ethlambda is a minimalist, fast, and modular implementation of the Lean Ethereum consensus client, built by LambdaClass with deep expertise in distributed systems and blockchain infrastructure.
Open source · MIT license · Built and maintained by LambdaClass
A cutting-edge consensus client for the next iteration of the Beacon Chain: the Lean Chain.
Developed by LambdaClass, the team behind ethrex 🦖, the production-ready Ethereum execution client.
Less than 10k lines of Lean code with low abstraction: easy to maintain, read, and audit.
Fully open-source, with an active dev team and contributions welcome.
Full technical documentation covering setup, configuration, devnet integration, metrics, and the client's internal architecture.
