Title: Let&#x27;s say I&#x27;m the owner of the nyan cat NFT (I&#x27;m not). Is there anything that prevents someone from duplicating the nyan cat and putting it on another blockchain? If not, does the uniqueness of my nyan cat (which is on Ethereum, I believe), rest on the assumption that one blockchain will be the defacto NFT implementation, and the rest won&#x27;t be taken seriously?
