基于区块链的有机蔬菜认证与溯源方案研究张冠湘崔金银蔡文学龚丽萍摘要为了解决有机市场的有机作假和有机认证效率低下等问题，利用区块链技术的不可篡改、去信任化和分布存储等特性，提出基于区块链技术的有机蔬菜认证與溯源模型。论述有机市场存在的问题，并研究相关领域的国内外发展现状;分析有机蔬菜认证与溯源的数据基础，构建其认证与溯源系统模型，设计基于有机认证的智能合约;并与中心化系统对比，分析模型的优势;以购买假冒有机标识和数据作假2个情景为例，分析模型在解决有机作假和提高认证效率的效果。关键词区块链;有机蔬菜;农产品;有机认证;溯源S126;TS201.6A0517-6611（2019）24-0222-04doi：10.3969/j.issn.0517-6611.2019.24.066ResearchonOrganicVegetableCertificationandTraceabilitySchemeBasedonBlockchainZHANGGuan-xiang，CUIJin-yin，CAIWen-xueetal（DepartmentofEconomicsandCommerce，SouthChinaUniversityofTechnology，Guangzhou，Guangdong510006）AbstractTosolvetheproblemsinorganicmarketslikeorganicfraudandinefficientcertification，theorganicchaincertificationandtraceabilitymodelbasedonblockchaintechnologywasproposedbyusingthecharacteristicsofblockchaintechnologysuchasnon-tampering，de-trustinganddistributedstorage.Theproblemsintheorganicmarketwerediscussed，andthendevelopmentstatusofrelatedfieldsathomeandabroadwasstudied.Afteranalyzingthedatafoundationoforganicvegetablecertificationandtraceability，thecertificationandtraceabilitysystemmodelwasconstructedandtheintelligentcontractbasedonorganiccertificationwasdesigned.Thesystembasedonblockchaintechnologywascomparedwiththecentralizedsystem，andtwoscenariosofbuyingcounterfeitorganicidentificationandcounterfeitdataweretakenasexamplestoanalyzetheadvantagesandeffectofthesystembasedonblockchaintechnology.Theresultshowedthatthesystemcouldsolvetheproblemoforganicfraudwell，improvetheefficiencyoforganiccertificationandmaketraceabledatamorecomplete.KeywordsBlockchain;Organicvegetable;Agriculturalproducts;Organiccertification;Traceability作者简介张冠湘（1975—），男，湖南郴州人，副教授，博士，从事农产品冷链、危险品物流等研究。*通信作者，硕士，研究方向：从事农产品冷链。-全文完-
