摘要

为解决现有主流区块链共识算法易造成政务数据共享出现再中心化问题，形成符合交通运输信息化建设实际的区块链技术框架下政务数据共享方案，提出了一种基于FCM-DPoS的交通运输政务数据共享模型。首先，基于区块链技术设计了交通运输政务数据共享模型，明确了模型主要角色和数据共享关键流程；然后，提出了FCM-DPoS共识算法，使模型更好地实现去中心化的数据共享；最后，与现有模型进行对比，分析所建模型的技术特点和优势，并通过仿真模拟实验验证FCM-DPoS共识算法的可行性。实验结果显示，所提共识算法产生的出块节点空间分布与国家级数据枢纽节点地理分布特征基本一致，其中35.8%的出块节点出自节点计算能力较低地区，这表明FCM-DPoS共识算法可有效保护节点计算能力较低地区的出块权利，降低了因节点计算能力空间布局不均衡造成模型中心化的风险。

Abstract

In order to solve the problem that the main consensus algorithm of blockchain would cause the re-centralization of government data sharing, and form a government data sharing scheme under the blockchain technology framework conforming to the actual situation of transportation informatization construction, this paper proposed a transportation government data sharing model based on FCM-DPoS. Firstly, a transportation government data sharing model was designed based on blockchain technology, and the main roles of the model and key data sharing processes were defined. Secondly, the FCM-DPoS consensus algorithm was proposed to make the model realize decentralized data sharing. Finally, by comparing with the existing models, the technical characteristics and advantages of the proposed model were analyzed, and the feasibility of the FCM-DPoS algorithm was verified by simulation experiments. The experiment results showed that the spatial distribution of outbound nodes generated by the proposed consensus algorithm was basically consistent with the geographical distribution characteristics of national data hub nodes; the 35.8% of outbound nodes came from regions with low node computing power, which indicated that FCM-DPoS consensus algorithm could effectively protect the outbound rights of regions with low node computing power and reduce the risk of model centralization caused by uneven spatial layout of node computing power.
