AnonCreds Proof Request Challenge: (last week notes)

• Holder has one of N credentials with different schema, issuers
• Is there a single AnonCreds proof request that allows the holder to construct and proof that can be verified for that scenario?
• Assuming you can't - what can we do?
  • Present Proof Negotiation 
  • Modification to the Present Proof "request-presentation" message semantics to allow multiple proof requests
  • Use DIF Presentation Exchange with AnonCreds
  • Other ideas?

Other Business

Future Topics

• decorator for redirection after proofs. - existing?
• Standardized attribute names for AnonCreds - alignment with VC data model. (Paul Bastian)
  • terms and conditions (as link)
  • machine-readable governance?
