摘要
我国冷链物流具有环节多、链条长、耗损大等特点,难以形成较大规模的冷链物流网络,所以亟需高水平的信息技术提供支持,提高物流的数据和管理效率,解决节点端资源信息不对称的问题。在区块链中无论何种机制都是通过去中心化的共识算法来保证信任问题的,所以基于区块链共识机制的应用场景是解决终端客户信任问题的关键。文章基于PBFT算法提出了冷链运输系统的模型,在考虑共识效率的基础上,将模拟仿真引入PBFT算法的冷链运输系统与传统型的有效共识完成率进行比较,得出在节点增加的情况下,将基于PBFT算法的冷链运输系统的有效共识完成率明显高于传统型冷链运输系统。研究结论有利于提高冷链运输的可靠性和稳定性,为制定冷链物流中的安全策划提供了重要参考,对于大规模改善我国冷链物流体系、扩大冷链物流规模具有重要意义。
China's cold chain logistics is characterized by multiple links,long chains and high consumption,which makes it difficult to form a larger-scale cold chain logistics network.Therefore,there is an urgent need for high-level information technology to provide support,improve the efficiency of data and management in logistics,and solve the problem of node end resource information asymmetry.In blockchain,no matter what mechanism is used,the trust problem is ensured by decentralized consensus algorithm,so the application scenario based on blockchain consensus mechanism is the key to solve the trust problem of end customers.The paper proposes a model of a cold chain transportation system based on the PBFT algorithm,and simulate and compare the effective consensus completion rate of cold chain transportation system introduced by PBFT algorithm with the traditional type on the basis of consensus efficiency.It is found that with the increase of nodes,the effective consensus completion rate of the cold chain transportation system based on the PBFT algorithm is signif icantly higher than that of the traditional type cold chain transportation system.The research findings are conducive to improving the reliability and stability of cold chain transportation,providing an important reference for formulating safety planning in cold chain logistics,which is of great significance for improving the cold chain logistics system and expanding the scale of cold chain logistics in China on a large scale.
