The AT Protocol (Authenticated Transfer Protocol, commonly shortened to atproto)[ 1] [ 2] is a protocol and open standard designed for building federated social networking services.[ 3] It is currently under development by Bluesky Social PBC, a public benefit corporation that was originally created as an independent research group for Twitter to investigate the possibility of decentralization,[ 4] and powers its Bluesky social network.[ 5] [ 6]

The protocol has been designed to address perceived issues with other decentralized protocols, addressing account portability of user data and social graphs, as well as platform interoperability and customizable algorithms. Bluesky Social has promised to transfer development of the protocol to a standards body such as the IETF in the future, as declared by CEO Jay Graber.[ 7]

The AT Protocol aims to create a decentralized, interoperable, and scalable online ecosystem where users can retain and manage a single federated online identity across various online platforms and services. The protocol's design prioritizes discoverability and an integrated, customizable, user-centric online experience. Bluesky Social describes the protocol as being "modeled after the open web itself".[ 8]
