Nonfungible token (NFT) is an item on the blockchain that is completely unique and unique, compared to classic digital files that can be copied. These are mostly images or videos, but in a way, almost anything can be created as an NFT. NFT tokens thus solve the problem by certifying the item and marking it with the original. When an NFT token is purchased, the owner will be registered on the blockchain and gain access to the purchased digital item, which can be anything.
