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)
