The AT Protocol (ATProto), which powers the BlueSky social media platform, introduces decentralized identity and data management, allowing developers to create user-centric applications. This session dives into the mechanics of ATProto's identity system and how to integrate it into .NET applications. We'll walk through implementing identity verification, managing data across decentralized networks, and creating C# code for seamless ATProto integration. By the end of the talk, you'll have the practical knowledge to develop robust decentralized identity solutions.
