As far as I can tell, most of the NFTs that have broken into popular consciousness are entirely non-public and nobody can verify or inspect them at all. I spent like an hour yesterday trying to figure out which blockchain, specifically, the $69M Beeple NFT is on; nobody seems to know, and nobody really seems to be asking.

It is currently safe to assume Ethereum with the file stored on IPFS. Christie's interface didn't just lead with the transaction hashes, but your conclusion is pretty far off, for now. Try emailing them next time. I'm understanding of the frustration, it took me a year of asking similar questions about Venezuala's Petro coin, which was even subject to pre-emptive US sanctions, before it became official that the Petro didn't exist and was never issued. Nobody could tell me the contract address and people acted like I grew two-heads for even asking, when it should have taken two seconds. The technology allows for really basic things to be transparent, and when you don't lead with that stuff and nobody asks about that stuff, it does become pretty obvious that they aren't even using the technology.

  The Petro coin was a weird one though much about Venezuela's economy is weird these days.

  Thanks. That does seem to be it.

  What's odd is that the listing on Christie's references a larger christies.com-hosted version of the JPG (3000x3000), here: https://www.christies.com/img/LotImages/2021/NYR/2021_NYR_20447_0001_001(beeple_everydays_the_first_5000_days034733).jpg?mode=max https://www.christies.com/img/LotImages/2021/NYR/2021_NYR_20... Whereas the IPFS version of the image is merely 1200x1200. In this case, it really matters because the image is a mosaic that is virtually indecipherable at the 1200x1200 size. So, it begs the question what is the person actually buying? I get that it's the concept of "ownership" that's being sold, but ownership of what exactly? When the new owner then goes to sell "it", what do they reference? An illegible JPG?

    No, the 21069x21069 URL is there in the token, too, if you just find the "raw_media_field" field: https://gateway.pinata.cloud/ipfs/QmPAg1mjxcEQPPtqsLoEcauVedaeMH81WXDPvPx3VC5zUz/ https://gateway.pinata.cloud/ipfs/QmPAg1mjxcEQPPtqsLoEcauVed...

      Ah, I see. Thanks. Yeah, interesting that this notion of ownership is separate from IP. And, of course anyone can download the file itself. So, they're essentially selling the right to declare you own it and the ability to sell that right to someone else.
