In order to achieve secure and efficient data sharing and exchange between railway and other industries, based on the business characteristics of the railway industry,we established a blockchain-based railway data sharing and exchange system. In this paper, we proposed a data storage and aggregation scheme that combines on-chain and off-chain data, and an improved consensus algorithm for data sharing based on the characteristics of railway blockchain node structures. The railway industry data exchange and sharing blockchain model proposed in this paper ensures data security while meeting the needs of secure and efficient data exchange between railways and other industries.
