practical significance
the digitalization of central bank's currency helps to optimize the central bank's monetary payment function, improve the central bank's monetary status and the effectiveness of monetary policy. The central bank's digital currency can become an interest bearing asset to meet the holder's reserve demand for safe assets, and can also become the lower limit of bank deposit interest rate
can also become a new monetary policy tool. At the same time, the central bank can affect the bank's deposit and loan interest rate by adjusting the central bank's digital currency interest rate, and help break the zero interest rate lower limit
operation system
fan Yifei, vice governor of the people's Bank of China, said in the article that the digital currency of the people's Bank of China should adopt a two-tier operation system. This model does not change the relationship between creditor's rights and debt of currency in circulation, does not change the existing money supply system and al account structure, does not constitute a competition for commercial banks' deposit currency, and does not increase commercial banks' dependence on the interbank lending market
will not affect the lending ability of commercial banks, and will not lead to the phenomenon of "financial disintermediation". At the same time, because it does not affect the existing monetary policy transmission mechanism, it will not strengthen the pro cyclical effect under the pressure environment, and it can improve the convenience and security of payment, and it also has the credit advantage of central bank endorsement
The digital currency of the central bank is DCEP
the name of the digital currency developed by the central bank is DCEP (digital currency electronic payment). DC is digital currency. EP is electronic payment. Payment transmits digital things through a certain way, not paper currency. Therefore, electronic payment itself has the attribute of digital currency
The characteristics of digital currency are: low transaction cost; Fast trading speed; Highly anonymous

Application of digital currency
I. fast, economic and safe payment and settlement
cross border payment helps RMB internationalization. In 2015, the settlement volume of cross-border payment involving current account is about 8 trillion yuan. To accelerate the internationalization of RMB, cross-border payment and settlement procts and solutions with low cost, high efficiency and low risk are needed
At present, there are still a lot of repetitive human work in the bank's electronic loan process and processing process, and as the basic support of loan issuance, many of the collateral has the situation of false pricing or multiple or even no collateral. We can consider using digital currency to price and track bank collateral:3. Bill finance and supply chain finance
in recent years, various bill market businesses based on commercial bills have grown rapidly, and bill financing procts have become a hot area of Internet financing. However, about 70% of the current bill businesses in China are still paper transactions, Supply chain finance is also highly dependent on labor costs

Digital RMB, issued by the people's Bank of China, is a controllable anonymous payment tool with value characteristics and legal compensation, which is operated by designated operating institutions and exchanged with the public. It is based on the generalized account system, supports the loose coupling function of bank accounts, and is equivalent to banknotes and coins

digital currency has the main characteristics of network packet. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes
based on the characteristics of digital money, the direct benefit of digital money to the central bank is not only to save the cost of paper money issuance, circulation and settlement, but also to enhance the central bank's ability to control funds.
f=N μ N is the positive pressure, that is, the pressure acting on the contact surface, μ It is the dynamic friction coefficient, which refers to the influence factors of the roughness of the contact surface on the friction. Or use the balance f = f; It's only used when it's stationary or moving in a straight line at a constant speed, but it's the most used in junior high school
the so-called friction is the force that hinders the relative motion of the object, and the direction of friction is opposite to the motion direction or relative motion direction of the object. The conditions of friction are as follows:
(1) two objects must contact each other
(2) there was extrusion between two objects(3) there is a tendency of motion or relative motion between two objects
If an object is stationary on a horizontal plane, it will not be affected by friction if it is not pushed or pulled. If thrust or pull is received, it belongs to the category of static friction. The size of friction is equal to that of pull or thrust, and has nothing to do with the gravity or pressure of the object. Only the maximum static friction is related to the pressure or gravity on the object
if the object is not pushed by 10N force, the object will be subjected to static friction, which is equal to the thrust. Just push with 15N force, and the friction force on the object is the maximum static friction force. If the thrust force is increased later, the friction force will not change. Theoretically, the sliding friction of objects is less than the maximum static friction, but it is generally considered that they are equal
The friction force is f = 15-10 = 5N
extended data:
methods to increase beneficial friction
(1) increase the roughness of contact surface
(2) increase the pressure (3) change rolling friction into sliding friction (1) replace sliding friction with rolling friction(2) make the contact surface separate [form a layer of air cushion or magnetic suspension on the contact surface of the object]
(3) decrease the pressure (4) rece the roughness of the contact surface In engineering technology, people often rece friction by applying lubricating oil. The science of this problem is called tribology, which is a branch of mechanical manufacturingIf two objects, which are in contact with each other and squeeze each other, but relatively still, only have a relative sliding trend under the action of external force, but do not have relative sliding, then the force between their contact surfaces hindering relative sliding is called "static friction". When the static friction increases to the maximum, the object will move
size: the static friction varies according to the external force, but there is a maximum value, which is called the maximum static friction. The maximum static friction is slightly greater than the sliding friction
direction: tangent to the contact surface, opposite to the direction of relative motion trend
On the basis of a large number of experiments, G. amunton and C. - A. de Coulomb proposed the following law of friction in 1699 and 1781:① the friction between two objects in contact does not exceed a certain maximum value, which has nothing to do with the size of the contact area
(2) the maximum value of friction is proportional to the normal pressure n between two objects (3) the direction of friction is opposite to the sliding direction of the object, and its magnitude is directly proportional to the normal pressure n between the two objectsthe above conclusion is only a rough empirical rule, but because it was found in the early days of mechanical science, it was called the law of friction, also known as Coulomb's law
the significance of DCEP is that it is not the digitization of the existing currency, but the replacement of M0. It greatly reces the dependence of trading links on accounts and is concive to the circulation and internationalization of RMB. At the same time, DCEP can realize the real-time collection of money creation, bookkeeping, flow and other data, which provides a useful reference for the money supply, the formulation and implementation of monetary policy
What are the characteristics of DCEP
1. The value of DCEP is only linked to RMB
unlike Libra, DCEP is directly linked to RMB
2. DCEP has unlimited legal compensation
the so-called unlimited legal compensation means that no matter how much money is paid, the other party cannot refuse to accept it
3. DCEP can realize value transfer without an account
DCEP does not need to be connected to the Internet. As long as DCEP digital wallet is installed on the mobile phone, the value can be transferred by touching each other
4. High security of assets
DCEP is directly issued by the central bank, and there is no problem of commercial banks and enterprises going bankrupt< To sum up:
DCEP will adopt a two-tier operation system, which is guaranteed by the central bank's credit and has unlimited legal compensation. The introction of central bank's digital currency is related to the internationalization of currency. Whether RMB can be internationalized through blockchain is an important opportunity. It is also a brand-new attempt of the central bank to digital currency under the new situation and a proct of the central bank's compliance with the tide of the times.
