Just like other mining rigs and antminers, our device faces a certain level of difficulty. The higher the wattage on our network the higher the difficulty. Essentially, our device operates on an equation that incorporates all the 'Watt' currently present on the network, along with your current 'Watt' calculation that you contribute. We calculate the total active 'Watt' generated by all the Current SolarX Miners and distribute them among the miners based on the amount of Watts they utilize.
