A communication network may include a first computer and a second computer configured for communication with each other. The second computer may include a project manager module configured to receive computing projects from the first computer and manage the execution of work tasks for the computing projects. The project manager may throttle performance if needed to prevent negative impact on the performance of other applications also being executed on the second computer, such as a video game. Rewards for performing the work tasks may be automatically converted from a first cryptocurrency to a second currency such as a video game currency.
