This is fairly gross, pretending to be socially concious when if the technical claims were true it would be a horrific potential for abuse (revenge porn etc).

NFT's have nothing to do with ownership, if someone puts up your data illegally or even just breaking copyright, get the police / a lawyer involved and they will take it down, luckily NFTs are heavily centralised so it wont be difficult.

The funny part is the image itself isn't even on the blockchain, it's centrally hosted somewhere. The token is just a pointer. You can ruin it by having the actual content taken down, wherever it is.

The Interplanetary File System is a decentralized solution.

True, but my comment that the image isn't on the blockchain is still accurate. IPFS is not a blockchain and content can be changed.

Doesn't IPFS use content-addressing? In other words, the url of a file is the hash, so the contents can't be changed.

correct

Can it not be removed by the original uploader, or anyone else to acquire their credentials?

Interestingly enough, most NFT would disagree with you as long as they are backed by content-addressable systems. What do you mean with that "NFTs are heavily centralized"? The metadata itself is stored on Ethereum or similar while the actual bytes of the media is stored in IPFS. How is that centralized?

Who is pinning it?

Some digging shows that tweet is totally misinformed. He seems to think that because niftygateway's json response returns an internet-facing url, that the underlying NFT must also be referencing an internet-facing url (as opposed to an IPFS url/hash). This is incorrect. The URL he's seeing in the API response is simply a IPFS proxy service offered by the NFT website. If you extract the identifier of the NFT from the url he linked[1] and plug it to etherscan[2], then scroll down to "trumpVictoryIPFSHash", you can see that the NFT is actually referencing the IPFS hash directly, and not the internet facing url. You can confirm this by plugging that value into an IFPS gateway[3]

TIL that NFT would have been different if Trump had won.

The responses to that thread go into more detail, but I'll ask the more direct and pertinent question:

IPFS requires someone to pin the data - who will be doing that going forward? The platform? The artist? The owner? Thus far, it isn't anyone's responsibility to make sure the IPFS hash returns.

> NFT's have nothing to do with ownership,

Exactly! Finally someone said it. I really don't understand these people selling NFTs of a vase or a framed artwork.

If I obtained that vase legally (by payment in USD or BTC or whatever) and it's sitting in my apartment then I own it by default. Someone else can have an NFT for it if that makes them all giddy and happy but at the end of the day it's my vase, it's staying in my residence, and I can do whatever I want with it.

Maybe I should start selling some NFTs for a blue pixel on my screen. Seems like a good cash cow opportunity since it seems that people love to "digitally own" (whatever that means) things that they don't have and that other people actually own.

I've wondered about this. Is there a reason you can't store a text encoded image on the actual NFT?
