Research On Architecture Of Digital Educational Resource Management System Based On Blockchain Technology

With the development of Internet technology,education informationization arises at the historic moment.In this process,digital education resources,as the main carrier of teaching in the digital age,are paid more and more attention.However,problems such as repeated construction,centralized storage and low degree of sharing occur in the process of digital education resources construction.How to store and share the digital educational resources and realize the effective management of the digital educational resources has become the main problem to be urgently solved.This research takes the emerging blockchain technology as the breakthrough point,combined with the characteristics of the distributed and traceability of the blockchain technology to propose new research ideas for the storage and sharing construction of digital education resources.This research has mainly done the following three aspects of research:(1)Completed the demand analysis of digital education resource management system.According to the design goal of the digital education resource management system,the positioning of the system is determined.Combined with the needs of different users,the main functions of the system are analyzed.The main functional modules including user management module,resource management module and blockchain management system module are designed.At the same time,it also analyzes the non functional requirements of the system.It lays a foundation for the construction and design of the follow-up digital education resource management system.(2)The overall architecture of Digital Education Resource Management Based on blockchain technology is designed.Combined with the Hyperledger fabric architecture system,this paper designs the network architecture and technical architecture of this study.Then,the overall functional structure of the management system is designed,and the detailed transaction process of the resource management module is analyzed and designed combined with the fabric blockchain data process.Finally,the smart contract and database are described and designed.(3)This paper discusses the practical development of digital education resource management system based on blockchain technology.This paper summarizes three main blockchain development methods,and focuses on the construction of IBM blockchain platform based on Hyperledger Fabric.Through a simple operation example,this paper describes how to add nodes,organizations,channels and other functions in the system,and discusses the possibility of large-scale application and development of digital education resources.In this paper,the blockchain technology is applied to the digital education resource management,and the resource storage and sharing mode of "local resource database + blockchain" is proposed.The construction scheme of digital education resource management system based on blockchain is designed.The system has the characteristics of decentralization,distribution,security and reliability,including the main work modules of digital education resource management.It can effectively improve the degree of digital education resource data management and sharing,and provide a new idea for the construction of digital education resource management system.
