Research On The Key Technologies Of Building An Integrity Archive Platform Based On Data Sovereign Blockchain

China is keenly aware that blockchain technology plays a particularly important role in the construction of the social credit system.Although the ordinary blockchain technology has realized the solidification of the value transfer process,there is the core problem of unclear ownership of value sovereignty.Especially in traditional integrity platforms,once data owners share data,they lose control of the entire life cycle of the data,which greatly restricts the use and circulation of data on the platform.Aiming at the pain points in the above-mentioned traditional integrity platform,this research content includes: using the opportunity of government data sharing openness and value-added data applications,the establishment of an electronic certificate chain based on the data sovereignty blockchain;combined with the identification and Strong correlation ability to form a cross-industry,cross-business,and cross-domain behavioral record base database;and then build a digital Chinese social integrity archive based on this basic database;finally,through data sharing and management,form orderly management and rational government resource scheduling And a credible archives foundation platform to reduce the risk of various social development.The innovation points of this research are: innovation of the integrity file model based on the three chains,and technological innovation of the data sovereignty blockchain.The significance of this study is to solve the problems of lack of supervision of license information leading to user privacy leakage,low application efficiency of license information sharing,inefficient application of license information,and loss of authenticity of license information,which can quickly improve and enhance government operation efficiency and urban green development.ability.After testing,the integrity system has eliminated the security threats in data transmission,protected the legitimate rights and interests of the data sovereign,and built an innovative integrity system and value incentive mechanism on top of the data sovereign blockchain technology.
