Indigo
Indigo is a Go-based framework and toolkit designed for building, hosting, and scaling services within the AT Protocol ecosystem. It provides the foundational infrastructure for decentralized social networking, enabling developers to implement relay services, manage cryptographically signed user repositories, and handle identity resolution across federated environments.
The project distinguishes itself through a robust architecture that decouples content hosting from discovery, allowing for independent moderation and algorithmic feed generation. It utilizes content-addressed storage and Merkle-tree-based repository structures to ensure data integrity, while its lexicon-driven schema generation automatically creates type-safe structures for cross-service communication. By mapping human-readable handles to decentralized identifiers, the system maintains verifiable user ownership and account portability across independent hosting providers.
Beyond its core identity, the project covers a comprehensive surface for managing distributed state, including real-time event streaming, synchronization, and automated moderation. It provides extensive tooling for network activity simulation, operational telemetry, and the indexing of global data streams. The framework is designed for production environments, offering containerized deployment options and diagnostic endpoints to monitor synchronization health and system performance.
