Development of a Blockchain-Based Tokenization Enhancing Diploma Security, Authenticity, and Verification at Cavite State University – Trece Martires Campus

Abstract

There is a growing need for credible, valid, and efficient certification of diplomas. These needs have exposed some inadequacies within the current diploma management systems, which can be susceptible to forging and inefficient manual verification. This research project proposed a blockchain-enabled diploma tokenization solution that would help manage the security, validity, and verification process at Cavite State University-Trece Martires Campus.

The diploma management platform was developed according to the Input-Process-Output design model. It was developed using the Waterfall development approach. React 18, TypeScript, and TailwindCSS were the technologies used in the development of the frontend. Meanwhile, Express 5 with Passport.js was used for developing the backend. PostgreSQL was used for database management. Blockchain technology integration was done by deploying the platform on the Ethereum Sepolia test network using ethers.js. Diploma hashes were then stored on the blockchain network.

The system was assessed based on factors such as functionality, efficiency, usability, reliability, security, and safety. The outcomes were consistent in showing highly favorable scores described as "Excellent" on all criteria, meaning that the system successfully addressed both user and technical needs.

The findings revealed that blockchain technology greatly enhances the trustworthiness and verification of academic credentials. The system created through this study offers a safe, reliable, and efficient mechanism for handling diploma credentials.
