摘要
基于区块链的数据共享有助于推进跨地域、跨系统、跨主体之间的数据共享,让数据提供方放心、数据监管方省心、数据使用方小心,真正促进数据价值流动,实现数字政府。通过分析现有数据共享政策及应用需求,提出基于区块链的数据共享解决方案,从数据发布、数据共享访问控制、数据评价等多个维度设计智能协议,并对相关协议进行了测试验证,给出了实验数据。此外,也从技术维度分析了基于区块链的数据共享解决方案的发展趋势,为后续研究和系统建设指明了方向。
Blockchain-based data sharing helps to promote cross-regional,cross-system,and crosssubject data sharing,so that in the process of data sharing,the data providers can be at ease,the supervision process is simple,and the data users can use carefully.This can promote the flow of data value,and realize digital government in high-speed.A data sharing solution based on blockchain through analyzing the existing data sharing policies and application requirements is proposed.Then,an intelligent protocols from multiple dimensions such as data release,data sharing access control,and data evaluation is designed,the related protocol is tested and verified,and the experimental data is given.In addition,the development trend of data sharing solutions based on blockchain is analyzed from the technical dimension,which points out the direction for follow-up research and system construction.
