SO WHAT IS AN NFT? WHAT DOES NFT STAND FOR?
NFT stands for Non-fungible token.
With that out of the way lets explain more.
The part “Non-fungible” means that it’s unique and can’t be replaced with something else. For example, a bitcoin is fungible — trade one for another bitcoin, and you’ll have exactly the same thing. A one-of-a-kind trading card, however, is non-fungible.
How do these 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 like WAX or SOL.
