摘要
"民以食为天",但频繁发生的食品安全事件,引发了人们严重的信任危机。针对如何从技术层面保障食品安全这一目的,本文通过将区块链技术与食品溯源技术结合的方法,设计了基于区块链的食品安全溯源体系结构。其中包含场景设计、系统架构、去中心化设计和共识机制,并详细阐述了所设计体系结构的运行机制。通过对实际案例进行分析和验证,得出所设计方案具备实际可行性和有效性。
Hunger breeds discontentment,but frequent food safety incidents have triggered a serious crisis of people's confidence.Aiming at how to technically guarantee food safety,block chain and food traceability technologies are combined together,and a food safety traceability system architecture based on blockchain is proposed,which is comprised of scenario design,system architecture,the core idea of decentration and consensus mechanism,and the detailed operation mechanism of the system.Finally, the feasibility and effectiveness of the designed scheme are demonstrated by specific application case.
