Virtual currency without professional assets
Encrypted digital assets: encrypted digital currency is not issued by legal tender institutions and is not controlled by the central bank. It is based on the open source code of a group of equations calculated by computers all over the world. It is generated by a large number of operations of computer graphics card and CPU, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The design based on cryptography can make the cryptocurrency only be owned by real users
encrypted digital asset is also a kind of gold existing in the network world, which is a kind of encrypted digital currency based on the block chain technology and using the digital encryption principle. In a sense, it has the same circulation function as ordinary currency. Encrypted digital assets apply blockchain technology to the global financial field, which makes consumers all over the world make business investment through encrypted digital assets, and create a new business model of win-win between investors and users, which is a trend for development
virtual currency (enterprise currency) is self issued by companies or private indivials. It can be issued indefinitely, and it does not need to be obtained by solving the equation through the CPU program of computer graphics card. Because it can be issued unlimited according to the market demand, it does not have the value of collection and appreciation. There is no ore pool website, no original code. Price can be manipulated, mostly one-way relationship
in a word, virtual currency represented by bitcoin is legal in China, but the government takes a cold attitude towards virtual currency, which is neither positive nor negative. Most of the major countries in the world also adopt a cold attitude towards virtual currency
since 2015, the popular virtual currencies are bitcoin, Laite coin, Fuyuan coin, doggy coin, reborn coin and so on
it is possible, but at present, the government has not banned it
bitcoin and other virtual currencies exist legally in China. In the 2013 bitcoin risk notice, the central bank and other five ministries and commissions clearly defined bitcoin as a special Internet commodity. People can buy and sell it freely at their own risk. Financial institutions do not have to provide bitcoin related services, denying its monetary attribute. Zhou Xiaochuan, the governor of the central bank, compares bitcoin to a tradable asset like a stamp< Most of the major countries in the world take a cold attitude towards virtual currency. There are several possibilities for countries to ban virtual currency:
1
2. The well-known weaknesses and defects of virtual currency can not be overcome in a certain period of time
3. The government can't stand the use of virtual currency in money laundering and other illegal activities
since 2013, the popular virtual currencies are bitcoin, Fuyuan coin, Laite coin, doggy coin, Ruibo coin, Yuanbao coin and so on<
Zhou Xiaochuan, governor of the central bank, said at the Boao Forum for Asia that virtual currency is not a currency approved by the central bank and can not be banned. Since digital currency is not the currency initiated and approved by the central bank, it can not be banned. Digital currency belongs to digital assets, which can be freely traded between indivials. Therefore, digital currency is not MLM, not capital disk, but a kind of financial investment
in fact, the central bank has been studying digital currency for a long time. From the perspective of historical development trend, money has always evolved with the development of technological progress and economic activities. From the early physical money, commodity money to the later credit money, it is a natural choice to adapt to the development of human commercial society. As the currency of the previous generation, paper money has low technology content. From the perspective of safety and cost, it is the general trend to be replaced by new technology and new procts. In particular, with the development of the Internet and the great changes in payment methods all over the world, the establishment of digital currency issuance and circulation system is very necessary for the construction of financial infrastructure and the promotion of economic quality, efficiency and upgrading

different from sovereign currency, the "credit" basis of "virtual currency" is mathematical algorithm, and its price depends on the reliability of the algorithm, market confidence and other factors. There are many defects and loopholes in technology, and its value foundation is very fragile
the China Internet Finance Association recently announced that bitcoin and other so-called "virtual currencies" lack a clear value basis, the market has a strong speculative atmosphere, the price fluctuates violently, and investors blindly follow suit, which is easy to cause capital losses. There is no legal basis for the establishment of various so-called "currency" trading platforms in China
extended information:
in recent years, the price of bitcoin has risen rapidly, attracting a large number of people to enter. A large number of "virtual currencies" followed suit. In 2017, the price of Leyte increased by 476%, the price of Ruibo increased by 54 times, and the price of ether increased by 13 times
Li Aijun, Dean of the Internet Finance and Law Research Institute of China University of political science and law, believes that virtual currency is the proct of networking, and the digital information flowing in the network is beyond everyone's control. The code of cyberspace is the basis of the operation of virtual currency, investors can only operate through the front-end interface, seemingly "control" the virtual currency. The operator of the virtual currency service organization may become the actual controller of the virtual currency through the control code

Du Yan believes that the existence of bitcoin and exchanges and other instrial chains has constructed an illegal financial market for asset transfer and financing beyond legal tender, increased the difficulty of regulatory authorities in managing financial security and stability, and promoted regulatory arbitrage and financial crimes. The risks and social security risks it brings to the financial market are far higher than its innovative value
investors should stick to rational investment, not blindly follow the trend, nor take chances. There are risks in investment, especially in the face of a new model, we should be more cautious in investment, so as not to become the target of wealth plunder by criminals
Background: the financial application of blockchain technology brings high investment value
2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles
1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:
in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost
2. Why can blockchain solve the above pain points:
blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs
3. The application of blockchain technology in the financial field mainly includes the following aspects:
① digital currency
among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits
Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost③ digital bills
④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost
The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points
in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it
Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall) In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreementbitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain
based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network
2. Master node network
the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan

Bitcoin, English name bitcoin, is a digital currency based on blockchain technology, which is composed of a series of computer-generated complex codes. Like RMB's ￥ and US dollar's $, bitcoin has its own symbol, the "B" in the figure below
The inventor of
bitcoin is Nakamoto. Satoshi Nakamoto is the creator of bitcoin protocol and its related software bitcoin QT. In 2008, he published a paper called "bitcoin: a peer-to-peer electronic cash system", describing an electronic currency and its algorithm that he called "bitcoin"
In 2009, he released the first bitcoin software and officially launched the bitcoin financial system In 2010, he graally faded out and handed over the project to other members of the bitcoin communityNakamoto is believed to hold about one million bitcoins. If the price of each bitcoin was $2W, it was worth $20 billion at one time. So far, his true identity is still unknown to the outside world, that is to say, no one knows who Nakamoto is
bitcoin appeared after the global financial crisis in 2008. In fact, before that, many people have tried electronic currency, digital currency and virtual currency, but they have not succeeded. There are not only technical reasons, but also social environment and economic background reasons. To some extent, it was the 2008 financial crisis that gave birth to bitcoin
Bitcoin is an Internet virtual asset
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions
and use the design of cryptography to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
the design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
extended data:
currency features:
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
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform Mining: users can explore the computing power of different hardware on many platforms
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
the well-known virtual currencies are bitcoin, lightcoin, Ruitai coin, Ethereum and so on.
