At its simplest, NFTs allow you to sell digital items in the same way you sell physical items. NFT stands for non-fungible token. Fungible means mutually interchangeable, or able to replace or be replaced by another identical item. So a "non-fungible" item is unique and cannot be replaced by an identical item; there is no identical item. Using blockchain technology, the digital item (your media) is converted into a unique, trackable, secure asset. This part creates the 'token'. Unlike images you find in a search online, your original media is essentially transformed into a singular item. It can't be copied, unless you define that you want to generate a specific number of tokens. That works like "prints" of art, where you sell 200 of 200 prints and they're numbered 1, 2, 3, etc. This process creates scarcity in the same way a single painting is scarce, and so is more valuable.
