ABSTRACT

When the students have finished their studies, their numerous certificates of excellent performance, score transcripts, diplomas, etc., will be an important point of reference for entrance to other schools or positions. Only the names of the schools and the students are included when schools create different prizes or diplomas. Events that lead to the graduation certificate being forged are frequently discovered since there is no reliable anti-forge system. The blockchain-based digital certificate system would be suggested as a solution to the issue of certificate forgery. The blockchain's capacity to be modified makes it possible to create digital certificates with anti-counterfeit and verifiability. In this system, issuing digital certificates is done in the manner listed below. Create an electronic file of the paper certificate first, along with other pertinent data, and while doing so, determine the hash value of the file. The hash value should then be added to the block in the chain system. To be attached to the paper certificate, the system will generate a linked QR-code and an inquiry string code. The solution not only increases the legitimacy of diverse paper-based certificates, but also significantly lowers the chance of certificate loss because to the blockchain's changeable qualities.
