Patents: Cryptocurrency System Using Body Activity Data (Microsoft 2020/060606)
Heaven for some ... Hell for others
SUMMARY  Some exemplary embodiments of the present disclosure may use human body activity associated with a task provided to a user as a solution to“mining” challenges in cryptocurrency systems. For example, a brain wave or body heat emitted from the user when the user performs the task provided by an information or service provider, such as viewing advertisement or using certain internet services, can be used in the mining process. Instead of massive computation work required by some conventional cryptocurrency systems, data generated based on the body activity of the user can be a proof-of-work, and therefore, a user can solve the computationally difficult problem unconsciously. Accordingly, certain exemplary embodiments of the present disclosure may reduce computational energy for the mining process as well as make the mining process faster.
