B̳i̳l̳l̳ ̳G̳a̳t̳e̳s̳'̳ ̳M̳i̳c̳r̳o̳s̳o̳f̳t̳ filed the patent on March 20, 2020 to develop a cryptocurrency (called "666") that is distributed to people based on their bodily activity.
The idea behind it is to create a cryptocurrency that is connected to people's physical bodies. This system will be very different from the proof of work used for example by Bitcoin. On page 4 of the technical presentation of the project it is explained substantially how this digital currency would work.

"A brain wave or body heat emitted by a user when he performs the task assigned by a server provider, such as watching advertisements or using some Internet services, can be used in the cryptocurrency mining process. Rather than the massive computational work required by some conventional cryptocurrency systems, the data generated based on body activity can become proof of the work done, and therefore, a user can unconsciously solve the difficult computational calculation problem"

So when people carry out any daily activity (work, shopping, sports, etc) they would automatically receive this cryptocurrency.
The centralized system that creates this crypto detects people's bodily activities and distributes money based on the person's tasks.
In the technical explanation of how the operating system would work, there is even attached a sort of explanatory scheme.
People are connected to the central unit called the "cryptocurrency system" which produces digital currency and distributes it through a communication network.
But how does the system in practice give this coin to connected users?

"A sensor communicatively linked or inserted into the user's device can detect the person's body activity. A cryptocurrency system connected to a person's device (mobile phones, computers or laptops) can check if the body activity meets the conditions required by the system and assign the cryptocurrency to the person whose body activity has been verified"

In other words, the system that creates the cryptocurrency decides whether to pay a person a certain amount of digital currency based on his / her body activity.
If the system, for any reason, believes that someone is not performing the assigned task correctly, that person will not receive anything.
For example, if someone does not watch enough TV advertising, they will run out of money.

A subcutaneous microchip could be the ideal tool to connect a person to this system that produces global currency.
But not only: also smartwatch type devices.
A curious aspect concerning the project lies in its patent number: WO2020060606.
