videos need to be cryptographically signed and able to be verified. all news outlets should do this.
The NFTs tried to solve this problem already and it didn’t work. You can change the hash/sig of a video file by just changing one pixel on one frame, meaning you just tricked the computer, not the people who use it.
so try again? also: if a pixel changes then it isn’t the original source video, by definition. being able to determine that it has been altered is entirely the point.
The point was to sign AI footage so you know what’s fake. NFTs can be used as a decentralized repository of signatures. You could realistically require the companies to participate, but the idea doesn’t work because you can edit footage so it doesn’t match the signature. More robust signatures exist, but none is good enough, especially since the repo would have to be public.
Signing real footage makes even less sense. You’d have to trust everybody and their uncle’s signature.
The signing keys could be published to DNS, for better or worse.
What would that solve? NFTs don’t have to be powerhungry proof of work, that was just for the monkeys. The public ledger part of this is not the problem.
How can an organization prove that a given key is theirs using NFTs?
A digital signature works with public/private keys and content hashes. This is a solved problem.
In fact, it’s part of secure DNS.
