Lighthouse: Ethereum 2.0
An open-source Ethereum 2.0 client, written in Rust and maintained by Sigma Prime.
- Fully open-source, licensed under Apache 2.0.
- Security-focused. Fuzzing has begun and security reviews are underway.
- Built in Rust, a modern language providing unique safety guarantees and
excellent performance (comparable to C++).
- Funded by various organisations, including Sigma Prime, the
Ethereum Foundation, ConsenSys and private individuals.
- Actively involved in the specification and security analysis of the emerging
Ethereum 2.0 specification.
Like all Ethereum 2.0 clients, Lighthouse is a work-in-progress.
Current development overview:
v0.12.3 implemented, optimized and passing test vectors.
- Rust-native libp2p with Gossipsub and Discv5.
- RESTful JSON API via HTTP server.
- Events via WebSocket.
- Metrics via Prometheus.
