“区块链+物联网”助推食品供应链溯源

“Blockchain+Internet of Things”Boosting Traceability of Food Supply Chain

目前,食品信息数据面临可靠性差、来源性广和鉴别性难等问题,亟需信息技术的支撑作用。通过对3种开发框架的对比分析,利用FISCO BCOS开发了食品溯源体系,利用RFID实现有效的信息溯源,区块链技术保证每个环节的信息数据安全,物联网技术实现源头数据的智能化管理。设计了软件整体框架和"链上+链下"多源数据存储模式,呈现"客户端+移动端"溯源查询,实现食品供应链溯源系统的再造,提升食品溯源效率。

At present,food information data is facing problems of poor reliability,wide sources,and difficult identification.It urgently needs support of information technology.Through comparative analysis of three development frameworks,food traceability system was explored by using FISCO BCOS.RFID was used to achieve effective information traceability.Blockchain technology was used to ensure security of information and data in each link.Internet of Things technology was used to achieve source intelligent management of data.Software framework and multi-source data storage mode of"chain up+chain down"were designed,which showed traceability query of"client+mobile terminal",realized reconstruction of traceability system of food supply chain and improved efficiency of food traceability.
