China does not issue digital currency, and all the existing digital currencies are illegal

the central bank pointed out that no legal digital currency has been issued, and no institutions and enterprises have been authorized to issue legal digital currency. At present, the so-called "digital currency" in the market is not legal digital currency

virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency

"the legal currency of our country is RMB." In the risk warning, the monetary Bureau of the people's Bank of China once again stressed that RMB is uniformly printed and issued by the people's Bank of China

extended information:

with the soaring price of virtual currency represented by bitcoin, digital currency and the blockchain technology behind it have attracted great attention of the global financial community. In fact, legal digital currency has not yet been issued in China. Recently, the official website of the monetary Bureau of the people's Bank of China (PBOC) released the risk warning on issuing or promoting digital currency in the name of the people's Bank of China

in 2013, the central bank, together with five ministries and commissions, issued the notice on prevention of bitcoin risks, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, which do not exist in the form of currency and legal currency

At the same time, digital money is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized

such as Internet banking, WeChat, Alipay and other payment electronic popularization graally, physical cash accounts for only a very small part of all circulating currencies. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotes

currently, digital currency in the market involves multi-level marketing

digital currency is a new technology that can improve the efficiency of transaction, but it is targeted by lawless elements to carry out pyramid selling and fraud in its name

the official website of the monetary Bureau of the people's Bank of China issued the risk warning on issuing or promoting digital currency in the name of the people's Bank of China. The central bank pointed out that recently, indivial enterprises falsely used the name of our bank to label relevant digital procts as "authorized issuance by the people's Bank of China", or falsely claimed that the digital currency promotion team of the central bank issued, in an attempt to deceive the public and take the opportunity to make huge profits

in the risk warning, the central bank stressed that the bank has not issued legal digital currency, nor authorized any institutions and enterprises to issue legal digital currency, and there is no promotion team.

3. Digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

4. Bitcoin, of course, is the hottest one. In addition to bitcoin, there are also:
1. Litecoin is similar to bitcoin, which is also an encrypted digital currency, and its price has risen sharply recently. It is a P2P open source digital currency, which can be regarded as a branch of bitcoin. However, although lightcoin is based on bitcoin protocol, it does not require very high computing power. It can also be mined using ordinary computers. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
2. Namecoin
namecoin is also based on bitcoin, which is another branch of open source. Namecoin is a distributed DNS protocol -- generally speaking, it can transform the website name (such as ifeng. Com) that can be understood by human into the address that can be understood by machine. As its own DNS, this kind of currency can operate outside the normal Internet, so it can break away from the control of ICANN
the monetary value and domain name of namecoin are stored in the user's blockchain records, limiting the total number to 21 million
3. Peercoin
peercoin is a peer-to-peer variant of bitcoin, which can improve mining efficiency and security, and improve safeguard measures to avoid group mining. Now, group mining has been considered as a potential defect of bitcoin. According to the statistics of emerging currencies by coinmarketcap.com, peercoin currently ranks fourth in the market value of digital currencies
4. Primecoin
primecoin is a cryptocurrency similar to bitcoin, but it uses a completely independent mining algorithm. Bitcoin uses the hashcash algorithm, while prime coin uses the long Cunningham chains to create the value of money - a sequence of prime numbers named after mathematician AJC Cunningham
in the process of bitcoin mining, as the amount of money goes on, the difficulty will increase sharply. But prime is different. Every time a primecoin is mined, the mining difficulty will increase slightly, and the process is much more stable< 5. Feathercoin

based on the design of litecoin, released in April 2013, can adjust the mining difficulty more frequently than litecoin. Feathercoin will be updated frequently, adding new features and improvements to eliminate malicious mining behavior

6. Novacoin

another P2P digital cryptocurrency. Novacoin is different from most other currencies in that it integrates a protection mechanism in the currency core, which can identify illegal mining activities

the total number of novacoin is limited to 2 billion, which is considerable. If necessary, the total can be adjusted upward

7, infinitech

published in June 2013. A by-proct of litecain. According to the mining situation and the total amount of money, infinite money can frequently adjust the mining difficulty ratio< Megacoin was only released in the fourth quarter of 2013, imitating bitcoin in the early stage. The total number of megacoin is limited to 42 million, which can be mined like other virtual currencies. Its biggest selling point is brand publicity, which other digital currencies lack< It was released in 2013 and is still in its infancy. In the security part of quarkcoin, nine independent loops are deployed and six different algorithms are used.

Generally, the excellent digital currencies are mostly imported procts, such as bitcoin, Leyte coin, ether coin and so on. However, the domestic Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects of European crowdfunding are excellent digital currencies

advantages of digital currency:

1. Save cost and improve efficiency

in the traditional electronic payment process, funds are stored in the third-party platform. The third-party platform deposits funds through the time difference of payment to obtain short-term interest income, which makes customers and businesses suffer losses, and the transaction process has two capital transfers, which makes the transaction process rendant. Electronic payment based on blockchain technology eliminates the third-party platform and realizes peer-to-peer payment (P2P), which simplifies the payment process and reces the payment cost

2. Optimize the traditional payment function

digital currency can inherit the advantages of cash payment (point-to-point payment, instant payment and settlement, convenient and fast), and solve the defects of cash at the same time. In this condition, controllable anonymity can be realized at the same time. That is to say, compared with traditional mobile payment, digital signature is used to effectively protect the personal information of each participant, so as to prevent the loss, leakage or malicious tampering of the user's personal information

3. Control the whole life cycle of currency and control the return of currency

The economist Stiglitz studies the macroeconomic management of e-money system, and points out that the electronization and digitalization of money will help to improve the ability of central bank to monitor money flow and organize market, and improve the effectiveness of monetary policy. More importantly, legal digital currency will create a new price based monetary policy tool, which can break the zero interest rate lower limit and release monetary policy space

Digital currency does not rely on physical outlets and labor services, and has low cost of infrastructure and human resources. It can obtain a larger service capacity with less material and human input, which is concive to the expansion of financial services in remote and poor areas. Moreover, financial services based on digital currency have the characteristics of small amount and convenience, such as "massive transactions, small and micro single amount", which create conditions for the general public to facilitate life and increase employment

1. Bitcoin

the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

2. Litecoin (LTC) is an improved version of digital currency inspired by bitcoin. It was designed and implemented by a programmer who worked in Google. It was released on November 9, 2011. Lightcoin and bitcoin have the same implementation principle in technology, but the creation and transfer of lightcoin is based on an open source encryption protocol, which is not managed by any central organization

extended data

characteristics of bitcoin currency:

1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom

2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution

This is a Linux system IP address configuration command. The specific meaning is:

set the IP address of the system to 192.168.0.2; The subnet mask is 24, that is 255.255.255.0; The broadcast address is 192.168.0.255; The name of NIC device is eth0

all computers in the network must set a unique IP address to communicate normally. Because of this unique address, users can select the objects they need from thousands of computers efficiently and conveniently when they operate on networked computers

The IP address is just like our home address. If you want to write to a person, you need to know his or her address so that the postman can deliver the letter. A computer sending information is like a postman. It must know the only "home address" to avoid sending the letter to the wrong person. But our address is expressed in words, the address of the computer is expressed in binary numbers

eth0 is the name set by the system for the network card. If there are al network cards or multiple network cards, there will be names like eth1 and eth2. The name can be set artificially. It is the unique name of the network card in the current computer system
