An NFT, fully named Non-fungible token, is a type of "non-fungible token" based on the Ethereum blockchain. Unlike virtual currencies such as Bitcoin and Ether, the most significant characteristic of NFTs lies in their uniqueness; each NFT is one-of-a-kind and cannot be directly exchanged for another. This feature allows NFTs to be associated with specific digital assets, such as a piece of artwork, a music track, or a video clip, thereby becoming "digital assets" owned by the holder.
