AT Protocol,
Sept 21, 2024
As the overview says, "the Authenticated Transfer (AT) Protocol, aka atproto, is a federated protocol for large-scale distributed social applications." It is the alternative protocol created by BlueSky to replace the ActivityPub used by Mastodon and the rest of the fediverse. Did the world need more than one fediverse protocol? That's debatable, but there are others as well, and there's nothing inherently wrong with it. One key attribute they're tackling is identity: "Users should be able to create global IDs which are stable across services. These IDs should rarely change to ensure that links to their content are stable." Since they're all (supposed to be) open protocols, people can build bridges between them and make them interoperate, which is what Bridgy Fed has been doing. Via Paul Frazee. Image: Wikipedia.
