Hello, I am Rosalino, a software engineer.
In the related article What Is an NFT Diploma? A New Approach to ‘Proof of Learning’ for Educational Institutions the background of why NFT diplomas are gaining attention was explained from the perspective of “proof of learning” in the education field.

However, opportunities to explain how such a system actually works from a technical perspective are still limited.
In this article, I implemented a minimal prototype and organized the flow from issuance to verification in order to examine how an NFT diploma system can be realized. This article explains the mechanism from a technical perspective following the process from issuance to verification.
