摘　　要：为降低数据交易过程中gas的消耗,提高交易平台的交易执行效率,引入区块链技术,设计基于区块链技术的数据交易平台。首先,将数据交易平台划分为4个层次,完成对平台架构的设计;其次,认证可信数据源,并对交易访问用户授权;再次,针对区块链上的数据和区块链外的数据,分别完成安全审计;最后,根据用户需要,实现数据需求匹配与交易。实验结果表明,设计的交易平台可有效降低交易过程中gas的消耗,并以此促进交易执行效率提升。In order to reduce the gas consumption in the data transaction process and improve the transaction execution efficiency of the transaction platform, the Blockchain technology is introduced, and a data transaction platform based on the Blockchain technology is designed. Firstly, the data trading platform is divided into four levels to complete the design of the platform architecture. Secondly, the trusted data source is authenticated and the transaction access user is authorized. Thirdly, for the data on the blockchain and the data outside the blockchain, complete the security audit separately. Finally, according to the needs of users, realize data demand matching and transaction.The experimental results show that the designed trading platform can effectively reduce the gas consumption in the trading process, and thus promote the efficiency of transaction execution.
