The development history of virtual currency

When the global financial crisis broke out in 2008, someone published a paper under the pseudonym of "Nakamoto Tsung", describing the mode of bitcoin

many bitcoin players are attracted by the fact that bitcoin can not be issued at will. Contrary to the attitude of bitcoin players, economists have a polarized attitude towards the fixed amount of 21 million bitcoin

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer

when bitcoin was born in 2009, each reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the bounty will be halved to 25. When the total amount reached 15.75 million (5.25 million new output, or 50% of 1050), the bounty was further halved to 12.5

first of all, according to its design principle, the total amount of bitcoin will continue to grow until it reaches 21 million more than 100 years later. But the total amount of bitcoin will grow very slowly in the later period. In fact, 87.5% of bitcoin will be "g up" in the first 12 years. Therefore, in terms of the total amount of money, bitcoin will not reach a fixed amount, and its total amount of money will continue to expand, although the speed is getting slower and slower. So it looks like bitcoin is the inflation currency

bitcoin is a kind of network virtual currency with limited quantity, but it can be used to cash out: it can be converted into the currency of most countries. You can use bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items

The main background of net currency is the difficulty of domestic micro electronic payment. Online game operators use this channel is not cheap vouchers to charge fees. Originally, only RMB was allowed to be exchanged for net currency, but reverse exchange was not allowed. However, with the development of online game instry, people spontaneously exchange various kinds of online currency, and even use online currency to buy physical procts or services that only RMB can buy, forming a purchasing power similar to currency. The boundary between virtual currency and real currency is graally blurred
in fact, in countries with developed financial environment, virtual currency has appeared for a long time, and its purpose is to make profits. For example, the virtual currency "Wangdou" first introced by beenz. Beenz has reached an agreement with MasterCard that consumers can not only save their online beans into smart cards, but also use them in traditional stores. This business model is to sell virtual net beans to some websites for 1 cent each, and then send them to netizens or let them win through various ways. These virtual currencies can be consumed as cash in online stores. In the end, beenz will buy it back from the website operator for 0.5 cents each for a profit. In 2000, there were about 750 million beenz beans in circulation, equivalent to 60 or 70 million yuan. It was also at that time that China's online currency appeared. China bonus provided virtual currency to consumers in the form of points. Points accumulated to a certain amount, can be used to exchange phone cards, network cards, T-shirts and other prizes
in online games, virtual goods such as virtual gold coins, virtual equipment, virtual animals and plants, and virtual people have great attraction for players, which promotes the consumption of these virtual goods. However, e to the backwardness of domestic electronic payment methods and security concerns, players often use cash in advance to buy the virtual currency issued by operators, Then use these vouchers to buy virtual goods online. As long as the content of the game is attractive enough, players will buy the virtual currency issued by the game operator through various channels. The development of online game instry has led to the surge of virtual currency types and circulation
in order to gather popularity, expand the number of game users, and improve the interest and loyalty of players, all game operators provide a considerable amount of free virtual currency, and players can win virtual currency through the game process. Therefore, online game operators actually have unlimited rights to issue virtual currency. If virtual money is only used to buy virtual goods, because the supply of virtual goods is artificially set, and the manufacturing time can be almost ignored, even if there are transactions between different types of virtual money, it will not have any impact on the real economy. However, if virtual currency can be used to buy real goods and services, excessive issuance will certainly cause inflation. At this time, whether the virtual currency is converted into real currency is not important
many domestic network enterprises have broken through the boundary between the virtual economy and the real economy. For example, Netease popo rewards users with money according to their online time. This virtual currency can pay for SMS. The exchange rate in this application can be calculated with the payment capacity of a short message worth 1000 yuan equal to 0.4 yuan; In addition, it can also be used as a voucher for purchasing physical goods in Netease mall. Holders of Shanda point coin can buy paid download services on the Internet. In addition to the company's paid services, q-coin can also be used to purchase other game point cards, virtual goods, and even some video and software download services
the emergence of money is an abstract unit of quantity for the convenience of exchanging different resources. If there are enough people to recognize the value of a virtual currency, it may become a substitute unit of material exchange. For example, with the popularity of QQ, Q coin has graally become a circulating equivalent exchange unit. Adam Smith, a famous economist, used barter to explain the origin of money in 1776: "the armor of Diomedes is only worth 9 cows, while the armor of glaucus is worth 100 cows. In Abyssinia, salt is a common medium of Commerce and trade; More than 200 years later, many people are exchanging various kinds of game currency for real life needs, and the Internet world has begun to dece the origin of currency again

The essence of money is the general equivalent. In the process of the continuous development and evolution of human history, it has gone through the stage of physical money, the stage of substitute money, and then entered the stage of credit money. In primitive society, people exchanged livestock, salt, shells and other hard to get goods as general equivalents

in the long history, the emergence of metal currency makes the economic life achieve unprecedented prosperity. However, e to the inconvenience of carrying metal money, paper money became the mainstream form of money. With the rapid development of modern information technology, e-money has come into our life

if the evolution process from physical money to value symbol paper money is the first qualitative leap in the history of money development, then the evolution process from paper money to electronic money is the second qualitative leap in the history of money development

from the perspective of money form, physical money itself is a commodity in addition to performing monetary functions; Paper money is a symbolic tool of value for commodity exchange and a credit currency; Electronic currency is the proct of highly developed Internet economy and continuous progress of bank payment and settlement technology. It not only has the function of traditional currency, but also can continuously improve digital currency

a huge virtual space based on the Internet has been formally formed. As a kind of virtual currency with intrinsic value, convenient online trading behavior, low transaction cost, and service providers' issuance, it emerges as the times require

first of all, from the functional analysis. Virtual currency is a kind of transaction medium in the Internet virtual space, which has the function of value scale, but the value scale of virtual currency is different from that of legal currency

using virtual currency to purchase virtual procts and services can only be within the scope specified and allowed by the issuer of virtual currency (Internet operator), and the size of this scope depends on the number of virtual procts and services. If the virtual procts and services provided by the website are large enough, the scope of virtual currency will be large

the currency value of virtual currency depends on the pricing of virtual currency by issuers. When no currency can communicate between virtual cyberspace and reality, the pricing of procts and services is still based on real RMB. That is to say, when issuers of virtual currency price their own virtual currency, they should first convert the price of virtual currency based on RMB

Method 1: take a look at the display interface. Most of the display interfaces of the mine cards are not consistent with their own quality, because the display interface is basically not used in mining, so if all the display interfaces are very new, even the plastic plug is on them, you should pay a little attention to them

extended data:

1. Graphics card and mine card:

the so-called mine card is the graphics card for mining. The "mining" here is virtual mining. Generally, there are professional graphics cards to mine. The mined mine is actually bitcoin. Users can download the mining software from the computer, run a specific algorithm, and get the corresponding bitcoin after communicating with the remote server, Most of them work in the way of burning video card, so the power consumption is large

the graphics cards and mine cards are usually ATI chips. Bitcoin went out of business, and the miners took out their mining cards and sold them as second-hand

2. Disadvantages of mine card:

Mining mostly adopts the way of burning graphics card. In order to maximize the benefits, the mine owners will keep the graphics card in 24-hour full load operation, which is equivalent to the aging test all the time, so that the graphics card can quickly age. After a long time of mining, the stability and life of the graphics card will certainly be affected< br />
