  • https://github.com/decentralized-identity/peer-did-method-spec/pull/55
  • Discover Features did method, stretched to did:peer:3?
• Aries RFCs – PR reviews:
  • Unqualified to Qualified DID Community Coordinated Update
    • Issues for transforming unqualified DIDs to DIDDoc 3:
      • What should the DIDComm Messaging "type" be?  "IndyAgent", "did-communications", "DIDCommMessaging"?
        • Differentiate with Type between v1 and v2
        • needs research to do the right thing.
  • Goal Codes for simulated Connection-less Presentations
  • AIP 2.0 Clarifications
• eIDAS 2.0 / EUDI / ARF Common goals?
  • Work already underway
    • Animo / AFJ: https://animo.id/project/making-aries-framework-javascript-a-global-framework
    • AF-GO: SD-JWTs under way (PRs)
    • ACA-Py
      • OpenID4VCI/VP support being explored. Adding a companion service may be best option. Plugin option is like a companion service but more tightly integrated.
      • SD-JWT crypto not too bad, good libraries exist (lighter lift than OpenID4VP protocols)
      • Adding format definitions for these credentials over the existing DIDComm protocols is separate work.
  • Work that needs doing:
    • Askar: support for HSM based keys
      • Theorized as Possible
      • Needs investigation
      • RUST based
  • Notes:
    • SD-JWTs and mDOCs may use the same underlying technique for selective disclosure
    • Anoncreds has an in with W3C format alongside LD creds (Type 2) with the translation that has been defined, but not built.
    • DIDComm has a similar onramp by demonstrating compatibility with the listed credential formats.
    • AnonCredsRS to absorb the W3C data model translation? - Yes. Existing python isn't too complicated - would need to be adapted into the AnonCredsRS Library.
• Open Discussion
  • RFCs to DIF?
    • Confusion on source of truth?
    • If left in place, linking to the right source of truth is important to avoid confusion.
