Research on logistics supply chain of iron and steel enterprises based on block chain technology

At present, the service trading system of steel logistics industry is highly centralized, with poor collaborative ability. Information flow, capital flow and logistics need to be certified by logistics center nodes. It cannot achieve information transparency, traceability and tampering, and the information security of customers cannot be effectively guaranteed. This has affected the information security, automation and intelligence of logistics enterprise service transactions. Firstly, this paper introduces the data layer, network layer and consensus layer in the block chain, and then establishes the steel logistics architecture under the block chain technology. Then, it analyzes the management of logistics information resources in the supply chain from the object, attribute and function dimensions. Finally, the improved PFBT algorithm is used to test their de-centralization security and algorithm performance in the system of iron and steel enterprise logistics transactions. The experimental comparison shows that the improved PBFT algorithm has been greatly improved in the aspects of algorithm security, algorithm delay, algorithm throughput and algorithm fault tolerance.
