基于区块链技术的种子溯源体系研究

目前传统种子溯源防伪体系的现状是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。为此，本文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研究，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。

Research on Seed Traceability System Based on Block Chain Technology

At present, there are many problems in the traditional anti-counterfeiting system of seed traceability, and it is difficult to integrate the centralized traditional management and operation mode and data information maintenance. At the same time, there are trust problems in different links of seed breeding, reproduction and marketing. To this end, this article through to the traditional technique of traceability system adopted by comparison and analysis, the design technology based on block chain seed source of security system, from the physical layer, database layer, network layer, application layer of data input, data query and research design, the system application link to in order to realize the seeds in the cultivation, transportation, sales link information recorded tamper-proof, traceability, and features in decentralized network to solve the seed source anti-counterfeiting system problems in the data island.
