If I take a picture with my beloved camera, the RAW file can be put into a blockchain, and thus it will have a unique hash.
If that unique hash is ever spotted anywhere we know it's a copy of my photo.
But if someone wants to steal my photo, they could just change a tiny bit of information in the RAW file, and it would result in a new unique hash.
So how can cryptography or the blockchain be used to protect digital assets?
