| Anhui famous tea has significant economic and social values,and whether its production and processing meet national safety standards has always been a concern for consumers.The tea supply chain system can effectively monitor the quality and safety of tea.However,traditional tea supply chain systems face problems such as data centralization,dubious information authenticity,data sharing difficulties,and accountability issues.Establishing a transparent and data-sharing tea supply chain system has research significance and practical application value.Blockchain technology features decentralization,tamper-resistance,and end-to-end traceability,and thus,this paper designs a multi-party participation,end-to-end monitoring,and transparent data Anhui famous tea supply chain system,incorporating blockchain technology.This paper explores the principles and characteristics of blockchain technology,and based on the business process of Anhui famous tea supply chain system,constructs a blockchain network based on the Hyperledger Fabric platform.Using a B/S architecture and a design method of front-end and back-end separation,a three-layer model system architecture of data access layer,data core layer,and data presentation layer is designed.The data access layer accesses data to the core layer through web front-end and Io T technology.When data is accessed through Io T,encryption and integrity verification are performed to ensure the security and integrity of data.The data core layer is responsible for data storage and management.The blockchain data is managed by smart contracts written in Go language.Due to the lower efficiency of reading data in the blockchain,an on-chain local dual-storage mode is used,and the uniqueness of the hash value is utilized to obtain data from the database,and the efficiency of data query is improved by comparing the hash values in the blockchain.The data presentation layer uses front-end languages,such as CSS and JavaScript,to write web pages.The Anhui Famous Tea Supply Chain System has achieved functions such as tea information entry,link management,and tea traceability.In this system,various parties in the supply chain,consumers,and government regulatory departments participate in the management of the tea supply chain,ensuring the openness,transparency,and controllability of data throughout the process.This study effectively addresses the problems of traditional tea supply chain systems by combining blockchain technology,ensuring the quality and safety of Anhui Famous Tea,enhancing the brand value of famous teas,and playing a positive role in promoting the development of Anhui’s tea industry. |
