Re: Verifiable Data Registries

Are there any examples in production or PoC where a P2P network has been used by a developer to publisha DID method that verifiers are trusting?

Some configurations might require correlatable identifiers for subjects. Example verifiable data registries include trusted databases, decentralized databases, government ID databases, and distributed ledgers. Often there is more than one type of verifiable data registry utilized in an ecosystem.

Usually, i have been equating it to a DLT, but I know that I have heard conversations indicating that it specifically was not restricted to this technology.

I am currently working on a definition of the term for section 2 (Terminology) of the DID spec, since we made decision to switch from DID Registry (which has always been a very confusing term in the context of DIDs) to Verifiable Data Registry so that we are in fact using the same term as was used in the Verifiable Credentials Data Model 1.0 spec.
