An execution client is a software component that processes transactions and produces blocks on a blockchain. It is responsible for validating and executing code, managing the state of the blockchain, and ensuring that transactions are accurately carried out according to the network’s consensus rules.In networks that use proof-of-stake, the execution client operates alongside a consensus client. While the execution client focuses on transaction processing and state management, the consensus client handles block validation and network consensus. Together, they work to maintain the integrity and security of the blockchain.Users, developers, and miners run execution clients to interact with the blockchain. This software can include functions for sending transactions, querying the blockchain’s current state, and reading data from the network. Common examples of execution clients include Geth for Ethereum and other clients designed for various blockchain platforms. They play a crucial role in enabling user interaction and application development within the ecosystem.
