What is a cryptocurrency system using body activity data?
Could you elaborate on the concept of a cryptocurrency system that utilizes body activity data? Specifically, I'm interested in understanding how such a system might work. Would it involve collecting biometric data, such as heart rate or steps taken, and using that as a means to generate or transact cryptocurrencies? How secure is this method, considering the privacy and sensitivity of body activity information? And are there any current examples or implementations of this type of system in the market today? Your insights would be greatly appreciated.
