## What it is
Lighthouse is an open-source Ethereum consensus (beacon chain) client written in Rust, maintained by Sigma Prime. It implements the Ethereum proof-of-stake consensus specification and can run as a beacon node and validator client on mainnet.

## Use cases
- run an Ethereum beacon node
- stake ETH and become a mainnet validator
- run a local Ethereum testnet
- query the Ethereum consensus REST API
- participate in Ethereum proof-of-stake consensus

## When to choose
- you need a security-audited, fuzz-tested Ethereum consensus client
- you want high performance and memory safety from a Rust implementation
- you plan to run a mainnet validator or beacon node on Linux/macOS

## When to avoid
- you need an Ethereum execution client (use Geth, Nethermind, Besu, etc.)
- you only need to read chain data without running a full node
- you need first-class Windows support

## Facets
- artifact type: application
- maturity: stable
- function: security, networking, cli, http-server, testing
- domain: blockchain, microservices, security
- platform: windows, rust, cli
- tags: ethereum, consensus-client, proof-of-stake, beacon-node, validator-client, staking, blockchain-node, cryptocurrency, linux, macos, docker
