Abstract: Most of the current cold chain logistics systems use centralized solutions. Data management is done by logistics companies alone, and a series of trust problems have emerged. Aiming at these problems, a blockchain technology solution for the cold chain logistics industry is proposed. By using the characteristics of decentralization and de-trusting unique to the blockchain, a chain-up system is designed for the order data and environmental data. The order data security chain, cold chain environment data real-time uplink and IoT device identity authentication and authority control mechanism improve the credibility and data security of the cold chain logistics industry. Through the system prototype, it shows that the program can meet the business needs and has an important impact on the cold chain logistics industry.
