Research On Agricultural Products Supply Chain Traceability System Of S Enterprise Based On Blockchain

With the steady development of China's economy and the improvement of people's living standards,the demand for high-quality food is increasing.For the purpose of protecting the legitimate rights and interests of consumers,enhancing the supervision of agricultural product quality and regulating the development dynamics of related industries,the government has introduced a series of policies to regulate the quality and safety of agricultural products and promote the healthy development of the agricultural products market.However,along with the development of the agricultural products market,phenomena such as untimely traceability of problematic agricultural products,lack of traceability platforms and counterfeit and shoddy brands of agricultural products have still emerged,hindering the expansion of the scale of the agricultural products market and the healthy development of the industry,undermining the rights and interests of consumers,affecting the trust of consumers in the regulatory authorities and bringing new difficulties to the regulatory authorities.Therefore,the construction of the traceability system for agricultural products should be carried out,and the information involved in enterprises certified by enterprise qualifications in the supply chain of agricultural products should be uploaded to a credible platform,so that the corresponding information can be traced and queried in a timely manner when problems of agricultural product quality and safety arise,and thus reflected the regulatory authorities in a timely manner,which can greatly improve the speed of locating the source of problems.At the same time,the traceability platform adds the function of certifying the relevant agricultural product brands,so that consumers can check the qualification and information of enterprises from the platform,which is conducive to maintaining genuine agricultural product brands and combating counterfeit and shoddy products."However,with the development of Zhangqiu Baoqin in the market,the brand value has increased and many counterfeit products have been created,with many unscrupulous businesses using poor quality celery to pass themselves off as Zhangqiu Baoqin online and offline.Many unscrupulous merchants use poor quality celery to pass themselves off as Zhangqiu Bao Qin online and offline,and sell poor quality parsley under the slogan of Zhangqiu Bao Qin,which not only damages the reputation of Zhangqiu Bao Qin,but also affects the legitimate rights of consumers.Therefore,the idea of constructing a traceability system for the supply chain of Zhangqiu Bao Qin has arisen from the core enterprise S.The construction of a traceability system for the supply chain of Zhangqiu Bao Qin will not only strengthen the brand certification effect and increase consumers' confidence in the agricultural products of the enterprise but also upload and store information on the whole process of the supply chain of Zhangqiu Bao Qin in real-time,which will facilitate quick accountability in case of quality problems.The construction of a supply chain traceability system for Zhangqiu Bao Qin is therefore of great significance.It is therefore of great significance to build a traceability system for the supply chain of Zhangqiu Bao Qin.Firstly,a detailed analysis of the core enterprises of the Zhangqiu Bao Qin supply chain called enterprise S,including the production(planting and picking),processing(packaging),transportation and sales of Zhangqiu Bao Qin,was carried out to sort out the process of each link and the needs of the participants,and on the basis of the analysis,the needs of each user and the key information on the traceability of Zhangqiu Bao Qin were summarised.The key information on the traceability of Zhangqiu Bao Qin is summarised on the basis of the analysis.In selecting the storage information technology,blockchain technology,which is different from the traditional centralized database,stores enterprise information locally and has the characteristics of a distributed deployment ledger,which solves the insecurity of the central database being attacked,while the consensus mechanism ensures that the data information cannot be tampered with.The above two characteristics make me choose blockchain technology as the information storage technology for the supply chain traceability system of Zhangqiu Bao Qin.Meanwhile,based on the review of relevant literature and platform comparison,the Hyperledger Fabric platform was selected as the blockchain platform to realize the traceability of Zhangqiu Bao Qin.Secondly,this paper proposes the logical architecture of the supply chain traceability system of Zhangqiu Bao Qin based on the alliance chain(an alliance formed by enterprises related to the traceability of the supply chain of Zhangqiu Bao Qin with enterprise S as the core enterprise),and carries out the design of functional modules,smart contracts and consensus mechanisms according to the analysis of the traceability process and system architecture design to complete user audit and information upload and interaction.The ledger is accessed after the user's identity is verified through the smart contract,broadcasting and adding blocks are completed,the transaction applications submitted by the user are completed using the consensus mechanism,the sorting and packaging of transactions are completed,and the synchronous update of the ledger in the state of the world is ensured.Finally,on the basis of the designed traceability system,the various functional modules of the traceability system were developed and implemented by deploying the federation chain environment and building the federation chain network on the Hyperledger Fabric platform,and the effectiveness of the traceability system was verified through the implementation of the upstreaming of information on the supply chain of Zhangqiu Bao Qin and the retrieval of traceability information on the supply chain of Zhangqiu Bao Qin,so as to achieve the objectives of suppressing counterfeit Zhangqiu Bao Qin and encouraging This paper uses "Zhangqiu Bao Qin" as an example to carry out the design and platform simulation test of the supply chain traceability system of Zhangqiu Bao Qin,and verifies the effectiveness,accuracy and reliability of the traceability system.
