Remote Procedure Call (RPC)

In Ethereum, Remote Procedure Call (RPC) is used to interact with the blockchain. It allows clients to communicate with Ethereum nodes to execute various tasks, such as querying account balances, submitting transactions, or retrieving blockchain data. This is done over HTTP or WebSocket protocols. Developers use JSON-RPC, a standard format, to send requests to the node, which then processes these requests and returns the appropriate responses. RPC simplifies interaction with the Ethereum network, enabling seamless integration and management of blockchain operations within applications.
