Aquaculture products is an important source of animal protein for human body, and its safety has been widely concerned. In this paper, we design and develop a hierarchical and multi-user aquaculture product quality traceability system by applying gs1-128 bar code standard, PBFT consensus algorithm and hyperledger intelligent contract chain code, and the system is deployed and implemented in Linux environment. The system can provide some functions such as save quality information and traceability query, which can solve the problem of food quality information being opaque and tamable. Thus, consumers will trust food information, and they can quickly trace the source to ensure the safety of aquaculture products when food safety problems arise.
