Bluesky

Backed by Twitter founder Jack Dorsey, Bluesky aims to redefine the social internet by reducing data silos across online apps.

The Bluesky app runs on the Authenticated Transport Protocol (AT), a decentralized social media framework designed to be open source and interoperable.

Through AT, users can interact with multiple applications within one ecosystem, supporting cross-service conversations and seamless data portability without being locked into a single platform.
