Reply to comment by Mrkvitko in Protecting ourselves against Deepfakes by Soft-Flamingo6003

Sure, there will be a need to trust the source, but you can still have some level of proof. Imagine that some politician says something horrible on camera. Then he decides to claim it's a deepfake. Using a blockchain you could prove that the video existed at a given date and had been claimed true by MSNBC, for example.

It's not great but I think it's the best we can do in the near future.

Which will give you nothing. It won't prove the video is a deepfake or not. Not to mention you're unlikely to do the verification by yourselves (generally, each time video is uploaded somewhere it is recompressed which changes its checksum). So you're relying on some "trustworthy institution" anyways.

In that case, you can drop the blockchain and just check what the institution says.
