What the heck is an NFT?
Simply put, a non fungible token is anything in a digital form; say an image, a video or a song, with a unique signature that is accounted for by Blockchain technology usually by the cryptocurrency Ethereum. That means a digital picture of a cat or a rat or a hat can be bought or sold with completely verifiable ownership through computer code. Of course there can be copies of this NFT, just like there are copies of a painting, but there is only one original and the NFT, the token, is its statement of authenticity or provenance. The "non fungible" part refers to the item being singular, as opposed to currency, where say one bitcoin or a $100 bill is the same as any other.
