Abstract In recent years, food safety problems have become increasingly serious.
The traditional supply chain traceability solution faces some serious problems,
such as centralization, data tampering, and high communication costs. To solve
these problems, this paper proposes a food traceability framework based on
permissioned blockchain. The proposed framework is decentralized, and the supply
chain data of the framework cannot be tampered with. The framework divides
supply chain entities into five organizations, and each organization deploys its own
chaincode onto the blockchain. The chaincode specifies the query permission of
each organization, which can effectively protect the user’s sensitive information.
