did-methods

The word "blockchain" is mentioned only once in the spec, and only in one of the 12 use cases. The garbage part is that 9 of 10 (give or take) methods registered on https://www.w3.org/TR/did-spec-registries/#did-methods are from crypto-hyper-cosmos-nonsense. The reason is that serious organizations like MasterCard or BankID will only begin considering registering a method once the spec is a W3C Recommendation. At this stage, only insignificantly small or heavily invested parties registered a method on a draft standard (which is what a "proposed recommendation" roughly means). Edit: nope, I was wrong, Mastercard has one https://github.com/Mastercard/did-methods/blob/master/id.md

This is discussed in the intro of the spec: https://www.w3.org/TR/did-core/#introduction. My understanding is that the DID method can use a "centralized" identity provider like the Mastercard Identity Service (https://github.com/Mastercard/did-methods/blob/master/id.md), which is presumably backed by some boring database, a decentralized-but-not-blockchain one like IPID which uses IPFS to store and lookup identities (https://did-ipid.github.io/ipid-did-method), or blockchain-specific ones like ENS. > [Verifiable data registries] include distributed ledgers, decentralized file systems, databases of any kind, peer-to-peer networks, and other forms of trusted data storage.
