AT Protocol
An open social networking protocol built around portable accounts and domain-based handles — the technology behind Bluesky.
The AT Protocol (Authenticated Transfer Protocol) is an open standard for social networking built around portable identity: your account, follows and posts aren't permanently tied to one server. It's the protocol behind Bluesky.
