feat: add anoncreds attachments rfc #771

Closed TimoGlastra closed 1 year ago

TimoGlastra commented 1 year ago

Adds an RFC for the new AnonCreds credential format. The RFC is mostly based on RFC 0592, with some changes:

Some names have been changed to align more with the spec.
Remove references to indy-sdk code
Remove encoding algorithm and instead point to the specification
Update the proof request to not allow a nonce when using for a proposal, while requiring it for a request (see https://github.com/hyperledger/aries-rfcs/issues/766).

@dhh1128 I've included you as an author as the RFC is mostly based on RFC 0592 which you wrote. Let me know if you'd like your name removed.

Fixes #761

Good addition!. One question. Since you are updating RFC 0453: Issue Credential Protocol 2.0 and RFC 0454: Present Proof Protocol 2.0, should its minor version be updated as well?

I was of the understanding the attachments registry could be updated separately form the issue credential / present proof protocols. Since you're not required to support any of these attachments, and you're even allowed to use other attachment formats I'd assume, updating the version would not change anything. But good to raise this during the Aries WG call, I'm not sure on this one
