Through the WebSocket protocol, blockchain nodes can establish connections for real-time information exchange. The WebSocket URL points to the address of the WebSocket server, and nodes connect to these servers to receive and send data. In a blockchain system, nodes can request information such as blocks and transactions, and receive real-time data sent by other nodes. This communication method improves the reliability and security of the blockchain network because data transmission does not depend on the existence of a single point. Additionally, the WebSocket protocol is suitable for real-time applications such as chat tools and games, thus enabling faster and more efficient communication between users."}]}],"pr":"0bd8a3bdd35db3ac494c68bb38de34a1cc3ad41d8b3f0a67c9b7a4bd6c184d95"}
