Research on the application of blockchain in supply chain information sharing

There are some problems in traditional supply chain, such as information asymmetry and weak traceability. To solve these problems, this paper proposes a supply chain information sharing system based on block chain technology, combining with the characteristics of block chain technology. Firstly, the framework of information sharing system based on information chain and supply chain participants was constructed. Secondly, the interaction rules of information sharing process were designed to meet the actual demand of supply chain information interaction. At the same time, based on the role-based access control model, the system authority management mechanism was established to standardize the interaction between supply chain enterprises. Then, the information intelligent contract was deployed based on the above rules, and the supply chain information sharing system was established. Finally, the scheme was compared and analyzed through experiments. The results show that the scheme has certain advantages in the overall system function, fault tolerance and throughput, and can realize the efficient and secure sharing of supply chain information.
