A non-fungible token (NFT) is a unit of data stored on a digital ledger, called a blockchain, that certifies a digital asset to be unique and therefore not interchangeable. NFTs can be used to represent items such as photos, videos, audio, and other types of digital files.
WHAT IS AN NFT? WHAT DOES NFT STAND FOR?
That doesn’t make it any clearer.
How do NFTs work?
At a very high level, most NFTs are part of the Ethereum blockchain. Ethereum is a cryptocurrency, like bitcoin or dogecoin, but its blockchain also supports these NFTs, which store extra information that makes them work differently from, say, an ETH coin. It is worth noting that other blockchains can implement their own versions of NFTs. (Some already have.)
What’s worth picking up at the NFT supermarket?
NFTs can really be anything digital (such as drawings, music, your brain downloaded and turned into an AI), but a lot of the current excitement is around using the tech to sell digital art.
In economics, a fungible asset is something with units that can be readily interchanged – like money.
With money, you can swap a £10 note for two £5 notes and it will have the same value.
However, if something is non-fungible, this is impossible – it means it has unique properties so it cannot be interchanged with something else.
It could be a house, or a painting such as the Mona Lisa, which is one of a kind. You can take a photo of the painting or buy a print but there will only ever be the one original painting.
NFTs are “one-of-a-kind” assets in the digital world that can be bought and sold like any other piece of property, but they have no tangible form of their own.
The digital tokens can be thought of as certificates of ownership for virtual or physical assets.
