Teku
A Java-based Ethereum consensus client by ConsenSys — enterprise-friendly, with strong observability and integration into the Hyperledger / Besu stack.
Teku, originally Artemis, is the Java consensus client by ConsenSys (and part of the Hyperledger ecosystem). Its design optimizes for enterprise validator operators: strong metrics, clean logs, JVM tooling, and integration with the JVM-based Besu execution client.
Teku is one of the four production consensus clients and a key contributor to client diversity, particularly in institutional staking deployments where Java operability matters.
