Notes:

Discussion Topics

• AIP 2.0 Update (https://github.com/hyperledger/aries-rfcs/pull/739)

• Device Binding Attachments (https://github.com/hyperledger/aries-rfcs/pull/729)

• Open Discussion

  • Indy Revocation Support

    • Registry got out of sync between ledger and wallet, updates no longer possible.

    • TAA Handing prevented writes

    • those writes were registry updates

    • the resulting out of sync state prevented the registry from being updated.

    • Ian added code in ACA-Py to allow 'fixing' a registry - pulling ledger state into ACA-Py, then re-applying the revocations and writing to the ledger.

  • New Revocation Scheme

    • Andrew's new mechanism avoids the same issue - whole registry written (efficiently) each time.

    • Needs:

      • Implementation,

      • review of used crypto to find weaknesses

      • ledger update for registry publishing

      • Binding between presentation and proof of non-revocation

      • Cam with Kiva can help within Ursa

    • Need a Champion to move this forward within Ursa

  • Paul Bastian - new method for binding

    • Certifying entity

    • Wallet authentication VC

Other Business

Future Topics

• Apache Camel Demo - Thomas from Redhat

• decorator for redirection after proofs. - existing?

• Standardized attribute names for AnonCreds - alignment with VC data model. (Paul Bastian)

  • terms and conditions (as link)

  • machine-readable governance?
