Design And Research On The Teaching Information System Based On Blockchain

With the development of Internet technology and information technology,digital teaching information system brings many conveniences for information storage,transmission and authentication.However,the existing teaching information system stores data in a centralized database,which has weak anti-risk ability for network attacks,and internal managers can also erase the modification trace after tampering with the data.In order to solve the problems above,this paper applies block chain technology to decentralized storage of teaching information,and studies the design and implementation process of teaching information system based on block chain.The research contents of this paper are as follows:(1)Comparing and analyzing the concepts of centralized management and decentralized management,pointing out the shortcomings of the centralized storage scheme of educational information,and analyzing the shortcomings of the existing block chain teaching information system.(2)Design a four-tier application architecture composed of block chain layer,contract layer,data interaction layer and application layer by choosing appropriate block chains and traditional web technologies.(3)Design and develop the block chain learning letter recording module and depository evidence collection module,realize the input and query of relevant information on the block chain,ensure the security of information and reliable traceability.(4)Design and develop an open autonomous community based on the idea of decentralization.Users can participate in community content management and construction while communicating in the community.(5)Design a schemes of test cases and stress test,tested the function and performance of the system,and analyzed the test results.(6)Analyze the shortcomings of the system and prospected the scheme to improve the system.In summary,the teaching information system based on block chain,which is designed and developed in this paper,takes advantage of the characteristics of de-centralization of block chain technology and permanent preservation of data traces,records teaching information and related operation records,has the advantages of safety,reliability and traceability,and explores the application of block chain technology in the field of education.
