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 Fabric-PSChain 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.

随着国际贸易的发展，港口运输的核心地位逐步显现。然而，目前港口供应链系统大多采用集中数据管理模式。供应链中的每个运营商都有自己的平台和数据集，容易形成信息孤岛，产生信任问题，导致供应链整体运作效率低下。为提高供应链效率，设计并实现了基于Fabric区块链（Fabric-PSChain）的港口供应链系统。在该系统中，利用区块链去中心化、不可篡改、分布式共识的优势，结合基于角色的访问控制策略（RBACP），开发了四个智能合约，实现了访问控制策略制定、企业列表查询等功能。 , 货物订单上传，订单查询。同时在Fabric-PSchain系统中加入了监管节点，以增强数据的可信度和安全性，满足监管合规要求。实验结果表明，Fabric-PSChain系统具有重要的保密性和数据共享性，可以加快港口供应链业务的运行，对航运物流行业具有重要的应用价值。
