Which country is ccoin virtual currency
Some virtual currencies are illegal in China. Chinese laws prohibit virtual currencies. The only legal currency in China is RMB. Since the people's Republic of China issued RMB, it has lasted 71 years. With the development of economic construction and the needs of people's life, it has graally improved and improved. So far, it has issued five sets of RMB, forming a multi variety and multi series monetary system of paper money and metal money, ordinary commemorative money and precious metal commemorative money
except for 1,2,5 fen coins, the first, second and third sets of RMB have been withdrawn from circulation, and the fourth set of RMB has been suspended from circulation since May 1, 2018 (except 1 jiao, 5 jiao notes and 5 jiao, 1 yuan coins). The current circulation of RMB is mainly the fifth set of RMB issued in 1999
the people's Bank of China is scheled to issue the fifth set of RMB 50 yuan, 20 yuan, 10 yuan, 1 yuan banknotes and 1 yuan, 5 jiao, 1 jiao coins of the 2019 edition from August 30, 2019. The fifth set of RMB inherits the traditional experience of China's printing technology and draws lessons from the advanced technology of foreign banknote design, which has greatly improved its anti-counterfeiting performance and currency processing modernization
Chairman Mao Zedong's head portrait in the early days of the founding of the people's Republic of China is used on the front of each denomination currency, the famous Chinese flower pattern is used on the bottom, and the main scenery pattern on the back fully shows China's long history and magnificent mountains and rivers, and carries forward China's great national culture by selecting representative patterns with national characteristics
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.
when it comes to virtual currency, many people may be familiar with it. But there are also many people who are not clear about the concept of virtual currency. They will think that sina u, Netease popo and Shanda Yuanbao are all part of virtual currency. What's more, they think that these so-called virtual currencies will affect the status of RMB and proce adverse effects such as virtual inflation
first of all, let's understand the two meanings of virtual currency in economics
the prototype of the first virtual currency is composed of the weights of the currencies of a country's major trading partners, which is a non-existent currency in order to maintain the stability of the country's exchange rate.
it is reported that the Ecuadorian government will soon adopt digital currency as a supplement to its dollar based real currency system
the Ecuadorian government is going to adopt digital currency instead of popular bitcoin. In fact, Ecuador will implement its own electronic currency system, officially known as "sistema de dinero electric" ó "Nico", Ecuadorian officials said that the digital currency is only a supplement to Ecuador's real currency, but some experts seem to think that there may be other motives for this move
Ecuador is not the only country to use digital currency. Sweden is also using digital currency, but the difference is that Ecuador's digital currency is run by the government itself, which can't help raising doubts. Of course, Ecuadorian officials guarantee that Ecuador's financial system will maintain the status quo, and e-money will only supplement the existing monetary system
since 2013, the popular virtual currencies are bitcoin, Fuyuan coin, Laite coin, doggy coin, Ruibo coin, Yuanbao coin and so on.
