Virtual currency of new technology

1. 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.

2. If a few years ago, maybe I would not hesitate to say bitcoin, but in recent years, the development of bitcoin is a bit unsatisfactory. Today's latest information report also shows that the price of bitcoin has fallen below $10000. If you only hold bitcoin, it may not be good news, but it has no effect on the virtual currency contract transaction, which can be traded in both directions
if you don't have a lot of spare money on hand, it's a good choice to invest in virtual currency at this time. With a threshold of several hundred yuan, new users of the realm can also get a $50 coupon, which will not affect our lives, but also bring considerable benefits<
the investment mode that can also trade is not only suitable for young people, but also for the elderly, because it does not require you to have much deep investment experience, as long as you know how to judge the direction of price rise and fall, and the trading time is relatively free, 24 hours a day can be operated at any time.

3. Understanding of the concept of virtual currency
(1) virtual currency based on entity
since ancient times, all "money" made of paper is called paper currency, and all countries in the world are actually paper currency. In Marx's time, paper money was only a symbol of metal money. The actual gold content of paper money was equal to the nominal gold content. When the nominal gold content was greater than the actual gold content, the price index of metal money would increase because of too many paper money. When it exceeded a certain limit, inflation would occur. Marx called these over issued bank notes without gold as guarantee virtual currency. In Keynesian era, paper money was the symbol of GDP. He defined the issue of paper money caused by making up the fiscal deficit as deficit money, and believed that the issue of paper deficit money could promote the development of proction to a certain extent, but only cause half inflation. Zhang chunjia's research in "Introction to virtual currency" also proves that paper money without precious metal and GDP guarantee will cause price rise, and this kind of money is called virtual currency
(2) virtual currency based on virtual
virtual currency is a new type of currency emerging at a certain stage of network social and economic development to meet the security and convenience needs of users. It represents the development direction of future currency existence form. It comes from the Internet, and acts as a general equivalent in the network society completely or partially. Virtual currency is a real currency with the basic attributes of currency, but it is virtual and depends on the network virtual environment. Virtual currency is born without borders, which makes it more liquid than traditional currency in the world. Virtual world corresponds to the real world. Through the exchange relationship between virtual currency and traditional currency, under certain conditions, specific virtual currency can buy physical goods, and traditional currency can also buy specific virtual goods< Second, the characteristics of virtual currency
1. Value: users get utility value by consuming the procts and services provided by operators. Virtual currency has value by providing exchange to meet the utility of consumers. The quantity of virtual currency measures the value of general goods. The issue essence of virtual currency is credit issue, which is the creditor's right of the holder to the issuer. To a certain extent, the value of this kind of claim is the right of claim
2. Virtual environment dependence. The existence of virtual currency is based on the virtual economic environment provided by the issuers and the sustainable operation of the issuers themselves. Otherwise, virtual currency has no significance.
3. Short sighted currency. As the highest price in the process of commodity exchange, the form of currency value can be regarded as the real currency. Because of the limitation of circulation scope, virtual currency can not be used as the general equivalent of all commodities; But in a certain range, it has the function of monetary value scale and circulation means. Therefore, it can be considered that virtual currency is similar to the form of money value, and it is a primary form of money, which is similar to money< The issue and circulation of virtual money is limited, but it will enlarge the money supply through the money multiplier effect, and affect the difficulty and accuracy of macroeconomic regulation and control. The issuers of virtual money need to report their circulation and circulation to the central bank, and obey the unified management of the central bank at any time
5. Virtual currency, which is issued by non-financial entities outside the financial system, aims to obtain business opportunities and competitive advantages. It is a market behavior and will inevitably lead to competition among issuers. This kind of competition will proce unfair competition behavior or obtain competitive advantage through rent-seeking, which determines the need to regulate the market behavior of the market subject according to the laws and regulations
6. Virtuality: as a kind of approximate currency, virtual currency is virtual existence if it only exists in the virtual world and can purchase the virtual property in it; If it is linked with sovereign currency, it can exist in the real world and purchase real assets, then it is a virtual thing of sovereign currency. Virtual currency is actually a series of data files existing in the computer system. It has the meaning of virtual currency only after the issuers explain the system. Therefore, the existence form of virtual currency is virtual< In general, virtual currency can purchase the procts and services provided by the issuers, and it can also be exchanged with the issuers outside the scope of issuance at a certain rate to purchase the procts of the alliance. For procts outside the alliance, virtual currency has no value significance; Similarly, when virtual currency is only authorized to buy different procts in different sales cycles, the use of virtual currency has limited application in time and scope, unlike sovereign currency, which can be completely freely exchanged
8. Separability: virtual currency has no physical form and is a digital storage information. Unlike traditional paper currency, it needs to consider the balance relationship between the circulation of main currency and subsidiary currency and the proportion of various currency values. It can be split infinitely. For example, although the total number of dark coins is only 2300, each bitcoin can be split into eight directions of ten< Although virtual currency exists in the virtual world, the process of new technological revolution has closely linked the virtual world with reality, and the virtual world has become an important part of people's spiritual life. It can promote the development of real economy, for example, a large number of entertainment application projects provide people with rich spiritual wealth and real wealth, and more and more people invest in virtual currency, which represents a trend, and the more successful ones are bitcoin, Leyte coin and the new domestic King coin; On the contrary, money laundering, gambling and network theft in the virtual world will have a negative effect on the real economy.

5. Hello, it's OK to invest in bitcoin, and everything else will return to zero.
bitcoin is completely decentralized. Without an issuing institution, it's impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm
anonymity, tax exemption and supervision free
robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear
cross border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records
it is difficult for the cat to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency. But these counterfeit currencies are fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency. Many Shanzhai coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical.
