An Execution Node is a type of node in a blockchain network responsible for processing transactions and executing smart contracts. It plays a crucial role in confirming the validity of transactions before they are added to the blockchain. When a transaction is initiated, it is sent to the Execution Node, which checks whether the transaction adheres to the network’s rules and protocols. After verification, the node processes the transaction, executing any associated smart contract code, and producing the necessary computational results.Execution Nodes often work in tandem with other nodes, like consensus nodes or validator nodes, which maintain the overall integrity and security of the network. Together, they ensure that all transactions are accurate, efficient, and securely recorded on the blockchain.These nodes can vary in terms of their functionality and requirements, depending on the specific blockchain platform. Some execution nodes may also participate in the consensus mechanism, while others focus solely on executing transactions and contracts.
