Careless disposal of dead or sick livestock seriously affect environmental sanitation and human food safety.There are many challenges for centralized monitoring of traditional traceability processes based on RFID networks.This paper proposes blockchain technology to monitor the network for dead or sick livestock,improving monitoring effectiveness and trust in the system.A decentralized structure is employed to overcome drawbacks evident for traditional supervision processes and ensure process credibility.Reduced loss from contract fraud is achieved by minimizing the opportunity for malicious or accidental events through intelligent technology.Security and stability of the system is guaranteed by employing a distributed database based on a P2P network.Application of blockchain technology for monitoring dead or sick livestock can greatly improve monitoring,system pressure,government credibility and public trust,and avoid potential safety problems caused by illegal processing.
病死害动物随意丢弃和流入市场会严重影响环境卫生与食物安全,传统基于射频识别(radio frequency identification,简称RFID)技术溯源流程构成的中心化监控网络,存在诸多挑战。将区块链技术引入病死害动物的监控网络,有效提升了监控效力与群众信任度,主要体现在:(1)采用去中心化结构,克服了传统监管流程存在的弊端,确保流程可信度;(2)通过智能合约技术最小化恶意或意外事件发生的可能性,降低合约欺诈所造成的损失;(3)采用基于对等网络的分布式账本数据库,保证系统安全稳定。将区块链技术用于病死害动物监控,能极大地提升监控效果、政府公信力、群众安全感,避免农户及非法处理机构不自觉所导致的安全隐患。
