what's nimbus?
Nimbus is a lightweight and high-performing Ethereum client designed to minimize hardware requirements for running nodes, making it accessible for solo stakers and efficient for institutional operators. Developed by Status, it supports both execution and consensus layers, emphasizing resource efficiency and mobile-friendly features. The client is written in the Nim programming language for speed and low resource usage. It is trusted by various node operators, including liquid staking protocols, and contributes to Ethereum's decentralization by enabling broader participation in validation. Nimbus focuses on scalability and security, with ongoing developments for light client functionalities.
Nimbus released v26.1.0, a low-urgency update improving validator stability and fixing crashes.
