BitWrk is creating a marketplace where participants can buy or sell computing power like stocks in a stock exchange, using Bitcoin as currency. The client software can be integrated with existing, compute-intensive applications (e.g. rendering software), creating a big boost by harnessing the combined computing power of the BitWrk network. Sellers earn money by putting their hardware to work, offering an alternative to Bitcoin mining.
