Adoption of did:indy DIDs - Stephen
- CredX for the shared components
- Also need updates for Indy SDK

AnonCreds Proof Request Challenge:

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?
