It has value characteristics and legal compensation, and supports controllable anonymity. There are two key points in the concept of digital RMB.

related introction:

e-money can transfer the balance in the bank through some electronic ways, so that transactions can be carried out. The anti-counterfeiting of traditional currency depends on the specific essence, while the anti-counterfeiting of electronic currency can only be realized by electronic technology, communication technology and encryption or authentication system

extended data

in the field of modern economy, only a small part of the currency field is displayed in the form of real currency, that is, most transactions use checks or electronic currency

As far as the intrinsic commodity value of money is concerned, it is not a choice with or without two breaks, but a process of graal quantitative change. The commodity value of e-money is almost zero, that of paper money is close to zero, that of coins and copper plates is slightly higher, and that of precious metal currencies such as gold and silver is higher

this process of quantitative change reveals the unity of the essence of different forms of money, that is, as the proct of contract, the exchange value of money is agreed by contract. When the market is stable and the trust is high, people accept paper money and other nominal money. When the market is unstable and the trust is low, people tend to accept metal money

6. You're talking about the formula for calculating the mass of iron plate
in physics, mass m = density of object ρ× The volume of the object is V, so it is necessary to measure the length, width and thickness (CM) of the iron plate first, and multiply the three to get the volume in cubic centimeter. And then multiply it by the density of iron, 7.86 grams per cubic centimeter
for example, the size of iron plate is 500 * 100 * 10cm
the mass m of iron plate is: 500 * 100 * 10 * 7.86 = 3930000 g = 3930 kg = 3.93 t
