@julian @reiver @silverpill There are about 390M registered domain names. The system has, in fact, been used for decades. The Web and email depend on DNS.

Cryptographic keys as the root of identity are extremely hard for people to use -- about 10% of all Bitcoin wallets with money in them are lost for good. And there's actual money in those.

DNS >> cryptographic keys

@evan @julian @reiver Cryptographic identity is also not a new technology, PGP was developed more than 30 years ago, and a lot has happened since then. Hardware keys, HSMs in smartphones, etc. And DIDs.

DID is an abstraction that allows key rotation and delegation of key management to a trusted 3rd party. Bluesky uses DIDs for identities but most of its users never touch a secret key.

Anyway, in Fediverse we don't need to choose between domain names and DIDs. We have both, because FEP-ef61 is a backward compatible protocol upgrade.
