摘要
目的:解决传统溯源系统无法保证数据可靠性和完整性的问题,进一步加强对冷链食品的防护与监控。方法:基于区块链技术为湖南省市场监督管理局构建了湘冷链溯源系统,采用读写分离的存储方式,利用缓存系统提升了区块链系统读写状态数据的效率。结果:湘冷链溯源系统实现了湖南省进口冷链追溯环节的数据共享,并且针对发生疑似问题的冷链食品可以精准定位和快速上报。结论:湘冷链溯源系统基于区块链技术可信任性和可溯源性,为湖南省市场监督管理局提供了一种更为安全的冷链食品监管模式,通过追溯环节、追溯码、产品管理以及信息上链防篡改功能,实现了可信闭环冷链食品"物防"追溯体系,保障了食品安全。
Objective: In order to solve the problem that traditional traceability system cannot guarantee the reliability and integrity of data, and strengthen the protection and monitoring of cold chain food. Methods: Based on the trustworthiness and traceability of blockchain technology, the Hunan Provincial Market Supervision and Administration Bureau had built a traceability system for the Hunan Cold Chain. Hunan Cold Chain adopt a storage method that could read and write separation, and used a cache system to improve the efficiency of the blockchain system to read and write status data. Results: Thereby achieving data sharing in the traceability link of the imported cold chain in Hunan Province through traceability links, traceability codes, product management and information. Conclusion: The on-chain anti-tampering function realizes a credible closed-loop cold chain food physical defense traceability system to ensure food safety.
