I don’t know.
I saw some people bringing this as an hypothesis today on X.
It makes sense to me that blockchain could allow looking back to previous versions of a given piece of content up to its original source.
For that to work in practice, we would need a new kind of certificate authority (CA) that holds and controls all sources of content for a given celebrity or public person.
Mainstream/Social media and other platforms would have to partner with those CAs in order to guarantee the content they are serving come from legit sources, thus is not an unauthorized deep fake — as we know that image enhancements will continue to exist to keep celebrities forever young and beautiful.
I’ve made this sketch with an idea for validation and posted on X.
