This study focuses on the existing problems of railway spatiotemporal data sharing and proposes the use of blockchain technology to provide trusted sharing methods for railway spatiotemporal data. By analyzing the relevant problems faced by blockchain in the application of trusted sharing of railway spatiotemporal data, the node consensus mechanism, data sharing flow model, data encryption, and data traceability system for railway spatiotemporal data exchange and sharing are studied The key technologies of data governance strategies based on consensus mechanisms and smart contracts provide new ideas and technical support for railway spatiotemporal data flow and sharing, in order to solve the problems of opaque information sharing, information asymmetry, lack of trust, and difficulty in verifying and tracing data in the current railway industry.
