A NFT or non-fungible tokens are blockchain-based unique and irreplaceable tokens that each represent a unique asset like a piece of art, digital content, or media. In contrast, a traditional exchange of value like cash can be exchanged for another. NFT then can be thought of as an irrevocable digital certificate of ownership and authenticity for a given asset, whether digital or physical. There initial base value is linked into the huge amount of computing power and energy cost necessary to create them legitimately or hack the algorithms illegally, plus of course any overriding premium or discount associated with hype or trends in the marketplace.
