Virtual currency is the currency used for electronic circulation. Now the scope of virtual currency is very large, including q-coin, bitcoin and so on. With the development of digital currency, virtual currency is becoming more and more abundant, which may become the mainstream in the future. For example, BTC, EOS, bcbot and so on are not only virtual currencies, but also algorithms, landing projects and technologies

virtual currency is mainly issued by online game service providers to purchase game props, such as equipment, clothing, etc. But at present, the use of virtual currency has gone far beyond this category. Virtual currency can be used to buy game cards, physical objects and download services of some movies and software

extended data:

real risk

as the proct of e-commerce, virtual currency has begun to play an increasingly important role, and it is more and more connected with the real world. However, with the growth of virtual currency, the relevant laws and regulations are lagging behind, which has laid many hidden dangers

fraud

the private transaction of online virtual currency has realized the two-way circulation between virtual currency and RMB to a certain extent. The activity of these traders is to buy all kinds of virtual currencies and procts at a low price, and then sell them at a high price to earn profits. With the increase of such transactions, there are even virtual mints. In addition to the virtual currency provided by the main company, there are also some people who specialize in "virtual coin making" to obtain virtual currency by playing games and then resell it to other players

Taking Wenzhou as an example, there are about seven or eight such "virtual mints" with four or five hundred practitioners. This not only creates a bubble for the price of the virtual currency itself, but also causes trouble for the normal sale of the issuing company. It also provides a platform for selling and collecting money and money laundering for various cyber crimes. p>

impact system

in modern financial system, the issuers of money are generally central banks, which are responsible for the management and supervision of money operation. As the equivalent exchange goods used to replace the real currency circulation on the Internet, the virtual currency on the Internet is essentially the same as the real currency. The difference is that the issuers are no longer central banks, but Internet companies

if the development of virtual currency makes it form a unified market, each company can exchange with each other, or virtual currency is integrated and unified, and all of them are based on the same standard and price, then in a sense, virtual currency is currency, which is likely to form a threat impact on the traditional financial system or economic operation

4. Litecoin

litecoin (LTC), released on October 7, 2011, is the most valuable counterfeit coin at present, 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.

5. Virtual currency refers to the currency that does not exist in reality and exists in a virtual state, such as bitcoin, lightcoin, Ethereum and so on; Token refers to the form of money that can be used as a monetary function and can be used to purchase goods

According to the definition of the European Central Bank in 2012, "a kind of digital currency that is not legally binding, issued and controlled by developers, and accepted and used in specific virtual community members."

at the 2013 congressional hearing, Federal Reserve Chairman Ben Bernanke said that "in the past two decades, virtual currency has been regarded as an electronic currency, or a payment system technology field that has been developing."< In 2013, the financial crime enforcement network (FinCEN) of the U.S. Department of the Treasury defined it as: "virtual currency is a medium of exchange that operates like real currency in some environments, but it does not have all the attributes of real currency." It also has no legal tender status. In 2014, the European Banking authority defined it as "a digital form of value that is not issued by central banks or government departments and is not necessarily associated with legal tender, but it is accepted by natural and legal persons as a means of payment and can be transferred, stored and traded electronically

in Chinese mainland refers to the currency that runs on the Internet, and the famous virtual currency, such as Tencent Inc's Q coins and the grand company's roll, also has virtual currency in online games. Virtual currency is usually used for users to purchase virtual services on the network, such as QQ membership function of Tencent's QQ coin, online game equipment, etc. Virtual currency is usually a means of payment. For example, the Ministry of culture of the people's Republic of China defined it in 2009 as a virtual exchange tool that is issued by online game operators, directly or indirectly purchased by game users using legal tender in a certain proportion, existing outside game programs, stored in servers provided by online game operators in the form of electromagnetic records, and expressed in specific digital units
