Modeling and analysis of port supply chain system based on Fabric blockchain

With the development of international trade, the core position of port transportation progressively emerges. However, most current port supply chain systems adopt a centralized data management mode. Each operator in the supply chain has its platform and data set, which is prone to form information islands and can create trust issues, resulting in the inefficient overall operation of the supply chain. To improve the efficiency of the supply chain, a port supply chain system based on Fabric blockchain (Fabric-PSChain) is designed and implemented. In the proposed system, four smart contracts are developed by taking advantage of the blockchain's decentralized, tamper-free, distributed consensus, combined with the Role-Based Access Control Policy (RBACP), realizing the functions of access control policy formulation, enterprise list query, cargo order uploading, and order query. At the same time, the regulator node is added to the Fabric-PSchain system to enhance the credibility and security of data and meet regulatory compliance requirements. Experimental results show that the FabricPSChain system has vital confidentiality and data sharing that can speed up the operation of the port supply chain business and has significant application value for the shipping logistics industry.
