Gun is an open source protocol for building decentralized applications that sync data across peer-to-peer networks using graph data structures and end-to-end encryption. Developers use it to build offline-first applications with real-time data synchronization, avoiding centralized servers while maintaining data consistency through CRDT (Conflict-free Replicated Data Type) algorithms. It's useful for creating distributed databases, web3 dapps, and applications requiring encrypted data sharing without a single point of failure.
