摘　　要：针对当前食品追溯系统由于技术标准不统一,信息不透明、易篡改,中心化及信息孤岛严重,追溯系统建设效果不理想这一缺陷,通过探讨食品追溯关键标准与技术,建立了物联网加区块链的食品安全追溯系统架构,设计了食品追溯流程,并采用联盟链模式和超级账本区块链开发平台,实现了一个食品安全追溯原型系统。结果表明,物联网加区块链的技术方案可以提高食品供应链效率和透明度,重建消费者对食品行业的信心。According to the shortcomings of current food traceability system on account of inconsistency in technological standards,nontransparency in information,liability to be tampered,serious centralization and information islands,this paper explores the key standards and technologies of food traceability,establishes a traceability system structure and designs a food traceability process based on Internet of Things and blockchain.By adopting the alliance blockchain model and the Hyperledger development platform,implemented a traceability prototype system.It fully demonstrates that our technological solution can significantly improve efficiency and transparency of the food supply chain,which will obviously enhance the food safety and rebuild the consumer＇s confidence in the food industry.
