Deepfakes are a growing issue, and people want to know how to fight it.
One suggestion is to use blockchain.
Now, there is nothing wrong with this suggestion, except that it won't solve the problem. Existing graphic and video formats will not require (and sometimes not even accommodate) such blockchain verification, and it would take a very long time to create new formats that do and get everyone to agree to use them. In the meantime, a lot of bad people could create a lot of troublesome deepfakes. (Like these.)
Blockchain has become a magic term. Like "cloud" and "IPS" a lot of people don't really know what's involved, but assume it will solve all their problems. It won't.
(I still want to get the T-shirt that says, "No, blockchain is not the answer.")
