Agenda

• DID Registration

  • Making it easier to add/use a range of DID methods, including for AnonCreds – did:key, did:jwt, did:peer, Cheqd, Hedera, did:tdw, did:web, did:sov, did:indy or Indy on Besu ledgers

  • Existing reference material:

    • Recap of design discussion at IIW – presentation - https://docs.google.com/presentation/d/1Mee4oZlQPUVkOSrMTNRl8ELGUKLyhDDw8FSpTP_-wkQ/edit?usp=sharing

    • DID Registration API from DIF – spec - DID Registration

    • PR from Cheqd with their current approach - https://github.com/cheqd/aries-cloudagent-python/pull/1

    • HackMD document from Jamie ...that builds off this HackMD document from Daniel: https://hackmd.io/sk-86TsSTUefYA2J0rjuGQ

  • Architecture as envisioned by the Cheqd devs:

• Transition to OWF – mostly complete

  • #3250 steps complete

  • Need to document how to update an installation to use OWF artifacts vs. Hyperledger

    • Name and location of images/artifacts

    • Anything in the code that has to change as a result of the module name change?

      • A little bit needs to change.

        • Plugins need to do a find replacement for the name change.

        • If you are just interacting with the Admin interface – no change.

        • Configuration unchanged between 1.0.1 and 1.1.0.

  • Last week – transferred the related repos. Documentation updates needed in those repos.

• PRs:

  • Failing tests – biggest concern – thoughts?

    • Not a general issue.

  • Ready for review/approval/merging:

    • Dependabot – today – the debugpy one? OK

    • #3208 – pagination support. Just update – ready for review

    • #3279 – Verification Selection by DID – approved / ready to go.

    • #3331 – Updating the AnonCreds issueance and presentation formats – cleanup

  • #3312 needs a review – volunteers? Done and Merged

  • DIDComm v2 Progress for the Interopathon

    • Enough support (with some corner cutting) to be ready for the interopathon.

      • Basic Protocols – trustping, basicmessage, Mediator integration, DID Rotation.

      • Enables iterating on the support to add the more complex protocols.

      • Notes:

        • Decrypt, deserialize the message and use the message type to route to a handler.

        • Inverting – type to pick the handler, then deserialize in the handler. This is common in most Web Frameworks.

          • Question: Does the existing approach help with security. It’s fine because there is a middleware handler in ACA-Py that takes care of that.

          • Question: What about decorators? In DIDComm v2, decorators are in the message headers, and the headers are handled by the “middleware” in ACA-Py before the handler.

  • #3253 – did:indy update and discussion around the concept of Public DID.

  • #3332 – Trace logging - some question as to whether it works/doesn’t work…

    • Goal to get to loguru for logging

• Issues:

  • #3321 – sending a VP without a request?

Plugins

• Issue resolved in OID4VC Plugin: OpenID4VP SD-JWT is not verifying the holder signature (KB-JWT) · Issue #1163 · openwallet-foundation/acapy-plugins
