Cred Def 2.0, Revocation Registry 2.0


Dependency preventing Ubuntu 18.04?  Bounty?

HIPEs, Aries-RFCs, Ursa-RFCs, Sovrin SIPs, docs folders

(How do we manage the multiple locations)


  • Indy-SDK-lang repositories created as Aries-SDK-lang repos:
    • aries-sdk-python: Sam Curren (telegramsam), Andrew Whitehead (cywolf)

    • aries-sdk-ruby: John Callahan (johncallahan)

    • aries-sdk-go: Arjan Van Eersel (arjanvaneersel)

    • aries-sdk-ios (Objective-C and Swift): Steve McCown (smccown)

    • aries-sdk-android: Mike Lodder (mikelodder7)

    • aries-sdk-dotnet: Tomislav Markovski (tmarkovski), Thomas Shelton (twshelton)

    • Needed:

      • aries-sdk-java: maintainer(s)

      • aries-sdk-android: co-maintainer

      • aries-sdk-ios: co-maintainer

      • aries-sdk-javascript (Node and client side JS): Joe Genereux (thedolie)? Kyle's friend?

  • Also: aries-sdk: Sergey Minaev (jovfer), Artem Ivanov (Artemkaaas), Sam Curren (telegramsam)

  • Reception of Aries project
    • Generally positive.
    • Concerns from DIF crew about Aries being in Hyperledger.
      • Want as large a contributor community as possible
      • But don't want to slow down forward progress with governance questions
      • Create an Aries DIDComm working group might help DIF participants?
        • Probably won't help.
  • Timeline for Indy migration to Aries.
    • Future of LibVCX? Will be discussed in the Indy SDK WG on Wednesday.
    • Indy SDK vs Aries SDK? Will be discussed in the Indy SDK WG on Wednesday.
    • Indy Agent Test Framework becomes Aries DIDComm Test Framework
      • DIDComm or DIDComms ? Will decide in the Aries call.
  • Cred Def and Revocation Registry 2.0
    • Does the Issuer decide how an attribute is encoded to a cryptographic value?
      • Anoncreds 1.0: If it is a number, take it. If not, sign the SHA256.
      • Anoncreds 2.0: Needs to work with Schema 2.0 (attribute mapping to the cryptographic integer that gets signed)
      • Allowing every Issuer to do something different reduces the reusability of the schema.
        • But issuers might have different standards for things.
        • But an issuer can always create a new schema.
    • How quickly can we deprecate the current approach in favor of the new approach?
      • Need a detailed architectural review before making a decision.
  • Documentation:
    • Need a SIP for Transaction Author Agreement explaining policy needs.
    • Need better documentation for Indy Node.
      • Evernym video:

Next Week

  • Documentation: (a conversation for the US / Europe group, already had it with US / Asia)
    • Where to document changes? HIPEs/Repo Docs/Jira Tickets
    • PR's should link back to Jira tickets
