The sad thing is the concept wasn’t.
Selling NFTs with no physical existence is what is pointlessly stupid.
Before they came along i considered the idea of a blockchain linked video camera where metadata of footage gets written into the chain to combat fake news and misinformation.
The goal would be to create a proof and record of original footage, to which media publishers and people who share can link towards to verify authenticity/author.
If the media later gets manipulated or reframed you would be able to verify this by comparing to the original record.
It was never a finished idea but when i first read nft i thought this is the right direction.
And then capitalism started selling apes and what the actual disgusting money possessed fuck was that.
This is actually a pretty decent idea considering what's coming now with AI video. I have no idea if it could be implemented, or if media even cares anymore, but I sure would appreciate it.
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.
Even if people can't get the key out of rom, which I doubt, they can man in the middle the cable going to the photosensor and inject arbitrary images into the system.
