AMA with the Developers

• PR: Loosen restrictions

• PR: ECDH-1PU – what next?

• PR: Small AIP-2 updates - what next?

• What up with canonicalized schema attributes – seems wrong.

• Endorser Protocol – what do we do next?  Demo? Are we using it in the OrgBook Issuer Service?

  • How to handle auto-endorse?

• Describe Feature/Event Bus

  • Goal - webhooks to other parts of ACA-Py, Plugins to ACA-Py (vs. multiple external listeners)

    • A layer between event creation and subscribers to allow internal subscribers

    • Use case – plugin subscriber to push events to a Kafka queue.

    • Need to update the persistent queue work – make it a plugin?

    • How to convey how/when to use this to other developers

    • Integration test or walk-through of how to use.

Issues: 

• Too many!  Need to have a culling. 94

• Hot ones?

  • Problem Reports

    • Key Case: Receiving PR within the Credential Exchange to do clean-up, etc.

      • Change the message family

    • Also important - sending Credential Exchange specific PR.

    • PR schema with the RFC.

  • JSON-LD Performance - contexts are not cached.

    • Once BBS PR is merged, does some replacements with re-route.

  • Aries Go Interop – base64url, recipientKeys/routingKeys, DIDDoc

    • Addressed in "small AIP 2" PR.  Or at least should be...

Progressing on initiatives; priorities

• Adding a JSON-LD, BBS+, PE Demo

  • What keys, what ledger?

  • What does the PD look like?

• AF-Go Interop – how?

• Persistent Queues – Need On/Off queue implementation

Requests?

Double Signature with eIDAS?

• Background: https://www.slideshare.net/FIDOAlliance/introduction-to-fido-and-eidas-services

• SICPA - For the eSSIF program, with json-ld credential we are adding double signature, the normal + eIDAS
  
  

  • @Mateo

• Double signature in ACA-Py with pluggable mechanism, and implementation for eIDAS
