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.
