RPC stands for Remote Procedure Call, a protocol used for communication between a client and a server. In the context of cryptocurrency, RPC allows different software applications to interact with blockchain networks.When users want to perform actions like checking their balance, sending transactions, or querying blockchain data, they can send requests through RPC. These requests are formatted as specific commands that the server can understand.The responding server processes the request and sends back the relevant information or confirmation. This process is often used by wallets, exchanges, and decentralized applications to interact with blockchain nodes.RPC can operate over HTTP, WebSocket, or other communication methods, providing flexibility in how applications access blockchain functionality. Because it enables real-time interaction with the blockchain, RPC is crucial for supporting various features and services in the ecosystem.In summary, RPC acts as a bridge for applications to seamlessly communicate with blockchain networks, facilitating essential operations and user interactions.
