Hi all, DCC (https://digitalcredentials.mit.edu/ ) and Credential Engine (https://credentialengine.org/ ) have been doing a research project since early summer about registries and their governance. The DCC will publish a registry for our members and include it in our wallet (lcw.app) and web verifier (https://verifierplus.org/) that will stand as an open-source reference implementation. Credential Engine is also exploring publishing a registry too. You can learn some about our choices here: https://blog.dcconsortium.org/selecting-the-openid-federation-specification-for-the-dcc-and-credential-engine-issuer-registry-f9079f620472 We will be having an advisory group meeting on Feb 5 where we plan to provide a demo of the direction we’ve chosen. You can join the advisory group here: https://docs.google.com/forms/d/e/1FAIpQLSczZ44izmA_H4Bg7NkOoUUn6s0mXVVo-yRALNNTYEKcyDcZNg/viewform What we’ll be recommending is documented governance policies for each registry that answers questions like the ones that Julien raised to inform verifiers. We’re also keeping an eye on and communicating with https://ayra.forum/. We’ll likely bring this demo to CCG and VC-EDU at some point too.

I guess the main issue I’m trying to tackle is how to rule out a malicious actor actively impersonating an official issuer. Think for instance of someone who is able to set up a thorough infrastructure with DIDs or Controller Documents and whatever mechanism in place to sanction the validity of the public keys used (CEL, did:webvh, KERI, etc) but using a clone domain similar as to what would be done in a phishing attack (ie: instead of https://www.dmv.ca.gov/portal/, you would have someone use https://www.dmv-california.org or similar to host any web based information and “spoof” an identity). I’m guessing I am not the only one working on such a matter so I’d like to hear about things that I might have missed thus far. I have looked at the solutions listed above, but to me they don’t suffice to address the use case I’m exposing. And I think, generally speaking, DIDs can have a similar weakness: you probably read about that French woman who got scammed by her fake Brad Pitt boyfriend, the attacker could have presented a fake Brad Pitt DID that wouldn’t have likely triggered any alarm. I know trust registries can be used but several issues can arise: * How do you get registered (aka accepted)? * As a small new actor in a field, or an individual, isn’t the process a barrier of entry? * How do you trust the goodwill and intentions of who signs off an entry into the registry? * Who manages the registry? * And if all of that is centralized, isn’t this just a glorified CA? * If it’s decentralized, what’s the incentive to run a node/governance (cryptocurrency?)? Witnesses are also an option, but again, how do you trust the network of witnesses. Scammers could very well set up their own network of witnesses and point to each other. Is there some work going on at this level, protecting the end human user against their own naivety?
