Blockchain-Based Educational Certification Systems Using a Modified Hash Algorithm

EasyChair Preprint no. 12528

Abstract

Blockchain is a crucial digital technology in information technology (IT) and other fields. The use of blockchain is growing because it uses encrypted and distributed databases related to transactions, making it difficult to modify, hack, or check. The education sector uses both on-site and online systems. The use of blockchain technology in education is still in its early stages of development. In this study, we propose secure certification system for educa-tional applications has been presents that based on blockchain technology, which safely sends data over an untrusted network by encrypting the author-ization and certification information using blockchain and modifying the SHA3 algorithm . The potential benefits of blockchain technology in educa-tion certification include improved efficiency, security, and transparency of the educational system. The proposed system uses the back-end and Post-greSQL to save process information for institutes so that it can manage pro-cess information for students. For the front-end, we use React, type, tail-wind, and web3, and build pages and connecting logics. This certification will be added to the student’s wallet address in such a way that only certified students can see their certification and, if needed, check it by third. The re-sults show that the proposed certification model that utilizes blockchain achieves a high level of security in all tests used.
