Research On Traceability System Of Forest Ecological Food Supply Chain Based On Block Technology

This article integrates blockchain technology with the traceability of forest ecological food supply chains to develop a traceability system with decentralized,tamper-proof,and traceable features.Through this research,it efficiently and securely addresses the pain points and challenges faced in the current traceability of forest ecological food supply chains.It also resolves the traceability and regulatory issues of forest certification products in the forest certification project,enhances the market competitiveness of enterprises,consumer trust in products,and enables secure and transparent product supervision.Firstly,a forest ecological food supply chain traceability model based on blockchain technology is established.To address the issues of data security,efficiency,and convenience in traceability,traditional traceability systems such as barcodes,QR codes,and RFID are abandoned,and the synchronization technology of NFC(Near Field Communication)tags is combined with the blockchain network.Secondly,regarding privacy protection within the traceability system,a multi-chain business structure with a synchronous verification module is proposed.It establishes a multi-channel communication structure within the blockchain and creates private data models in channel nodes to isolate data from different nodes.Finally,based on the Hyperledger Fabric network technology,smart contracts are developed using the Go language at the business layer,and the backend is coupled with the beego rapid development framework to quickly develop user account management modules,including functions for publishing and querying forest ecological food information.Through system testing and functional verification,the research results are as follows:(1)The system achieves decentralized distributed storage of data.The distributed ledger structure of blockchain provides a low-cost and secure data recording and verification mechanism for the supply chain traceability system model.It can eliminate information asymmetry and trust issues,ensuring data authenticity and immutability,and enhance trustworthy cooperation and coordination among supply chain participants.(2)The system implements a more secure and efficient data verification mechanism.By utilizing the NFC capabilities of mobile communication devices to recognize the NFC encrypted labels on product packaging,users can view traceability information.This solves the issues of easy replication and tampering with QR codes and barcodes,as well as the additional cost of purchasing dedicated recognition devices for RFID tags.(3)The system implements privacy protection for the flow of product information among different participants.In the functional design,a multi-chain business structure is provided for all participants in the forest ecological food supply chain,ensuring the need for reasonable business secrets among supply chain participants.(4)The system ensures the permanent and complete storage of data in the traceability system.All the circulation information of forest ecological food within the supply chain is recorded on the blockchain,and the data is distributed in different databases.This avoids the risk of compromising the entire circulation information due to the damage or theft of a single database.This study explores the traceability of forest ecological food supply chains based on blockchain technology.By utilizing this research,it can enhance the security and efficiency of forest ecological food in the supply chain.It provides reasonable and effective solutions for production,transfer,sale,and purchase aspects,and offers practical exploration of blockchain technology in the field of traceability for forest ecological food.
