@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.
@darius Anyways, in the end, excluding the blockchain junk (I'm not gonna pay a cryptocurrency speculator in order to prove my own identity!), if the DID format does take off it's almost certainly going to be because a significant number of people get identities through a small number of big identity providers. :/
