Virtual currency issue and virtual currency transaction

4. In fact, it is the proction process and method of virtual currency, in short, it is mining. Let's take bitcoin as an example to show that more people can go to bitcoin home and

anyone can run software on special hardware to become a bitcoin miner. Mining software monitors transaction broadcast through P2P network and performs appropriate tasks to process and confirm these transactions. Bitcoin miners can earn transaction fees paid by users to speed up transaction processing and additional bitcoin issued according to fixed formula
new transactions need to be included in a block with mathematical workload proof before they can be confirmed. This kind of proof is hard to generate because it can only be generated by trying billions of calculations per second. Miners need to run these calculations before their blocks are accepted and rewarded. As more people start mining, the difficulty of finding effective blocks will be automatically increased by the network to ensure that the average time to find a block remains at 10 minutes. Therefore, the competition for mining is very fierce, and no indivial miner can control the content contained in the block chain
workload proof is also designed to rely on previous blocks, which forces the time sequence of block chain. This design makes it extremely difficult to cancel previous transactions, because the workload proof of all subsequent blocks needs to be recalculated. When two blocks are found at the same time, the miner will process the first block received, and once the next block is found, it will be transferred to the longest block chain. This ensures that the mining process maintains a global consistency based on processing capacity
bitcoin miners can neither increase their rewards by cheating, nor deal with the fraulent transactions that destroy the bitcoin network, because all bitcoin nodes will reject the blocks containing invalid data that violate the bitcoin protocol rules. Therefore, even if not all bitcoin miners can be trusted, the bitcoin network is still secure.

The differences between e-money and virtual money are as follows:

1. Electronic money refers to using a certain amount of cash or deposit to exchange from the issuer and obtain data representing the same amount, or through the quick payment service launched by the bank and the third party to transfer the balance in the bank through some electronic ways, so that transactions can be carried out. Strictly speaking, it is a kind of currency that consumers use the bank's Internet banking service to store value and make quick payment to the issuers of electronic currency, and make consumers trade electronically through media (two-dimensional code or hardware equipment)

Virtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"

The detailed explanation of electronic currency is as follows:

1. Concept: it is an encrypted serial number representing cash, which can be used to represent the currency value of various amounts in reality. With the transformation from paper-based economy to digital economy, e-cash will become the mainstream

2. Features: anonymity, transaction cost saving, transmission cost saving, low holding risk, flexible and convenient payment, anti-counterfeiting and anti repetition, non traceability

There are two kinds of e-cash: one is based on the Internet and keeps the binary data representing the value of money in the hard disk of the computer terminal; One is the electronic wallet that keeps the monetary value in the IC card and can be circulated without the bank payment system

4. Definition: consumers pay traditional money to the issuers of electronic money, and the issuers store the equal value of traditional money in the electronic devices held by consumers in electronic form

6. With the development of the Internet, while providing a large number of free services to the majority of Internet users, according to the company's profit needs and the diversified needs of users, various websites have launched charging services. This also promoted the emergence of virtual currency
in order to provide better services, many portal websites and online game operators have been providing virtual currency for use for a long time. According to incomplete statistics, there are no less than 10 kinds of network virtual currency (referred to as network currency) currently in circulation, such as Q currency, network currency, cool currency, Warcraft currency, Paradise currency, Shanda (game area) coupon, etc. Take Q coin as an example, there are more than 200 million users. Instry insiders estimate that the domestic Internet has a virtual money market scale of several billion yuan per year, and is growing at a rate of 15% - 20%
in a market economy, demand stimulates innovation, which in turn stimulates demand. The increasing popularity of virtual currency is completed in the needs of users and the innovation of enterprises. At present, there are many kinds of virtual currency in China's network market, among which Tencent, relying on its huge QQ users, has timely launched QQ currency with the maturity of instant messaging market
it is undeniable that virtual currency makes us feel the convenience of purchasing network services, which is the inevitable proct of the development of network economy. But at present, the network virtual currency has quietly changed into a huge trading market
Lyndon larush, a famous American economist, once predicted that from 2050, the virtual currency of the Internet will be officially recognized to some extent and become a mobile currency. With such a large market and bright prospects, many companies are eager to try and intend to occupy this market. Now it seems that the network, PayPal (PayPal) and Tencent are in the leading position
at the present stage, most e-money is based on the existing real money (cash or deposit), which has the function of "value measurement" and "value preservation", and the precondition that e-money and real money can exchange at a ratio of 1
: 1 is established
as a means of payment, most e-money can not be separated from cash or deposit. It is transmitted and transferred by electronic means to pay off creditor's rights and debts and realize settlement. Therefore, the function and influence of e-money at present is essentially the relationship between e-money, cash and deposit
at present, there are four types of popular electronic currency in China
1. Stored value card electronic currency. Generally, it appears in the form of magnetic card or IC card. Besides commercial banks, it is also issued by telecommunication departments (ordinary telephone card, IC telephone card), IC enterprises (network card), commercial retail enterprises (various consumption cards), government organs (internal consumption IC card) and schools (Campus IC card). After the issuer receives the customer's funds in advance, it issues the equivalent stored value card, which makes the stored value card a new "deposit account" independent of the bank deposit. At the same time, the stored value card in the customer consumption to dect the way to pay fees, which is equivalent to the deposit account payment currency. At present, the deposits in the stored value cards are not included in the central bank's reserve requirements. Therefore, the stored value cards can rece the demand for cash and current savings
2. Credit card applied electronic currency. It refers to the credit card or quasi credit card issued by commercial banks, credit card companies and other issuers. The loan can be consumed within the credit limit specified by the issuer, and then the repayment can be made at the specified time. The widespread use of credit cards can expand consumer credit and affect money supply
3. They are mainly debit cards, electronic checks, etc., which are used to withdraw cash, transfer settlement and transfer funds from bank deposits in an electronic way. The widespread use of this kind of electronic payment method can rece the cost of consumers to and from the bank, rece the balance of cash demand, and speed up the circulation of money
4. Cash analog electronic currency. There are mainly two kinds: one is e-cash which is based on the Internet environment and keeps the binary data representing the value of money in the hard disk of the computer terminal; One is the electronic wallet that keeps the monetary value in the IC card and can be circulated without the bank payment system. This kind of e-money has the characteristics of anonymity of cash, can be used for payment between indivials, and can change hands many times. It is developed for the purpose of replacing entity cash. The expanding use of this kind of electronic currency can affect the currency issuing mechanism, rece the seigniorage income of the central bank, and rece the scale of assets and liabilities of the central bank

7. It's not a concept. Virtual money includes electronic money
1. Network virtual currency can be roughly divided into two categories:
the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and uses these virtual game data to buy Herbs and equipment, or in some special games as a scoring unit to increase the fun of the game, which is an embodiment of the player level. But it can only be used in your own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community and the realization of game networking, there has been a "financial market" for virtual currency, where players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third category refers to bitcoin, Ruitai coin, Laite coin, Weimeng coin and other digital cryptocurrencies
2. Electronic money refers to the exchange of a certain amount of cash or deposit from the issuer and the acquisition of data representing the same amount. By using some electronic methods, the data can be directly transferred to the payment object, so as to pay off the debt.

There are two reasons for the prohibition of virtual currency trading by the state:

1. The price fluctuates violently and the consumer protection is lacking:

virtual currency is the proct of network, 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

bitcoin and other so-called "virtual currencies" lack a clear value basis, the market is full of speculative atmosphere, the price fluctuates violently, and investors blindly follow suit, which is easy to cause capital losses

2. Evade supervision and become the "accomplice" of criminal activities:

bitcoin is popular as a payment tool in the so-called "dark web" world“ The "dark net" is full of all kinds of serious criminal activities. One of the original intentions of the invention of bitcoin is to evade regulation. It has the characteristics of anonymity and convenient cross-border flow, and has become the preferred tool of "underground economy"

the existence of bitcoin and exchanges and other instrial chains has constructed a illegal financial market for asset transfer and financing in addition to legal currency, 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

extended information

virtual currency transactions are not protected by law:

according to the notice on preventing bitcoin risks issued by the people's Bank of China and other departments on December 3, 2013 and the announcement on preventing financing risks of token issuance issued by seven ministries and commissions including the people's Bank of China on September 4, 2017, virtual currency is not issued by monetary authorities, It is not a real currency because it does not have the monetary attributes of legal compensation and compulsion

in terms of nature, virtual currency should be a specific virtual commodity, which does not have the same legal status as currency, and can not and should not be used as currency in the market. Although citizens' investment and trading in other virtual currencies are personal freedom, they can not be protected by law

9. All basic information types are OK. It's very easy to find websites with blockchain information types. You can go online to "blockchain network". There are at least thousands of information stations like "blockchain XX network" in China. No, let's go online.

10. It's not a mining machine. It depends on where you put it. There are high gold mines. It's all stone
