Virtual currency obtained by algorithm

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.

There is no official recognition of any virtual currency in China

different from sovereign currency, the "credit" basis of "virtual currency" is mathematical algorithm, and its price depends on the reliability of the algorithm, market confidence and other factors. There are many defects and loopholes in technology, and its value foundation is very fragile

the China Internet Finance Association recently announced that bitcoin and other so-called "virtual currencies" lack a clear value basis, the market has a strong speculative atmosphere, the price fluctuates violently, and investors blindly follow suit, which is easy to cause capital losses. There is no legal basis for the establishment of various so-called "currency" trading platforms in China

extended information:

in recent years, the price of bitcoin has risen rapidly, attracting a large number of people to enter. A large number of "virtual currencies" followed suit. In 2017, the price of Leyte increased by 476%, the price of Ruibo increased by 54 times, and the price of ether increased by 13 times

Li Aijun, Dean of the Internet Finance and Law Research Institute of China University of political science and law, believes that virtual currency is the proct of networking, 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

Du Yan believes that the existence of bitcoin and exchanges and other instrial chains has constructed an illegal financial market for asset transfer and financing beyond legal tender, 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

investors should stick to rational investment, not blindly follow the trend, nor take chances. There are risks in investment, especially in the face of a new model, we should be more cautious in investment, so as not to become the target of wealth plunder by criminals

Ppcoinppcoin (PPC) was released on August 19, 2012, which has improved the original technology of BTC. Use proof of stack and join the concept of coinage. Ppcoin is a bifurcated project of bitcoin, which aims to achieve energy efficiency and keep 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.

6. Bitcoin is different from q-coin. Tencent can sell q-coin at will. The total amount of bitcoin is limited. The total amount of bitcoin graally increases according to the designed rate, and the increase rate graally slows down, and finally reaches the limit of 21 million in 2140. No one can control it alone. It comes from the program algorithm, cryptography and other network technology, with open equivalence, consensus initiative, unlike paper money can be manipulated and indiscriminately issued. Because of this, bitcoin security, anti inflation and security.

7. Now there are about 500 kinds of virtual currencies in the world, such as Wright's coin, Waley's coin, dog's coin, black coin and dark coin, which are so-called counterfeit currency or competitive currency. Most of them are based on bitcoin like algorithm, some of them are slightly adjusted, and generally speaking, they are not innovative. In the process of mutual competition and elimination, one or two or even several of these virtual currencies may rise to become the second virtual currency. But in terms of public acceptance and total currency value, bitcoin is still hard to be expected. After all, bitcoin is the originator of virtual currency. Everything else is a replica, just like the relationship between Coca Cola and Pepsi Cola, very cola and so on. Therefore, the author thinks that in the current framework of several algorithms, the probability of competitive currency replacing bitcoin is very small

8. In short, there are three ways:

9. Virtual currency, which is often called digital currency, is generated by the algorithm of computer software. At present, the most famous is bitcoin. Then there is our digital RMB. In fact, according to different algorithms, in theory, there can be countless kinds of digital currency. The specific number of issues depends on the will of the issuing body.
