NFTs, explained
There’s nothing like an explosion of blockchain news to leave you thinking, “Um… what’s going on here?” That’s the feeling I’ve experienced while reading about Grimes getting millions of dollars for NFTs or about Nyan Cat being sold as one. And by the time we all thought we sort of knew what the deal was, the founder of Twitter put an autographed tweet up for sale as an NFT. Now, months after we first published this explainer, we’re still seeing headlines about people paying house-money for clip art of rocks — and my mom still doesn’t really understand what an NFT is.
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. You gave up a Squirtle, and got a 1909 T206 Honus Wagner, which StadiumTalk calls “the Mona Lisa of baseball cards.” (I’ll take their word for it.)
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.)
