Traceability of animal products based on a blockchain consensus mechanism

Block chain technology has the characteristics of decentralization, distributed storage, open and transparent, consensus mechanism, security, information encryption, anonymity and so on. It provides an important way to realize the value added of modern animal supply chain This paper studies the blockchain related technology, an optimization scheme of sBFT consensus algorithm is proposed, and then the optimization scheme is applied to traceability of animal product quality and safety, which solves the problem of decentralization of traceability system and improves the efficiency of consensus in the case of large data input of traceability system. Then, based on Fabric framework, this paper proposes the design and implementation scheme of traceability system for aquaculture industry chain, which can ensure that the participants of traceability system can not tamper with and modify the aquaculture records, and realize the security, reliability and unforgeability of traceability information. Finally, this paper builds a 12-Node block-chain network test environment based on four cloud servers. Under the same test conditions, the sBFT algorithm, PBFT algorithm and dBFT algorithm are tested and compared, and the function and performance of the traceability platform are tested, which shows that the system is feasibility and efficiency of the schemes designed in this paper.
