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":"df3cb3232433698e5bd6e931a4f9ee50fe391a7e5253cf99282c57f8c696a3da"}
