The invention relates to a Hyperledger Fabric-based traceability system and method, the system comprises a plurality of block chain nodes and a data block, the plurality of different block chain nodes receive data at least output by a producer, a storage party, a transport party and a seller, a supervision department obtains supervision data from the different block chain nodes, and the data block receives the supervision data from the producer, the storage party, the transport party and the seller. Consumers perform steel information tracing from different block chain nodes; and after the input information is judged to be legal through the smart contract, the blockchain nodes are chained, transaction information is synchronized through the blockchain nodes, block generation is carried out, and consensus blockchain data is formed. The method has the characteristics of decentration, openness, tampering resistance, traceability and the like, and can effectively solve the problems of information counterfeiting,
