Hyper-FTT: A Food Supply-Chain Trading and Traceability System Based on Hyperledger Fabric

Abstract

Building a food traceability system provides an effective way solving the problems arousing in the food safety domain. Blockchain is preferred to construct a commodity traceability system due to its innate immutability and consistency of stored data, maintained through cryptographic means and consensus mechanism. While current blockchain based traceability system just collects and stores verified commodity information in the chain, which is composed of a decentralized ledger architecture. But the information is less accurate or intact which cannot trace the real food source along the food supply-chain. We propose to establish a Hyperledger-based Food Trading and Traceability system called Hyper-FTT, by aggregating all the providers including food warehousing enterprises, food processing enterprises and food retails to reach agreements and conclude business transactions on the chain, then an unbroken food supply-chain can be formed to provide trusted food tracing. Implementation and experiments are conducted to evaluate the performance of the proposed demonstration system.
