Welcome and Introductions

• Status Update – ACA-Py 0.7.0 Release – Andrew Whitehead
  • ACA-Py 0.7.0RC0 has been tagged
  • List of major updates and additions:
    • Support for W3C Standard Verifiable Credentials based on JSON-LD using LD-Signatures and BBS+ Signatures
    • Support for DIF Presentation Exchange
    • Present Proof V2 Support
    • Pluggable DID Resolver (with a did:web resolver) with fallback to an optional/configurable external DID universal resolver
    • Endorser Signing Transactions Protocol
    • Upgrades to Demos to add support for Credential Exchange 2.0 and W3C Verifiable Credentials
    • Alpha support for the Indy/Aries Shared Components (indy-vdr, indy-shared-rs and aries-askar), enabling running ACA-Py without using the Indy-SDK, while still supporting the use of Indy as a ledger, and Indy AnonCreds verifiable credential format
    • Feature/Event bus for ACA-Py generated events for controllers
    • Initial support for AIP 2.0 DIDComm envelopes (e.g. ECDH-1PU support)
    • Enable operation without Indy ledger support if not needed
    • Performance fix for deployments with large numbers of DIDs/connections
    • Simplify the creation/handling of plugin protocols
    • DID Exchange implicit invitation handling
    • Add support for Indy 1.16 predicates (restrictions on predicates based on attribute name and value)
    • BDD Tests run via GitHub Actions
  • Breaking changes?
    • DID Exchange Create Request returned the request, and now returns the connection object
    • When endorsement is enabled, the revocation capabilities are not working. For now, don't use the features in combination.
    • Possible – did related methods for handling unqualified did:sov keys
  • What's left?
• Performance issue addressed – redundant Public DID Queries – Andrew Whitehead
  • Issue - public DID checked multiple times per request; old approach was check each DID until public one found; blows up with many DIDs (public or peer) – fixed!
  • Could be improved further with caching, as it is still doing the multiple checks per request, but minor issue
  • Discovered along the way that DIDs from wallet cannot be deleted (e.g. when deleting a connection) – a leftover indy-sdk issue (never implemented). Likely to be addressed in Askar.
• Discussion: What's next in ACA-Py/Getting to 1.0.0
  • Support for did:orb
    • Where do we do this?
    • How are we using external universal resolvers?
  • Support for multiple Indy ledgers
  • Support for revised did:sov
  • Persistent Queues – getting more done on that.
    • Loading and unloading the queues
    • Transports through the event bus, making the mechanism pluggable - inbound and outbound
      • Will require changes in the forward message handling for notifications to mobile devices – generalize this and enable notification handlers to see the message off the bus
      • These are changes to externalize the handling are a step to persistent queues, but not complete answer.
  • AIP 2.0 Features
    • --version 2.0 flag to enable "breaking changes" features/completed community updates
    • RFC 0557 Discover Features V2 – Added AIP 2.0 features / potentially dynamic based on loaded modules
    • RFC 0519 Goal Codes in specific protocols (RFC 0453/0454 - Credential Exchange V2), OOB, DID Exchange
      • Generalized support?
    • RFC 0627 Static Peer DID Support
    • RFC 0183 Revocation Notification – flag on API to notify user (+ connection_id?)
    • RFC 0587 Encryption Envelope V2
    • Review and update as needed all AIP 1.0 RFCs – to be added: a diff link for each "updated" RF
• Questions – AMA:
