Maybe the White House should create a hash of the video and add it to a public blockchain. Anyone can then verify if the video is authentic.
Don’t need to involve a blockchain to make cryptographically provable authenticity. Just a digital signature.
The only thing a hash in a blockchain would add is proof the video existed at the time the hash was added to the blockchain. I can think of cases where that would be beneficial too, but it wouldn’t make sense to put a hash of every video on a public blockchain.
Transparency logs like that are helpful to show when media was first seen / published
