A Research On Key Technologies Of Data Capitalization Based On Blockchain

The openness and circulation of data sharing is an implementation method to enhance the ability to accumulate the value of static data and convert it into dynamic assets.Through data sharing and exchange between industries,a multi-dimensional and rich digital economy industry can be built.Under the idea of data as the core,the security and convenience of data in the process of sharing and exchange,as well as the consideration of multi-party rights and interests,will directly affect the willingness of all parties to cooperate in this economic and industrial form.In the current solution,more data is gathered in a centralized storage network,and the data is obtained through remote calls.This solution has the problems of difficulty in data synchronization,high storage and maintenance costs,and a high risk of data leakage.To this end,this thesis takes the construction of a data asset network as the core goal,and uses the principle of blockchain,a trusted system,to research and implement a trusted data transaction network with blockchain as the bottom layer and container technology as the upper-layer data asset sharing network.It describes the key technologies involved in the whole process of the assetization link in the scheme,and finally presents the ability of data to improve assetization through secure sharing and exchange,which plays an important role in the ownership of the assets of all parties involved.The main research work of this thesis includes:（1）The basic theoretical knowledge involved in data security sharing and exchange is studied and the overall requirements are clarified.By analyzing and summarizing the existing data exchange technical achievements and combining the existing demand scenarios,the key processes and technologies of the overall data sharing and exchange network proposed in this thesis are characterized,including network and system-level design,data assetization definition of the whole life cycle,etc.（2）Analyzed the actual problems encountered in the existing scenarios with blockchain as the key underlying technology,and proposed targeted solutions.According to the performance of the blockchain and the requirements of the network environment,a data tunnel based on a 4-layer network is implemented and a consortium chain dynamic sharding technology is designed to improve the transaction performance in a large-scale node network.（3）The key technologies involved in the data network realization process of the core link of data assetization are studied.The assetization process is divided into three steps: data in-situ supply,data application remote deployment,and data dynamic transaction.The key technologies involved in each step are researched and implemented,and verifiable solutions are presented in a sequential description.（4）The key technologies involved in the proposed scheme are tested.The simulation software was used to test the underlying blockchain performance optimization model to prove the feasibility of the optimization direction;the upper-layer data container network was functionally tested to ensure the effectiveness of the key technologies of the overall scheme.
