extended information:

the central bank said that the so-called "digital currency" in the market is not legal digital currency:

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

the central bank said that the central bank has not issued legal digital currency, nor authorized any institutions and enterprises to issue legal digital currency, and there is no promotion team. At present, the so-called "digital currency" in the market is not legal digital currency. The central bank also suggested that the so-called "digital currency" launched by some institutions and enterprises and the so-called promotion of the central bank's issuance of digital currency may involve pyramid selling and fraud

in fact, virtual currencies such as bitcoin and lightcoin are representatives of the so-called digital currency. The central bank said in 2016 that it was studying China's legal digital currency. Yao Qian, director of the digital currency Research Institute of the people's Bank of China, previously told the media that the prototype scheme for the central bank to issue legal digital currency has completed two rounds of revision, and is expected to be tested in relatively closed application scenarios such as the bill market in the future, but there is no clear timetable for its launch

ways to purchase digital currency:

at present, digital currency is more like an investment proct. Due to the lack of a strong guarantee institution to maintain its price stability, its role as a measure of value has not yet appeared, nor can it be used as a means of payment. As an investment proct, the development of digital currency is inseparable from trading platforms, operating companies and investors

trading platforms play the role of trading agents, while some play the role of market makers. The profits of these trading platforms come from the current expenses and premium income of investors trading or holding digital currency

1. Investors need to register accounts first, and obtain digital currency accounts and US dollar or other foreign exchange accounts at the same time

2. Users can use the money in their cash account to buy and sell digital currency, just like buying and selling stocks and futures

3. The trading platform will sort the buying and selling requests according to the rules and start matching. If the requirements are met, the transaction will be completed

4. Due to the difference between the trading volume submitted by users, the trading request can be partially executed

take RBM operated by professional operation company opencoin as an example: ripple protocol was originally designed based on payment method, and its design idea was based on acquaintance relationship network and trust chain. Using ripple network for remittance or loan, the premise is that the payee and the payer must be friends or have common friends. Otherwise, the trust chain between users and other users cannot be established, and the transmission cannot be carried out

the characteristics of digital currency are as follows:

1, low transaction cost

compared with traditional bank transfer, remittance and other methods, digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with the cross-border payment of high handling charges to payment service providers

2, fast transaction speed

the blockchain technology used in digital currency has the characteristics of decentralization, and it does not need any centralized organization similar to the clearing center to process data, so the transaction processing speed is faster

3, high anonymity

in addition to the physical form of currency can achieve peer-to-peer transactions without intermediary participation, one of the advantages of digital currency compared with other electronic payment methods is that it supports remote peer-to-peer payment, and it does not need any trusted third party as intermediary

both sides of the transaction can complete the transaction in a completely strange situation without mutual trust, so they have higher anonymity and can protect the privacy of the traders, but at the same time, they also create convenience for cyber crime, which is easy to be used by money laundering and other criminal activities

3. It's illegal to buy and sell digital currency, because no matter whether it's a good digital currency or a currency in circulation in reality, you can't buy and sell it casually

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

< H2 > after modification, you can use ifconfig command to check whether the modification is successful
