I wonder if there's a startup opportunity there. In the coming years, this problem of deepfakes and lack of trust in media is only going to get worse. Crypto could mitigate this. Maybe a hardware company who sells very high end cameras for media outlets, that digitally signs and adds to a blockchain, all recorded media?
But why store the signature in a blockchain? If you do not trust the certificates in the first place, the storage location won't make any difference. And if you trust the certificates, the storage location is completely irrelevant. Because the certificates alone provide the trust.
For the same reason as certificate transparency logs; you want to avoid trusting something that has a history of certifying false statements. You also need to handle throwaways, so it's definitely not sufficient (and might turn out to not be necessary once a complete solution is found), but it does seem useful.
Well, my thinking was that you would want to store the data cryptographically signed, on a block chain, for the same reasons (more or less) that NFTs exist on a blockchain. Predominately, the public ledger of ownership seems like an important aspect of digital content. Is it necessary for trust? Not at all, but it certainly doesn't hurt it?
