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.

摘要： 目前的冷链物流系统大都采用中心化的解决方案，数据管理由物流企业独自完成，出现了一系列信任问题。针对这些问题，提出了一种面向冷链物流行业的区块链技术解决方案，利用区块链特有的去中心化、去信任化的特点，针对订单数据和环境数据分别设计上链系统，实现了订单数据安全上链、冷链环境数据实时上链以及物联网设备的身份认证与权限控制机制，提高了冷链物流行业的可信性和数据的安全性。通过系统原型实现与测试，表明该方案可以满足业务需求，对冷链物流行业有重要影响。
