An example is Microsoft, which applied for a patent for a cryptocurrency system using body activity data As part of the cryptocurrency mining process, the cryptocurrency system assigns a task to your device, instructing you to complete a human body activity.

A sensor on the user's device registers body activity and then the cryptocurrency system rewards the user. The sensed body activity is associated with the receiving task and transmits the generated body activity data to a system or network, which verifies the body activity data to provide cryptocurrency.
