Flow chart of issuing digital currency
at present, the so-called issuance of legal digital currency in the Internet, and the behavior of indivial institutions launching "DC / EP" or "DCEP" in the name of the people's Bank of China to conct transactions on the asset trading platform may involve fraud and pyramid selling. The general public should raise their risk awareness, not be partial to trust, and guard against interest damage
as early as September 4, 2017, the central bank and other seven departments jointly issued the announcement on preventing the financing risk of token issuance (hereinafter referred to as the announcement), pointing out that the issuance of virtual currency, ICO and other suspected illegal financial activities seriously disrupted the economic and financial order, and no organization or indivial may engage in the above activities illegally.
we speculate that once the central bank issues digital currency in the future, the periphery of the structure must be a decentralized system. At present, blockchain is the best choice
when talking about digital currency, the central bank also mentioned another concept, which is called programmable currency. How to understand? For the computer, it has a certain internal self-control function. Take the early object-oriented language as an example, it requires at least two functions, one is the constructor, the other is the destructor. You have to solve the problem of its creation as well as its extinction
through programming, the central bank can control the whole life cycle of money creation, circulation and withdrawal
in the absence of digital currency and programmable currency, the currency issued by the central bank circulates freely in the society. How to return to the cage in the end? One is the return of derivative currency of commercial banks, the other is the return of basic currency of central bank. The former is controlled by the central bank through deposit reserve and other policies, while the latter is controlled by the tax system. If we go up to programmable digital currency in the future, the central bank will have much more control. Even in circulation, control can be increased. That's why central banks are very interested in blockchain technology.
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.
the first country to recognize bitcoin as legal was Germany, which first defined bitcoin as an alternative currency. Of course, in the future, sovereign digital currencies may be popular, and digital cryptocurrencies such as bitcoin, Ruitai coin, Laite coin and vitality coin will become a supplement.
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
