The United States has held several hearings on blockchain virtua

1. blockchain has developed in five stages
1. Germination stage: the real germination stage of blockchain was from 2007 to 2009. In 2008, a Japanese American with the pseudonym of Nakamoto first expounded a new fantasy report on electronic money in the form of a synonym on the cryptography discussion group, and bitcoin came out. As early as 2007, Nakamoto began to explore a series of new technologies to create a new currency. On October 31, 2008, bitcoin white paper was released, and on January 3, 2009, bitcoin system officially began to operate
the main technologies supporting bitcoin system include hash function, distributed ledger, blockchain and asymmetric encryption; It can be seen that these technologies build the initial version of the blockchain, and it can also be said that the blockchain is the underlying technology of bitcoin. During the three years from 2007 to 2009, bitcoin was an experimental stage in which a very small number of people participated, and the real commercial activities had not really started
2. "Geek" niche stage: here, "geek" refers to people who are crazy about Internet technology and take technological innovation as fashion and life. On February 6, 2010, the first exchange of bitcoin appeared. On May 22 of the same year, someone bought two hamburgers with 10000 bitcoins. On July 17 of the same year, the exchange Mt. GOx was established, marking the official inflow of bitcoin into the market. Nevertheless, the only people who can really understand and enter the market to participate in bitcoin trading are geeks who are keen on Internet technology. They discuss bitcoin technology on the forum, mine for bitcoin on their own computers, and then buy and sell bitcoin on Mt. GOx. Now these geeks have become billionaires
3. Market brewing stage: the price of bitcoin was $13 at the beginning of 2013, but on March 18 of the same year, the government of Cyprus closed the bank and stock market e to the financial crisis, which made the price of bitcoin soar, and the highest price rose to $266 in April. On August 20 of the same year, the German government confirmed the currency status of bitcoin. On October 14, China network announced the opening of bitcoin payment channel. In November, the US Senate hearing also confirmed the legitimacy of bitcoin. On November 19, the price of bitcoin rose to US $1242, forming a new high. Nevertheless, the foundation for blockchain to enter the mainstream social economy is not yet available, and the soaring price of bitcoin is only e to over optimistic expectations. The containment of China's banking system, the collapse of Mt. GOx and other events made the price of bitcoin continue to fall. At the beginning of 2015, the price of bitcoin has dropped below $200. From 2013 to the beginning of 2015, the public began to understand bitcoin and blockchain
4. The mainstream period of blockchain: on June 23, 2016, the United Kingdom left the European Union, the fifth nuclear test of North Korea in September, Trump's election in November and other events, the uncertainty of the world's mainstream economy led to the recovery of bitcoin with the function of risk aversion. The market demand was large, and the increase of trading volume made the price of bitcoin soar from $400 in 2016 to $20000 in 2017, The wealth effect of bitcoin and the transaction overflow caused by network congestion of bitcoin have led to the outbreak of other series of virtual currencies, as well as a variety of blockchain applications, resulting in the emergence of a large number of blockchain assets that are 100 times, even 1000 times and 10000 times, which has aroused the crazy pursuit of the world, Subsequently, the Chicago Mercantile Exchange launched bitcoin futures trading, marking that bitcoin has officially entered the mainstream investment proct series, and bitcoin and blockchain have entered the global attention
5. Instry landing stage: after the market frenzy in 2017, the virtual currency and blockchain have been adjusted in terms of market, supervision, cognition, etc. in 2018, returning to rationality. In 2017, many blockchain projects that follow the blockchain technology will graally die out with the cooling of the market, and the projects with real blockchain applications will be initially implemented. 2018 is not only the first year of the blockchain, but also a gold rush period for the blockchain. After the waves wash away the sand, what remains is relatively good gold
from the perspective of the history of blockchain development, blockchain technology is not yet mature and is currently in the growth period. The specific practical application of blockchain is only used in the financial field. It still needs a long way to go to apply blockchain from other instries. However, we should grasp the trend of blockchain and actively learn from the new field of blockchain.

1. Litcoin (LTC) is an improved version of digital currency inspired by bitcoin (BTC). It was designed and implemented by a programmer who worked in Google. It was released on November 9, 2011. Lightcoin and bitcoin have the same implementation principle in technology, but the creation and transfer of lightcoin is based on an open source encryption protocol, which is not managed by any central organization

2. Sunshine coin (SSC for short) is sponsored by Liu Chunyang, vice president of Jinhua express delivery Association of Zhejiang Province, instrial entrepreneur and philanthropist of express delivery instry. As a legal person, Zhejiang Dongyang Yueyin Technology Co., Ltd. is registered with the formal instry and Commerce Bureau, with a registered capital of 10 million yuan. With this as the backing and support, the sunshine elite team affiliated to the company launched the first virtual coin sunshine coin

The English name of Vicat is onecoin, which is a kind of Internet virtual currency term created by the government and is suspected of pyramid selling fraud

in 2017, CCTV announced the list of 350 fund pyramid schemes, with Vicat in the list

in May 2018, Zhuzhou County Procuratorate of Hunan Province prosecuted the last four suspects involved in the third batch of the "3.15" Vicat money online pyramid scheme case supervised by the Ministry of public security to the court

4. Amazon coin

Amazon announced in early February 2013 that it is expected to launch Amazon coins in the United States in May 2013. Amazon coins is a new virtual currency that allows U.S. users to buy apps, games and props in the kindle fire. Amazon will provide tens of millions of US dollars of Amazon coins at that time to let users try and consume the apps, games and props in the app on the kindle fire for free

5. Eth is a kind of digital token of Ethereum, which is regarded as "bitcoin version 2.0". It adopts the blockchain technology "Ethereum", which is different from bitcoin. It is an open-source public blockchain platform with intelligent contract results, and a resonance network composed of thousands of computers around the world. Developers need to pay eth to support the application. Like other digital currencies, ether currency can be bought and sold on the trading platform

3. What is digital currency? Is it the same thing as electronic money and virtual money
the difference between digital currency, electronic currency and virtual currency
in fact, digital currency is a kind of indexed RMB, a legal encrypted digital currency and an alternative currency in the form of electronic currency. Digital currency can be divided into two types: non cryptocurrency (e-gold, XRP) and cryptocurrency (bitcoin)
it can not be completely equivalent to the virtual currency in the virtual world, because it is often used for real goods and services transactions, not limited to online games and other virtual spaces. It is different from Alipay and WeChat, and Alipay, WeChat payment and mobile phone banks are all electronic money, not digital money. The popular digital currencies in 2016 include bitcoin, lightcoin, bitstock, etc. At present, there are thousands of digital currencies issued all over the world
virtual currency refers to the non real currency, especially the currency in the network virtual economy. The issuer is not the central bank, and it can only circulate in a specific virtual environment. In the case of the connection between virtual and reality, virtual currency has its real value. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point, roll counting of Shanda company, u-coin meter ticket launched by Sina (used for igome game), chivalrous Yuanbao (used for chivalrous road game), and grain silver (used for bixue Qingtian game). Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency. For example, bitcoin is illegal digital currency
since the beginning of the year, the relevant person in charge of the people's Bank of China has said that the future of mobile payment is bright, and the central bank is actively studying the relevant research results and practical experience at home and abroad to strive for the early issuance of digital currency. At the digital currency seminar of the people's Bank of China held on January 20, the relevant person in charge of the people's Bank of China disclosed that the central bank has set up a special research team since 2014 to conct in-depth research on the digital currency issuance and business operation framework, key technologies, circulation environment, etc., and strive to launch the digital currency issued by the central bank as soon as possible. At present, the research has achieved phased results
what benefits will digital currency bring to our lives
for this problem, the relevant person in charge of the central bank said that if the digital currency is successfully issued, it will bring many conveniences: it can effectively rece the high cost of the issuance and circulation of traditional paper money, and improve the convenience and transparency of economic transaction activities; It can rece money laundering, tax evasion and other illegal and criminal acts, enhance the central bank's control over money supply and money circulation, better support economic and social development, and help the comprehensive realization of Inclusive Finance; It helps to build a new financial infrastructure, further improve the payment system, improve the efficiency of payment and clearing, and promote the upgrading of economic quality and efficiency. More digital currencies can focus on bitMom

4. Regular blockchain enterprises are not money, and blockchain traces the source to crack down on fake and inferior information
in the past two years, the word blockchain is very popular, and blockchain e-commerce will undoubtedly be the biggest wind outlet in the next decade. However, the instry is in chaos. Many people think that blockchain is money and have many misunderstandings about blockchain. So before we talk about blockchain, we should first talk about the idea of blockchain
blockchain is now understood by most people as "currency". There are too many coin cards in the coin circle, bitcoin and bitcoin. In fact, blockchain has nothing to do with currency. It is a technology, a business ecology and an idea. It is mainly applied in every field. It is extremely similar to the Internet. Talking about blockchain now is like the Internet 20 years ago. What did we talk about the Internet 20 years ago? When talking about its technical architecture, operating system, language, server and so on, it was said at that time that Internet e-commerce was deceptive, because many people had not been exposed to this aspect. In fact, many people have misunderstood blockchain, especially after being confused by the currency circle
When did jiuzero blockchain start? Jiuling started to investigate and prepare from 2016, and has about half a year to investigate all aspects of the blockchain. In 2017, it began to enter the field of blockchain. By 2020, it will be the fifth year. It has gained a lot of experience and achieved a lot in application. We've never played with coins, never engaged in ICO. In the first few years, we didn't make a lot of noise, that is, we should do a good job in technology, platform and browser, and apply them in traceability. We have done a good job in the application of traceability since 2017, and many procts have been launched; In 2018, more than 10000 procts will be applied in traceability. In 2019, it will be further promoted. This year, it will be further developed, and all procts will be opened up in the whole process of visualization. So at the beginning, we used it in the field of traceability. Since 2018, we have used it in the whole blockchain ecology, including blockchain traceability, blockchain invoice, sharing economy, supply chain finance, general points and other applications, as well as the platform technology services we built. We have entered this field in an all-round way, And relatively speaking, it is relatively mature and completely implemented
What's more, why is blockchain on fire now? Why does the development of blockchain reach the height of "thinking"? This is in line with the trend of the times
let's review the history of China's economic development in recent decades. The wealth of Chiang Kai Shek's time was concentrated on the local tyrants, evil gentry and warlords. Mao Zedong liberated most of the common people as peasants, and United most of them was more suitable for the situation of China at that time. Therefore, he defeated Chiang Kai Shek, overthrew the bureaucracy of the local tyrants, evil gentry and warlords, redistributed their wealth, developed the proctive forces again, and completely redistributed their revolution and distribution, Mao Zedong really realized serving the people and let the people live a good life. In the era of large collectives, people go to work in the countryside to earn points. According to the points you earn, how much food can you get. In Deng Xiaoping's time, I felt that this was not right. It might be that the efficiency was not high, and I ate a big pot of rice. Later, I started the reform and opening up. After the reform and opening up, the fields were divided into households according to the number of people. After that, the output increased a lot, which stimulated everyone's enthusiasm, increased the output and improved the efficiency. After the reform and opening up, commercial instrial enterprises began to develop
we can see that economic development is based on the needs of the times. China's reform and opening up has gone for decades, from the traditional economic era to the E-commerce Internet economy, and now the blockchain has come out, also because of the new problems of wealth distribution in the Internet era
in the Internet era, social wealth is highly concentrated on several platforms, such as Alibaba, Tencent, Internet, Jingdong, etc. the Internet e-commerce leaders have too strong a say in finance, resources, procts and other aspects. Social development has completely lost its balance. The uneven distribution of wealth has made the rich richer and the poor poorer. The instrial enterprises without money, including the whole of China, are now difficult to survive except for the monopolized central enterprises. At this time, there needs to be another revolution in business. The proctive forces must be redistributed and readjusted. It happens that blockchain is born to meet the needs of the era of transportation
the rules and mechanisms of blockchain are completely open and fair, can not be tampered with, and can not be decentralized. The oligarchs of institutions are removed to form a sharing economy for common development. Why does the government support blockchain so much? Because the government can fully enter the field of blockchain for supervision, and the privacy of citizens can be protected. Personal information in the Internet is not protected, and personal information in the blockchain is in their own hands. In the era of Internet e-commerce, oligarchs monopolize information resources. There are too many fake and shoddy procts and too many false information, so we have no way to distinguish them
at this time, the rule mechanism of decentralized supervision of blockchain emerges as the times require. Blockchain is not only a technology (it has made some improvement and promotion in the original Internet technology), but more importantly, it can solve the problems that cannot be solved by the Internet, traditional e-commerce and traditional ecology, such as traceability. Traceability in the Internet age can be falsified. A traceability source can be pasted anywhere, but the traceability of blockchain is different. The technology of blockchain is real. Everyone can participate together. Through distributed storage, everyone can get the data, and then all things can be traced, including procts and invoices, Including a person to send a message can be traced, stored, fidelity
the traceability of blockchain starts with raw materials, then proction and processing, then warehousing, sales, etc. every link should be visualized, with pictures, videos and words, which will leave traces of every link. Only in this way can we make everyone trust completely and be fair, open and transparent when there are too many fake and shoddy procts and lack of trust. In short, blockchain is to solve the problem that the Internet can not solve
when it comes to blockchain, bitcoin is the first thing that many people think of. In fact, bitcoin's contribution to the world is to put forward a rule and mechanism. Bitcoin itself has no value. It has no proct and no support. But its technology and concept are very good, because this technology can't be fake. The source code of this technology is open source and can be shared. Its technology uses the idea of blockchain
as soon as the rules and mechanisms of blockchain come out, they are sought after by everyone. However, in recent years, they have been confused by money. That kind of money is deceptive and runs counter to blockchain. On the contrary, it makes people distrust blockchain because they don't know enough about blockchain and think blockchain is money. Because if you want to understand a field, just like jiuzero blockchain has entered its fifth year, you are engaged in blockchain ecology, blockchain traceability, blockchain digital integration, blockchain technology development, blockchain browser development and so on every day. In this field, you are still learning constantly, because it is not easy to learn a field thoroughly. The reason why we have been very motivated in the past few years is because we know that it is a big trend and coming. Just like the Internet 20 years ago, many people don't believe, understand and turn a deaf ear to it. But ten years ago, Tencent, Alibaba, Huawei and other big enterprises got up. At the same time, now this opportunity is in front of us. Can we seize it? This is a question worth thinking about
finally, let's make it clear that blockchain has nothing to do with currency
for regular blockchain enterprises, the government has requirements and certification standards
standards: three basic requirements (patent, soft work, registered company in national blockchain Park, paid in registered capital, dedicated blockchain R & D funds), four landing application standards (blockchain browser, website, blockchain application scenarios, blockchain procts), five kinds of blockchain professionals (blockchain finance professionals, Blockchain digital professionals, blockchain credit management professionals, blockchain software development professionals, blockchain encryption technology professionals, and employees with bachelor degree or above who have been employed for more than one year) can get six basic subsidies
in the blockchain instry, there are at least tens of thousands of companies doing money and ICU. They all say that they are regular, but can they take out these certificates. The document points out that as long as the company has digital currency or ICO, it is not a blockchain company
under the background of this era, the ideas, rules and mechanisms, decentralized supervision and privacy distribution of blockchain can protect everyone's interests, redistribute proctivity assets, prevent the interests from being too concentrated on certain oligarchs and institutions, let everyone participate together, and let everyone exert their energy together to fight against counterfeiting, tax evasion, tax evasion, tax evasion, etc The real purpose of blockchain is to crack down on false transactions and create a conscientious ecosystem that can protect the interests of the people and provide hematopoietic function.

5. At present, the state has not yet recognized
some time ago, the state specially cracked down on this virtual currency
so we should be cautious in investing in virtual currency

6.

Because f acebook wants to be recognized by Swiss currency, it has to apply for payment license . Swiss bank may be in charge of this part. After all, Swiss bank's confidentiality is absolute. According to the issuance plan of Libra, the financial services provided by this digital money bank plan will significantly exceed the simple payment system, which means that the more demand is

, FINMA said on Wednesday, It is expected to provide digital trading and payment services to billions of potential users. But then, many central banks, finance ministers, legislators and many privacy organizations around the world questioned Libra and expressed concern (Li Ming)

7. Xu Mingxing, as a veteran of the blockchain instry, has a very forward-looking vision. He has experienced the whole development process of the blockchain instry. Xu Mingxing realizes that many procts of domestic cutting-edge instries still rely on the introction of foreign technology or direct import. As an emerging instry, if talents are equally important in the field of blockchain, but we do not pay attention to the cultivation of talents, the future of blockchain will be restricted by developed countries just like many traditional instries because of talents.

8. Is the so-called global consensus in the blockcompany piled up by people? It's not accumulated by people, it's accumulated by knowledge.

9. The earliest designer of China's virtual currency blockchain is Mr. Zhang Ronghuan. You can go online: Zhang Ronghuan's gene of digital economy indicates that bitcoin blockchain mode is the gene of digital economy in the top-level design of ecological civilization.
