But this would only make it unique on the CENT blockchain, no? What if another blockchain becomes the standard offerer, wouldn't that devalue everything on the CENT blockchain? Further, wouldn't we expect multiple blockchains to be competing to become the "primary" chain in which these items are deemed valuable, i.e. CENT and blockchain A & B & C trying to be the medium which holds a unique cert to Jack's first tweet. Jack's first tweet has a unique copy on each blockchain, but being that each chain has it's own NFT of jack's tweet, the digital certificate of the tweet is not necessarily unique. Or is twitter supposed to maintain their own blockchain that creates NFTs for each of their tweets and users are going to assign the most value to this chain since it's maintained by the company itself? Further, I don't understand how this works in music/art. Grimes' copy of her music is issued on Nifty Gateway, but isn't that art only valuable as long as users assign value to the Nifty Gateway platform? What stops another art blockchain from becoming more desirable/valuable and creating a NFT of Grimes' art there? Doesn't that erode the value of the original NFTs? What am I missing here?
