RPC stands for Remote Procedure Call, a method that allows a program to execute a procedure or function on a remote server as if it were local. In the context of blockchain systems, RPC enables interaction between clients and nodes, facilitating communication with the blockchain network.Through RPC, various operations can be performed, such as sending transactions, querying the blockchain for data, or retrieving account balances. This is done over the network using specific protocols, often utilizing JSON-RPC or XML-RPC for data interchange.Developers commonly rely on RPC to build decentralized applications (dApps) that require real-time access to blockchain data. By using RPC, these applications can seamlessly execute commands and retrieve information without needing to manage the underlying complexities of the network. This capability enhances user experience and simplifies integration with other services, making it an essential component in the functionality of many blockchain-based systems.
