Teku
An open-source Ethereum consensus client implementing a full beacon node and validator client in Java.
Overview
Teku is an open-source Ethereum consensus client developed by ConsenSys, designed to run a full beacon node and validator client for Ethereum's proof-of-stake consensus layer. Written in Java, Teku supports the Ethereum Beacon Chain specification and is built to meet the needs of institutional and enterprise users who require a robust, scalable, and secure client implementation. It plays a critical role in Ethereum's transition to a proof-of-stake network by enabling validators to participate in block proposal and attestation processes.
Teku offers comprehensive features including REST API support for monitoring and management, compatibility with Ethereum's consensus specifications, and support for both mainnet and testnets. It is designed for easy integration into existing infrastructure with Docker images and binary releases available for straightforward deployment. Teku emphasizes security and performance, leveraging Java's mature ecosystem and Google's Java coding conventions to maintain code quality and reliability.
What sets Teku apart is its focus on enterprise-grade stability and compliance with Ethereum's evolving consensus protocols. Unlike some other clients, Teku is backed by ConsenSys, a leading Ethereum software company, ensuring ongoing development, support, and alignment with Ethereum's roadmap. Teku's open-source nature and active community engagement via Discord and GitHub facilitate transparency and collaboration.
Developers and infrastructure teams can get started by installing Java 21 or higher, cloning the Teku repository, and building the client using Gradle. Detailed documentation covers installation, configuration, API usage, and validator operation. Teku also provides release notifications and community support channels to keep users informed and supported throughout their deployment lifecycle.
The Problem
Running a reliable and secure Ethereum consensus client that fully supports the Beacon Chain and validator operations is complex, especially for enterprise users needing stability and compliance with Ethereum's evolving proof-of-stake protocol. Many existing clients may lack enterprise-focused features or comprehensive support for the latest consensus specifications.
