In
this thread
, an NFT cryptoart collector with deep pockets named beanie said,
I have bought a few pieces on FND cause they were significantly
cheaper, but now realize they were priced that way for a reason.
SR on-chain provenance is critical for galleries and investors.
The price premium is probably still understated.
and adds
The SuperRare platform is the on chain marketplace, just like Larva
Labs (CryptoPunks).
This is CRITICAL and adds immense value in so many ways.
What does he mean by the
Foundation.app
(FND) platform being off-chain and the
SuperRare
(SR) platform being on-chain? From what I understand, there is no economical way to store 5MB+ jpeg files on any blockchain at the moment so I doubt SuperRare even does what he is claiming. What is he really getting at?
Besides, doesn't FND and SR both upload images to the InterPlanetary File System (IPFS), meaning that they are both off-chain?

As Ismael points to in the comments, it would seem that the author of the linked comment in the OP's question was not pointing to SuperRare being on-chain and Foundation off-chain, but was emphasizing that the value of SuperRare as a curator. The "on-chain" provenance comment likely means that being able to point to an NFTs on-chain history means it can be traced back to where it was purchased from on-chain, and having been in SuperRare is part of what one is purchasing when they purchase such an NFT (in the thread author's opinion.)
There's something we should really unpack here as an additional note on the question: NFTs, according to the ERC-721 (and 1155) standard that they are based on, do not (generally) "include" a JPEG or other image. There is generally a field in the NFT that contains some kind of pointer (if you look at the
standard
, this is the extension called the Metadata extension) traditionally a URL or IPFS (or similar) hash, to a JSON. The JSON, in turn, links to the media. This is very significant, as it means in many cases that the media can become either unlinked (in the case of the JSON pointing to a centralized IPFS gateway,
for example
) or even actively changed (in the case of it pointing to someone's traditional web site,
for example
). That's a bit tangential, but very useful in terms of understanding NFTs.
