@evan@cosocial.ca @julian @reiver@mastodon.social 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.
