Agenda

Open Issue

  • PRs for review and merging

  • Issues to Discuss

  • Any update on what "prover_did" is used for during AnonCreds processing?

    • Does the value require any special characteristics when it is used in the AnonCreds code?

    • Any insight on why it was added in the first place?

    • If we were to deprecate it as an input, would we need to use something else to replace it in the AnonCreds code?

  • Help with dependabot pull request: 113

  • Checkin: anoncreds-rs implementation progress, requests

  • Open Discussion

Future Calls

To Dos:

  • Issue to be added and further investigation into what happens to the nonce(s) by Belsy.

  • Backwards Compatibility

    • PRs in (#82, #105) that seem to change public data structures – ones that are handled outside of AnonCreds and/or by two or more participants (issuer, holder, verifier)

    • We want to retain compatibility with existing data – credentials that have been issued and the published AnonCreds objects on which they rely.

    • That extends to business logic – e.g. the handling of the objects not just by AnonCreds, AnonCreds Methods and Aries Frameworks, but also by business applications built on Aries.

    • Suggestion:

      • Include in the specification a statement about backward compatibility

        • Perhaps this is what Ankur had planned to do?

      • Formalize what data structures will be expected by AnonCreds

        • This is being done throughout the specification and verified against the current implementation.

      • As needed support sending and receiving data in "old" and "new" formats, but (for now) always sending "old" formats.

        • TBD if there are any such cases.
