OK, so i was reading some post on r/chatGPT on reddit. What i took fom it is that basically, some of the people that have historically been Ai video experts and could identify Ai generated video are starting to fail at it. So it's not really a stretch to assume that by 2030, enayone with a brain should expect all videos to be fakes...

One easy way to fix that would be to be able to have every video be signable by identities so individuals can attest they are in there. Otherwise the video could/should not be trusted in 2030..

Then, any individual can not choose any keypair to sign this. There has to be some centraizedl way to ensure that a privkey is a given public person.. But that public person has to be able to sign this with a key that even that central entity can not have.

Come derived keys (BIP32).

A user should be assigned an identity by it's state. Only the states and the individial would know th eprivate key. And the public key would be the users'sz notional Identidt card number.

Then, a user should be able to derive a random key pair from base identity, and sign elements with that derived private key, in a way that proves that the user with the base identity pubkey has certified their identity in the document..

It seems that, this would onlty be possible with 'non hardened' derived keys. To be able to prove that a key is derived from the base private key atributed by the state, without using the state's provider private key directly (but then how do you prove it's you and not the state that derived that key?).

Now, i guess, continue my showerthought?
