There are a lot of these copyright crypto coin projects out there at the moment, here's a few questions I have: 1. How can a block chain technically prevent people from just registering 1000's of photos found on the internet? Even if there is a cost. 2. Who can validate who took what photo? 3. How do they link the photo to the registry? Any small change in a single pixel, would alter the hash of the photo and pass through their web crawlers. Maybe they mint you a Kodak Coin every time you take a photo, which you can spend on copyrighting it...
