A non-fungible token, also well-known as an NFT, is a kind of cryptocurrency token that works similarly to a digital certificate of ownership of physical or virtual assets. These tokens are unique, non-fungible digital identifiers, so they are not a payment method. They are used for buying, selling, and exchanging unique items. I.e., paintings, photos, texts, music, and videos. NFTs differ from other crypto tokens, they are unique, unlike common crypto tokens, where the token is traded on a decentralized exchange, whereas in the case of NFT, assets are traded on a special exchange called the NFT marketplace.
