Unity plugin developer Icoplay has come up with a new way for developers to monetize free apps on the App Store while avoiding in-app purchases, through the use of bitcoin mining. Bitcoin is a digital currency first developed in 2008 that has soared in value in recent years. While bitcoin value fluctuates wildly, a single bitcoin today is worth approximately $200, which makes Bitcoin mining a potentially lucrative endeavor. Because new bitcoins are generated via complex math problems, Bitcoin mining requires an incredible amount of processing power. Icoplay is aiming to use mining software hidden within apps and games to take advantage of the latent processing power of mobile devices, rewarding the developer with bitcoin. Like distributed computing projects such as SETI@home, Bitcoin mining can be done in small chunks over hundreds or thousands of devices.
