• Full Meeting: <to be added> dummyfile.txt
• Extracted segments:  Discussion on DIDs, DID Methods, AnonCreds Objects and Ledger Agnostic ACA-Py starts at 9:49 of the recording.
• Relevant Chat Bits:
  • 08:22:51 From Victor Martinez (SICPA) : https://docs.godiddy.com/en/advanced/didcomm-interface
  • 08:25:42 From Timo Glastra : We recently added a generic did resolver to AFJ. There is a spec from the identity foundation for a generic did registrar interface: https://identity.foundation/did-registration/
  • 08:27:27 From Victor Martinez (SICPA) : https://github.com/sicpa-dlab/aries-cloudagent-python/tree/feature/did-registrar
  • 08:40:30 From Timo Glastra : Cheqd identifier example: did:cheqd:mainnet:6h7fjuw37gbf9ioty633bnd7thf65hs1/resources/f09c9296-6b39-4057-afff-dc2116fe746d
  • 08:42:39 From Timo Glastra : The appraoch we're taking for AFJ is creating a generic AnonCredsResourceService. You pass it an id and it resolves to the AnonCreds objects. The ID should be unique enough to determine the specific resource + define the resource provider (e.g. indy, cheqd, but could also be https).
  • 08:43:32 From Timo Glastra : Someone made a fabric integration in AFJ that swapped out the Indy ledger service for a fabric ledger service, and it kinda worked with the indy sdk out of the box
  • 08:45:13 From Timo Glastra : You can define it as a cred def / schema in your did document by adding a service:

  • 08:45:19 From Timo Glastra :

Announcements

Deployments and Work Updates

...

• Updates on merges and current PRs – priorities
  • Merges Since 0.7.4
  • Open PRs
• Discussion: How to enable object (DID and AnonCreds) resolution to improve ledger agnostic Aries protocols, and in particular, ledger-agnostic AnonCreds
  • Topics:
    • DID Resolution:
      • State of DID Resolution in ACA-Py – local and external resolvers, regex to define if and how to resolve a DID.
        • External resolvers – http and didcomm interfaces available
      • Work happening now on did:peer to make it fit the interface
      • Working happening at SICPA on a DID Registrar based on the DIF Spec - Issue to be added to discuss/track
        • EBSI plugin being created (Ethereum based, DIDs only)
        • Plugins needed for did:sov, did:indy, did:peer, did:key  and folks may be interested in adding more
      • Inconsistency in returned DIDDoc – suggests the need for a method in ACA-Py to "smooth out" the handling of DIDDocs - Issue to be added to request
    • AnonCreds Objects Handling
      • Currently tied to Indy – a "baseLedger" class with instances for Indy-SDK (indy-wallet storage only) and Indy VDR (indy-wallet or askar storage).
        • Handles writing as well, with Endorser handling.
      • Likely need to abstract to a similar, pluggable resolution and writing mechanisms - Issue(s) to be created.
        • Given an identifier in an AnonCreds object/context – resolve it.
        • Write AnonCreds objects using plugins to various target VDRs.
      • AFJ starting to talking about an AnonCredsResourceService
