How is a hash of the image supposed to prove anything about when it was created?
You post it publicly somewhere that has a timestamp. A blockchain would be best because it can't be tampered with.
Ah, I thought you were saying the hash proved something on its own. Lots of weird ideas about crypto in this thread.
That proves it existed at a specific time in the past, not that it didn't exist before that. What's stopping a hash of the Mona Lisa on a block chain with today's date?
It also doesn't materialize ponies out of nothing. It can't do everything, but surely you can see that there are a lot of situations where being able to say with confidence that "this picture existed in exactly this form at exactly this date" is a super useful thing?
It doesn't prove when it was created, only that it existed. Previous poster /u/lolcatnip is talking about creation date
And that's all I'm saying that it does.
As I said, it's not perfection for every possible application. But it is still highly useful in many applications.
