You could be asking yourself, “What is an NFT?”
“Non-fungible” basically indicates it’s one-of-a-kind and can’t be substituted with anything else. A bitcoin, for example, is fungible, meaning you can exchange one for another and get precisely the identical thing. A one-of-a-kind trade card, on the other hand, cannot be duplicated. You’d get something altogether different if you swapped it for a different card.
Most NFTs are, at a high level, part of the Ethereum blockchain. Ethereum, like bitcoin and dogecoin, is a cryptocurrency, but its blockchain also enables these NFTs, which store additional information that allows them to function differently from, say, an ETH coin. It’s worth mentioning that various blockchains can use NFTs in their own ways.
NFTs can be anything digital (drawings, music, even your brain being downloaded and transformed into an AI), but the current buzz is focused on exploiting the technology to sell digital art.
NFTs are intended to provide you with something unique: ownership of the work (though the artist can still retain the copyright and reproduction rights, just like with physical artwork). To put it another way, anyone can buy a Monet print in terms of tangible art collecting. However, the original can only be owned by one person.
