Idle thought:

1. Hacked social media account + deepfakes will be used to fake a coup

2. Cryptographic signatures from a Secure Enclave associated with a public profile on another service provider will be a quick way to refute

seems to me advanced nation-states US/China/Russia are all incentivized not to set this up. maybe makes sense for smaller + tech advanced, like Taiwan or Estonia

there's a meta-problem of how do you prove the proof. Plenty of people already truly believe no moon landing, birds are not real, election was stolen, etc.
