Central bank digital currency control

1. It is very clear in the speech of the central bank that the digital currency is M0. What is M0? M0 is cash. We speculate that the basic framework for the central bank to issue digital currency in the future should be a two-tier structure. The core is the database of the central bank, and the periphery is the blockchain of different instries, regions and third parties. Why? Only by using a decentralized system in the second layer can you ensure that the money is controlled by the users themselves and that the digital currency really becomes M0

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.

On March 28, the central bank held a national teleconference on monetary gold and silver work in 2018. Fan Yifei, vice governor of the people's Bank of China, pointed out that we should further strengthen reform and innovation and solidly promote the research and development of digital currency of the people's Bank of China. We should strictly strengthen internal management and external supervision, attach great importance to and effectively strengthen the quality control of RMB, carry out large amount cash management, build a cash clearing enterprise supervision system in accordance with the law, carry out the rectification and clean-up of all kinds of virtual currencies, and strive to build a "five in one" anti-counterfeit currency working mechanism

from the perspective of global digital currency regulatory practice, China has adopted a more stringent regulatory approach, but it does not mean that China can stay out of the global financial innovation wave. In the future, China should actively participate in the global governance of digital currency and enhance its influence and voice in the development of digital currency and regulatory rules

3. A decentralized digital currency storage scheme is provided for users. The wallet key and the address and private key information of all kinds of currencies are stored in the user's local system. At the same time, the wallet provides a convenient key backup scheme - users only need to backup once and save it in a safe place. Even if the types of digital currency are added subsequently, all types of digital currency assets can be recovered with backup. In addition to allowing users to fully control the key of the wallet, the wallet also provides multi signature technical support and two-step authorization verification for digital asset management of different scales. Users can choose mobile phone verification code, fingerprint, living body and other verification methods ring transfer transactions to ensure the security of digital currency assets in an all-round way.

4. Fire money, a blockchain digital currency, is illegal in China. There is no operating license.

5. First, change the amount of money

to regulate the money supply through open market operation
change the interest rate of central bank loans to commercial banks
secondly, it affects the reserve ratio
adjusts the statutory reserve ratio
changes the Reserve interest
