Reth

Reth is a modern, open-source Ethereum full node implementation written in Rust, designed to be secure, fast, and modular. It serves as an Execution Layer (EL) client compatible with all Ethereum Consensus Layer implementations supporting the Engine API. Developed and maintained by Paradigm, Reth aims to improve client diversity in the Ethereum ecosystem by providing a performant alternative to existing clients. It is also designed to support other EVM-compatible chains such as Optimism, Polygon, and Binance Smart Chain, with aspirations to expand further.

Reth's architecture emphasizes modularity, allowing developers to use its components as libraries for custom node builds, standalone P2P networks, or offchain services. It leverages the Erigon staged-sync architecture and integrates optimized Ethereum libraries like Alloy and revm for efficient transaction processing and fast syncing. The node supports configurable profiles to balance hardware requirements and sync strategies, catering to both hobbyists and professional node operators.

Production-ready since mid-2024, Reth is trusted by institutional users including Coinbase for staking and MEV applications. Its open-source Apache/MIT licensing encourages community contributions and broad adoption without restrictive licensing concerns. Developers can get started by installing prebuilt binaries or building from source, with comprehensive documentation and active community support available via Telegram and GitHub. Reth also provides extensive crates for integration as a library, enabling flexible and innovative blockchain infrastructure development.
