Welcome / Introductions

Announcements

...

• Aries WG
  • Presented a comparison of did:keri (lite) and did:peer (algo2... algo1 is used in AFJ)
  • Need to do pros/cons spreadsheet comparing the priorities/reqs/community needs
• Aries Agent Test Harness (https://aries-interop.info)
• Aries Askar secure storage - https://github.com/bcgov/aries-askar
• Frameworks:
  • Aries-CloudAgent-Python (https://github.com/hyperledger/aries-cloudagent-python, Meetings: ACA-Pug Meetings)
    • Encryption envelope (Askar impl) not fully-developed yet. We could use different libraries (SICPA Rust). SICPA DIDComm impl is what will be used... resolves did peers natively. The keys will have to be transported out of Askar, but that is acceptable for now. SICPA is the most widely used.
      • SICPA for DIDComm and did:peer https://github.com/sicpa-dlab/didcomm-python
      • No near-term Askar support for the DIDComm v2 encryption envelope and core protocols.
    • Protocols related to credential exchange and connection establishment. Distinguish between DIDComm v1 and v2. DID Exchange will be adapted.  The main focus is on Out-of-Band protocol.
    • Very important to extend the AATH.
  • Aries-Framework-JavaScript (https://github.com/hyperledger/aries-framework-javascript, Meetings: Framework JS Meetings)
    • https://github.com/hyperledger/aries-framework-javascript/pull/1096#issuecomment-1343833016
    • https://github.com/hyperledger/aries-framework-javascript/pull/1211
    • Issue related to multi-base from SICPA for DID peer
  • Picos as Aries agents (DIDComm v1: https://github.com/Picolab/aries-cloudagent-pico ; DIDComm v2 work in progress)
    • students have returned and they are using SICPA for envelope encryption, pack/unpack and hopeful sending messages
    • DIF Picos working group, useful for IoT devices.
    • Rich API and Internet connected to be a capable L2 agent.
    • Using Trinsic as VC as a service.
  • Swift Framework
  • Veramo Framework
    • WACI support https://github.com/uport-project/veramo/issues/1106
    • DID Peer support https://github.com/uport-project/veramo/issues/1105
      • Using Brian's (AviaryTech) DID Peer impl, adapting it as a plugin
        • PR submitted and in review https://github.com/roots-id/didpeer-plugin
    • Merged Mediation, agent can mediate. A Veramo mediator will be published soon.
• Mobile:
  • Aries Mobile Agent React Native, aka Aries Bifold (https://github.com/hyperledger/aries-mobile-agent-react-native, Meetings: Aries Bifold User Group Meetings)
• aries-mediator-service – a DIDComm Mediator in a Box
  • working on Pickup support
  • DIDComm v2 support would probably originate from this meeting/community
• AviaryTech DIDComm TS impl
  • https://github.com/aviarytech/didcomm
  • https://github.com/aviarytech/did-peer
  • Focused on OIDC lately
• KERI Working Group
  • Alternative to peer DID.  More refinements to the proposal. Then present it to the Aries groups.  Similar to Algo2 of the peer DID.
    • KERI parameter on the DID in order to get the document. Public encryption key and serviceEndpoint.
    • Query param w/ base 64 path that you can decode
      • encryption keys, service endpoint, etc.
      • Compared to did:peer, the keri long form is longer
        • inception event only
        • But follow-on messages only need to use the short-form of KERI DID
      • So, this is not a Persistent did
    • Rodolfo Miranda Will add a README and sample output.
• ToIP Trust Spanning Protocol
  • Good back and forth between Sam, Daniel, and others https://github.com/trustoverip/trust-spanning-protocol/discussions/17
  • Daniel present his proposal this week, at the Wednesday TSPTF
  • Sam joins the task force and has a video of Sam's that diagrams his TSP vision https://zoom.us/rec/play/1EcHtXeGPPynwwBvU3X4uAAw0xhFPC3CwwAIXwQ-P_E6tPlzvBskHuzTYftS1ZrmjPw5EiBZWYwiTgdI.tx021j9JATi2l5Xq?continueMode=true&_x_zm_rtaid=noVlj_2fRpuccKG26Jmytw.1675686252575.5cf45b925f44c52d0118a3fdef8541ea&_x_zm_rhtaid=714

Nessus DID Peer 2 journey

• OOB with a 'public' did document that anyone can use. Chicken and the egg for Root-of-trust.
  • Start with a trust ping.
  • Request a credential? For extra validation.
• SICPA did peer Java PRs have brought it to usable place 
• Demo in two weeks
  • OPA verification policies
  • W3C JSON-LD and JWT
    • We will check with Alex Andrei to see if we can accept an issued credential from Thomas Diesler 
  • Technology Compatibility Kit (TCK) in java provides compliance for J2EE, similar concept to AIP
    • This is a large market for licensing in the java world
    • DIDComm could have a similar
  • Reference implementation
    • First or most complete Agent that passes the TCK
  • Can DIF own the TCK?
    • Create a test harness similar to what Fabio Pinheiro is asking for in DIDComm v2
• IBM w/ DIF?

April 2023 IIW DIDComm v2 interop

• How can we get the word out?j
  • Lance Byrd posted on Discord https://discord.com/channels/905194001349627914/1032736844053483621/1082338707597697055
• Receive a credential over OIDC (OIDC4VC) and present proof with DIDComm
  • Who in the OIDC to connect with? Also, connect with Sam. Ask Drummond.
  • Walt.id supports OIDC 
• Which agents might participate:
  • AFJ
    • Ariel Gentile 
    • Animo?
  • Veramo
    • Nick
    • Cody
  • BlockTrust
    • Björn Sandmann 
  • AviaryTech
    • Brian Richter 
  • Indicio
    • Alexandra Walker Sam Curren 
  • PicoAgents
    • bruce_conrad@byu.edu
  • RootsID
    • RootsWallet
  • Atala Prism
    • Alex Andrei Rodolfo Miranda 
    • Anyone from Atala team attending?
  • Nessus
    • Thomas Diesler might be a recording
• What protocols do we want to highlight/use
  • Basic Message
  • Trust Ping
  • Mediation
  • Issue Credential
    • This is more complex, which format, etc.
  • Verification
  • Schema Validation
• Pre-record video showing the interop between them
  • For the session it needs to be very scripted so that everyone is successful
    • Group chat? New protocol, maybe in Fall IIW?
• Veramo agent as a test harness for DIDComm?
• BlockTrust is implementing mediator, etc and will be at IIW
  • No usable .NET lib, had to write it from scratch
    • Crypto is especially challenging
  • Reference implementations help a lot
    • SICPA libs continue to gain adoption and are nice for reference
