A Cross-chain Gateway for Efficient Supply Chain Data Management

With the development of economic globalization, a product usually involves different organizations from the origin to retail. These organizations form a supply chain to collaborate to provide products to end-users. The arrival of the digital age offers excellent convenience for the supply chain management. However, it is difficult for existing supply chain management systems to share credit, which leads to end-users’ concerns about the quality of products. The blockchain technology, characterized by tamper-proof, traceability, and distributed sharing, is expected to solve the it. Also, supply chain management also increasingly depends on the use of the Internet of things. However, the throughput limitation of current blockchain systems significantly constrains their applications to IoT data storage and management. In this paper, we propose a cross-chain solution based on IOTA and Fabric for supply chain data management. We design and implement a supply chain data management system based on a cross-chain gateway of blockchain. The system has three layers, including blockchain layer, business layer, and application layer, which provide essential logistics functions in supply chain management. Finally, we conduct experiments to validate the effectiveness of the implemented system.
