What does rpc node mean?

In the Web3 world, RPC Node (Remote Procedure Call Node) is crucial. RPC Node is a protocol for requesting remote computer services over the network without knowing the underlying network technology. It is widely used in Web3 to interact with the Ethereum JSON RPC API through libraries (such as web3.js), providing rich JavaScript objects and functions, supporting functions such as viewing blockchain status, sending transactions, and compiling smart contracts.

‌In Web3, RPC Node refers to the remote procedure call (RPC) node. ‌ RPC Node is a protocol for requesting services from remote computers over the network without requiring knowledge of the underlying network technology. It assumes the existence of certain protocols, such as TCP/UDP, to carry information data between communicating programs‌.

The application of RPC Node in Web3 is very important. By using libraries like web3.js, developers can encapsulate Ethereum’s JSON RPC API and provide a series of JavaScript objects and functions for interacting with the blockchain, including viewing network status, viewing local accounts, viewing transactions and blocks, and sending Transaction, compile/deploy smart contracts, call smart contracts, etc.‌.

Running RPC Node requires the support of high-performance computers and professional knowledge. For example, running a Cardano node requires at least 10GB of RAM and 24GB of hard drive space, and requires a high-quality network connection. Maintaining such equipment requires expertise in DevOps and software engineering‌.
