Application of Blockchain in Academic Credit Bank System

Abstract

The essence of blockchain is decentralized and distributed ledger/database technology. Blockchain has the advantages of decentralization, Safety and tamper-proof, traceability, openness and transparency and anonymity. Blockchain technology can effectively deal with the various problems and challenges faced by traditional academic credit bank. In the application scenario of learning achievements deposit, the blockchain technology can avoid import errors or tampering of learning achievements and increase the authority and credibility of the academic credit bank. Automatically executed smart contracts can improve the efficiency of depositing learning achievements into the academic credit bank, reduce labor work and save time. In the application scenario of job application and recruitment, through blockchain, job applicants and employers HR no longer need to re-confirm the certification authority from the certificate issuing institution to achieve the purpose of data confirmation and data verification, which improves the efficiency of job application and recruitment. In the application scenario of academic credit transfer, the use of smart contracts + Oracle for academic credit transfer can effectively integrate students’ academic competence information spread across multiple data sources, and improve the efficiency and authority of the academic credit bank system. A three-step strategy can be used to build a blockchain on the academic credit bank system, followed by private chain, alliance chain and public chain. In this paper the account-based blockchain model is preferred rather than the transaction-based blockchain model to be used in the academic credit bank system.
