What about the same url? Or one with query parameter adds? What's to prevent another NFT from pointing to the same data and copying the hash?

- phire 5y agoThe centralised marketplaces themselves (like OpenSea) are able to and might try to police duplicate NFTs, or other counterfeit near-matches. I'm not actually sure if they actually do. But on the blockchain itself, the NFT is just a smart contract (bit of code, bit of data) that knows it's current owner, it's name and a URI pointing at the image. There zero mechanism preventing duplicates. Hell, it's such an unregulated market that the NFT might be based on a custom smart contract with a backdoor that allows the creator to steal it back at any time.

- solarmist 5y agoOk, yeah, that's what I thought. So someone could sell a multimillion-dollar NFT, then someone else could duplicate it manually and "re-sell" it, and if they didn't do proper due diligence...
