Bank currency figures

1. The virtual currency we use on the Internet, such as q-coin or other game currency, is strictly virtual goods or intermediate goods. It is not money and does not have the purchasing power of legal tender. bitcoin, which is more talked about in the market, is also different. It is a decentralized virtual currency realized by using blockchain technology, which is easy to facilitate money laundering. Therefore, the application of blockchain technology should not be copied. If the central bank issues digital currency, it should be a kind of centralized currency. The legal currency issued by the central bank, encrypted and supported by national credit, should meet the regulatory requirements
a few days ago, Indian Prime Minister modi announced the issuance of a new currency aimed at combating tax evasion and money laundering. In fact, if the central bank issues digital currency with perfect technology and mature mechanism, it will have better effect. Because the digital currency, in addition to anti-counterfeiting, with the help of blockchain technology, makes the capital data traceable and highly transparent. These features can also be used for macro data statistics and monitoring, which has positive significance for big data risk control
as for what bank digital currency is, the central bank requested at the meeting on January 20 this year that the research team of the people's Bank of China should actively absorb the important achievements and practical experience of digital currency research at home and abroad, continue to promote on the basis of preliminary work, establish a more effective organizational guarantee mechanism, and further clarify the strategic objectives of the central bank in issuing digital currency, Do a good job in tackling key technologies, study the multi scenario application of digital currency, and strive to launch the digital currency issued by the central bank as soon as possible.

2. In the era of physical money, money itself has intrinsic value, so it can perform these functions of money. However, modern credit money or paper money itself has no value, why can it perform the function of money? This is because the credit currency is supported by the national credit, which has the nature of legal compensation and compulsion. National credit is not only the value basis for the standard currency to perform its monetary function, but also the basis for the state to monopolize the right to issue currency< At the same time, monetary policy is an important means for modern countries to adjust their economy. The change of money supply has a wide influence on economy. Nowadays, central banks all over the world make full use of monetary policy to regulate economic operation
monetary policy, like tax, police, court and other state machines, is the foundation of modern state operation and an important part of state machine. As long as there is no fundamental change in the social organization form of the state, the monetary system based on the national credit will always exist, and bitcoin and other virtual currencies will not become the standard currency of a country. Bitcoin is actually just the use of technology, which is at most an asset, not a real currency< Of course, credit money is prone to inflation. In a sense, people's concern about bitcoin reflects people's worry about inflation under the condition of credit currency. Therefore, central banks should strengthen liquidity management, reasonably regulate money supply and keep prices basically stable.

3. Bank of China has not launched or plans to launch any digital currency, let alone specific events. In China, the major commercial banks have drawn a clear line with digital currency for a long time. Although the attitude towards digital currency is not so cold now, the law is still not prohibited. However, the central bank held a digital currency seminar earlier this year and planned to launch its own digital currency, which is different from cryptocurrencies such as bitcoin, Ruitai and Laite.

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 manufacturing

If 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 objects

the 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

Digital RMB is legal tender with unlimited legal compensation. Unlike the three party payment tools such as WeChat Alipay, the use of digital Renminbi can be completed without binding the bank account. p>

in transaction payment, no unit or indivial can refuse to accept digital RMB. To make payment more convenient while ensuring safety is the first consideration of digital RMB. The central bank's digital currency DC / EP adopts a two-tier operation system. The people's Bank of China issues digital currency directly to the public

In the two-tier operation system, the people's Bank of China first exchanges digital currency to banks, and then these institutions exchange digital currency to the public. So it seems that your salary should be paid to the bank account first, and then converted into digital RMB

extended information:

the introction of digital RMB is as follows:

it is mainly used in the high-frequency business scenario of small retail. It adopts a two-tier operation system. The central bank first exchanges the digital currency to banks or other operating institutions, and then these institutions exchange it to consumers. It is understood that digital RMB is not a virtual currency, nor an online payment or e-wallet, but a legal digital currency issued by the central bank based on national credit

for financial innovation, it can not be completely realized. In this case, the relevant representatives of the central bank put forward the relevant contents of digital RMB and pointed out that the era of digital RMB is coming

6. We use virtual currency such as currency or other game currency on the Internet. Strictly speaking, it is a virtual commodity or intermediate commodity. It is not money and has no purchasing power of legal currency. Bitcoin, which is more talked about in the market, is also different. It is a decentralized virtual currency realized by using blockchain technology, which is easy to facilitate money laundering. Therefore, the application of blockchain technology should not be copied. If the central bank issues digital currency, it should be a kind of centralized currency. The legal currency issued by the central bank, encrypted and supported by national credit, should meet the regulatory requirements
a few days ago, modi of India announced the issuance of a new type of currency to combat tax evasion and money laundering. In fact, if the central bank issues digital currency with perfect technology and mature mechanism, it will have better effect.

In fact, with the development of science and technology, more and more people can enjoy the dividend of the development of science and technology, and also can let themselves have a better convenience. Most of the time, we can make better use of science and technology, and also can make science and technology better function, can make us more dependent on science and technology, more convenient for our daily life

with the development of Internet technology, more and more people may use some new payment methods, such as digital RMB, and our country is constantly developing digital RMB, and can also have a better application. Six state-owned banks begin to promote digital RMB currency wallet. Is the era of digital RMB coming? I think it's all coming. There are three reasons for this: first, digital RMB has been widely promoted

in my opinion, I think the era of digital RMB is coming, because I think digital RMB has been widely promoted, which can make many people accept the digital RMB and use it. Therefore, it may come in the near future{ RRRRR}

that's my opinion. Do you have any ideas

8. It's source value

9. Money actually represents a kind of purchasing power. For example, one dollar = the purchasing power of a McDonald's hamburger

when a country increases its currency circulation or changes its currency circulation data, the purchasing power of money will change very quickly. If the U.S. adds a zero to the total amount of money, it will soon become $10 = a hamburger. In this way, the savings of the local people will become one tenth of the original, and then the country will be in a mess

in addition, when you go to buy things from foreigners, you actually trade your domestic procts for foreign currencies, and then you buy them with foreign currencies, that is, your own foreign exchange reserves. If you increase the total amount of domestic currency, but you do not increase the domestic goods on hand, you will only have as much foreign currency as before, and the things you buy will not increase at all.
