Space-time block chain node equipment and object identification and evidence storage method

The invention discloses a space-time block chain node device and an object identification and evidence storage method, relates to the field of block chains, and aims to solve the problem that the space-time block chain node device in the prior art lacks identification and judgment on the reliability and credibility of a data source, and adopts the technical scheme that the space-time block chain node device comprises a main node and star nodes, the star nodes collect article feature information and upload the article information, position and time information to the main node, the main node compares the information collected by the star nodes for verification, the technical scheme performs intelligent identification on an object, encrypts data and generates a digital label, and aims to perform intelligent identification and judgment on a target of a data source, so that the accuracy of the data source is improved. The problems of reliability and credibility recognition and judgment of a data source object upl
