Agenda

• Milestone 0.7.5 – progress and anything more to add to it?
• AnonCreds discussions from Hyperledger Global Forum and Rebooting Web of Trust
  • AnonCreds as a top level project – presentation and draft proposal – please consider being a sponsor (name, optional organization, email address)
  • AnonCreds ledger agnostic
    • Up to 6 non-Indy AnonCreds implementations found
    • Progress on AnonCreds Spec – more contributors
    • Working right now on AnonCreds API with AnonCreds Methods
      • AnonCreds spec defines the format produced on creation and/or expected for use of: Schema, CredDef, RevRegDef, RevRegEntry
      • AnonCreds Methods must provide the objects in the expected format.
      • Mostly straight-forward, but interesting for RevRegEntry, where AnonCreds Methods may store the data as deltas or as full state.
  • AnonCreds in W3C Verifiable Credential Data Model Format
    • It seems to be really easy...
  • Likely path forward:
    • Code: Extract AnonCreds from indy-shared-rs
    • Code: Define AnonCreds – AnonCreds Method API
    • Code: Implement AnonCreds Methods – indy legacy, did:indy, perhaps HTTP, cheqd
    • Code: AnonCreds in W3C Format – transformations
    • Top Level AnonCreds Project
    • New AnonCreds Revocation
    • Next Gen AnonCreds with (at least) the same features, but better, faster
• Discussion of PR 1956 - Combining credentials in Present Proof v2
• Discussion on recently merged PRs, open PRs and issues
  • GitHub Actions and publishing artifacts - Daniel Bluhm
• Open Discussion
• Q&A
