Trusted Traceable NFT for Certificates

This paper introduces a blockchain-based non-fungible token (NFT) for any type of certificate, such as patents, international and national conferences, poems, contents of social media, etc. These documents may be altered or modified, so by creating a NFT’s certificate, we can simply keep a record of the digital form. Blockchain and NFT certificates can be trusted and securely traceable without any alteration or modification. In this work, we analyzed the potential for using NFTs using both types of public and private blockchain. We also present the proposed framework and implementation details for secure, traceable certificates. The results show the NFT is a feasible solution for any kind of digital certificate.
