Embodiment 1
[0053] Such as figure 1 As shown, the present invention provides a device for authenticating blockchain data using spatiotemporal information, which includes a spatiotemporal blockchain terminal, a spatiotemporal encoding module, a blockchain module, and a server;
[0054] 1. Space-time blockchain terminal
[0055] The spatio-temporal blockchain terminal is a special device used to authenticate the authenticity of the blockchain data source. The spatio-temporal blockchain terminal includes a satellite positioning module, a computing module, and a communication module. The satellite positioning module, computing module, and communication module are electrically connected together. The space-time blockchain terminal is connected to the network of the blockchain module through the communication module, and connected to the network of the space-time encoding module through the communication module.

Embodiment 2
[0078] Such as figure 2 As shown, a method for authenticating blockchain data using spatio-temporal information, the method is based on the spatio-temporal blockchain tag of the spatio-temporal blockchain terminal and the spatio-temporal blockchain tag stored in the blockchain module for cross-validation, the specific steps as follows:
[0079]Step 1: Deploy the space-time encoding module and blockchain module on the server;
[0080] Step 2: Register at the spatio-temporal blockchain terminal;
[0081] The space-time blockchain terminal sends its coordinate position to the space-time encoding module;
[0082] The space-time encoding module generates a string as the unique number (device ID) of the space-time blockchain terminal through the space-time encoding encryption algorithm according to the time and geographic coordinates (longitude, latitude) sent by the space-time blockchain terminal, and the space-time encoding encryption algorithm f 1 , equipment number ID, geogr...
