Shanghai's first virtual currency

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.

3. The mainstream news media of such a grand meeting are all reporting. Basically, they can't access any information of the meeting on the Internet. The information of the meeting seems to be confidential. I haven't heard of this meeting in the coin circle
this kind of conference is often a pyramid marketing conference or a direct marketing conference, and the participants are basically the same kind of people. The scale of the conference is often relatively grand. At present, it is a kind of illusion to the participants, which makes people think that the organizers are powerful
it is suggested not to attend these so-called international virtual currency summit. The people who attend the summit are basically no real talents, they are just liars. There are only some real talents in the meetings held in the coin circle, such as the Ruitai coin conference designed by teacher Shaqian, and the meetings held by Huo coin.com and OK are attended by the big men in the coin circle. Of course, the momentum of the recent digital currency like the gold card is still good.

Today's society is a society of rapid development. Many people like to buy things on the Internet. At the same time, the payment method has also changed greatly. This time, Shanghai began to issue digital currency, which also aroused heated discussion among netizens on the Internet. In fact, digital currency is of great benefit to the common people

at the same time, the central bank's digital currency belongs to legal currency, which is the same as cash. We now set up various payment category B in private Payment institutions or platforms, but the central bank's digital currency will not have this situation. As long as we can use electronic currency transactions, we can accept the central bank's digital currency, From this, we can see that its coverage is very wide. At the same time, from the perspective of legal power, the efficiency and security effect of digital currency is the best. Because it is endorsed by the state, it will not be stolen. At the same time, its settlement method is different from other software. At the same time, the central bank's digital currency will not go bankrupt, unlike other private apps

It's illegal to issue coins in China. Illegal enterprises can't be registered in China Article 3 of the regulations of the people's Republic of China on the administration of RMB has made clear provisions. The relevant laws and regulations are as follows:

regulations of the people's Republic of China on the administration of RMB

Article 3 the legal tender of the people's Republic of China is RMB. No unit or indivial may refuse to pay all public and private debts within the territory of the people's Republic of China in Renminbi

Article 28 No unit or indivial is allowed to print or sell token tickets to replace RMB in circulation on the market

extended information:

People's Bank of China's "risk tips on preventing illegal fund-raising in the name of" virtual currency "and" blockchain "

under the banner of" financial innovation "and" blockchain ", By issuing so-called "virtual currency", "virtual assets" and "digital assets" to absorb funds, the legitimate rights and interests of the public are infringed. This kind of activity is not really based on blockchain technology, but hypes the concept of blockchain, illegal fund-raising, pyramid selling and fraud. It mainly has the following characteristics:

1. Obvious networking and cross-border. Relying on the Internet and chat tools for transactions, and using online payment tools to balance funds, the risks spread widely and spread quickly. Some lawless elements set up websites by renting overseas servers to carry out activities for domestic residents and control illegal activities remotely. Some indivials claim in the chat tool group that they have obtained the investment quota of overseas high-quality blockchain projects and can invest on their behalf, which is most likely fraud. Most of these illegal funds flow overseas, which makes it very difficult to supervise and trace

Second, deception, temptation and concealment are strong. They use hot concepts to hype, fabricate various "tall and tall" theories, and some also use celebrity "big V" platforms to publicize. They use airdrop "candy" as temptation to claim that "currency value only rises but not falls", "investment cycle is short, income is high, and risk is low", which has strong bewitching. In practice, criminals illegally make huge profits by manipulating the price trend of the so-called virtual currency, setting profit and withdrawal threshold

in addition, some criminals also issue tokens under the guise of ICO, IFO, IEO and other fancy items, or speculate in the way of IMO in the name of sharing economy, which has strong concealment and confusion

Thirdly, there are many kinds of illegal risks. Through public publicity, criminals use "static income" (currency appreciation profit) and "dynamic income" (development offline profit) as t to attract public investment, lure investors and development personnel to join, and constantly expand the fund pool, which is characterized by illegal fund-raising, pyramid selling, fraud and other illegal behaviors

The essence of money is the general equivalent. In the process of the continuous development and evolution of human history, it has gone through the stage of physical money, the stage of substitute money, and then entered the stage of credit money. In primitive society, people exchanged livestock, salt, shells and other hard to get goods as general equivalents

in the long history, the emergence of metal currency makes the economic life achieve unprecedented prosperity. However, e to the inconvenience of carrying metal money, paper money became the mainstream form of money. With the rapid development of modern information technology, e-money has come into our life

if the evolution process from physical money to value symbol paper money is the first qualitative leap in the history of money development, then the evolution process from paper money to electronic money is the second qualitative leap in the history of money development

from the perspective of money form, physical money itself is a commodity in addition to performing monetary functions; Paper money is a symbolic tool of value for commodity exchange and a credit currency; Electronic currency is the proct of highly developed Internet economy and continuous progress of bank payment and settlement technology. It not only has the function of traditional currency, but also can continuously improve digital currency

At the same time, the virtual money market based on electronic information is also booming. By the end of 2014, the number of Internet users in China had reached 632 million, including 517 million registered users in the online game market and 114.48 billion yuan of sales revenue, an actual increase of 37.7% over the previous year

a huge virtual space based on the Internet has been formally formed. As a kind of virtual currency with intrinsic value, convenient online trading behavior, low transaction cost, and service providers' issuance, it emerges as the times require

first of all, from the functional analysis. Virtual currency is a kind of transaction medium in the Internet virtual space, which has the function of value scale, but the value scale of virtual currency is different from that of legal currency

using virtual currency to purchase virtual procts and services can only be within the scope specified and allowed by the issuer of virtual currency (Internet operator), and the size of this scope depends on the number of virtual procts and services. If the virtual procts and services provided by the website are large enough, the scope of virtual currency will be large

the currency value of virtual currency depends on the pricing of virtual currency by issuers. When no currency can communicate between virtual cyberspace and reality, the pricing of procts and services is still based on real RMB. That is to say, when issuers of virtual currency price their own virtual currency, they should first convert the price of virtual currency based on RMB

7. The environmental protection concepts and methods of the same environmental protection units and organizations are very different, and the things that need environmental protection volunteers to do are also very different. Some environmental protection organizations engage in environmental ecation, they need volunteers to engage in publicity, websites and so on; Some environmental protection organizations engage in environmental life, they need volunteers to participate in bird watching, garbage collection, recycling of waste batteries and so on; Some environmental protection organizations are engaged in environmental protection activities. They organize volunteers to plant trees and grass seeds; Some environmental protection organizations are engaged in environmental monitoring and protection, and will organize volunteers to report pollution sources and fight against pollution units; Some environmental protection organizations are nature reserves. They organize volunteers to do environmental surveys, observe data, and publicize; Some organizations promote environmental protection procts, and ask volunteers to promote biogas digesters, firewood saving stoves, and so on.

8. Hello, most of these platforms are not compliance channels, or even illegal,
but there is no problem, so it can not be determined
few investors and poor liquidity; Lack of supervision and serious manipulation.
