Genuinely asking: how? They seem, to me, to be a hype driven thing that doesn't make sense. If I buy an NFT of an art piece, what's stopping others from downloading the same file?
It's not about having access to content, but about owning the "thing". You might buy a painting and post high resolution scans of it: good enough for people to make very convincing copies. But it doesn't affect the ownership of the thing.
NFT is not so much the content, but a record of ownership on the blockchain. And for digital content, that "doesn't make sense" outside of digital realm, it's a very natural tool to produce ability to own something digital.
I’d like that on my own tweets, to start.
Claim of ownership is overrated.
It's just a record on a blockchain.
It is trivial to fork said blockchain, and have a conflicting claim setup on the fork.
It’s harder to fork the Ethereum blockchain in the same sense that it’s hard to convince people to accept factorial bucks over old fashioned USD.
FYI I'm not a huge crypto person, I don't know if the above is trustworthy, but it's an example of what you could do. God's knows if it works or collapses in a fire, but it's fun to watch.
