Each node 101 may receive input information and maintain shared data (i.e., blockchains) within the blockchain network based on the received input information while operating normally. In order To ensure information intercommunication in the blockchain network, each node may have information connection, and any two nodes may implement Peer-To-Peer (P2P) communication, and specifically may perform P2P communication through a wired communication link or a wireless communication link. For example, when any node in the blockchain network receives input information, other nodes acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes in the blockchain network are consistent.
The testing platform 102 and the certificate authority 103 may access the blockchain network and may communicate with nodes in the blockchain network, for example, submit transaction data to be linked to the nodes, obtain data from the nodes, and so on. The testing platform 102 and the certificate management authority 103 may communicate with each other, and the terminal device 104 corresponding to the user and the terminal device 105 corresponding to the vehicle management may access the testing platform 102, where the terminal devices 104 and 105 may be a smart phone, a tablet computer, a notebook computer, a desktop computer, a vehicle-mounted intelligent terminal, and the like, and the embodiment of the present invention is not limited thereto.
