Design and Implementation of Blockchain-based College Education Integrity System

Abstract

The paper firstly takes the requirements of the college education integrity system (CEIS) issued by the local education authority as the research object, proposes a restricted blockchain model with auditing and its consensus algorithm, and then proposes two improved MPT tree search algorithms to improve the search efficiency. Finally, the system adopts the Ethereum blockchain for system design, implementation and verification. The system is deployed in the NodeJS, with the Truffle framework to configure and write smart contracts to create decentralized DApp. The front-end is built with LAYUI, and the back-end is written in Solidity for smart contracts. MongoDB and Redis are used for data interaction with DApp. Ganache is used to build an Ethereum simulation network for system testing and realize the application and transfer of Ethereum in units of accounts. The blockchain-based college integrity system can solve the problems of high cost, low efficiency and data reliability risks in centralized systems.
