Aren't NFTs essentially just file hashes/signatures that can be associated with a public/private key pair on a blockchain? If so, the link between the NFT and the key pair might be solid (as in cryptographically secure) but the link between the NFT and its "underlying asset" (which might be copyrightable) seems flimsy.

That being said, since both NFT ownership and our legal systems rely on consensus and majority opinion, it's not hard to imagine a corrupt society in which the opinion of judges is disregarded in favor of blockchain consensus.

Edit: you might be joking but it's an interesting question nonetheless because it highlights how various systems compete for legitimacy :)

IANAL

The NFT would be completely irrelevant here. Basically I assume you are claiming copyright over your salary and personal information. Unfortunately you can't trademark facts, so this approach isn't viable.

Try it and let us know!
