With the global shift from the Information Times (IT) era to the Data Times (DT) era, the effective and secure utilization of data has become a prominent goal. In the United States, data brokers have been embraced, while Europe has established the International Data Space (IDS), representing two distinct models for data application. In China, the focus is on transforming data elements from costs to assets through data commercialization and assetization. Within this context, the Trusted Data Space (TDS) plays a crucial role in facilitating the trusted and secure circulation of data. By exploring the business logic, technical requirements, and potential applications, we can evaluate the value proposition of blockchain technology in China’s data element development.

随着全球从IT（Information Times)时代进入DT(Data Times)时代，如何有效安全利用数据成为追逐的重点。美国通过数据经纪人，欧洲通过IDS（international data space）形成了两个分支的数据应用模式，中国在数据要素上在围绕数据市场化和资产化的角度发展数据要素从成本到资产的转化，其中可信数据空间成为构成数据可信安全流转的关键，我们通过介绍中国数据要素发展过程的业务逻辑，技术要求以及应该方式，看区块链技术在数据要素中的价值呈现。
