What is AT Protocol?

AT Protocol (Authenticated Transfer Protocol) is like a recipe that lets people build their own social media apps instead of relying on one big company [2][4]. Imagine instead of everyone having to use one specific playground, AT Protocol is the rulebook that lets anyone build their own playground where everyone can still play together [3].

Why was it created?

Companies like Twitter and Facebook control all your data and decisions about what you see [5]. AT Protocol lets you own your own identity and data, kind of like owning your own house instead than renting from a landlord [1][4].

How does it work?

AT Protocol is built on simple JSON (just organized information), and it's decentralized, meaning no single company controls it [1][4]. You can move your account and data between different apps that use AT Protocol, similar to how you can take your phone number to different phone companies [3].

Who uses it?

Bluesky Social PBC created and uses AT Protocol to power their social media platform [3][5]. Since it's open, other developers can build their own apps using the same protocol [4].
