OrbitDB is a decentralized data storage system that enables the creation of serverless databases residing across a network of peers. It functions as a peer-to-peer database that integrates with a content-addressed storage layer to distribute and replicate data without a central server.
The system utilizes conflict-free replicated data types to ensure eventual consistency and state convergence across distributed nodes. It maintains an immutable record of updates using a directed acyclic graph to preserve causal ordering and cryptographic integrity. Access is managed through a decentralized identity system that uses public-key cryptography to verify write permissions and authenticate users.
The project provides capabilities for distributed data modeling, including document stores and append-only logs. It supports browser-based networking through relay servers and bridging mechanisms that allow web environments to connect to peer networks. Security is handled via pluggable encryption modules and customizable access validation logic.
The implementation allows for extensibility through custom identity providers, tailored storage backends, and user-defined data models.
