- 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 2.0flag 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
- Support for did:orb
- Questions – AMA:
