Why the AT Protocol?
AT Proto is a network for portable social data pioneered by Bluesky. It separates identity, data storage, and product experience so you can choose where data lives while still reaching the same network.
- DIDs for stable, user‑owned identity.
- Repos of signed records for posts, lists, and more.
- Personal Data Servers (PDS) you can self‑host or switch between.
- Federation for reach; composability for innovation.
