  • https://github.com/frostyfrog/didcomm-v2-test-util
  • https://github.com/Indicio-tech/aries-cloudagent-python/tree/feat/didcommv2-proof-of-concept
  • Diff: https://github.com/hyperledger/aries-cloudagent-python/compare/main...Indicio-tech:aries-cloudagent-python:feat/didcommv2-proof-of-concept
• ED25519 2020 Verification of JSON-LD Signatures
  • Can issue the credentials
  • When trying to verify – looking for the old style (2018) format – needs to be update
    • Verification is failing because decoding the public key incorrectly – wrong key, looking for base58 key, should be looking for multi-base.
    • Daniel Bluhm does real time debugging and identifies the problem.  Cool!
      
      • Likely here: https://github.com/hyperledger/aries-cloudagent-python/blob/3892e8cfa8fbe7cccc5d20f2e80762ef67bc5a66/aries_cloudagent/vc/ld_proofs/crypto/wallet_key_pair.py#L62-L73
  • Decoding is likely in ACA-Py
• VCDM 2.0 – need to add support for that.
  • Be able to receive/process 2.0 and 1.1
  • Flag at issue time to send 1.1 or 2.0?
  • Discussion for tomorrow at Aries Working Group call to discuss the new vc-di attachment format.
  • How to manage the transition from the current JSON-LD vs using the VC-DI attachment format?
    • How to retain backwards compatibility?
    • How to use the new VC-DI attachments.
    • Importance – using ACA-Py with VC-API – see this issue: https://github.com/w3c-ccg/vc-api/pull/382
• Open Discussion
