Virtual currency of central banks

1. After the people's Bank of China announced the launch of digital currency as soon as possible in January this year, Zhou Xiaochuan, governor of the people's Bank of China, recently gave a detailed description of the development of digital currency in an interview with Caixin weekly
Zhou Xiaochuan pointed out that as legal tender, digital currency must be issued by the central bank. The issue, circulation and transaction of digital currency should follow the idea of integration of traditional currency and digital currency, and implement the same principle of management. That is to say, q-coin and the like are definitely not good
as for whether to use blockchain technology to create digital currency. Zhou Xiaochuan said that the blockchain technology is an optional technology, but so far, the blockchain still occupies too many resources. Whether it is computing resources or storage resources, it can't cope with the current transaction scale, and whether it can be solved in the future depends on it. Zhou Xiaochuan said that in addition to blockchain technology, the digital currency research team of the people's Bank of China has also concted in-depth research on other related technologies involved in digital currency, such as mobile payment, trusted and controllable cloud computing, cryptographic algorithm, security chip, etc
it is certain that the digital currency issued by the central bank can never be the same as bitcoin, Ruitai, Qianjin card and other digital currencies. The digital currency issued by the central bank is just the digital currency.

2. What are the current views of central banks on digital currency? Money is money. It's inflated now

3.

according to foreign media reports, with the growing popularity of bitcoin, central bank governors around the world have also expressed their views on this digital currency

Federal Reserve Bank of the United States

in December last year, at the monetary policy meeting of the Federal Reserve Bank of the United States, Janet Yellen, chairman of the Federal Reserve Board, was asked what she thought of bitcoin

According to Yellen, this kind of digital currency is a "highly speculative asset" and "cannot be legal tender". She added that it "plays a negligible role in the payment system" and that it "is not a stable store of value."

"the Federal Reserve Bank will not make any policy on bitcoin. Instead, we will only ensure that the banking institutions we supervise pay close attention to digital currency and properly manage their interaction with traders in the market. Moreover, we will monitor whether these banking institutions have fulfilled their responsibilities to combat money laundering and ensure the safety of banks. " Yellen said

at the end of November last year, Jerome Powell, who will replace Yellen as chairman of the Federal Reserve in February this year, also expressed his views on cryptocurrency. Cryptocurrencies "don't matter now" because "they're not big enough," he said

According to Powell, the financial risk brought by digital currency to the financial market is minimal“ They're not big enough, they don't matter now. " He said

European Central Bank

in October last year, Mario Draghi, President of the European Central Bank, said that cryptocurrency was not "mature" enough for the central bank to regulate management

"for anything new, people are always full of expectations, but also feel very uncertain. Now, as far as bitcoin and other cryptocurrencies are concerned, we don't think they are mature enough for us to consider standardized management. " He said

Draghi pointed out that tools like bitcoin have both advantages and disadvantages, and we need to weigh them carefully

"a lesson of the great financial crisis is financial innovation. As far as bitcoin is concerned, it is a financial and technological innovation. We should pay close attention to its potential risks while paying attention to it. " He said

Bank of Canada

in December last year, Stephen poloz, President of the Bank of Canada, also spent some time discussing cryptocurrency. He claims that buying digital currency is a gamble, not an investment

"perhaps no one can say clearly what their real value is. One can at most say that buying digital currency is buying risk. This makes it closer to gambling than investment. " "For people who want to buy cryptocurrency, what I want to say is that you should read the collateral to make sure you know what you're investing in," boloz said

According to boloz, the demand for digital currency will increase in the future. He added that the Central Bank of Canada was studying whether to issue its own digital currency

"bank staff are studying the conditions under which the central bank is more suitable to issue its own digital currency for retail transactions." He said

Reserve Bank of Australia

in December last year, Reserve Bank of Australia President Philip Lowe talked about bitcoin in a speech. He pointed out that this kind of digital currency will not be used in daily payment activities, and it can not be accepted so soon

According to Lowe, the reason is that the price of bitcoin is extremely unstable, the number of payments that can be processed at the same time is limited, the transaction and electricity costs are too high, and the management is too difficult

moreover, when bitcoin is only used as a payment tool, it "is more likely to attract those who want to trade in black or illegal economic activities."

Bank of Japan

at the end of 2017, Haruhiko Kuroda, President of Bank of Japan, said the price fluctuation of bitcoin was "extremely abnormal"

when asked if there will be a bubble in bitcoin, he replied, "I may not be qualified to evaluate it, but if you look at its trend, you will see that its price fluctuation is very abnormal. If you want to ask whether bitcoin has the same function as money, that is, as a payment or settlement tool, then my answer is No

investment should be cautious and private letter from mining machinery is needed

According to the published data and conclusions, China will be ahead of foreign countries in terms of science and technology theory, e-payment habit and mature payment system{ RRRRR}

finally, in China, the electronic payment system is relatively perfect, that is to say, if digital currency is implemented in the future, it can be easily implemented, and the related construction cost is relatively low. Moreover, whether it is digital currency or electronic payment, the difference between the two is not big, and digital currency can adapt to more diverse scenarios, and people can accept it more easily, It will not become unaccustomed because of the sudden change, which will also lay a good foundation for the development of digital currency in our country. However, such a system and payment habit are not possessed by other countries at all, and most countries are not used to electronic payment, so there is no digital currency base at all

5. Understanding of the concept of virtual currency
(1) virtual currency based on entity
since ancient times, all "money" made of paper is called paper currency, and all countries in the world are actually paper currency. In Marx's time, paper money was only a symbol of metal money. The actual gold content of paper money was equal to the nominal gold content. When the nominal gold content was greater than the actual gold content, the price index of metal money would increase because of too many paper money. When it exceeded a certain limit, inflation would occur. Marx called these over issued bank notes without gold as guarantee virtual currency. In Keynesian era, paper money was the symbol of GDP. He defined the issue of paper money caused by making up the fiscal deficit as deficit money, and believed that the issue of paper deficit money could promote the development of proction to a certain extent, but only cause half inflation. Zhang chunjia's research in "Introction to virtual currency" also proves that paper money without precious metal and GDP guarantee will cause price rise, and this kind of money is called virtual currency
(2) virtual currency based on virtual
virtual currency is a new type of currency emerging at a certain stage of network social and economic development to meet the security and convenience needs of users. It represents the development direction of future currency existence form. It comes from the Internet, and acts as a general equivalent in the network society completely or partially. Virtual currency is a real currency with the basic attributes of currency, but it is virtual and depends on the network virtual environment. Virtual currency is born without borders, which makes it more liquid than traditional currency in the world. Virtual world corresponds to the real world. Through the exchange relationship between virtual currency and traditional currency, under certain conditions, specific virtual currency can buy physical goods, and traditional currency can also buy specific virtual goods< Second, the characteristics of virtual currency
1. Value: users get utility value by consuming the procts and services provided by operators. Virtual currency has value by providing exchange to meet the utility of consumers. The quantity of virtual currency measures the value of general goods. The issue essence of virtual currency is credit issue, which is the creditor's right of the holder to the issuer. To a certain extent, the value of this kind of claim is the right of claim
2. Virtual environment dependence. The existence of virtual currency is based on the virtual economic environment provided by the issuers and the sustainable operation of the issuers themselves. Otherwise, virtual currency has no significance.
3. Short sighted currency. As the highest price in the process of commodity exchange, the form of currency value can be regarded as the real currency. Because of the limitation of circulation scope, virtual currency can not be used as the general equivalent of all commodities; But in a certain range, it has the function of monetary value scale and circulation means. Therefore, it can be considered that virtual currency is similar to the form of money value, and it is a primary form of money, which is similar to money< The issue and circulation of virtual money is limited, but it will enlarge the money supply through the money multiplier effect, and affect the difficulty and accuracy of macroeconomic regulation and control. The issuers of virtual money need to report their circulation and circulation to the central bank, and obey the unified management of the central bank at any time
5. Virtual currency, which is issued by non-financial entities outside the financial system, aims to obtain business opportunities and competitive advantages. It is a market behavior and will inevitably lead to competition among issuers. This kind of competition will proce unfair competition behavior or obtain competitive advantage through rent-seeking, which determines the need to regulate the market behavior of the market subject according to the laws and regulations
6. Virtuality: as a kind of approximate currency, virtual currency is virtual existence if it only exists in the virtual world and can purchase the virtual property in it; If it is linked with sovereign currency, it can exist in the real world and purchase real assets, then it is a virtual thing of sovereign currency. Virtual currency is actually a series of data files existing in the computer system. It has the meaning of virtual currency only after the issuers explain the system. Therefore, the existence form of virtual currency is virtual< In general, virtual currency can purchase the procts and services provided by the issuers, and it can also be exchanged with the issuers outside the scope of issuance at a certain rate to purchase the procts of the alliance. For procts outside the alliance, virtual currency has no value significance; Similarly, when virtual currency is only authorized to buy different procts in different sales cycles, the use of virtual currency has limited application in time and scope, unlike sovereign currency, which can be completely freely exchanged
8. Separability: virtual currency has no physical form and is a digital storage information. Unlike traditional paper currency, it needs to consider the balance relationship between the circulation of main currency and subsidiary currency and the proportion of various currency values. It can be split infinitely. For example, although the total number of dark coins is only 2300, each bitcoin can be split into eight directions of ten< Although virtual currency exists in the virtual world, the process of new technological revolution has closely linked the virtual world with reality, and the virtual world has become an important part of people's spiritual life. It can promote the development of real economy, for example, a large number of entertainment application projects provide people with rich spiritual wealth and real wealth, and more and more people invest in virtual currency, which represents a trend, and the more successful ones are bitcoin, Leyte coin and the new domestic King coin; On the contrary, money laundering, gambling and network theft in the virtual world will have a negative effect on the real economy.

China does not have the first legal virtual currency. At the end of 2013, the central bank and other five ministries and commissions issued the bitcoin risk notice, which clearly defined bitcoin as a special Internet commodity, and the public can buy and sell it freely on the premise of taking their own risks

other digital confidential currencies are also suitable, such as Laite coin, the ancestor of Shanzhai coin, Fuyuan coin for business points in jewelry instry, dog coin for small reward, etc. But although virtual currency exists legally in our country, it is illegal to cheat under the guise of virtual currency

extended data

as the proct of e-commerce, virtual currency has begun to play an increasingly important role, and it is more and more connected with the real world. However, with the growth of virtual currency, the relevant laws and regulations are lagging behind, which has laid many hidden dangers

fraud

the private transactions of online virtual currency have realized the two-way circulation between virtual currency and RMB to a certain extent. The activity of these traders is to buy all kinds of virtual currencies and procts at a low price, and then sell them at a high price to earn profits. With the increase of such transactions, there are even virtual mints

in addition to the virtual currency provided by the main company, there are also some people who specialize in "virtual coin making" to obtain virtual currency by playing games and then resell it to other players. Take Wenzhou as an example, there are about seven or eight such "virtual mints" with four or five hundred practitioners. This not only creates a bubble for the price of the virtual currency itself, but also causes trouble for the normal sale of the issuing company. It also provides a platform for selling and collecting money and money laundering for various cyber crimes. p>

impact system

in modern financial system, the issuers of money are generally central banks, which are responsible for the management and supervision of money operation. As the equivalent exchange goods used to replace the real currency circulation on the Internet, the virtual currency on the Internet is essentially the same as the real currency. The difference is that the issuers are no longer central banks, but Internet companies

if the development of virtual currency makes it form a unified market, each company can exchange with each other, or virtual currency is integrated and unified, and all of them are based on the same standard and price, then in a sense, virtual currency is currency, which is likely to form a threat impact on the traditional financial system or economic operation

network problems

in addition to direct cash, virtual currency can also be purchased by SMS, internet transfer and fixed telephone recharge. These ways of purchase not only provide convenience for users, but also have many risks

such as embezzlement of telephone recharge and purchase by minors. In addition, virtual currency does not have the anti-counterfeiting technology of real currency. Computer hackers may use its security loopholes to proce counterfeit currency. Relevant personnel of the State Administration for Instry and Commerce said that virtual currency transaction is a business behavior derived from the Internet era, and there are no clear legal provisions to regulate it, and there are no items related to virtual goods transaction in the scope of instrial and commercial registration

but when the virtual property transaction graally employs people, places are fixed, transaction profits are clear, and has the nature of operation, it may involve market order and tax issues. Even game operators have no ability to control. There are a large number of "counterfeit banknote makers" in the network. Take the winger who is mainly engaged in chess and card online games as an example, the purchasing power of his online currency has shrunk by nearly 40% in one year. Many people point out that such inflation will only damage netizens and make them lose confidence in the Internet

7. I think it's normal for this kind of part-time job to make less and less profits. It's the same for some profitable apps. It's very easy to make money at the beginning, but it's more and more difficult. More and more people are involved

8. Almost every day, the central bank issues and recovers the basic currency. If you go to the people's Bank of China's coffers, you can see that there are a lot of cash in them, but only a small part of them are put into the market (the counters and coffers of residents, enterprises and commercial banks). At present, there may be tens of trillions of banknotes in the people's Bank of China's coffers all over the country, but only two or three trillions of banknotes have been put on the market. What's the main purpose of printing banknotes? It's mainly to prevent depositors from suddenly withdrawing a large amount of cash. There are 20 trillion yuan of household savings in China, but only 2 trillion yuan of banknotes are in circulation in the hands of commercial banks and residents. What if, in case of an emergency, the residents suddenly withdraw all their deposits? Will the commercial banks not let them withdraw? No, the residents can withdraw as much as they want. The commercial banks only move the banknotes to the people's Bank of China, and after the incident subsides, the residents deposit the banknotes in the bank, The bank deposits some of its cash in the PBOC to meet the normal withdrawal of residents. Besides, the remaining depositors increase the bank's reserve balance in the central bank, and the depositors also have interest income. However, when the scale of commercial banks expands, their reserve in the central bank also increases. At this time, the cash of commercial banks may not be able to meet the withdrawal needs of depositors, Commercial banks are forced to scale down because they are punished for failing to pay the required proportion of the central bank's deposit reserve at maturity. It is through these methods that the central bank regulates the economy and stabilizes the currency. However, when all the income and expenditure of residents are transferred electronically, there is no need to use cash. It seems that the deposit reserve system is invalid. I don't know if this is the case. The landlord may want to know how the original cash was put on the market. I think there are many channels. For example, it was first mandatory to stipulate that nothing, including gold and silver, could be used as a medium of exchange except the government printed banknotes. At the beginning, however, residents could use gold and silver to exchange banknotes with the central bank, so that banknotes could be put on the market. With the development of economy, commercial banks create money through the derivative mechanism of deposits. Of course, it is not the base money. As the deposit scale becomes larger, the transaction volume increases, and the required banknotes also increase. The original amount of banknotes can not meet the withdrawal needs of residents. At this time, commercial banks can discount commercial bills to the central bank, so that banknotes will be put on the market again. Then there is the central bank's purchase of bonds issued by enterprises, which also puts the base money on the market. Of course, the central bank can recover the base currency by reverse operation, by legal deposit reserve, and by issuing government bonds. It should be noted that the government purchases goods and pays civil servants salaries with tax money rather than money. If so, it's strange that the banknotes are not rampant.

9. Win10 is better than win7, but there may be a lot of compatibility problems in the early stage of win10. For those who like to play games, if they don't want to make trouble, it is recommended to use win7 first, wait for win10 to mature, and then upgrade
win10 can actually be regarded as the integration and upgrade of win7 and win8. Win10 solves the embarrassment that win8 has no start menu. The return start menu is similar to win7, and improves the upgrade by adding the patch function. In addition, the win10 interface integrates the elegant features of win8, and still maintains the start screen interface. Touch devices or tablet computers can also be used easily
win10 also uses new compression technology, which saves more space than win7. In addition, win10 also has the latest DirectX
12 built in, which can bring better game experience
win7 is perfect, and its stability and compatibility are now the best. It supports almost all software applications and games. As a new generation system, the compatibility of many software and games, including DirectX
12 support, still needs to be optimized and improved by Microsoft and game manufacturers, so win7 has an advantage in the initial compatibility.
