Opening area of digital currency
there is no . In response to the online transmission of China Construction Bank mobile app online digital currency in personal wallet, CCB responded on the evening of August 29 that CCB carried out relevant function test in mobile banking system on the evening of August 28, at present, this test has ended . At present, Internet information is the testing content in the process of technology research and development, does not mean that digital RMB is officially launched
it is reported that recently, the app of China Construction Bank launched the digital currency wallet, which surprised people. Users only need to bind their own bank card on the digital currency wallet to open it. In addition, the app of China Construction Bank has added two submenus of digital wallet recharge and digital currency, indicating that users can use the digital RMB wallet to recharge, It is mainly divided into app wallet and hardware wallet

many companies speed up the layout
recently, there are many rumors about digital RMB, which are also reflected in the capital market. Judging from the performance of the digital currency sector, it recently hit a new high this year
some listed companies revealed that they would pay attention to the field of digital currency and actively lay out their plans. On the e interactive platform of Shanghai Stock Exchange, Qi an Xin said that the pilot test of digital currency has brought more market opportunities for security manufacturers from the new security project opportunities brought by the upgrading of financial IT system, and the company has been paying attention to and actively arranging
The company has been paying close attention to and actively following up the technology and application trends related to digital currency, and has continued to make layout in technology R & D and proct development. In the process of promoting the implementation of digital currency by the central bank, Youbo will also contribute to the digitalization of RMB and the implementation of offline merchant payment scenariosShenzhou Holdings said in the China Daily News that its Shenzhou information has participated in the central bank's digital currency (DC / EP) test and related promotion work of a commercial bank, involving the electronic payment scenario test of encrypted digital currency. As one of the important systems required for the later promotion of DC / EP, Shenzhou information has completed relevant technical reserves, In the future, it can help commercial banks realize the implementation and promotion of digital currency
Hello, where are the first batch of pilot cities of the central bank's digital currency? Do you think they are well deserved super first tier cities "Beijing, Shanghai, Guangzhou and Shenzhen"? I want to tell you that it's not all right. Except Shenzhen, the other three cities are Cheng, Suzhou and xiong'an new area. At present, Shenzhen is the earliest city to launch digital currency. On October 9, Shenzhen issued 10 million digital currency. 50000 people, 200 yuan per person, can enjoy the welfare, which is distributed to everyone free of charge through the way of wagging number. Here, I can only envy you. The implementation of digital currency is so fast. The friends in the pilot cities are lucky. I just want to watch you win the lottery
the first batch of pilot cities are selected in these four cities, which is the first step for digital currency to go to the whole country. When it matures in the future, it will be promoted to more pilot cities. So don't worry, just wait. Even if our city is not a pilot, it doesn't matter. Next time it will be our city. The pilot is just to test the stability of the system, and we don't have a great chance to get the red envelope of digital currency. There are so many people in Shenzhen, and only 50000 numbers are selected. Here we would like to express our support and thanks to the cities selected as the pilot cities of digital currency
ways to purchase digital currency:
at present, digital currency is more like an investment proct. Due to the lack of a strong guarantee institution to maintain its price stability, its role as a measure of value has not yet appeared, nor can it be used as a means of payment. As an investment proct, the development of digital currency is inseparable from trading platforms, operating companies and investors
trading platforms play the role of trading agents, while some play the role of market makers. The profits of these trading platforms come from the current expenses and premium income of investors trading or holding digital currency
1. Investors need to register accounts first, and obtain digital currency accounts and US dollar or other foreign exchange accounts at the same time
2. Users can use the money in their cash account to buy and sell digital currency, just like buying and selling stocks and futures
3. The trading platform will sort the buying and selling requests according to the rules and start matching. If the requirements are met, the transaction will be completed
4. Due to the difference between the trading volume submitted by users, the trading request can be partially executed
take RBM operated by professional operation company opencoin as an example: ripple protocol was originally designed based on payment method, and its design idea was based on acquaintance relationship network and trust chain. Using ripple network for remittance or loan, the premise is that the payee and the payer must be friends or have common friends. Otherwise, the trust chain between users and other users cannot be established, and the transmission cannot be carried out

the characteristics of digital currency are as follows:
1, low transaction cost
compared with traditional bank transfer, remittance and other methods, digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with the cross-border payment of high handling charges to payment service providers
2, fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization, and it does not need any centralized organization similar to the clearing center to process data, so the transaction processing speed is faster
3, high anonymity
in addition to the physical form of currency can achieve peer-to-peer transactions without intermediary participation, one of the advantages of digital currency compared with other electronic payment methods is that it supports remote peer-to-peer payment, and it does not need any trusted third party as intermediary
both sides of the transaction can complete the transaction in a completely strange situation without mutual trust, so they have higher anonymity and can protect the privacy of the traders, but at the same time, they also create convenience for cyber crime, which is easy to be used by money laundering and other criminal activities
digital currency has four common functions: "scan code to pay", "remittance", "collection and payment", "touch one touch"
the pilot cities are Shenzhen, xiong'an, Cheng and Suzhou
the glorious revolution. The king's name is William III and Mary II. Mary is the daughter of James II of the Stuart dynasty. William III was originally in power in the Netherlands. Mary's husband also has the blood of Stuart family. James II is a Catholic, trying to restore the status of Catholicism in England. When James II ascended the throne, he was very old. At that time, it was generally believed that his Protestant daughter would inherit the throne after James II died (when James had no son). The Whig party, which controlled the Parliament, thought that this would not affect the status of the Church of England, But later, James II united with the king of France to try to restore the status of Catholicism in Britain and the power of the king. At that time, Britain and France were hostile to each other, and Louis XIV's foreign expansion policy made the Netherlands, Britain and other countries united against France. James II's practice intensified the conflict between the king and the parliament. During this period, James II got a son in his old age, which made England under the leadership of a Catholic king in the future. Worried that it would harm the interests of Britain, Parliament planned to make Anne and William king of England. On the other hand, it was ring the so-called great alliance War (the nine-year war, see Cambridge Modern World History, omitted here) that William, the ruling Dutch, urgently needed the strength of Britain to help him fight against France, so that his plan could be carried out. James II fled to France and Ireland when he learned that the Parliament had given William the throne. With the support of France, he organized an army to attack the British army. Later, he was defeated in Ireland and fled to France. Later, the British Parliament passed a series of laws to consolidate this form. The British double king rule lasted until 1694 (Mary II died). In 1702, Anne, another daughter of James II, succeeded to the throne. After Anne died, the throne was transferred to Hanover, Germany, and the Stuart dynasty ended.
F= ρ S(v*sin θ)^ 2
the formula is deced as follows:
consider the case that the wind speed is perpendicular to the action surface first
take the cross section of the wind as s and the length as S Δ x( Δ x-> 0), and the velocity before the wind contacts the action surface is v Δ x=v Δ T
the mass of the air column is Δ m= ρ S Δ x= ρ Sv Δ T
because the mass of the air column is very small, when it collides with the action surface, it will move along the action surface, that is, its velocity perpendicular to the action surface is 0 Δ t=0-(- Δ MV)
i.e. F Δ t= ρ Sv Δ t*v
F= ρ When the wind speed is not perpendicular to the action surface, the velocity is divided into the direction of the vertical action surface and the direction parallel to the action surface. Since the component parallel to the action surface will not generate force with the action surface, the final wind force is only the component perpendicular to the action surface, which is v * sin θ, Substituting this formula into (*) to get
F= ρ S(v*sin θ)^ two
