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?

This is the argument that gets me applied to bitcoin. It's first mover advantage. And the "gold2.0" market value is this perceived incorrectly if there is no other moat. That's why today we are announcing ... Bitquan!

That's correct. Which makes it all even more absurd. Although the smart contracts are there forever, so at least it can't "go bust" (although the web front-end certainly could).

> it certifies ... that there will never be another certificate for the same thing, from the same brand of certificates (e.g. "Valuables BY CENT").

How many "brand of certificates" are there now, and what is the barrier to entry?

I suspect 1) several and 2) low.

Also, how is "there will never be another certificate for the same thing, from the same brand of certificates" technically enforced?

> Also, how is "there will never be another certificate for the same thing, from the same brand of certificates" technically enforced?

A Merkle chain[0] append-only ledger contains a transaction minting the certificate, and the consistency rules for that Merkle chain mean that any extension of the chain which mints another such certificate is not valid (the same as a extension that spends money from a account with no money in it is not valid).

0: technically a blockchain specifically, but that's not actually relevant

Correct. Although there is only one brand that has sold a Tweet NFT for $3mil.

The enforcement, interestingly, is more traditional; the owners of the "Valuables by CENT" trademark can use existing legal structures to prevent anyone else using that name.

Meanwhile the NFT is digitally linked to the Valuables by CENT smart contract on Ethereum, which will presumably have an 'author' property attached to it, set to the string "Valuables by CENT".

Ah, so they pinkie swear not to do it a second time?

It would be equivalent of Sotheby's starting a second brand competing with themselves, but yes.

Sotheby's was founded in 1744 (1). They have a track record, a _brand_ to maintain.

Your average blockchain was founded recently, and have a lot less to lose taking the money and running, or popping up again under a new name, for a second go at the same shtick.

But when you buy a baseball card you get a card. Here it seems that you only get a receipt stating that you have paid (aka the certificate) AND NOTHING ELSE.

If I understand it correctly, that receipt in conjunction with your keys allows you to prove you own the NFT and can control it on the blockchain(sell it, trade it, etc).

But the NFT is the receipt, if I understand correctly. You own a receipt (the NFT), and you can trade it, but why are people buying and selling receipts? You make a payment, you get a receipt, and nothing else, which makes absolutely no sense. Usually, when you buy something you get a receipt for free and then the actual thing that you have bought.

I think at that point the platform upon which the receipt resides will prevent people from making duplicates on their chain, and the owner of the receipt have control over buying/selling it.

And one should be happy to control the receipt of their purchase of imaginary goods? Ok.

Currently, when it comes to Dorsey's tweet? Yeah I agree. But there is more going on and it will not always be "imaginary goods".

If you have essentially bought a jpeg image, you have as much control over it as anyone else: Anyone can view, transmit or edit it, etc. Your "proven purchase" grants you exactly nothing extra.
