The authenticated transfer protocol is at the base of the Bluesky social network. It uses self certifying data structures to share information across the network. Central to the idea is that authenticity and authority of the data is rooted in persistent user controlled identifier instead to network locations (A typical example of the latter is authentication based on the WEBPKI that is DNS based).

The technology allows user owned data to be portable across the network and provider independent and therefore enhances the agency of individual users.
