What are your thoughts on https://w3c.github.io/vc-data-model/
and implementing it over Zot?
At a high level it seems possible by declaring a did method (e.g. "did:zot:<chanhash>"), and then using something simpler for the signatures such as Zot already uses (spec gives LD-SIG and JWS as example but seems to allow you to do whatever you want)
What do you think?
