The White House wants to 'cryptographically verify' videos of Joe Biden so viewers don't mistake them for AI deepfakes

This is a most excellent place for technology news and articles.
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.
Wouldn't this be defeated by people re-uploading the video? I think all these sites will re-encode the videos uploaded so the hash will not match, then people will use that as proof that the video is not real.
