Research And Implementation Of Academic Record Storage And Sharing Svstem Based On Blockchain

With the continuous development of blockchain technology,there are more and more areas of application using blockchain technology.However,the application of blockchain technology in the field of academic storage and sharing is still in a relatively short stage.With the continuous increase of data volume,the existing academic record system using blockchain technology is often inefficient and unreliable in the process of record storage.While in the process of record sharing,there will be problems of poor security and sharing pertinence.Based on the blockchain technology,this thesis proposes a blockchain model based on the joint data segmentation algorithm and a label sharing method of academic record,designing and implementing a feasible system of academic record storage and sharing.It realizes a complete process of academic record storage and sharing,and proposes a feasible solution to the problems of low efficiency of record reliable storage under large data volume and poor pertinence of record security sharing.First of all,this thesis investigates the current research situation about the academic record storage and sharing system based on blockchain,and introduces the related technologies and methods about this system.Then the system requirements are analyzed in detail to determine the main functional requirements and corresponding performance indicators of the whole system.In addition,aiming at the two key problems in the process of academic record storage and sharing on the blockchain,this thesis proposes a blockchain storage model based on the joint data segmentation algorithm and a label sharing method of academic record.And then the overall design of the system is completed by describing the static structure,dynamic structure and data structure of the system.After that,according to the genetal design,the implementation process and details of the system function module are described in detail,in which the implementation method of record storage and sharing on the blockchain is highlighted.Finally,the function and performance of this system is tested and giving a complete test report.
