Welcome / Introductions


  • IIW - April 16-18
  • There had been a number of BCovrin (dev, test, greenlight, etc.) Indy ledgers, all now point to BCovrin Test (e.g. genesis files all point to the same ledger).
    • BCovrin Test is the one that many Mobile Wallets use for testing. It will remain available indefinitely.

Release Status and Work Updates

Discussion Topics

  • Aries RFC MkDocs Demo and Feedback - Stephen

        • propose message moves to different family.
      • Document the short-circuted use of the protocol that starts at issuance directly, depending on needs of credential type.
      • we need to be careful not to match protocol to UX human steps on a 1 to 1 basis
      • abandoned state - if a user declines to present, what should happen between the holder and verifier?
        • problem report sent (or no message, see below) on decline - should be documented
      • explicit 'no' messages instead of a problem report when it's an explicit no, instead of an error.
      • document use of timeout for offers (didcomm v2 friendly, perhaps a field within the protocol.Credential Protocols for DIDComm v2
    • Any Volunteers?
  • Basis for common identifiers
