1. 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"
according to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have legal compensation and mandatory monetary attributes, is not a real currency, does not have the same legal status as currency, cannot and should not be used as currency in the market, and citizens' investment and transaction of virtual currency are not protected by law

2. Litecoin litecoin (LTC), released on October 7, 2011, is currently the most valuable counterfeit coin, 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. It's 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, litecoin 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 amdgpu 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. 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. 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. There are two types of ppcoin 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 is awarded in a lottery like way, and the winning probability is determined by the number of ppcoins held by miners, said sunny king, one of the founders. 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 bitcoin 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. This open source software was first released on 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 mathematically guaranteed. 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.

3. Vsys public chain (token: vsys) is a blockchain database cloud created by sunny king, the father of pos. it is stored in an object-oriented way. It has the ability to support high concurrency, efficient indexing and other blockchain data usage scenarios, and can support large-scale society oriented decentralized instrial applications in the future. Its vision is to create a virtual economy era with billions of blockchain services for people to use in the future.
