Core Viewpoint - The event hosted by Tsinghua University Internet Industry Research Institute focused on the launch of the DataRocks trusted data space product solution, addressing the core pain points in the current data factor market and promoting the safe circulation of massive data [2][4]. Group 1: Policy and Market Demand - The era of developing trusted data resources for urban construction has begun, with the key to digital urban development being the development of the data factor market [5]. - The DataRocks solution aims to overcome three major barriers in data value release: invisible cross-domain data, inaccessible high-value resources, and sensitive data that is not utilized [5]. - The National Data Bureau's action plan aims to establish over 100 trusted data spaces by 2028, emphasizing the need for trusted control, resource interaction, and value co-creation [5]. Group 2: Core Technical Advantages of DataRocks - DataRocks leverages Tsinghua University's research in trusted data spaces and combines it with Bubi Technology's blockchain, privacy computing, and DID (Decentralized Identity) technologies to create its core capabilities [6]. - The solution utilizes a fully controllable blockchain platform to ensure data transaction integrity through on-chain evidence and smart contracts [7]. - Privacy computing technology allows for controlled data sharing, ensuring data sovereignty while releasing data value [8]. - The integration of DID with CA technology provides a unique global identifier for data subjects, enhancing identity security and facilitating safe data circulation [9]. Group 3: Key Functions of DataRocks - DataRocks encompasses a comprehensive product design that covers the entire data circulation chain, including trusted infrastructure, connectors, and data services [13]. - Key functionalities include DID identity management, data encapsulation and secure publishing, smart contract signing, and full lifecycle traceability, creating a closed loop for data value circulation based on trusted governance [13]. Group 4: Application Cases - The DataRocks solution has supported the construction of multiple trusted data spaces, providing end-to-end support from data registration to security supervision [14]. - In industry-specific applications, it connects banks and government entities, utilizing privacy computing to combine loan data with social security and business data for enterprise credit scoring, with over 10 banks already integrated [14]. Conclusion - The DataRocks solution represents a significant breakthrough in building trusted infrastructure and exploring intelligent production and living models, transforming dormant resources into powerful drivers for an intelligent society [15].
