摘要: 农农业是我国的支柱产业,构建安全、可信、稳定、可溯源、信息共享、大吞吐量的农业供应链系统是实现我国农业信息化的必经之路。然而,我国农产品供应链中的信息通常存储在中心化的数据库和数据系统中,面临着管理能力弱、容易被窃取、篡改、删除和信息不一致等问题。基于上述问题,论文结合星际数据系统和智能合约技术,建立了面向农产品供应链中异构信息数据的高效抽取方法,实现含有农产品生产管理、运输记录、消费者信用管理、农户-消费者交易服务的大型异构信息事务日志的快速抽取,并将各类信息事务日志及交易记录分别存储至区块链和 IPFS 网络;提出了基于区块链智能合约的农产品供应链信息数据访问控制方法,结合基于IPFS 哈希寻址的访问方式,能够有效的保障不同的农业生产经营参与主体用户在各自的权限范围内访问数据;在此基础上,设计了一种基于区块链技术的农产品供应链数据管理系统,系统具备异构信息数据可信管理功能,可以确保整个供应链进行充分安全透明的可信任信息共享,促进农产品产销无缝衔接、推动农业转型升级、助力农民脱贫增收。
