Application And Research On Traceability Of Agricultural Products Based On Blockchain

In recent years,the safety of agricultural products,green organics,and the growth information of all processes of the agricultural life cycle,such as the planting process,growing environment,and quality of agricultural products,have become a topic of widespread concern.The traceability of agricultural products has become one of the important ways to query the growth information of all products.At present,the traditional agricultural product traceability has the following deficiencies:(1)The traceability results are solidified,and the effective traceability of the existing people’s needs has not been performed.(2)The traceability data is stored in the central database,and there is a risk that the data will be tampered with.(3)There are many links in the traceability of agricultural products,each link exists independently,and there will be asymmetric information.(4)Without tracing the source of the crop growth process,it is impossible to know accurately whether the farmer has made the corresponding farming operation.The existence of the above problems leads to inefficient,unsafe,and unrealistic traceability,further distrusting existing traceability schemes for agricultural products.In response to the above problems,this article proposes a blockchain-based agricultural product traceability scheme and establishes a smart agriculture traceability platform.This source tracing system is based on the hierarchical structure in the blockchain system,which increases the additional requirements for the traceability of agricultural products.Aiming at the problem of solidification of traceability results,people’s needs were effectively analyzed,and a MCGM(Meteorological Crop Growth Model)model was established,which effectively combined with agricultural meteorological information to obtain the growth quality characteristics of crops.The blockchain system itself has distributed storage,tamper-proof,and traceability characteristics,making the entire source-tracking data more reliable and the source-tracking results more realistic.The hierarchical structure of the blockchain system in this article adopts the idea of alliance chain for role management.Each traceability link is added to the system through the account authentication system,and data is shared under the corresponding rules.In order to improve the accuracy of the traceability system,in combination with the Internet of Things technology,the solar energy camera is used to dynamically collect agricultural operations and crop growth pictures at the source of agricultural products.For such larger picture information is not suitable for direct chaining,this article will adopt IPFS(Inter Planetary File System)and blockchain technology complement each other to jointly maintain and query data.Throughout the source tracing process,a blockchain-based decentralized source tracing system has been established,and the unique source tracing source is affixed to each agricultural product,so that users can achieve one thing and one code through source tracing,and trace the entire process from farm to table.The application and research of the traceability of agricultural products,establish a smart agricultural traceability platform on the web end,provide related personnel with equipment and data management platform,so that users and authorized personnel can effectively trace the origin of agricultural products through this platform.This paper proposes a model for the traceability of agricultural products,as well as research on the content,which improves the transparency,authenticity and reliability of traceability information.In order to solve some problems of traceability of traditional agricultural products,new ideas and effective solutions are provided.
