Traceability of Product Supply Chain Based on Hyperledger Fabric

Abstract

Abstract: At present, more and more consumers and manufacturers are aware of the importance of product traceability, so it is very important to strengthen the traceability in the supply chain. The existing centralized database system has isolated data storage, and many parties involved in data query lack mutual trust. Based on the distributed ledger of the blockchain, this paper attempts to solve this problem by transforming the traceability information of physical goods into the digital of the blockchain, so as to realize the collaborative traceability of entities in the supply chain. At present, the relationship between components and products in manufacturing process cannot be captured, which limits the ability to track the source of products. This paper proposes a supply chain traceability model based on blockchain, which uses smart contracts to
