Re: Plugfest 3 Proposal

Hi David,

Can you clarify/expand the question? In the general VC ecosystem, there's
no assumption that there's any trust relationship between the wallet and
the verifier.
(There is the assumption that the wallet will accurately convey to the user
the verifier's identity, that is, WHO is asking for the credentials. But
that's different from a trust relationship between wallet and verifier.)
