All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1a, it is a schematic diagram of an architecture of a ticket reimbursement system according to an embodiment of the present invention, where the data processing system includes a blockchain network 10, an invoicing terminal 11, a user terminal 12, a supervision platform 13, and an reimbursement platform 14. Wherein:
the blockchain network 10 specifically refers to a network for performing data sharing between nodes, and the blockchain network may include a plurality of nodes 101. 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.
Billing terminal 11, user terminal 12, administration platform 13 and reimbursement platform 14 may have access to the blockchain network and may communicate with nodes in the blockchain network. The billing terminal device 11, the user terminal 12, the monitoring platform 13, and the reimbursement platform 14 may be a smart phone, a tablet computer, a notebook computer, a desktop computer, a vehicle-mounted smart terminal, and the like.
TABLE 1
| Node name | Node identification |
| Node 1 | 117.114.151.174 |
| Node 2 | 117.116.189.145 |
| … | … |
| Node N | 119.123.789.258 |
Each node in the blockchain network has a corresponding node identifier, and each node in the blockchain network can store node identifiers of other nodes in the blockchain network, so that the generated block can be broadcast to other nodes in the blockchain network according to the node identifiers of other nodes. Each node may maintain a node identifier list as shown in table 1, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an Internet Protocol (IP) address or any other information that can be used to identify the node, and the table is described by taking the IP address as an example.
