The extent of digital money
1. digital currency facing two risks. The first is the technical level. Digital currency relies on blockchain technology and a system, which will make it suffer from security impact, such as hacker attacks on computer systems. We have seen many practical problems in this process< Another risk of digital currency is credit risk. Because there are middlemen in digital currency transactions, these middlemen are different from real organizations. In reality, organizations can be seen and felt, but the middlemen of digital currency are on the Internet, so the risk is greater
3. Digital currency has the characteristics of anonymity, quickness and irrevocability. In addition, bitcoin and other digital currencies have high circulation in the world, so many criminals use digital currency as a new money laundering channel. Moreover, there are many different ways to realize money laundering through digital currency. Generally speaking, the probability of new money laundering being found and investigated is lower than before. Many countries have no effective means and technology to combat money laundering through digital currency. These factors lead to criminals prefer this way of money laundering
investment is risky and business should be cautious
the digital currency launched by the central bank is a national sovereign currency, which is based on the digitalization of RMB. This is a piece of data generated by a complex algorithm, which contains blockchain and encryption technology, making it unique. The payment of Alipay and WeChat is not digital money, but only based on the payment realized by electronic accounts. Compared with the current pattern of "payment transfer collection" with the help of third-party payment, what digital currency needs to achieve is "decentralization", that is, to cancel the transfer link and directly hand over the money from the payer's account to the payee, so as to rece the payment cost in currency circulation
types of digital currency
according to different issuing or consensus mechanisms, it can be divided into four categories:
1, proof of work (POW)
proof of work. The system rewards are obtained through the mining of computing power to complete the issuance and distribution of currency. More work, more gain. Such as bitcoin, lightcoin (LTC)
the advantage is that the mining cost can form a monetary price support to a certain extent, and the disadvantage is that energy consumption and environmental protection are criticized< 2. Proof of stake (POS). Allocate the newly generated currency or interest according to the amount and time of cryptocurrency you hold. Such as dash and Neo
compared with pow, POS is more energy-saving, but it increases the security risk
3. The evolution scheme of delegated proof of stake (dpos)
POS. Similar to the voting mechanism of the board of directors, through the election of representatives to vote and make decisions, n accounting nodes are elected to create, verify, sign and supervise each other. Such as the grapefruit coin (EOS)
the advantage is high efficiency, but the problem is that it presents a semi centralized state
4. POW + POS hybrid mechanism
POW is mainly used to issue currency, and POS is used to maintain the system. For example, PPC
according to the project type, it can also be divided into four categories:
1. Currency category
digital currency issued for the purpose of transfer, payment and value storage. For example, bitcoin, bitcoin cash (BCH), Monroe (XmR), and grin
2. Public chain currency, that is, the digital currency issued by public chain projects, is generally the "fuel" for the application projects to run on the public chain. Such as eth, grapefruit coin, TRX and ont
3. Application token, that is, digital currency issued by decentralized application projects, is equivalent to equity or points. For example, OMG (payment application), GXC (data application), 1st (game application)
4. Platform currency, that is, the digital currency issued by the digital currency exchange, is equivalent to equity, points or fuel. For example, BNB, HT and okb.
Digital money drives economic consumption. People have no concept of money, only material needs. At the same time, digitization facilitates people's communication
the replacement of paper money by digital currency can only be realized in the eastern coastal developed areas and some big cities, but it is unrealistic in some remote areas, and the infrastructure can not keep up
bitcoin, lightcoin and decent are known as global circulation, but in fact, the scope of circulation is very limited.
1. For commercial banks and other financial institutions, it is both an opportunity and a challenge. In the future, more innovations such as digital credit, digital assets and digital liabilities will be derived from digital currency, while the non sovereign "digital right currency" will graally cool down. In addition, the central bank can improve the efficiency of monetary operation monitoring and enrich monetary policy means after the issuance of digital currency
2. Issuing the legal digital currency of the central bank will make it possible to collect the data of money creation, bookkeeping and flow in real time. After data desensitization, it will conct in-depth analysis through big data and other technical means, so as to provide a useful reference for money supply, formulation and Implementation of monetary policy, and provide a useful means for economic regulation and control
extended data:
characteristics of digital currency
Central Bank digital currency is quite different from electronic payment in some functions. In the past, the fund transfer of electronic payment instruments must be completed through the traditional bank account, which adopts the way of "account tightly coupled"
and the central bank's digital currency is "account loose coupling", which can be separated from the traditional bank account to realize the value transfer and greatly rece the dependence of the transaction link on the account. The digital currency of the central bank can be as easy to circulate as cash, which is concive to the circulation and internationalization of RMB. At the same time, it can realize controllable anonymity
