Other Business

• Future of this meeting (and Indy collaboration generally)

  • We recognize as a community that each of us needs to adapt to current global events: improving the upstream open source libraries is likely to be slower.

    • Note from Aries calls: no apology is needed if people take longer to respond to things.

    • Evernym focused on a COVID19 response project through end of May

      • Richard's role changed, so we need a change in host for this meeting

    • More async collaboration

Future Calls

Next call:

Future:

• Requirements questions:

  • IS-1099: anoncreds.prover_get_credentials_for_proof_req should return per-credential timestamp

    • Should we allow duplicate credentials from the same issuer?
