I like the concept as long as it does not involve mining which would be pointless.
Running a node to maintain the blockchain I think would be very beneficial for decentralisation.
Think about it a lot more people have smartphones than PCs, dedicated servers, etc.
Currently too many challenges to make it happen and feasible but I could see this develop in the future.

A central focus of this blockchain is scanning through your smartphone camera.
Wouldn't mining be another point of success for blockchain? Validating blockchain transactions using mobile nodes is really an awesome idea. Although we are mostly accustomed to POW and POS consensus, it wouldn't remove the idea of mobile nodes giving way to newer consensus mechanisms. One that is ight and is almost ignore-able.
