Assume deepfakes become widespread. What’s the long term solution?

Perhaps every source of information will need to use digital signatures to establish provenance.

To impersonate the person, you would need to steal their (crypto?) private keys. Not impossible, but harder.

There are legitimate uses of this kind of tech for special effects, entertainment, or VR avatars.

Some of the second order consequences include widespread distrust in any “remote” sources of media. If it’s not from your tribe with multiple levels of auth, assume it’s fake.

Crypto digital signatures can also be used to prove financial alignment.

Does the person sending this message have a lot of the same timelocked crypto that I do?

If so, perhaps more trust — though only if defrauding a fellow hodler would reduce value of their holdings.

It’s interesting to see if you could use financial alignment + reputation to incentivize truthful comms.

Perhaps some form of on-chain altruistic punishment for fraudulent actors. Burn X of your coins to burn Y of theirs?

Makes both fraud and false accusations of fraud costly.

The game theory for something like that is complicated, but there might be a solution.

One thought is the fraudulent actor could threaten to do the same thing back. Burn X of their coins to burn Y of yours.

But then they would lose money too. That would be expensive griefing.
