    • Can that be used with AnonCreds?
      • https://github.com/w3c/vc-test-suite/blob/gh-pages/test/vc-data-model-1.0/50-jwt.js
    • Can we extend this to generate a JWT: https://github.com/andrewwhitehead/anoncreds-w3c-mapping
      • How to do a JWS with AnonCreds.
  • AnonCreds RS:
    • Consuming a credential/presentation in another format should be easy
      • Sniff the format and convert to "internal" format.
        • Receipt of Credential
        • Receipt of Presentation
    • Production of Credential/Presentation in different formats?
      • Add a parameter to indicate the type?
      • Add a call to convert the type?
      • Produce multiple formats?
    • Revocation – how to manage?
      • Not StatusList2021, how to use the "W3C Format StatusList"
  • Other questions from Discord:
    • The process of issuance in this context, more specifically, what does a AnonCreds credential request would look like in w3c format. Is the AnonCreds in W3C VC formats feature only limited to a representation of the already signed and issued credential?
    • To sign a json-ld VC you apply a signature to the Credential, transforming it into a VC without a need to communicate with the holder. With AnonCreds there is an exchange between the issuer and holder to introduce the secret link before the credential is signed.
