Blockchain Implementation to Ensure the Authenticity and Integrity of Graduation and Diploma Certificates

This research addresses the escalating problem of diploma forgery by proposing a novel, decentralized diploma issuance system powered by blockchain technology. The proliferation of fraudulent credentials undermines the integrity of quality education and necessitates a secure, verifiable mechanism for direct diploma authentication by institutions. This system tackles this challenge by utilizing a distributed ledger, eliminating the need for a central authority, and enhancing credential security. Designed using Solidity and deployed on a private Ethereum network, the system assigns distinct roles: educational institutions issue and manage diplomas, students retain access to their own verified credentials, and potential employers can seamlessly verify their authenticity. Our analysis of gas usage reveals that the initial issuance process on the blockchain incurs the highest cost. However, subsequent retrievals by students or industry stakeholders demonstrate a lower average gas cost, with consumption increasing proportionally to request volume. While the system highlights promising results within a private network environment, the limitations inherent to its small-scale implementation are acknowledged. This research contributes to the field of credentialing by offering a secure and verifiable solution for diploma issuance, fostering trust in quality education, and streamlining the verification process for all stakeholders.
