基于区块链技术的种子溯源体系研究

Research on Seed Traceability System Based on Blockchain Technology

针对目前传统种子溯源防伪体系处于中心化的管理运作方式,数据信息维护整合较困难,存在种子育、繁、销不同环节的信任问题的状况,本研究通过对传统溯源技术的比较分析,从物理层、数据库层、网络层、应用层对数据输入、数据查询和系统应用环节进行了探讨,设计了基于区块链技术的种子溯源防伪体系,以实现种子在培育、运输、销售环节中信息记录的防篡改、可追溯性,并通过去中心化的网络特性解决种子溯源防伪体系中存在的数据信任、维护和孤岛等问题。

Considering that present traditional anti-counterfeiting systems of seed traceability adopt the centralized management and operation mode, data information is difficult to maintain and integrate, and there are some trust problems in the links of seed breeding, reproduction and marketing, this study investigated the links of data input, data query and system application from the physical layer, database layer, network layer, application layer through the traditional technique of traceability system, and designed a seed source anti-counterfeiting system based blockchain technology to realize the tamper proof and traceability of seeds when they in the links of cultivation, transportation, sales to solve the seed source anti-counterfeiting system’s problems of data trust, data maintenance, and data island.
