Is central people's digital currency cash

1.

China does not issue digital currency, and all the existing digital currencies are illegal

the central bank pointed out that no legal digital currency has been issued, and no institutions and enterprises have been authorized to issue legal digital currency. At present, the so-called "digital currency" in the market is not legal digital currency

virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency

"the legal currency of our country is RMB." In the risk warning, the monetary Bureau of the people's Bank of China once again stressed that RMB is uniformly printed and issued by the people's Bank of China

extended information:

with the soaring price of virtual currency represented by bitcoin, digital currency and the blockchain technology behind it have attracted great attention of the global financial community. In fact, legal digital currency has not yet been issued in China. Recently, the official website of the monetary Bureau of the people's Bank of China (PBOC) released the risk warning on issuing or promoting digital currency in the name of the people's Bank of China

in 2013, the central bank, together with five ministries and commissions, issued the notice on prevention of bitcoin risks, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, which do not exist in the form of currency and legal currency

At the same time, digital money is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized

such as Internet banking, WeChat, Alipay and other payment electronic popularization graally, physical cash accounts for only a very small part of all circulating currencies. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotes

currently, digital currency in the market involves multi-level marketing

digital currency is a new technology that can improve the efficiency of transaction, but it is targeted by lawless elements to carry out pyramid selling and fraud in its name

the official website of the monetary Bureau of the people's Bank of China issued the risk warning on issuing or promoting digital currency in the name of the people's Bank of China. The central bank pointed out that recently, indivial enterprises falsely used the name of our bank to label relevant digital procts as "authorized issuance by the people's Bank of China", or falsely claimed that the digital currency promotion team of the central bank issued, in an attempt to deceive the public and take the opportunity to make huge profits

in the risk warning, the central bank stressed that the bank has not issued legal digital currency, nor authorized any institutions and enterprises to issue legal digital currency, and there is no promotion team. At present, the so-called "digital currency" in the market is not legal digital currency

at the same time, the so-called "digital currency" launched by some institutions and enterprises and the so-called promotion of the central bank's issuance of digital currency may involve pyramid selling and fraud. The general public should raise their risk awareness, invest rationally and prudently, and prevent the interests from being damaged

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

3. In order to make it more convenient for us to use money now, and in other words, to facilitate the circulation of money.

4. In theory, the central bank issues digital currency to replace paper money. However, this process is very slow, because the development of various regions in China is seriously unbalanced, and the acceptance of digital currency is also different. The digital currency trial run by the central bank is only applied to the bill market
in the future, there may be many digital currencies in China, and each digital currency will have its own application. For example, Puyin is a very interesting digital currency, which corresponds to the assets related to tea.

5. On the issue of issuing their own digital currency, central banks are always less thunderous. Central banks around the world are considering issuing their own digital currencies to compete with cryptocurrencies such as bitcoin, but they have been unable to do so for a long time

the media's attention to the central bank's digital currency has increased significantly, especially after Zuckerberg testified in Congress on the Libra issue and Christina Lagarde acknowledged the "clear demand" for stable currency at her first media reception as president of the European Central Bank, which seems to have changed the public's view on this matter, Let many people in cryptocurrency community think that cbdcs is in sight<

according to the latest survey report released by the bank for International Settlements, central banks in the past seven years have been investigating this technology and assessing its impact. Of the 63 central banks surveyed, 55 said they were unlikely to issue cbdcs in the next three years, and only one reported that they were "highly likely to issue large-scale cbdcs in the next three to six years."

although the proportion of central banks studying cbdcs is very high, the crux of the problem is that it is mainly theoretical and investigative work. Only five central banks have concted more in-depth research and real project development or experimentation - but that still does not mean that they will necessarily issue cbdcs

through close observation, it is more and more obvious that both Libra recently released by Facebook and the new stable currency assets have had a significant impact on the central bank. Today's situation took hundreds of years to form, but it changed in a few months; Competition, the most terrifying and unfamiliar concept that has never been thought of before and penetrated into the elite society of central banks, is now knocking at the door

it can be said that the solution to the current situation is still unclear. Some people who are familiar with these things even say that they are bluffing. However, in Lagarde's own words, the slow and wait-and-see regulatory approach can no longer meet the needs

1. What is central bank digital currency<

what is the difference between central bank digital currency CBDC and other digital currencies

CBDC is a new form of currency, which is directly issued by the central bank in digital form as legal tender. The current form of legal currency is cash, reserve deposit or balance settlement< There are two main differences between CBDC and other digital currencies (including cryptocurrency and other forms of central bank currency):

1. CBDC has nothing to do with cryptoassets. They're not decentralized, they don't have to be blockchain based, and they're certainly not anonymous, they're not unlicensed, they're not censored< 2. Contrary to the current digital cash, the operation structure of CBDC will be different from other forms of central bank currency. CBDC has more powerful functions. They are programmable, can generate interest, can be cleared in near real time, and have cheaper handling charges and wider openness

when designing CBDC, the speed of central banks is different. Different central banks adopt their own approach. However, in general, there are three problems being explored: whether CBDC should be based on token or account number, whether CBDC should be batch (only open to banks) or retail (open to the public), and whether it should be based on DLT

when CBDC is to be implemented, things will become complicated, and there are many thorny problems to be considered

for example, once CBDC is launched, does it need to cancel cash? Should CBDC carry interest? Should they have face value like cash? Or linked to the total price index? What impact will this have on commercial banks? What about anonymity and privacy? All these questions need to be answered<

2. Motivation for issuing CBDC

in the 2017 staff discussion paper, the Bank of Canada gave six reasons for issuing CBDC in an article entitled "central bank digital currency: motivation and impact":

1. Ensure that the central bank provides sufficient cash to the public, and maintain the seigniorage revenue of the central bank

2, Support non-traditional monetary policy

3. Rece overall risk and improve financial stability

4. Improve payment competitiveness

5. Promote financial inclusiveness

6. Curb criminal activities

looking back at the bank for International Settlements survey we analyzed earlier, payment security and domestic efficiency are selected as the most important motives of the central bank. According to a large number of papers published by the central bank and other large financial institutions, for developed countries, the transformation into a cashless society is the main driving factor, while for developing countries, financial inclusiveness, cost rection and operational efficiency are the main motivation

throughout the rest of the reports and the literature that can be found, the fierce competition brought about by bitcoin and other innovations in the cryptocurrency instry, as well as the clear need for "one step ahead", of course, are not listed as the reasons for issuing CBDC< The advantages and potential risks of CBDC are very low.

if the central bank starts to launch CBDC and succeeds in the end, there are many potential benefits

from a technical point of view, CBDC is much better than the current form of legal currency. They can be tracked better, collect taxes more conveniently, transmit monetary policy better, have better financial inclusiveness, and rece the cost of procing physical currency

the most obvious advantage is that payment is cheaper and faster, whether it is domestic payment or cross-border payment

in addition to the design and implementation problems, a key problem of issuing CBDC is that CBDC may increase the risk of bank operation. However, this only happens when banks promise that their deposits can be converted into CBDC on demand, which is not necessarily the case, according to the Bank of England document

4. Facts on the ground

how far is it from us to see a real CBDC appear in the market? It's hard to estimate, but at present, we can sum up the current situation in one sentence: all talk but no practice

if we put aside the failed digital currencies of Ecuador, Tunisia and Venezuela, we can only do theoretical research, a small amount of experiments, and issue some feasible CBDC issuance announcements supported by the state in the future

the most famous CBDC projects in progress are: e-peso in Uruguay (the project was successfully tested in 2018), DCEP in China, "project Inthanon" in Thailand, e-krona in Sweden (still in the research stage)...

5. The revolution has not yet been successful, and comrades still need to work hard

considering the factors mentioned above, Most of the headlines about CBDC's upcoming release are groundless. All projects scheled to be released this year have been delayed

in fact, there is still a long way to go for the birth of CBDC, and to convince the public, we need more than a statement. Given the current situation, it seems that CBDC and other cryptocurrencies may not affect each other - at least for now.

[main answer]

at present, China does not support the circulation of digital currency, so there is no legal digital currency

[development materials]

digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English and the alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency

digital gold currency is a kind of physical currency, and its deposit is measured in gold rather than legal currency. Therefore, the purchasing power fluctuation of digital gold currency is related to the gold price. If the price of gold goes up, it becomes more valuable. If the price of gold goes down, it loses value. Since there is no specific financial regulation to regulate digital gold money suppliers, they operate in a self regulatory manner. Digital gold money suppliers are not banks, so banking regulations are not applicable. However, the global digital currency Association, founded in 2002, is a non-profit association of online currency operators, convertors, merchants and users. This association supervises the users' reports and ratings the reputation of the convertor. The rating operation is confirmed by the users' reports

7. 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.

8. There is no need to exchange it. It is the digital form of RMB. It's legal tender. It's compulsory circulation.

To calculate the helical gear parameters, you need to know the basic parameters:

normal molus M_ n. Number of teeth Z, normal pressure angle α_ n. Helix angle β

generally, the crown height coefficient h * is 1, and the root height coefficient C * is 0.25. If there is displacement, it is necessary to calculate the displacement: x

the following is the basic parameter

end face molus: M_ t=m_ n/cos β

Calculation formula of pressure angle at the end face: Tan α_ t)=tan ( α_ t)/cos( β)

diameter of dividing circle: D = m_ n × z/cos( β)

addenm circle diameter: no displacement: Da = D + 2 × m_ n × H * with displacement: Da = D + 2 × m_ n × H * + x)

root circle diameter: no displacement: DF = D-2 × m_ n ×( H * + C *) with displacement: DF = D-2 × m_ n ×( H * + C * - x)

diameter of base circle: DB = D × cos α_ t)

in addition, there are more important dimensions, such as normal pitch, end pitch, etc., which can be obtained by referring to relevant manuals

Extended data:

judgment of helix rotation direction: first, we make the gear axis vertical, if the right height of helix is right rotation; On the contrary, the height on the left side of the helix is left-handed

end face and normal surface parameters:

end face: the plane perpendicular to the gear axis, and the parameters on the end face are generally added with subscript t

normal plane: the plane perpendicular to the helix, and the parameters on the normal plane are generally subscript n

(1) pitch and molus: = t= π

(2) pressure angle: generally, the parameters in normal plane are standard parameters

The correct meshing condition: the helix angle must be equal in size and opposite in direction. The normal molus m is equal to the normal pressure angle

B. geometric dimension calculation: in calculation, the calculation formula of spur gear can be directly applied to the end face of helical gear because a pair of helical gear transmission is equivalent to a pair of spur gear transmission on the end plane

there are many kinds of gear transmission, among which the efficiency of helical gear is very high, for example, the efficiency of spur gear transmission is lower than that of helical gear transmission

Like spur gear mechanism, helical gear can be used to improve the load capacity of transmission by recing the center distance a, which can be used for high-speed operation. Helical gear recer is a new type of recer. The helical gear recer is small in volume, light in weight and good in economy

Advantages:

(1) good meshing performance: the meshing process between helical cylindrical gears is an excessive process, and the force on the teeth is graally from small to large, and then from large to small; Helical gear is suitable for high speed and heavy load

(2) large coincidence degree: the increase of coincidence degree can improve the bearing capacity of gear. So the life of the gear is prolonged. The coincidence degree mainly depends on the meshing time, while the long meshing time and large contact area of helical gear rece the stress. The transmission is stable and the economy is increased

(3) compact structure: the less the minimum number of teeth, the more compact the structure
