A non-fungible token (NFT) is a special type of cryptographic token that represents something unique. NFTs are called non-fungible because they are not mutually interchangeable, since they contain unique information, although it is possible to mint any number of NFTs representing the same object. This is in contrast to cryptocurrencies like bitcoin, and many network or utility tokens, that are fungible in nature
An NFT is a unique token living on a blockchain that represents (or points to) some other data, like an image or video. Because they live on a blockchain, NFTs are easy to track. This tracking allows for verification of their authenticity as well as their past history and owners.
