Design and implementation of food supply chain traceability system based on Hyperledger Fabric

Establishing a credible food traceability system is an effective way to solve food safety problems. While most existing blockchain-based traceability systems are not convincing because the traceability information stored on the chain is just coming from one single organisation. Without the upstream and downstream trading information of the supply chain, even blockchain-based systems with immutability and transparent credibility advantages cannot guarantee accurate traceability for customers. We establish a food supply chain traceability system called FSCTS which aggregates all the enterprises and organisations along the food supply chain to make deals and transactions on the blockchain. Through analysing the trading data associating the whole food circulation from production to consumption, reliable transaction-based traceability can be achieved to provide trusted food tracing. We implement the system on the base of Hyperledger Fabric and prove the effectiveness and superiority of FSCTS by conducting extensive comparison experiments with some similar traceability systems.
