It absolutely doesn't. OpenSea (and others) has hundreds if not hundreds of thousands of stolen art pieces traded daily.

> Go make a counterfeit BAYC. Then try and sell it.

There's literally a fight now between two counterfeit bored apes ripoffs over which one is legit.

There's zero provenance in NFTs. They have zero relevant information on an art piece. Yes, if you are lucky to be somewhat famous you can tell people what is and isn't yours. Otherwise: no. You could yourslef figure out why.

Hints, if you can't:

- NFTs have zero relevant information on an art. They don't even contain the art itself, they point to a URL that hopefully hosts the art itself

- NFTs have zero information on the original owner of the art and whether that person has any rights to own and sell the art
