The issue mechanism of digital currency in China
On November 9, 2019, the central bank has not launched digital currency
in 2014, the Central Bank of China set up a special research team to conct in-depth research on the framework of digital currency issuance and business operation, key technologies of digital currency, issuance and circulation environment, and legal issues
in January 2017, the central bank officially established the digital currency Research Institute in Shenzhen
in September 2018, the Institute of digital currency built a trade finance blockchain platform
On July 8, 2019, at the launching ceremony of the digital finance open research program and the first academic seminar, Wang Xin, director of the Research Bureau of the people's Bank of China, disclosed that the State Council has officially approved the research and development of the central bank's digital currency, and the central bank is engaged in corresponding work in organizing market institutions

benefits of digital currency
the digitalization of central bank's currency helps to optimize the central bank's monetary payment function, improve the central bank's monetary status and the effectiveness of monetary policy. The central bank's digital currency can become an interest bearing asset to meet the holder's reserve demand for safe assets, and can also become the lower limit of bank deposit interest rate. It can also become a new monetary policy tool
at the same time, the central bank can affect the bank deposit and loan interest rate by adjusting the digital currency interest rate of the central bank, and help to break the zero interest rate lower limit
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
in addition, Zhou Xiaochuan also mentioned that there is a lot of discussion about "51% attack" (assuming that indivials have 51% of the computing speed of the whole network, they can realize double payment, reverse transactions, paralyze the whole network, and completely lose the transfer function). More specifically, compared with the special currency, bitcoin does not need the central bank. Zhou Xiaochuan mentioned that for the digital currency controlled by the central bank, a series of technical means, mechanism design and laws and regulations will be adopted to ensure the security of the digital currency operation system, which is different from the design idea of bitcoin from the beginning
as for the digital currency timetable, Zhou Xiaochuan said that there is no established timetable. The relationship between digital currency and cash will be parallel and graally replaced for quite a long time. For reference.
It is not currently available
at present, the Central Bank of China has not issued and approved the digital currency of issuers and investors
However, at the beginning of the year, the central bank held a seminar on digital currency, at which it made it clear that it was necessary to issue digital currency as soon as possible, and the central bank put the issue of digital currency on the agendahowever, so far, the central bank has not issued any digital currency, and Zhou Xiaochuan, the governor of the central bank, said that the time is not ripe to issue digital currency. Moreover, the digital currency issued by the central bank is different from bitcoin, Ruitai, Laite and other digital cryptocurrencies, and the digital currency issued by the central bank is not decentralized
when the central bank issues digital currency, it needs to establish a basic digital currency system. In this system, the central bank is in charge of the digital currency issuing bank, the commercial bank is in charge of the bank, and the public and indivials hold digital wallets. This is not much different from the existing monetary system in essence, but the managed currency is changed from paper money to digital cryptocurrency
in terms of issuing mechanism, there are two modes:
one is the traditional mode of "central bank commercial bank", that is, the central bank issues digital currency from the issuing bank of the central bank to the Bank of the commercial bank. When an indivial withdraws money from the commercial bank, the digital currency is transferred from the commercial bank to the personal digital wallet
another mode is the "central bank public" mode, that is, the central bank can directly issue digital currency from the currency issuing bank to the digital wallet of the public and indivials. In essence, no matter which issuing mode, money is ultimately held by the public, which is the debt of the central bank to the public
we are ready to discover digital currency, but it is still in the planning and brewing stage, and there is no formal issue
this project will upgrade the existing currency discovery mechanism, and each unit of currency is given its own special identification mechanism
in addition, the bank account, Zhang Sanhui gives you 100, Li Sihui gives you 100, under the current system, there is no essential difference between the two 100, For you, for the system, the bank account is the same bookkeeping symbol, but under the digital currency mechanism, the system can correctly identify which unit currency, that is, the 200 yuan, is given by Zhang San and which by Li Si. Note that this is in the electronic system, not the actual paper currency, which is equivalent to giving DNA to each unit currency

this problem is very professional
