Iroh
Iroh is a peer-to-peer networking stack and distributed system designed for secure direct connections, content-addressed storage, and synchronized data sharing. It provides a foundation for decentralized applications by combining a QUIC-based networking layer with primitives for distributed state and data transfer.
The project distinguishes itself through a comprehensive suite of decentralized capabilities, including a distributed data store using conflict-free replicated data types for collaborative synchronization and a content-addressed storage system for verifiable, resumable transfers of large data blobs. It also incorporates a distributed remote procedure call framework and a gossip-based publish-subscribe network for broadcasting messages across peers.
Connectivity is managed through public-key identity addressing and automatic NAT traversal using hole-punching, with relay-fallback routing for restricted networks. The system supports peer discovery via DNS and gossip protocols, ensuring secure, encrypted traffic via public key encryption and multiplexed data streams.
The project is implemented in Rust.
Features
- Peer-to-Peer Networking - Creates secure direct peer-to-peer connections using public-key identity and automatic NAT traversal.
- Content-Addressable Storage - Ships a content-addressed storage system that uses cryptographic hashes to ensure data integrity and enable deduplication.
- Distributed Key-Value Stores - Maintains an eventually-consistent distributed store of key-value pairs across multiple nodes.
- CRDT Databases - Implements an eventually consistent distributed store using conflict-free replicated data types for synchronized state.
- Content-Addressable Transfers - Moves data using cryptographic hashing to ensure content integrity and deduplication across the network.
- Data Synchronization and Consistency - Synchronizes data blobs across multiple endpoints using an eventually-consistent distributed store.
