Issue 6 and 8 (ZKP and JWT) implementers

[Iso5786]

Hi all,
on the VC data model 1.0 page it states under issue 6, that "Zero Knowledge Proofs are a feature at risk. The Working Group is looking for multiple implementers to support the feature during the W3C Candidate Recommendation phase."
I cannot find any related issue here, hence I create a new one to introduce a project that implements this feature.

This project is called IRMA, maybe some of you already read about it.
From the official doc:
"IRMA is a set of software projects implementing the Idemix attribute-based credential scheme, allowing users to safely and securely authenticate themselves as privacy-preserving as the situation permits" (via https://irma.app/docs/what-is-irma/)
How IRMA uses ZKP is described here: https://irma.app/docs/zkp/.

Currently, I am writing my master thesis about whether it is possible to embed the IRMA infrastructure within the VC specification / how to make IRMA comply to the VC specification.

Kind regards,
Daniel Ostkamp

This is excellent news. I am working on an implementation for Evernym, and @ken-ebert is doing one for Sovrin, both of which will also support ZKPs.
We'd love to touch base with you as you work through incorporating VCs into IRMA. And we invite you to add a test suite implementation

@brentzundel Good to gear! Am now in the phase of describing IRMA and VC in detail and starting to identify differences in concepts of both.
How would you like to touch base with me? I suggest to have a skype call once I have set some first steps incorporating VCs into IRMA (like in a month or so).
I already had the test suite on my todo list but it's not top priority at the moment.

Additionally, IRMA can be configured to use JWT (see https://irma.app/docs/session-requests/#jwts-signed-session-requests) because in the VC spec issue 8 states that the JWT support is a feature at risk.

@brentzundel Could you provide more information about the projects you mentioned? Also, what are other projects trying to implement VC? This would be useful for my thesis later to mention it in the related work.

@Iso5786 I sent an email to the address in your profile to continue the conversation.

I recommend we close this issue, as it doesn't call for any changes to the spec.
