@darius Hmm. In terms of a generic data format, sure, that spec seems fine but kind of boring. It doesn't say anything other than "here's a URI format", "here's a document format", and "you have to use a resolver (not specified here) to get from one to the other".
The actual meat of the spec is over in https://w3c.github.io/did-spec-registries/#did-methods and the heavy association with proof-of-work cryptojunk really turns me off :(
@darius The Tor DID spec actually looks pretty interesting tho: https://blockchaincommons.github.io/did-method-onion/ since it's self-validating (the DID uri is literally an Onion site url aka public key) and builds upon an existing decentralized registration system that does not require use of a blockchain.
And there's a web-based spec as well, which appears to use DNS for validation.
