Digital currency and sovereign currency
fiat money: it means that it does not represent real goods or goods, and the issuer has not cashed the currency into physical obligation; A currency that becomes legal currency only by government decrees. The value of fiat money comes from the owner's belief that money will maintain its purchasing power in the future. Money itself has no intrinsic value, that is to say, when the paper money comes into being, legal tender is essentially the negotiable paper money stipulated by law
the legal currency of the people's Republic of China is RMB, and the people's Bank of China is the national authority in charge of the management of RMB, which is responsible for the design, printing and issuance of RMB—— From the Internet
e-money: in fact, it is the electronization of legal money, including our common bank card, online banking, e-cash, etc; There are also third party payments developed in recent years, such as Alipay and WeChat payment. No matter what the form of these electronic money is and through which institutions it circulates, its original source is the legal money issued by the central bank
virtual currency: virtual currency refers to non real currency, and its existing state is intangible. The most important difference between virtual currency and electronic currency in narrow sense is the difference of issuers. Virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. For example, game currency, q-coin, and ticket counting are mainly limited to circulation in a specific virtual environment
digital currency: digital currency which applies the latest digital network technologies such as blockchain, has the characteristics of Distributed Accounting, unique encryption technology, decentralized settlement, etc. Of course, digital tools with these characteristics must be supported by national credit if they want to become sovereign currency or legal tender
therefore, digital currency must be currency; In today's social system, money must also be sovereign money or legal tender. Secondly, digital currency must have the basic attributes and main functions of currency.
1、 Different definitions:
1. Virtual currency:
virtual currency refers to non real currency
Digital currency:digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

4. Token (token):
a kind of article whose shape and size are similar to currency, but the scope of use is limited and has no currency effect, and its token is the homonym of token in English
Second, the characteristics are different:1; It can also be said that virtual currency is personalized currency. In another way, it can also be called information currency
2. Digital currency:
is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities
Cryptocurrency:cryptocurrency is based on the decentralized consensus mechanism, which is opposite to the banking and financial system relying on the centralized regulatory system
4. Token (token):
usually needs to be exchanged for money, used in shops, playgrounds, mass transportation and other places, as a voucher to use services and exchange goods
extended data
at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company
digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability
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.
unlike virtual currency, digital currency is neither bitcoin nor q-coin! That is to say, it is different from virtual currencies such as bitcoin and Ethernet
virtual currency can only be closed in circulation on the network, just like Tencent's q-coin and Huixin cloud software collaborative instry ecological chain platform, they can only be used for their own procts. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency, bitcoin is illegal digital currency. As for legal digital currency, there is no unified international definition. Yao Qian, deputy director of the science and Technology Department of the people's Bank of China and head of the preparatory group of the digital currency Research Institute, believes that the digital currency researched and issued by the people's Bank of China is indexed RMB. From the perspective of national schemes, it belongs to legal encrypted digital currency, which is not only a payment tool but also a currency. Correspondingly, virtual currency is also called illegal fixed digital currency. Li Lihui, head of the blockchain working group of China Internet Finance Association, once said that digital currency must have legal status, national sovereignty endorsement, and clear responsibility subject of issuance. Virtual currencies represented by bitcoin and ethereal currency have no country, no sovereign endorsement, no qualified issuers, and no national credit support. These are not digital currencies
digital money is not equivalent to virtual currency
since digital money can be used for commodity trading, is Alipay and WeChat payment a kind of digital currency?
Alipay, WeChat payment and mobile phone banks are all electronic money, not digital money. These are all payment methods based on electronic accounts, which are in essence just a process of informatization of legal currency, not digital currency in a strict sense. For example, the amount of Alipay or WeChat transactions is essentially banknotes on bank accounts, but it is electronic form. The "100 yuan" displayed on the mobile phone will correspond to the real 100 yuan in the bank.

1. Legal digital currency: in essence, it is still the debt issued by the central bank to the public, which belongs to a form of digital currency. Legal digital currency should be the digital currency with legal status, which is the main body responsible for the issuance of national sovereignty.
2. Digital currency: virtual currency is represented by bitcoin and ether currency, which is not issued by central institutions, It has the characteristics of anonymity. It is not under the existing legislation, so it can not be recognized as money and has no monetary value.
Digital money (electronic money or electronic currency) is a kind of money in digital form (different from paper money and coins). It shows properties similar to physical currency, but allows immediate transaction and boundaryless ownership transfer. Examples include virtual currency, cryptocurrency and currency issued by central bank and recorded in computer database (including digital base currency). Like traditional currencies, they may be used to buy physical goods and services, but they may also be restricted in some communities, such as online games
