Jingdousuan virtual currency
in the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, etc., which can be used to buy Herbs and equipment, but only in his own game console; The special currency issued by the portal website or instant messaging service provider is used to purchase the services within the website
there are four types of virtual currency in the market:
1. Game currency developed by game operators for players to use as a trading medium in online games
2. A special virtual currency issued by the portal or instant messaging tools for use in the operating cyberspace
3. Interactive virtual currency, which can be used in the issuing entity of virtual currency and can purchase goods and services from non issuing entities
4. Based on cryptography and modern network P2P technology, a special electronic and digital network cryptocurrency is proced through complex mathematical algorithm
the instrialization of virtual money will form a virtual money market. If the emergence of the stock market is the proct of the combination of instrial capital and financial capital, then virtual currency will be the proct of the combination of service capital and financial capital. Modern service instry, especially personalized modern information service instry, will become the instrial foundation of personalized virtual currency
the personalized virtual money market is different from the stock market and derivative financial instrument market. The latter is more established for the needs of instrialization, which is also reflected in meeting the needs of the so-called modern service instry; The instrial foundation of the former is closely related to the demand of informatization
The future of the tertiary instry is different from the service instry, its development direction is the post-modern service instry, that is, the experience instry, that is, more personalized instry to meet the development needs of spirit, culture and entertainment. The stock market will make more use of information to guide the rational investment of instry and service instry, while the personalized virtual money market will make more use of information to guide the perceptual consumption of experience instryVirtual 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
reference: network virtual currency
100 Jingdou is equivalent to 1 yuan. Jingdou can be directly used to pay for Jingdong website orders (except for investment gold and silver, collectibles and some virtual procts that do not support Jingdou payment). The proportion of Jingdou and cash dection is 100:1. Jingdou payment shall not exceed 50% of the settlement amount of each order. The number of Jingdou can be an integral multiple of 1000, such as 1000, 2000, 3000, etc
if the settlement amount is 100 yuan and 50% is 50 yuan, the settlement can only be paid with 5000 Jingdou at most; If the number of Jingdou is less than 1000, Jingdou payment cannot be used on the settlement page or at the cashier
extended data:
the feedback quantity of Jingdou is calculated according to the category of the commodity when the user completes the order and a certain proportion of the actual payment value of the commodity, and only the integer is counted
when the goods belong to the four categories of computer / office, household appliances, mobile phone and digital, the amount of Jingdou's feedback is 5% of the actual amount paid. For example, the user will enjoy the feedback of two Jingdou's when he pays 50 yuan; When the goods belong to other categories, the amount of Jingdou returned is 10% of the actual amount paid. For example, the user who paid 50 yuan will enjoy the return of 5 Jingdou< strong>
digital currency has made great progress in China, and the central bank version of digital currency has come out, which will first be applied to the bill market. The domestic Puyin group has launched the tea based digital currency Puyin, which has the credit endorsement of tea assets.
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.
however, it can only be used with 1000 beans.
