Implementation of digital currency in Yangtze River Delta
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
Nowadays, with the development of the Internet age, the era of digital currency is coming. Digital currency obviously provides convenience for people's life, and there are many advantages. However, digital currency has no advantages of real currency and no interest{ RRRRR}
Third, digital currency has no interestbut the promotion of digital currency also has certain obstacles, for example, our payment platform today, and these mobile payment also need network, once the network problems, then even can not complete the payment. However, digital currency is different, not only does it need no network, but also will not be limited by time and space, and even does not need handling charges< it's just that digital currency has no interest of real currency, which is also the case that many people are reluctant to use digital currency
In early 2014, the Central Bank of China set up a special research group on legal digital currency to demonstrate the feasibility of issuing legal digital currency by the central bank. On January 29, 2017, the central bank officially established the digital currency Research Institute. After the successful development of the prototype of legal digital currency, the digital currency Research Institute of the people's Bank of China has tried to deploy institutions in many parts of the country, and through the integration with R & D institutions and instries, it has achieved the research results of financial development technology. In 2018, the digital currency Research Institute of the people's Bank of China successively settled in Nanjing and Shenzhen. In 2019, the people's Bank of China announced that digital currency will be piloted in Shenzhen, Suzhou, Cheng and xiong'an

the research on Shenzhen's support for digital currency began in 2016

DSL is the abbreviation of digital subscriber line, which is a technology to greatly improve the digital capacity of ordinary telephone line (local loop) entering the home or office. The speed of DSL is limited by the distance between the user and the telephone office
DSL is oriented to two kinds of applications. Asymmetric DSL (ADSL) is used for Internet access which needs higher downlink speed. Symmetric DSL (SDSL, HDSL, etc.) is designed for short-range connection which needs two-way high-speed communication
DSL provides high-speed data transmission on the "last mile" of the so-called telephone network "local loop" (that is, the twisted pair copper wire line connecting home and small office users to the telephone company Central Office (CO)). With the development of Internet access, e-commerce, IP phone and video conference, the demand for high-speed access methods is also growing
extended data:
working principle of DSL
at the beginning of the design of telephone system, it was mainly used to transmit voice calls. For economic considerations, the telephone system was designed to transmit signals in the frequency range of 300Hz to 3.4khz (although people's voice can reach 15KHz, it is still very easy to identify each other in this range)
However, the copper cable from the local telephone network to the end user can actually provide a higher bandwidth, at least from the lowest frequency to 200-800khz, which depends on the circuit quality and the complexity of the equipment (it is generally believed that the less the connection to the end user's splitter, the better the bandwidth, and the environment where the line is passing by, The smaller the electronic interference, the better the line bandwidth By using the additional frequency band of telephone line, DSL successfully overcomes the problem of transmitting a large amount of data on the audio tape (see Shannon's theorem). DSL service usually reserves the frequency band of 0.3-4khz for voice service, that is, the frequency band used by the so-called ordinary old telephone service ({Lang | en | pots}), and uses the frequency outside this range to transmit data The DSL connection is established between the DSL modem of the user equipment and the telephone switch, and then the switch establishes a connection with the (typical) ISP that the user really wants to connect to through some other protocol. This is different from the common public telephone network and the end-to-end telephone connection. If the distance between the subscriber and the switch is more than 5.5km, the quality of service will drop sharply e to interferenceSince China began the construction of digital RMB, the United States has been using & lt; Long term threat; China's digital RMB development is closely watched
while many countries are consciously carrying out research on the digitalization of local currency, China has begun to test the water in this field{ RRRRR}
he believes that digital RMB can be applied to international payment with good convenience and high security
Digital RMB has the purpose of improving international payment. In international trade settlement, digital currency is more secure, reliable and convenient
please accept, thank you!
since 1979, Guangdong has become a test field for reform and opening up (reason: close to Hong Kong and Macao, far away from the central area of mainland China, economically lagging behind other provinces in mainland China)< In 1979, the central government announced that Guangdong and Fujian provinces would be allowed to implement special policies and set up special economic zones in Shenzhen, Zhuhai, Shantou and Xiamen. After the promulgation of a series of rules in 1980, the special economic zone was formally established< After Deng xiaoping visited the south in 1984, Guangzhou, together with other 13 coastal cities, gained greater autonomy in foreign trade and investment
in 1988, Guangdong was designated as the "Comprehensive Experimental Zone of economic system reform" and gained greater autonomy< In 1992, Deng xiaoping visited the South and affirmed Guangdong's vanguard role in the process of China's economic reform. Call on Guangdong Province to speed up reform to catch up with other developing Asian economies
