Design And Implementation of a Blockchain-Based Certificate Management System for the Office of the Registrar of Cavite State University – Trece Martires City Campus

Abstract

It is essential for educational institutions to possess efficient, transparent, and dependable administrative services that manage student information and certificates. The Office of the Registrar is responsible for maintaining confidential records, including grades, registration details,

and certificates. However, when these offices are required to perform tasks manually and on paper, they encounter numerous challenges. Traditional methods frequently result in errors, delays, and susceptibility to tampering, thereby diminishing the reliability of academic records and impeding

service delivery. At Cavite State University—Trece Martires City Campus, computer systems remain incompatible, and certificates continue to be distributed manually. Emerging technologies

such as web-based tracking, automation, and blockchain have been considered potential solutions;

however, options remain limited at present. Typically, they concentrate on one aspect or the other,

but never concurrently.

Smart contracts, blockchain technology, and the idea of making computers run themselves are what the answer is based on. Three things work together to keep them safe and healthy. The blockchain is what the system is built on. Student records are safe from fraud and cannot make any changes since this is under the use of blockchain, tampering credentials is not accessible in this system. This system assures the user that they process the request for the right owner of the credentials. It also easier to do administrative tasks, it lessens the manual work for the registrar employee all the process is automated, faster work and more accurate process. The Registrar's Office can add information of the students to process the request of the certificates in blockchain- based certificate management system since it is the safe way to get the request of the student. On the blockchain check credentials quickly and since the system are created with blockchain, smart contracts, and automation, the certificates cannot be tampered. It will gain more trust to the university transaction in terms of releasing student credentials. The risk of fake certificates goes down, and it easier for students and employers to check them and it helps Cavite State University – Trece Martires City Campus to have a better manage certificates.

The ISO/IEC 25010:2011 software quality model was utilized to thoroughly evaluate the system, with feedback gathered from students, registrar staff, and IT experts. As anticipated, the acceptance scores remained high, falling within the "Excellent" range. The system received an average score of 4.85 from students, indicating that it performed well in terms of user interaction, safety, and security. However, it could benefit from the ability to integrate with other systems and adapt to changing circumstances. Registrar employee rating the system with a high average score of 4.96, reflecting their strong approval. They rated it highly in safety, dependability, functionality, and performance, suggesting confidence that it would enhance operational efficiency at the institution. IT experts provided a mean score of 4.95, praising its safety, security, ease of maintenance, and flexibility. They proposed strategies to improve its functionality and performance. A Cronbach's alpha of 0.870 indicates that the evaluation tool demonstrates high reliability, making it trustworthy. Overall, the results affirm that the blockchain-based certificate management system is safe, reliable, and effective. Consequently, it is suitable for immediate implementation in educational institutions to meet their long-term needs.

The results indicate that the blockchain-based certificate management system is a reliable, secure, and effective method for tracking academic records and digital credentials. It effectively meets user needs by ensuring that the processes for issuing and verifying certificates are accurate, transparent, and difficult to alter. This technology safeguards records against unauthorized changes, thereby enhancing data integrity. Additionally, it streamlines and accelerates transactions

at the Registrar's Office, increasing overall efficiency. The consistently high ratings from students,

registrar staff, and IT experts demonstrate a strong confidence in its functionality, user- friendliness, and technical performance. This overwhelmingly positive feedback suggests that the system is both practical and suitable for real-world application. In summary, the results indicate that the system is ready for implementation in educational institutions, with opportunities for continued improvement to maintain its usefulness, adaptability, and reliability over time.
