A Secure and Trustworthy Cross-Domain Data Aggregation Platform

The rapid growth of the data-centric digital economy is driving an increased demand for data infrastructure that effectively manages data as a core asset, accommodating its unique attributes while facilitating its flow, use, and maximizing its value. This study aims to explore a Blockchain-based Secure and Trustworthy Cross-Domain Data Aggregation Platform (STCDAP). The platform is designed to create a secure and reliable data service system through its unique architectural design, including modules for data transfer, management security, data services, business services, and computing power services, providing comprehensive support for the development, circulation, and utilization of data resources. The application of STCDAP demonstrates its potential in promoting the sustainability of the data economy and serves as a key infrastructure in the data market.
