Abstract

Academic credentials such as degree certificates, transcripts, and course completion records are fundamental for validating an individual’s educational achievements. However, conventional credential management systems largely rely on centralized databases and physical documentation, making them vulnerable to forgery, unauthorized modification, data loss, and inefficient verification processes. These limitations reduce trust among educational institutions, employers, and learners, while also increasing administrative overhead. This study proposes a blockchain-based credential authentication framework designed to enhance trust, transparency, and security within the education ecosystem. The proposed system leverages a permissioned blockchain network to record immutable digital fingerprints of academic credentials, while the original documents are securely stored in encrypted off-chain repositories. Smart contracts are employed to automate credential issuance, validation, and revocation, ensuring consistency and eliminating manual intervention. Students are provided with controlled access to their academic records, enabling secure and selective sharing with authorized verifiers such as employers or higher education institutions. A prototype implementation demonstrates that the proposed approach significantly reduces credential verification time while ensuring data integrity and tamper resistance. The hybrid on-chain and off-chain storage model effectively balances security requirements with scalability and storage efficiency. The findings indicate that blockchain technology can address critical challenges associated with traditional academic credentialing systems and offers a reliable foundation for future digital credential management. The proposed framework has strong potential for adoption across educational institutions seeking secure, transparent, and efficient credential authentication mechanisms.

Keywords: Blockchain, credential authentication, digital verification, education technology, smart contracts
