak refers to the official SHA-3 in non-Ethereum contexts (such as the OpenSSL library)

danintel (Mon, 04 Nov 2019 18:54:52 GMT):
@jopasserat Yes, workload implementations are only in C++ for now. There was a PR to add a Java workload, but it has appeared and disappeared twice.

danintel (Mon, 04 Nov 2019 18:58:20 GMT):
@Sun0216 *Language support:* For now only C++ is supported for workers. However, any other language can be added. There was a PR to add Java, for example.

danintel (Mon, 04 Nov 2019 18:59:22 GMT):
@Sun0216 Docker is used only as a convenience. It has nothing to do with the Avalon security model or enclaves. Docker makes it easier to build and setup Avalon, but you can also build without Docker (although it requires several more steps)

danintel (Mon, 04 Nov 2019 18:59:22 GMT):

danintel (Mon, 04 Nov 2019 19:08:10 GMT):
Intel SGX enclaves can be thought of as a "reverse sandbox". A traditional sandbox restricts the software from accessing system or external resources on a machine (such as a Java VM). A SGX "reverse sandbox" or enclave keeps the system--other applications and even root--from accessing data inside the enclave. The PDF link at this webpage gives a good technical overview of Intel SGX enclaves: https://software.intel.com/en-us/blogs/2016/06/06/overview-of-intel-software-guard-extension-enclave

danintel (Mon, 04 Nov 2019 19:17:00 GMT):
@ferrarifei *Avalon libraries* are provided in source form from https://github.com/hyperledger/avalon/ and must be compiled. The enclave libraries are in subdirectory tc/sgx/ Client libraries are under examples/common with example client applications under examples/apps/ > where are the Avalon libraries

jopasserat (Mon, 04 Nov 2019 22:09:26 GMT):
i was more thinking of accepting workloads from Docker images the way iExec permits. isn't it on the roadmap? that's what I assumed from the reference to " native applications" in the wiki

danintel (Mon, 04 Nov 2019 22:12:33 GMT):
Sorry, I don't know about iExec's use of Docker.

jopasserat (Mon, 04 Nov 2019 22:14:02 GMT):
they support the execution of docker containers in SGX enclaves via Scone: https://docs.iex.ec/buildsgxapp.html#creating-a-sgx-dapp

Tcf will listen on port 1947 and currently in docker mode either you have to get into tcf container to use it or you can do port mapping in tcf container to use outside the container.

hi @EugeneYYY @rranjan3 do we want to make a decision on where to save the workshop resources? (demo keys and configs for besu target, docker-compose.yaml, truffle-config etc.)

jimthematrix (Thu, 06 Feb 2020 22:01:32 GMT):
easiest is to have a "local" folder as a self-contained place to build a local test environment (as we did for DevCon)

jimthematrix (Thu, 06 Feb 2020 22:02:15 GMT):
it can have "besu", "fabric" subfolders to launch respective target blockchains

EugeneYYY (Thu, 06 Feb 2020 22:03:03 GMT):
You are talking about folders within VB VM (vs. in GITHUB repo), right? Then, it makes sense to me

Dan (Thu, 12 Mar 2020 19:21:40 GMT):
is there a trick when we map environment variables into a container? My container seems to understand the proxy as network traffic works but if I try to read the proxy environment variables themselves they are empty. In container ``` $ env SGX_SSL=/opt/intel/sgxssl SGX_SDK=/opt/intel/sgxsdk TCF_HOME=/project/TrustedComputeFramework https_proxy= http_proxy= ``` Docker Definition: ``` ENV http_proxy=$http_proxy ENV https_proxy=$https_proxy ENV TCF_HOME=/project/TrustedComputeFramework ENV SGX_SSL=/opt/intel/sgxssl ENV SGX_SDK=/opt/intel/sgxsdk ```

Dan (Thu, 12 Mar 2020 19:21:59 GMT):
on the physical host those proxy values are set

Dan (Thu, 12 Mar 2020 23:15:26 GMT):
so I think (but don't know) that the dockerfile only considers environment variables passed to it through the `--build-arg` flags. The ENV items defined inthe image can later be overwritten using the `-e` flag on the `docker run` command line. This doesn't come up in the avalon dockers because they are mostly launched with `compose` and the compose file essentially does what these command line flags to `docker build` and `docker run` do.

rranjan3 (Sat, 14 Mar 2020 05:22:30 GMT):
What image do you use in this case @Dan ? Even in a vanilla bionic container, you should see several variables for `env`

rranjan3 (Sat, 14 Mar 2020 05:48:14 GMT):
`$http_proxy` in your docker definition would be a variable in context at build time. To give it a value, you either use `--build-arg` or if using compose, add `args` under `build` as - ` build: context: ./ dockerfile: ./DOCKER args: http_proxy: $http_proxy ` Then declare in the Docker definition as - `ARG http_proxy` // Needed when setting via compose. Not sure if that is the case for `--build-arg`

@Dan `$http_proxy` in your docker definition would be a variable in context at build time(you cannot read environment variable directly here). To give it a value, you either use `--build-arg` or if using compose, add `args` under `build` as - ``` build: context: ./ dockerfile: ./DOCKER args: http_proxy: $http_proxy ``` Then declare in the Docker definition as - ```ARG http_proxy # Needed when setting via compose.

rranjan3 (Sat, 14 Mar 2020 05:49:44 GMT):
However if using compose, the best way would be - ``` environment: - http_proxy ```

rranjan3 (Sat, 14 Mar 2020 05:49:44 GMT):
However if using compose, the best way would be - ``` environment: - http_proxy ``` This would read your envt variable on host and set it within container. Yet another way to pass proxies is through a config json - https://docs.docker.com/network/proxy/ But the latter 2 are for runtime of the container. Build time still might require the first approach.

rranjan3 (Sat, 14 Mar 2020 05:49:44 GMT):

Dan (Mon, 16 Mar 2020 20:27:31 GMT):
thanks. I think what happened was I am using a dockerfile that was designed to be run from compose where those things would get set.

Hi Avalon enthusiasts, The topic for the upcoming session on 03/24/2020 is DCAP presentation By Dan Middleton (Intel) Details: We will look at how to use datacenter attestation primitives. This attestation flow enables more distributed communication patterns than what we have today. The added flexibility also means there are a lot of possible paths to choose which can seem confusing. In order to get started we have created a lab that chooses one concrete path. https://github.com/hyperledger-labs/dancap We will start by explaining attestation and then use the lab to demonstrate creating an attestation at one CSP and then verifying it in a (virtual) on-prem datacenter. Regards Harsha

jopasserat (Tue, 07 Jul 2020 18:00:52 GMT):
Hi team! i'm trying to better understand what can and cannot be done with the workloads at the moment. Two questions: - the architecture overview document suggests workloads can be expressed not only in C++ but also in Rust when pre-compiled at build time. would that imply embedding the whole Rust toolchain in the build? or would i be able to deploy a binary/library compiled against the SGX SDK outside Avalon and call it as part of the workload (while still respecting the plug-in API of course)? - i've seen C++11 flags being manually specified all over the Cmakelists for the workloads. Is the framework restricted to C++11 for now? thanks a lot for your help :)

danintel (Tue, 07 Jul 2020 21:27:06 GMT):
@jopasserat The idea is to support other languages for the worker, but that's not there yet. Only C++ is supported now.

danintel (Tue, 07 Jul 2020 21:29:50 GMT):
Your C++ binary could call other languages, but that's not how it's designed to work. The worker executes inside a Trusted Execution Environment (TEE), currently Intel SGX. Having the worker execute code outside the TEE defeats the purpose of Avalon.

jopasserat (Tue, 07 Jul 2020 21:49:57 GMT):
yes yes of course, i was interested in the ability to bring other elements as part of a single workload running within the same TEE

MujtabaIdrees (Thu, 06 Aug 2020 04:58:22 GMT):
Hi, I am trying to understand Hyperledger Avalon. For now, I have been able to execute workloads from 'examples/apps/'. However, I have a few questions. 1. How are these workloads sent to the work order processing enclave? As I understand currently these workloads are compiled in dockerfile and added to the enclave while it is being initialized. The clients then send the workload id to be processed. Please verify if my understanding is correct? 2. Let's say I have to add a new workload in already running network, how would I do that?

danintel (Thu, 06 Aug 2020 18:03:48 GMT):
1. The workloads are sent using JSON RPC (Direct model) or with the blockchain connector event handler (Proxy model) 2. You can write your own requester (client) to submit workloads or use the generic client under `./examples/apps/generic_client/` that comes with Avalon (the latter is good for rapid prototyping).

MuhammadUsamaSardar (Thu, 06 Aug 2020 18:10:40 GMT):
Will slides of today's session be shared? The insurance company example was interesting. Are the details documented somewhere for further understanding?

It seems like there is interest in this content, so if anyone from the Avalon project would like to present at any other meetups in the future please let me know.

MujtabaIdrees (Thu, 06 Aug 2020 23:56:09 GMT):
Do we have any tutorials/documentation on how to write custom workload client? Or any leads on how to submit a custom workload using generic_client?

danintel (Fri, 07 Aug 2020 01:09:44 GMT):
No. It is simole though. Look at and modify the generic client.

danintel (Fri, 07 Aug 2020 01:09:44 GMT):
No. It is simple though. Look at and modify the generic client.

MujtabaIdrees (Sat, 08 Aug 2020 00:30:54 GMT):
Thank you for your response, following your tutorial at https://github.com/hyperledger/avalon/tree/master/docs/workload-tutorial and its corresponding video, I now understand how a new workload can be added in Avalon. Now, I have the following questions: 1. All worker nodes (wpe) need to build workloads inside the enclave, before it is initialized. A worker can only process those workloads which have been added in its enclave before measurement. Please verify if my understanding is correct? 2. Can a worker node(wpe) have multiple enclaves running inside? If yes then how can I configure it?

Hi, I have a question. I'm trying to get Avalon to work on multiple VMs (VM1 and VM2) with Fabric blockchain network. VM1 have fabric network (created by minifab) and avalon-pool (worker name is kme-worker-1). VM2 have only avalon-pool (worker name is kme-workeer-2). Next I want to run generic_client from VM1's avalone-shell with specified kme-worker-2. I ran the following command on VM1. ```shell cd $TCF_HOME ./scripts/start_fabric.sh -u -e sudo docker-compose -f docker-compose.yaml -f docker/compose/avalon-pool.yaml -f docker/compose/avalon-fabric.yaml up -d --build scp -r $TCF_HOME @:~/ ``` I ran the following command on VM2. ```shell cd $TCF_HOME vi config/kme_config.toml # :%s/kme-worker-1/kme-worker-2/g vi config/wpe_config.toml # :%s/kme-worker-1/kme-worker-2/g sudo docker-compose -f docker-compose.yaml -f docker/compose/avalon-pool.yaml -f docker/compose/avalon-fabric.yaml up -d --build ``` After that, I try ran `docker exec -it avalon-shell bash`. Next, I try ran `examples/apps/generic_client/generic_client.py -b fabric --workload_id "echo-result" --in_data "Hello" -o --worker_id "kme-worker-2"` in VM1. But I get following error messages... 2020-11-06 09:46:25,863 - ERROR - Worker is not active 2020-11-06 09:46:25,863 - ERROR - Unable to retrieve worker details Am I following the right procedure? And, Is the configuration I'm trying to build feasible?

Dear Avalon enthusiasts, We have recently concluded a project with the collaboration of T-Systems and TU-Dresden in which we have forked Hyperledger Avalon and enabled it to run with SCONE trusted compute workers. Please find the whitepaper and feel free to explore our git (https://github.com/T-Systems-MMS/hyperledger-avalon-scone).

@HarshaIntel what timezone should the Avalon call use? The current one (Pacific/Midway) is invalid.

Hi!! I'm new to Avalon. I'm building a Hyperledger Fabric based application. There I have few offchain applications running some machine learning algorithms. Can I use Avalon to orchestrate this application ? Is is yet possible to run worker programs in a form of a docker container without implementing the workers from the scratch ? Sorry for my dumb questions.

tharindupr (Wed, 25 Aug 2021 19:41:48 GMT):
For anyone interested I found this Avalon + Scone integration which provides a docker based worker implementation : https://github.com/T-Systems-MMS/hyperledger-avalon-scone

tharindupr (Wed, 25 Aug 2021 19:43:07 GMT):
Great work. This is the exactly I was looking for. Thanks

The Hyperledger Technical Steering Committee recently created a Chat Task Force to look into what could be done to improve the experience of using the community's chat tool. For reference, more about the Task Force is at: https://wiki.hyperledger.org/display/TF/Hyperledger+Community+Chat+Taskforce I wanted to get your input so that the Task Force has feedback from Hyperledger Avalon community as they make decisions about what, if anything, to change. If you would like to have a discussion about this, please let me know and we can set up time to talk. Or if you would prefer to write down your thoughts, that would work too -- you can see the questions the Task Force has at the page at: https://wiki.hyperledger.org/display/TF/Community+Chat+Interview+Questions
