The first three virtual currencies

1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009[ 1] &# 160; According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity.

2. First, most of the virtual coins issued today are decentralized, but in this regard, the virtual coins issued by the central bank must not be able to do so. It must be centralized and easy to adjust
Second, the value of money must be stable in a certain period of time, and it will not be as high as virtual currency such as BTC. The main purpose of the central bank's issuing virtual currency is to replace the current paper currency to a certain extent. That is to say, if a virtual currency assumes a fixed value of one yuan, it will be one yuan for a long time, It will not and will not be allowed that a virtual currency will rise to 100 or even more than 1000
thirdly, the most conservative estimate is that once issued, domestic enterprises or banks can choose whether to pay virtual currency or cash currency (RMB) when they pay wages or withdraw money. To a certain extent, cash will exist for a long time, instead of being issued all at once, all of them will be replaced by virtual currency, and all cash will be invalid, It's not realistic. It can only be said that it will be replaced graally
Fourth, the purpose of the central bank to issue virtual currency is to replace the current paper currency. Therefore, there must be a lot of similarities between this kind of virtual currency and the current paper currency. You can also directly replace the paper currency with the virtual currency, so you can have a good understanding of the nature of the virtual currency issued by the central bank. Therefore, the central bank's virtual currency is absolutely not allowed to appear, and the currency price is falsely high
therefore, it can be seen from the above points that the central bank's virtual currency is a new type of RMB, but it used to be physical, but now it is electronic and virtual. This is just like the use of real gold and silver in ancient times, and the appearance of "Jiaozi", that is, paper money, is only a kind of progress of the times. Other things are meaningless, just for the convenience of transaction, portability or personal property security. If you want to make money by investing in currency speculation, you can give up the idea. It's meaningless. If you just want to experience the freshness brought by the new currency, just wait quietly. Come out early, come out late, come out sooner or later. But then again, I'm looking forward to it.

3. At present, digital currency is not really in circulation in any country. In South America, there was a small country that wanted to issue its own sovereign digital currency, but there was no latest progress. Of course, China, Britain and other big countries have planned to issue digital currency, but it is still in a testing stage and has not really implemented it
the first country to recognize bitcoin as legal was Germany, which first defined bitcoin as an alternative currency. Of course, in the future, sovereign digital currencies may be popular, and digital cryptocurrencies such as bitcoin, Ruitai coin, Laite coin and vitality coin will become a supplement.

4. What is GCB coin< First of all, GCB is a payment system, which can pay, receive and store any currency, including US dollar and other currencies, as well as bitcoin, bitcoin and even gold. GCB is more comprehensive, not only a currency, but also a platform, and provides instry standards,

it will affect the world in a larger scope<

GCB: E-mail Exchange Protocol SMTP, currency convertibility protocol

rtxp< The main features of GCB coin are as follows:

1. It can be freely convertible into legal currencies such as US dollar, euro, British pound,

RMB; Virtual currency, bitcoin, lightcoin; Metal currency yellow

gold, silver, etc< (2) in the first eight months of the initial issue of 12 million, the amount of additional issuance with compound interest of

10% per month should be maintained, that is, 1.2 million additional issuance in the first month,

increasing compound interest; In the next three years, it will maintain 5% of the monthly amount of

; In the next two years, it will maintain 3% of the monthly additional issuance; Finally,

in about 17 years, it will maintain 1% of the monthly additional issuance, and the less the

lines are issued, and the promotion rewards are all distributed to the participating

users through the wallet computing power. Among them, 50% are issued by wallet ranking and 50%

by promotion. Through the way of open source code to ensure that

program open, will not be modified! Just, fair, open

the value belongs to the user. Bitcoin proces bitcoin according to the CPU computing power of mining machinery

III.

while GCB is completely different. According to the random ranking of daily GCB holdings of

users, 50% of daily new GCB

issued will be calculated according to the higher ranking of wallets, and the more GCB will be allocated to each day. According to the user group calculation, 50% of the daily new GCBs are allocated according to the proportion of wallet link user group in the total calculation. The larger the number of link user group, the more new GCBs are allocated daily< Fourth, payment is as simple as wechat, supporting simple, fast and secure payment and free transaction between users<

Introction to GCB coin

we live in an era of extremely developed communication. We can communicate with friends anywhere in the world at any time,

by phone,

by email, instant messaging, etc; Have you ever thought about how to build a global communication system? How many countries and operators can make such a huge system run<

(modern communication developed) take e-mail as an example. In the early years of Internet, e-mail service appeared. However, before 1989, the e-mail you registered could only transfer e-mail with users registered with the same company. That is to say, if you use QQ e-mail, You can only send email to his

QQ email users, but not to 126 email

boxes, or all other email such as Yahoo email. Now

think about how unreasonable it is, but at that time, it was very normal

why can the email developed by different companies communicate with each other

? Until SMTP (Simple Mail Transfer

protocol) has graally become the recognized standard for transmitting e-mail on the Internet. All companies have developed according to this protocol standard, so today all

e-mails can be sent to each other, If anyone fails to comply with

SMTP, it will become a meaningless

Island mailbox

(SMTP protocol)

therefore, "Protocol" is the answer

in order to build such a huge global system, so many countries and institutions are needed to cooperate, and the "agreement" must be followed! Internet

TCP / IP protocol is used for communication at the bottom layer of the network, and HTTP

protocol is used for website; There are all kinds of communication protocols and associated standards; When most people accept these protocols and standards, the global

system can be established in an orderly way<

(TCP / IP protocol, HTTP protocol)

however, in today's Internet has been so developed, compared with the communication system, the monetary payment system we use is at least a few decades behind, just like the e-mail system in the 1980s, it is still closed but not connected! Different countries have different

currencies, and different banks can't remit money directly, so they need to transfer money through one or more third-party institutions, and pay a lot of service charges for it! When most of the information transmission is free,

there are still many obstacles to money transfer, such as wire transfer and credit card payment<

(currency communication is backward)

the Internet has a history of 40 years, but there is a huge gap between Internet communication

and Internet Finance: Internet communication

has been flattened through the point-to-point distributed network, but the settlement and delivery of transaction

is always centralized, This makes the financial exchange still run at the level of the 1970s

(Financial Island, no general agreement)

in the electronic age, money is actually just another kind of information: loan information stored in the electronic general ledger. So why is there such a big difference between the way computers transfer accounts and the way they transfer information

compared with other information, how can money transfer be so slow,

expensive and complex? The fundamental reason is that there are too many independent networks and independent payment systems with centralized proprietary software, and they are all isolated islands without mutual connection

(global money agreement?)

if there is a "general agreement" about money, which can connect all independent

financial systems like

SMTP, then our payment can be as simple and convenient as

sending email, anytime and anywhere! No matter what kind of currency is used,

it can be paid to anyone and converted into any currency. At any time,

you only need to issue an instruction to complete it<

(rtxp protocol)

and this kind of internet protocol about money transaction has appeared,

it is rtxp protocol (49.213.12.240/24 transaction agreement

protocol)! "Payment Protocol" of Internet

developed by opencoin company of Silicon Valley in the United States is free and belongs to anyone and has no central control organization, just like SMTP! At present, it has obtained the investment of

IDG capital,

Sen Horowitz venture capital company and other heavyweight institutions! The world

must be ready to accept the evolution of the financial system by the Internet<

(GCB coin is born)

based on rtxp protocol, GCB is born! It is not only a virtual currency, but also a set of global payment system supporting rtxp protocol, just like the application of rtxp,

and expansion of GCB without QQ mailbox, 126 mail box and SMTP protocol<

summary:

GCB is a free currency system that can not only increase in value but also reproce. It breaks the shackles and is a milestone in currency design

maybe you have missed the investment opportunity of bitcoin gold, but do you want to miss another investment opportunity of life gold<

GCB will give you another gold investment opportunity, you know,

investors<

GCB will be officially launched for trading at the end of April 2016. After buying

well, it will continue to appreciate when it is put into the wallet<

5. In 2016, the central bank did not issue digital currency, but in 2016, the central bank led a digital currency seminar in Beijing. The relevant person in charge of the central bank said that digital currency should be launched as soon as possible. But later, Zhou Xiaochuan, the Central Bank of Hangzhou, said that the time for issuing digital currency is not ripe, and it may take ten years. Moreover, the design concept of the digital currency to be issued by the central bank is different from that of the digital cryptocurrency such as bitcoin, Ruitai coin and Laite coin, which is not a decentralized digital currency.

6. The earliest electronic currency is bitcoin
on November 1, 2008, a person who called himself Satoshi Nakamoto posted a research statement on a secret cryptography review group, stating his new idea of electronic currency bitcoin came out, and the first transaction of bitcoin was completed. Bitcoin has got rid of the constraints of third-party institutions with the help of information technology, which Nakamoto calls "regional chain". Users are willing to dedicate the computing power of CPU and run a special software to be a "digger", which will form a network to maintain the "regional chain". In the process, they also generate new money. Trading also extends on this network. The computer running this software can solve the problem of irreversible code, which contains several trading data. The first miner to deal with the problem will get a 50 bitcoin reward, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes
bitcoin was originally a kind of network virtual currency, similar to Tencent's q-coin, but it has been able to buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique. In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
on January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the current situation of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
recently, the news of bitcoin's soaring price appeared on the news, and it began to attract people's attention again!

The earliest currency in the history of China is the commodity shell, which is also the earliest currency in the world

Shell is the earliest currency in China, and it was used as currency in Shang Dynasty. In Chinese characters, most of the characters related to value are related to "Bei"

with the development of commodity exchange, the demand for money was increasing, and seashells could not meet people's demand. In the Shang Dynasty, people began to imitate seashells with copper

The appearance of copper coin is a significant evolution from natural currency to artificial currency in ancient Chinese monetary history. With the extensive use of artificial coins, seashells, as a natural currency, graally withdrew from China's currency stage

extended data:

China is one of the earliest countries in the world to use currency, with a history of 5000 years. In the process of formation and development of ancient Chinese currency, it has experienced five extremely significant evolutions:

the evolution from natural currency to artificial currency, from disordered shape to unified shape, from local coin to central coin, from document weight to Tongbao, Yuanbao, and from metal currency to paper currency "Jiaozi"

From the spring and Autumn period to the Warring States period, China has established four monetary systems: cloth coin, knife goods, ant nose money and ring money. Later, it went through the Qin, Tang, Han, Wei, Jin, southern and Northern Dynasties, until December 1, 1948, the people's Bank of China was established and issued the first set of RMB

9. Banknotes are widely used in the world today. The earliest banknotes in the world are jiaozi in Cheng, Sichuan Province in the Northern Song Dynasty. China is the first country in the world to use currency. According to the literature records and a large number of unearthed cultural relics, the origin of Chinese currency has a history of at least 4000 years. The development of Chinese currency culture has a long history, from the original shell coin to cloth coin, knife coin, round coin, ant nose coin and fangkong coin popular after the unification of China by the first emperor of Qin Dynasty. In the Northern Song Dynasty, jiaozi appeared in China. The emergence of paper money is a great progress in the history of money. Some people think that the origin of Chinese paper money can be traced back to the "white deer skin money" of Emperor Wu of Han Dynasty and the "flying money" of emperor Xianzong of Tang Dynasty. During the period of Emperor Wu of Han Dynasty, the National Treasury was empty because of the long-term war with Xiongnu. In order to solve the financial difficulties, the "three baht coins" and "white gold coins" (alloy coins made of silver and tin) were coined, and the "white deer skin coins" were issued at the same time. The so-called "white deer skin coin" uses the white deer skin of the palace as the coin material. Each piece is one square foot, and the surrounding color is painted. The value of each piece is 400000. Because its value is far away from its own value, the "white deer skin coin" is only used as a tribute between kings and princes, not used in the field of circulation, so it is not a real sense of paper money, only a pioneer of paper money“ "Feiqian" appeared in the middle of Tang Dynasty. At that time, when merchants went out to do business with a large amount of copper money, there were many inconveniences. They first went to the official to issue a certificate, which recorded the place and the number of coins, and then went to other places to withdraw money and buy goods with the certificate. This certificate is called "feiqian"“ In essence, "flying money" is only a kind of exchange business. It does not intervene in circulation and does not function as currency. Therefore, it is not paper money in the real sense. In the Northern Song Dynasty, "Jiaozi" in Cheng, Sichuan Province was the beginning of real paper money. It is not accidental that paper money appeared in the Northern Song Dynasty, it is the inevitable proct of social, political and economic development. The commodity economy developed rapidly in Song Dynasty, and more money was needed in commodity circulation. However, the shortage of copper money at that time could not meet the demand in circulation. At that time, the iron coin was used in Sichuan area, which was of low value and heavy weight, and was extremely inconvenient to use. At that time, one copper coin was worth ten iron coins. The weight of one thousand iron coins was 25 Jin for a large coin and 13 Jin for a medium coin. It costs 20000 yuan to buy a piece of cloth. It weighs about 500 Jin. It takes a car. Therefore, we need light money objectively, which is the main reason why paper money first appeared in Sichuan. Moreover, although the Northern Song Dynasty was a highly centralized feudal autocratic country, the national currency was not unified, and there were several currency areas, which were independent and not universal. At that time, there were 13 routes (administrative units in Song Dynasty) dedicated to copper coins, 4 routes dedicated to iron coins, and Shaanxi and Hedong used both copper and iron coins. The use of paper money can prevent the outflow of copper and iron money. In addition, the Song Dynasty government was often attacked by Liao, Xia and Jin Dynasties, and the military expenses and reparations were very large. It also needed to issue paper money to make up for the fiscal deficit. Various reasons contributed to the emergence of "Jiaozi". The first jiaozi was issued freely by merchants. In the early years of the Northern Song Dynasty, "Jiaozi shop" appeared in Cheng, Sichuan Province, which specialized in keeping cash for merchants carrying huge sums of money. The depositor delivers the cash to the shop owner. The shop owner temporarily fills in the amount of cash deposited by the depositor on a roll made of paper, and then returns it to the depositor. When the depositor withdraws the cash, he pays the shop owner the interest of 30 Wen, that is, 3% of the deposit fee. This paper voucher which temporarily fills in the deposit amount is called "Jiaozi". At this time, "Jiaozi" is just a kind of certificate of deposit and withdrawal, not currency. With the development of commodity economy, "Jiaozi" has been used more and more widely. Many merchants set up jiaozi shops which specialize in issuing and exchanging "Jiaozi", and set up jiaozi sub shops in various places. Due to the fact that jiaozi shop owners abide by the credit and take it as they come, the printed "Jiaozi" pattern is exquisite, it is hidden as a mark, there are mistakes between black and red, and it is difficult for others to forge their own words, so "Jiaozi" has won a high reputation. In order to avoid the trouble of carrying coins, there are more and more cases of large-scale transactions between merchants who directly use "Jiaozi" to pay for money at any time. It is in the repeated circulation process that jiaozi has graally acquired the character of credit currency. Later, jiaozi shop owners found that only using part of their deposits would not endanger the reputation of Jiaozi. So they began to print jiaozi with uniform denomination and format, which was issued to the market as a new means of circulation. This kind of "Jiaozi" has been the symbol of coins, and has really become paper money. However, jiaozi was not recognized by the government at this time, and it was still a private issue. But not all jiaozi shops are law-abiding and trustworthy. There are some greedy shop owners who are greedy for profits, who cheat maliciously and shut down their business after they have made excessive payments; Or misappropriate deposits, run other business failure and bankruptcy, so that the "Jiaozi" can not be cashed. In this way, when depositors can't withdraw money, they often cause trouble and litigation. Therefore, ring the reign of Jingde (1004-1007), Zhang Yong, the governor of Yizhou, reorganized jiaozi shops, eliminated outlaws, and managed them exclusively by 16 wealthy merchants. So far, the issue of Jiaozi was approved by the government. In the first year of Tiansheng (1023) of emperor Renzong of the Song Dynasty, the government set up jiaozi business in Yizhou. One or two officials of the Jing Dynasty acted as supervisors to preside over the distribution of Jiaozi, and "set up a papermaking house to eliminate the disadvantages of forgery" to strictly control the printing process. This is the earliest paper money officially issued by the government in China - "guanjiaozi". It issued paper money 600 or 700 years earlier than the United States (1692), France (1716) and other western countries, so it is also the earliest paper money in the world“ In the early stage of the issue of guanjiaozi, its shape was modeled on the private relationship among the people, and stamped with the seal of the state, but the amount of money temporarily filled in was different, generally from one to ten, and the scope of circulation was specified. In the reign of emperor Renzong of the Song Dynasty, it was changed into five Guan and ten Guan. By the time of emperor Shenzong of the Song Dynasty, it was changed to two kinds: Yiguan and wuwuwen. There are also restrictions on the amount of issue. It is stipulated that the issue shall be divided into three years (two years in full) for each sector, and the new one shall be exchanged for the old one. The first jiaozi issue was 1 256 340 units, with a reserve capital of 360 000 units (taking Sichuan tieqian as the note capital), and the reserve was equivalent to 28% of the issue“ The circulation scope of Jiaozi was basically limited in Sichuan. Later, although it was popular in Shaanxi and Hedong, it was soon abolished. In 1107, the Song government changed jiaozi to qianyin and jiaoziwu to qianyin. In addition to Sichuan, Fujian, Zhejiang, Huguang and other places still use "Jiaozi", other roads use "qianyin". Later, Sichuan changed jiaozi to qianyin in 1109“ The biggest difference between "Qian Yin" and "Jiao Zi" is that it takes "Luo" as the unit“ The paper, printing, picture and seal of "Qian Yin" are excellent. But "Qian Yin" did not buy notes, and was not allowed to exchange them, so the value of paper vouchers dropped sharply. In the Jiading period of the Southern Song Dynasty, each coin was only worth 100 Wen in cash“ The emergence of "Jiaozi" has facilitated commercial exchanges and made up for the shortage of cash, which is a great achievement in the history of currency in China. In addition, "Jiaozi", as the earliest banknote issued in China and even in the world, also occupies an important position in the history of printing and printmaking, which is of great significance to the study of ancient banknote printing technology in China
