I think this technology will become mandatory for security cameras and the like. There will come a day when video and pictures lacking this blockchain extra won't be admissible in court. But blockchain has scalability issues and I doubt there will be a day in the near future when every cellphone camera is bothering with this instead of old fashioned jpg and other simple data types. ...also see how slow America was to adopt ICD-10 and the credit card chip readers...This is where the technology underlying Bitcoin - the blockchain - can be of service. Blocks in the blockchain are timestamped with a difficult to fake cryptographic checksum, and the blocks are linked in sequence, so that if one is altered, it is immediately evident it has been. Bitcoin happens to use this to secure financial transactions, but it works for any kind of data whatsoever, such as a video stream.
There can also be problems where someone puts the deep fake in front of the secured camera to trick it. I'm not just talking about putting a literal monitor in front of a physical camera, there may be many obvious and non obvious ways to hack it.
Even if the secured cameras are all untouchable, there may be plenty of those old style images shot by amateurs on a cell phone that some people want to believe, and others don't even when they should.
