Issuing and managing diplomas and certificates using blockchain technology
The authors of Ho Chi Minh City Polytechnic University have built a system for granting, managing diplomas and certificates, and applying Blockchain technology. This application helps to reduce the time and cost of training facilities; at the same time detecting fake cases quickly.


Currently, certificates and diplomas are mainly issued by training institutions in physical form (paper, polymer, etc) with many shortcomings, such as wasting storage space; the possibility of loss or damage is high; easy to fake. The verification of qualifications and certificates is also very time consuming, often hours, even weeks. Therefore, if there is a way to quickly and conveniently verify certificates, fake diplomas and certificates will no longer have a chance to exist.

Before that fact, the authors of Ho Chi Minh City Polytechnic University made the project "Application of blockchain technology in the allocation and management of degrees and certificates." The team has developed a certificate digitization system and provided a decentralized way of verifying digital certificates without having to go through the issuer. The system includes procedures for issuing, revoking and verifying certificates on mobile devices or websites.

To issue a certificate, the training institution registers the account and logs in the system to generate the embryo. After filling out the information of students, courses, and etc. the institution can issue a certificate (print) or number. Each certificate is issued with a QR code, which can look up and verify student information and certificates on mobile applications. The system also has features for students to view detailed information about certificates, courses, training centers. At the same time, it can manage the list of certificates. The institutions attended, places used certifications.

The system has been piloted in the Center for Computing Engineering of Ho Chi Minh City Polytechnic University in issuing and managing certificates of architecture and interior design classes. More than 100 students get a certificate with only about 2 seconds per certificate.
