Types and characteristics of virtual currency

1. digital currency has a wide range of transactions, virtual currency is small, knowledge is limited, language expression ability is general, but we have tried our best to answer, hope the answer can help you!

2. In addition to bitcoin, there are many other virtual currencies in the virtual world< Liteoin (LTC) was released on October 7, 2011, and is currently the most valuable counterfeit currency, accounting for about 2% of BTC's market value. The current unit price is US $2.31, with a total currency value of US $38 million

this is also a distributed (decentralized) digital currency. Unlike the sha256 mining algorithm used by bitcoin, LTC adopts scrypt algorithm. Scrypt algorithm uses sha256 as its subroutine, and scrypt itself needs a lot of memory. Each hash is used as the seed of the input, and then it needs a lot of memory to store another pseudo-random sequence to generate the pseudo-random points of the sequence and output the hash value. In the mining of BTC (bitcoin), it is not enough to rely on simple graphics card mining (it takes about ten to dozens of days to dig a BTC with general configuration graphics card). The emergence of various expensive mining machines has raised the threshold for ordinary people to get BTC through mining, while LTC has certain advantages in using PC graphics card mining This passage comes from Zhihu.)

compared with BTC, litecain has made a little improvement in technology. If BTC is gold now, LTC is silver for the time being

the biggest advantage of litecoin is that it can confirm the authenticity faster. The virtual currency is designed and maintained by Charles Lee. Bitcoin transactions need to be verified, and the average verification time is more than 10 minutes. Most transaction websites need 1 hour to verify. The average transaction confirmation time of liteoin is 2.5 minutes. Developers claim that shortening the verification time increases the practicability of virtual currency. The bitcoin mining efficiency of customized machine and AMD GPU is the highest, making it almost unprofitable for miners using CPU mining. Litecain's mining excludes GPUs and custom processors, so it doesn't rely too much on a small number of professional miners

ppcoin

ppcoin (PPC) was released on August 19, 2012, which has improved the original technology of BTC. Use proof of make and add the concept of coin age

ppcoin is a bifurcated project of bitcoin, which aims to achieve energy efficiency and maintain the best performance of the original bitcoin as far as possible. The unit price of ppcoin is US $0.22 and the total currency value is US $4 million

ppcoin does not have a fixed upper limit of money supply, but it does not mean that ppcoin has obvious inflation compared with bitcoin. Bitcoin can be compared to gold. The annual inflation rate of gold is about 1-3%. Although gold has no known upper limit of money supply, we still know that it is a reliable scarce commodity

ppcoin has two types of casting: work certificate and equity certificate. The coinage rate of working proof is affected by Moore's law, which depends on the doubling of our working proof ability. What we all know is that Moore's law will eventually come to an end. By then, the ppcoin of inflation may be close to the gold level. The annual maximum inflation rate of certificate of equity is 1%. At the same time, ppcoin's transaction costs were destroyed to fight inflation. So on the whole, the coin design of ppcoin is still a very low inflation design in the future, which can be comparable with bitcoin<

ppcoin's reward is similar to lottery, which will determine the winning probability according to the number of ppcoin held by miners. Sunny king, one of the founders, said that their design is based on a new concept of long-term energy efficiency

terracoin

terracoin (TRC) was released on October 26, 2012, with a total currency of 42 million. The speed of each block is 2 minutes, slightly faster than LTC. There is not much special in technology, similar to the proction of BTC halved every four years

however, the operation team seems to have a strong business background and may be better than other bitcoins in circulation. The development of virtual currency is getting more and more attention. Now some teams with business background will accelerate the development of virtual currency

namecoin

namecoin is a distributed domain name system based on bitcoin technology. Its principle is the same as bitcoin. The first release date of this open source software is April 18, 2011

namecoin is generated from an original block which is different from bitcoin's main trading block. It uses a new blockchain, which is independent of bitcoin's blockchain. Because it is based on bitcoin, the security, distribution, robustness, encryption and migration of domain names are guaranteed mathematically. You can dig bitcoin and namecoin at the same time

this project was discussed and proposed by bitdns, which is mainly dissatisfied with the defects of DNS. The only top-level domain name of namecoin is. Bit. It costs namecoin to register a. Bit domain name

in addition, Q currency, Shanda currency, starting point currency and various online game currencies are also virtual currencies.

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

4. 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

1. The essence of interpretation is different:

virtual currency: virtual currency refers to non real currency

currency: currency (CCY) is the medium of purchasing goods and preserving wealth. It is the contract between the owner of property and the market about the right of exchange. In essence, it is the agreement between the owners

2. Different types:

virtual currency: game currency, special currency, etc.

currency: coin, paper currency, deposit currency, etc.

extended data:

formation of virtual currency market:

Internet leads to the emergence of a new market, which is a virtual market based on cyberspace. The Internet provides a lot of communication places for consumers, and also provides business market for enterprises. Enterprises must change from proct centered to service centered to customer centered

with the development of computer artificial intelligence technology and database technology, enterprises can conveniently collect customers' information, understand customers' needs in time, change business strategies and grasp economic arteries in real time

6. Virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent company's Q currency, Q point, Shanda company's voucher; The popular digital currencies in 2013 include bitcoin, Leyte coin, Fuyuan coin, doggy coin and so on
network virtual currency can be roughly divided into

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 using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", 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 kind of virtual currency on the Internet, such as bitcoin (BTC), Fuyuan coin (FTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency.

7. At the moment, there is a big difference. I feel that the most common point is that all of them can be used for payment. For example, Dell accepts bitcoin payment to buy computers. Or you can ask Babbitt, where there are more cattle.

8. This may be caused by a variety of reasons. First of all, as far as I know, Mt. GOx (commonly known as Mentougou), the world's largest bitcoin trading platform at that time, announced before February 10 that the withdrawal of bitcoin had been suspended e to technical problems, and planned to solve the technical problems and resume bitcoin on February 10. However, on February 10, bitcoin did not recover, and the problem of address forking of bitcoin wallet broke out, claiming that it was not only his own problem, but the same problem existed in the whole bitcoin system, which affected the price of bitcoin plummeting for the first time. The Mentougou incident cast a shadow on bitcoin and once plummeted below 2000

however, this has something to do with the wantonly one-sided reports of the media, which has caused excessive panic among bitcoin players and made selling bitcoin popular

the bitcoin mining machine instry is also deeply affected by this incident. At this stage, bitcoin miners are mining at a loss, and the mining machines in the market are also ignored. Take the mainstream Avalon chip in the market as an example. As the price of bitcoin continues to fall, the price of the third generation Avalon chip has been reced from 80 yuan to 14 yuan since it was released. However, with the recovery of bitcoin price, the sales of bitcoin mining machines are booming again.

CPU support type: 7th / 6th generation Core i7 / i5 / I3 / Pentium / Celeron

CPU slot: LGA 1151

CPU Description: supports Intel 14nm processor

extended data:

the main board is divided into chipsets. According to the structural characteristics of the main board, it can also be divided into CPU based main board, adapter circuit based main board, integrated main board, etc. The integrated motherboard based on CPU is a better choice

chipset is the core of motherboard circuit. In a sense, it determines the level and grade of the motherboard. It is & quot; Nanqiao & quot; And & quot; North Bridge & quot; The general name of the chip group is to integrate the complex circuits and components in several chips to the maximum extent. Intel Chipset is specially designed for Intel processor, which is used to connect CPU with other devices such as memory, graphics card, etc

the north bridge chip is mainly responsible for data transmission with CPU, memory and AGP interfaces, and it is also connected with the south bridge chip through specific data channels. The packaging mode of Beiqiao chip initially uses BGA packaging mode, and Intel's Beiqiao chip has been transformed into FC-PGA packaging mode. However, the motherboard Beiqiao chip designed for AMD processor still uses the traditional BGA packaging mode
