Non-fungible token.
That doesn’t make it any clearer.
Right, sorry. “Non-fungible” more or less 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. If you traded it for a different card, you’d have something completely different.
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.
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. 
We are sure some people really hope so — like whoever paid almost $390,000 for a 50-second video by Grimes or the person who paid $6.6 million for a video by Beeple.
You are a buyer.
One of the obvious benefits of buying art is it lets you financially support artists you like, and that’s true with NFTs (which are way trendier than, like, Telegram stickers). Buying an NFT also usually gets you some basic usage rights, like being able to post the image online or set it as your profile picture. Plus, of course, there are bragging rights that you own the art, with a blockchain entry to back it up. You will be able to buy our NFTs on OpenSea very soon!
NFT ownership is recorded on the blockchain, and that entry acts as a digital pink slip. Where is the blockchain? It’s decentralized, so it exists across many people’s computers in encrypted bits and pieces.
In the technical sense that every NFT is a unique token on the blockchain. But while it could be like a van Gogh, where there’s only one definitive actual version, it could also be like a trading card, where there’s 50 or hundreds of numbered copies of the same artwork.
It’s really simple! Just follow the instructions given on OpenSea platform.
