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
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
The people's Bank of China has not issued digital currency for the time being, so there is no legal digital currency in China at present. At present, digital currency has not been recognized in China, let alone legal
at present, all kinds of digital currencies circulating in the market are basically on the edge of the law. China maintains a neutral attitude, but does not like speculation, which is also the basic attitude of the central bank{ RRRRR}
< H2 > development materialsdigital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English and the alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency
according to the announcement on preventing the financing risks of token issuance jointly issued by the central bank and other seven ministries and commissions, the announcement points out that any so-called token financing trading platform shall not engage in the exchange business between legal tender and token and "virtual currency", and shall not buy or sell tokens or "virtual currency" as a central counter party, It is not allowed to provide pricing, information intermediary and other services for token or "virtual currency"
the announcement points out that token issuance financing refers to the so-called "virtual currency" raised from investors through the illegal sale and circulation of tokens. In essence, it is an unauthorized illegal public financing behavior, suspected of illegal sale of token bills, illegal issuance of securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal criminal activities<

the central bank said that the so-called "digital currency" in the market is not legal digital currency:
the central bank's gold and silver 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 used the name of the central bank and labeled relevant digital procts as "authorized issuance of the people's Bank of China", Or they falsely claim that the central bank's digital currency promotion team is trying to deceive the public and 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

In recent years, a series of policies and measures have been implemented to rece the cost and increase the efficiency of logistics, and remarkable results have been achieved. From 2013 to 2020, the ratio of total social logistics cost to GDP shows a downward trend. From January to September 2020, the ratio of total social logistics cost to GDP in China will drop to 14.4%, which has made a positive contribution to improving the development environment of the real economy and enhancing the operation efficiency of the national economy
however, behind the rapid development of the instry, there are still many problems to be solved, including commodity authenticity, logistics data island (data isolation leads to high interaction cost between enterprises, low efficiency of process collaboration), logistics credit rating (no standard, difficult financing), etc
blockchain technology helps the transformation and upgrading of logistics finance
through blockchain technology, we believe that the pain points of relevant instries can be continuously improved and optimized. For example, it involves commodity traceability, multi-agent collaboration, credit reference, supply chain finance, etc., and integrates "business flow, information flow, capital flow, and logistics". The logistics instry has become an important deployment of the logistics instry
for the future integration development direction, enterprises can combine logistics technology process optimization, logistics package traceability, financial application scenarios based on logistics and supply chain, supply chain and logistics related credit reference needs, rely on blockchain technology and existing logistics network, truly and reliably record and transmit capital flow, logistics and information flow, Optimize the utilization of resources, improve the overall efficiency of the instry, and promote the sustainable development of the logistics instry
through the combination of blockchain and logistics finance application scenarios, in essence, it is through mortgage property and data cross node sharing, and finally, it is to achieve logistics credit rating, so as to obtain financing convenience and interest rate level close to that of large institutions
with the implementation of new digital infrastructure technology represented by 5g, blockchain technology will be combined with AI, Internet of things, cloud computing and other cutting-edge technologies, enabling the construction of economic fields including logistics and other real instries
through the blockchain network, we can change the traditional management and service mode, promote department collaboration and business process optimization, rece communication and information costs, and improve management efficiency. The four major applications in the direction of process optimization, logistics tracking, logistics finance and logistics credit will be graally implemented in the fields of e-commerce logistics, shipping logistics, special logistics and logistics finance

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
first check the local public key:
$CD - /. SSH
if you prompt: no such file or directory, it means that you are using git for the first time. If it is not the first time to use it, please perform the following operation to clean up the original SSH key< br />$ mkdir key_ backup$ cp id_ rsa* key_ backup$ rm id_ RSA *
generate a new key:
$SSH keygen - t RSA - C "your email address"
in the carriage return, you will be prompted to enter a password, which will be used when you submit the project. If it is empty, you do not need to enter it when you submit the project
you can find one in your user folder under your local system disk. SSH file, where the ID_ The SSH key just generated is stored in the rsa.pub file
2. Add public key
log in to the code platform, enter the user's "account settings", click "SSH public key management" in the right column, click "add public key", fill in the newly generated public key in the "public key" column, give it a name, and save it
note: when ing the public key, do not the extra spaces, otherwise it may not be added successfully
I came across a project: sometimes, it needs to be generated by you. Under SSH directory, create a new config file and write user XXX
3. Manage public key
you can also delete or modify the public key in "account settings" - SSH public key management.
