说明：  为解决农产品追溯系统中出现的数据易篡改问题，利用区块链的相关技术，提出了基于联盟区块链的农产品追溯系统架构模型，比较了该系统架构在网络结构、数据存储和数据管理方面的优势，解决了因有中心而易受网络攻击的问题，提高了系统的鲁棒性、数据的可信度和可靠性; 同时结合实际案例论证了该系统架构实际应用的可行性。
(Aiming at the problem of data tampering in agricultural product traceability system, this paperproposed an agricultural product traceability system architecture model based on alliance blockchain byusing the relevant technology of blockchain,and compared the system architecture in network structure,data storage and data management.The problem of being vulnerable to network attacks due to the centerwas solved.The robustness of the system,the credibility and reliablity of the data were improved.At thesame time,the feasibility of the practical application of the system architecture was demonstrated incombination with actual cases.)
