If ordinary users can be display providers and make money, then Im sure that fraud may occur. You have specified minimum display requirements, but will you run a performance check to make sure the device is suitable?
To mitigate variation in local display units and ensure a minimum acceptable quality threshold for each and every display on the network, the HYGH player client runs a self-test at launch and relays key information on hardware, network connectivity, software updates and time zones back to the network.
And what should the provider do when an unexpected power outage? Does he get to lose his money just because of network problems?
