Study on the Trustable Circulation of Scientific Data in the"Technology Innovation Golden Triangle"of Chengdu-Chongqing-Mianyang:Based on the Technical Perspective of Blockchain and Federated Learning
Based on the technological empowerment perspective of the integration and innovation of blockchain and federated learning,this paper constructs a scientific data sharing system for the Chengdu-Chongqing-Mianyang"Technol-ogy Innovation Golden Triangle",aiming to provide technical support for promoting the open sharing of scientific data among the three parties,in order to adapt to the large-scale demand for multi-source heterogeneous data in scientific re-search intelligence;and on the basis of clarifying the existing obstacles to scientific data sharing,explores the technical mechanism of"blockchain + federated learning"empowering trustable sharing of scientific data,and elaborates on the specific implementation paths from three aspects of model exchange,data calculation and incentive mechanism;and ac-cording to the research results,points out that the sharing system not only has trustable features of blockchain such as traceability,tamper resistance and decentralization,but also has the privacy protection function of federated learning's"model moving while data no-moving",and still has some new features derived from the integration and innovation of these two technologies,which can be summarized as security and reliability,privacy protection,scalability,and automa-tion incentives,thus allowing the scientific data held by all parties to participate in large-scale collaborative computing without leaving the domain,which helps to mobilize the enthusiasm of stakeholders and provides digital platform support for the joint production of scientific knowledge.
