Wait just a second! You have a bridge for sale? Tell me more.

I could sell you a virtual deed to the Golden Gate Bridge right now, you could buy it but it doesn't really mean anything.

Yeah, that's possibly the most famous scam in history (people selling deeds to the Brooklyn Bridge), enough to where "I've got a bridge to sell you" is a figure of speech for calling someone gullible or naive.

And then despite the world knowing about the Brooklyn Bridge scam, the cryptobros actually went and found a bunch of suckers to fall for the exact same scam, only with blockchains instead of notary seals.

The virtual deeds would be great for game licences and trading second hand games online

I mean we use fiat currency

the issue isnt that it is virtual

I guess the problem NFTs try to solve is authority holding the initial verification tied to the video. If it’s on a blockchain, theoretically no one owns it and the date/metadata is etched in stone, whereas otherwise some entity has to publish the initial hash.

In other words, one can hash a video, yeah, but how do you know when that hashed video was taken? From where? There has to be some kind of hard-to-dispute initial record (and even then that only works in contexts where the videos earliest date is the proof, so to speak, like recording and event as it happens).

With your scheme you can't prove the timing of when the hash was made, nor who made the hash. At the very least the camera would have to include something that proves the time in the hash, and then sign the result with a private key that can't be extracted from the camera.

This is correct.

This is a flaw i had considered and never found a solution for. Hence the idea is unfinished.

The only further argument i have is that manipulating camera techniques is as old as film yet it’s the digital tools that are causing the most harm and allow any troll to partake. Staging a scene takes at least some dedication and effort.

If such would be considered on the blockchain than it would also bring in questions all other footage by the same recorder device. “Wallets” from established authors, anonymous or not would have their own reputations of trustworthyness.

There are decentralized oracles. That's how DAI tracks the price of USD.

This is a very legit concern. But to my understanding, it is possible to make the the camera that's very hard to crack, by putting security enclave or whatever it is that makes phones hard to unlock, right inside the CCD chip. Even if somebody manages to strip off the top layer, chart out the cryptographic circuit, probe the ROM inside, etc and extract the private key, it should be possible upon finding it to revoke the key to that camera or even the entire model and make it even more painful in further models.

Another concern is of camera being pointed to the screen with a fake image, but I've searched and yet to find a convincing shot that doesn't look like, well, a photo of a screen. But for this concern I think the only counter-measure would be to add photographer and publisher signatures to the mix, so that if anyone is engaging in such practice is caught, their entire library goes untrusted upon revocation. Wouldn't be completely foolproof, but better than nothing, I guess.

A private key would be built in to the camera. It would be stored in a way that's hard to get at, physically or in software (like the secure enclaves in phones).

The pics or videos are signed using the private key (again, this process needs to happen in a secure way without revealing the secret key).

The camera manufacturer publishes the matching public key. Anyone can use it to verify that the file matches the signature. But no one can sign a fake image unless they can get at the private key.

This would work even if the camera manufacturer no longer existed. The camera does need to ever be online.

The public/private key pairs are also part of what makes blockchains work, but for this process blockchains would add nothing.

Did you reply to the wrong comment?

The problem is “misinformation” and has been since before nft/genai became a thing.

Gen Ai makes misinformation worse but the event that sparked this was a gop shared video of a democrat which was slightly speed up to seem more aggressive.

Also simple framing to cut off context from the original has been a very common form of misinformation for decades.

That was the marketing hype.

They were actually selling numbered receipts of art prints.
