Rust implementation of the Serenity Beacon Chain, maintained by Sigma Prime.
Lighthouse is an open-source Ethereum Serenity client that is currently under development. Designed as a Serenity-only client, Lighthouse will not re-implement the existing proof-of-work protocol. Maintaining a forward-focus on Ethereum Serenity ensures that Lighthouse avoids reproducing the high-quality work already undertaken by existing projects. As such, Lighthouse will connect to existing clients, such as Geth or Parity-Ethereum, via RPC to enable present-Ethereum functionality.
