China's digital currency characteristics:
China digital currency is the proct of the combination of traditional currency and the Internet, and is the Internet plus of financial and monetary domain. p>
-
China's digital currency will be the only digital currency issued by the state in the world so far, with national credit and currency anchor that bitcoin and other digital currencies do not have
-

-
China's digital currency relies on a secure and stable Internet. The promotion and application of quantum communication technology is of great significance to the security of China's digital currency

digital currency is an encrypted algorithm, just like a cash note with a unique number, which can not be tampered with< br />
what is China's digital currency:
if you look up physics books, it will say that the friction is only related to the material and roughness
but in fact, the friction force is not only determined by the above two conditions, but also by temperature, humidity, speed and other factors
the most typical example is a racing car. Only when the tire reaches a certain temperature can it grip the ground reliably, otherwise it is easy to slip and lose control.
the direction of static friction is opposite to the trend of relative motion, but the relative velocity is zero, and the velocity can be in other directions. For example: when the block moves in a circular motion with the horizontal turntable, the static friction force is the centripetal force of its circular motion, which points to the center of the track and is perpendicular to the direction of speed.
