Agricultural Products Supply Chain Traceability System Based On Blockchain

Along with the rapid development of agricultural product supply chain and Internet information technology and the increasing living standards of people,people pay more and more attention to the safety and accuracy of digital information in agricultural product supply chain.Driven by negligent supply chain management and profit-seeking,problems such as counterfeiting and adulteration of agricultural products inevitably appear in front of people and continue to erode people's trust in the traceability system of agricultural product supply chains.How to apply decentralized networks to agricultural product supply chain systems and provide effective and reliable agricultural traceability is an urgent problem to be solved.Based on the decentralization of blockchain technology and the inability of blockchain's data to be tampered with,this paper has conducted in-depth research on the application of blockchain technology in agricultural product supply chain traceability,aiming at the problem of low traceability in the prior art,a solution is proposed,and the design and implementation of the agricultural product supply chain system based on blockchain is completed.The main innovations of this paper are as follows:Improved the tracing efficiency of traditional agricultural product supply chain ased on blockchain.The traceability scheme adopted by the traditional lockchain-based traceability system requires multiple traversal of all the blocks n the entire blockchain,so the tracking efficiency is relatively low.The new raceability method formed by the combination of reverse order search and ecursive algorithm can greatly improve the efficiency of agricultural product raceability.A traditional database was introduced in the improved traceability scheme to ssist in the traceability of agricultural products.Due to the retroactive efficiency f improved traceability scheme is greatly affected by the last transaction position f agricultural products,so it's retroactive efficiency is relatively unstable.The ntroduction of traditional database as auxiliary storage for agricultural producttraceability will greatly improve the stability of traceability;Based on the above two points,the design and implementation of the trace chain ystem of the farm chain supply chain based on blockchain was completed.The system can realize the traceability of agricultural product supply chain,traceability information verification,agricultural product production registration,agricultural product receipt registration,agricultural product supply chain participant registration,login and identity authentication.The main modules include the following modules: user module,function selection module,traceability module,data pushing module and display module.
