However, where are the opportunities for these innocent employees? To put it bluntly, some blockchain entrepreneurs are bent on "empty handed White Wolf", and exploit layer upon layer through "deception". Using asymmetric instry information, blockchain, digital currency and other projects are over packaged, giving people a sense of "Hope". This part of the blockchain entrepreneurs' inherent "bad root", to a certain extent, has led to the instry's "sick" development trend

some blockchain entrepreneurs call for embracing the times, changes and the future, emphasizing the charm of decentralized "fairness". But in reality, it is for self-interest, which hurts the interests of job seekers and other related groups, which is a great injustice in itself

The asymmetry of information is not permanent. Blockchain, digital currency and so on are all areas worthy of attention, but they are not the capital that can be used by some entrepreneurs as unlimited squanders all the time. For the job seekers who want to join them, they should polish their eyes, otherwise they may be surprised if they are not careful

Recently, MIT announced that it will launch MIT financial technology laboratory with several top technology companies in the world on July 18, 2018. Its main research directions include blockchain development, privacy security, database, encryption system, etc. ant financial is the only Chinese founder

In an exclusive interview with people, Jiang Guofei, director of ant technology laboratory, said that the former NEC technology VP, who has been wandering in Tokyo Bay and New York Bay for the past 15 years, said that China and the United States are almost on the same starting line in the independent research and development of Frontier core technologies such as blockchain, This is a sight that has never been seen before“ Whether it is Tokyo Bay, New York Bay or San Francisco Bay, they all rise in the blowout of Japan and the United States' comprehensive national strength. Now it's time to go to China, so I'm back. "

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system

blockchain money making methods:

1. Promotion to earn commission

the method of blockchain is to first register the exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates a transaction, you will have a commission

2

currency speculation is like stock speculation. Currency speculation is the lowest threshold for blockchain to make money

3. mining

Mining in bitcoin is the process of bookkeeping. This process needs to be tackled. If you seize the opportunity of bookkeeping right, there will be a reward. The reward is bitcoin. This behavior is called "mining"

wallet is the infrastructure of the block chain, just like the "Alipay" or "WeChat payment" of the block chain. p>

development materials:

1. Blockchain is an important concept of bitcoin, which is essentially a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

2. The blockchain was born from the bitcoin of Nakamoto Tsung. Since 2009, there have been various digital currencies similar to the bitcoin, which are all based on the public blockchain

On January 20, 2016, the digital currency seminar of the people's Bank of China announced that the research on digital currency has achieved phased results. The meeting affirmed the value of digital currency in recing the issuance of traditional currency, and indicated that the central bank was exploring the issue of digital currency. The expression of the digital currency seminar of the people's Bank of China has greatly enhanced the confidence of the digital currency instry. This is the first time that the five ministries and commissions of the people's Bank of China have expressed a clear attitude towards digital currency since they issued a notice on preventing bitcoin risks on December 5, 2013

Blockchain is a new technology, not a disguised form of MLM. It is just claimed by many MLM organizations as "blockchain". In fact, there is no technology. It's just a practice of MLM under the name of "blockchain". The state has issued several announcements to crack down on this kind of MLM. The following is the Xinhua news report on MLM of blockchain:

blockchain is not equal to virtual currency, but also has security risks. Behind the popularity, there is exaggeration with "ulterior motives". Only by removing the flashiness, can the blockchain return to its real application value

invest 80000 yuan, change to 800000 yuan after three months? Shenzhen police cracked a huge fund-raising fraud. Under the guise of blockchain concept and 10 times income, thousands of investors were deeply involved in the case, involving up to 307 million yuan. Under the "veil of mystery" of the blockchain, the illegal elements have taken advantage of their own tricks, and the blockchain has become a "signboard" of economic crimes such as fraud and pyramid selling

why is the blockchain repeatedly "misused" by illegal activities such as pyramid selling fraud? In addition to "unknown", what is the "function" of blockchain technology itself? Since the beginning of this year, with the increase of supervision and the cooling of currency speculation, new opportunities have been brought to the development of blockchain. How about the implementation of blockchain commercial "application" The reporter of outlook news weekly recently concted an investigation

when the three-month "capital release period" promised by the trading platform expired and the staff began to "kick" in the QQ group, Tang Haiyan, who lives in Bao'an District of Shenzhen City, realized that she might have been cheated

previously, Tang Haiyan invested 80000 yuan to buy a virtual currency called "ordinary silver coin" under the introction of her classmates“ The other side said that this currency is the most advanced blockchain technology at present, with Tibetan tea as collateral. He also showed me the "technical white paper". I didn't understand blockchain, so I didn't read it carefully. "

although she doesn't know about blockchain and virtual currency, the high investment income makes Tang Haiyan full of expectations. She told reporters that companies issuing "ordinary silver coins" will regularly split the virtual currency according to the ratio of 1:10, which means that each split will make the value of "ordinary silver coins" in the hands of investors expand 10 times. As long as after a split, her investment of 80000 yuan is equivalent to the purchase of 800000 yuan worth of "ordinary silver coins", which can be sold on the trading platform to obtain huge profits

according to the rules of the trading platform, the newly purchased "ordinary silver coin" cannot be traded immediately, and it must be frozen on the platform for three months before it can enter the "release period". However, after three months, not only did Tang Haiyan not wait for the assets to double, but the 80000 yuan frozen on the platform could not be used for trading

"other investors began to question the authenticity of this investment in QQ group. As a result, the staff of the company kicked these investors out one by one, which made me feel bad." She said

The fact also proves Tang HaiYan's intuition. At the end of March 2018, Shenzhen police detected a huge fund-raising fraud, with the amount of fraud funds as high as 307 million yuan. In this case, Shenzhen Puyin blockchain Group Co., Ltd. involved in the case issued virtual currency in the mode of "blockchain + Tibetan tea" to obtain public deposits. Tang Haiyan was one of the thousands of victims

Shenzhen police investigation found that the company claimed that investors could buy and sell "ordinary silver coins" on the virtual trading platform "jucoin net" to earn a price difference

. In fact, the change of its trading price is that the company used investors' investment funds for behind the scenes operation, and once raised the price of "ordinary silver coin" from 0.5 yuan to 10 yuan, so that investors can taste some sweetness. When a large number of investors entered the market, the company continued to cash out through malicious manipulation of the price trend of "ordinary silver coin", which eventually led to the worthlessness of "ordinary silver coin" in the hands of investors

since 2018, engaging in fraud and pyramid selling under the banner of blockchain has become a common "routine" in new criminal tactics. In April 2018, Jinan police dropped a pyramid selling Gang under the guise of "western development", "national poverty alleviation", "original stocks", "blockchain" and "e-commerce", arrested more than 10 major suspects, frozen more than 100 accounts involved, and seized more than 300 million yuan of funds involved

according to Jinan police, huileyi e-commerce company designed a fake virtual disk on the Internet on the ground that the country is vigorously developing the big data instry, and released a variety of virtual currencies such as "precious currency" and "precious currency"

under the guise of giving away, they presented a certain amount of virtual currency to the New MLM staff, with the price of tens of yuan each. Then, through artificial manipulation, they appreciated the virtual currency all the way to more than 100 yuan or even hundreds of yuan, attracting people who did not know the truth to join. Finally, they "cut leeks" through the periodic fluctuation of the so-called "devaluation" of virtual currency, Finally, the purpose of seeking illegal interests is achieved

in Xi'an, a few days ago, the local police successfully cracked a huge network pyramid selling case under the banner of blockchain. According to the police, the suspect, Zheng Mou, has paid a high salary to the 9 network members, such as Zhang and Lee. Since March 28, 2018, he has gathered pyramid selling and network pyramid selling as a means to sell the virtual Datang coins at the consumption era network platform at the price of 3 yuan each, and manipulate the appreciation rate; p>

at the same time, promotion meetings were held in many cities at home and abroad to attract members. According to the development of members, 28 level agents were set up. In just 18 days, the gang developed more than 13000 registered members. At present, it has been found that the case involves 31 provinces, cities and autonomous regions in China, and the fund involved is as high as 86 million yuan

according to Tencent's 2017 pyramid selling situation awareness white paper released by Tencent security joint laboratory, in recent years, all kinds of overseas capital disk, virtual currency and ICO (initial public offering token financing of blockchain project) projects have emerged in an endless stream, which hide many risks such as illegal issuance, untrue projects, cross-border money laundering, fraud and pyramid selling, As a result, a large number of funds flow overseas. Once the market collapses, runs away or loses contact, investors often have no way to complain and the losses are difficult to recover. For example, Baichuan coin, mark coin, beta coin, dark coin, etc

the reporter of lookout Newsweek interviewed in Guangdong, Shandong, Shanghai and other places and learned that most people know that the concept of blockchain is very popular, but they "don't know where it is", and there are different opinions on the specific functions of blockchain: some people think it is used for "investment and financing", "buying and selling currency", while others think it is "a major invention of the same magnitude as the steam engine", Some entrepreneurs are even more eager to seize this "once-in-a-lifetime opportunity to get rich."

many people in the instry said that it is precisely because people have many misunderstandings about blockchain that criminals have opportunities to fish in troubled waters and mislead investors

First, blockchain is not equal to virtual currency. By the end of last year, the number of domestic ICO participants and the total volume of transactions have doubled, a large number of digital currency exchanges have fled overseas, and the agent investment mode has involved more ordinary people in high-risk investment

in many instries, we media and celebrities form interest alliances with issuers and digital exchanges to endorse and create public opinion for the "air currency" project. In December last year, nine departments including the people's Bank of China identified ICO as "suspected of illegal fund-raising, financial fraud, pyramid selling and other illegal and criminal activities"

in the interview, many people told our reporter that the existence of token has built a set of rights and interests mechanism for the development of blockchain technology, which is indispensable for stimulating the prosperity of blockchain applications“ The market practice in the past five years has proved that blockchain applications without equity mechanism are just like market economy without computers connected to the Internet and money, with greatly reced application scenarios and development speed. " An investor in Shanghai said

in fact, the token represented by bitcoin is only one of the earliest procts to verify the blockchain technology, and the two can not be equated, and the existence of token has obviously negative effects on the development of blockchain

Xiao Wei, chief engineer of network blockchain, told this reporter that the myth of ICO's sudden wealth shakes the R & D concentration of blockchain technical talents, and the myth of "sudden wealth" with hundreds of times of return tests the patience of blockchain technical R & D talents“ Many of the "comrades in arms" in the circle who used to do research and development of blockchain technology have gone to issue coins, and now few of them can insist on doing research and development and application of technology. "

Xu zewei, Secretary of the Party committee of Beijing Internet Finance Instry Association, said that under the background of China's ban on ICO, many domestic start-ups promoting blockchain applications are "selling dog meat with sheep's pawn" and financing through concept packaging of worthless tokens“ ICO has polluted the good atmosphere of innovation and entrepreneurship, and created a kind of speculative proct. Many young people are not thinking about entrepreneurship, but are thinking about issuing money, which makes us have the illusion of getting rich overnight. "

at present, more and more people in the instry begin to think about whether the development of blockchain must rely on the issuance of tokens to achieve incentives. Guo Dagang, Secretary General of Beijing Internet Finance Instry Association, told this reporter that the so-called incentive mechanism is only the theoretical basis for the project party to issue tokens for itself. Huo Xuewen, director of Beijing Municipal Bureau of financial work, also believes that if blockchain does not get rid of the dilemma of issuing currency, it will never find a legal landing mechanism

secondly, blockchain is not omnipotent and its security is at risk. Blockchain is generally considered to achieve three functions:

first, the data stored on the blockchain can not be tampered or forged, and the data has high credibility and credibility; Second, the whole process of the transaction can be traced, which can achieve accurate responsibility tracking; Third, the embedded smart contract in the blockchain can be executed automatically based on the contract, so as to improve work efficiency and rece the risk of default. It is generally believed that blockchain has broad application prospects in finance, logistics, trade and other fields

in fact, blockchain is not omnipotent, and its function has many limitations. It is generally believed that, according to the characteristics of cryptography, in order to tamper or falsify in the blockchain, more than 51% of the nodes need to be controlled in theory. When there are enough nodes in the blockchain, it is difficult to tamper with the trust creation mechanism widely participated by the public

However, in reality, digital currency exchanges are frequently attacked or even stolen. On June 20, 2018, bithumb exchange of South Korea announced on its official website that the exchange had been attacked by hackers and stolen 35 billion won, about 32 million US dollars of cryptocurrency

Ji Xinhua, known as the first generation of "hackers" in China, said that the blockchain will continue to face attacks, and the process of uploading data to the blockchain is prone to information leakage. Some people in the instry worry that once the super computing power of quantum computing is realized, it will also have a direct impact on the blockchain

Zhao Yao, a special researcher of the Institute of finance of the Chinese Academy of Social Sciences, told this reporter that the academic community has confirmed as early as 2013 that the blockchain is not perfect and there are many "cheating" strategies. As long as there are enough economic incentives, controlling attacks of more than 51% nodes does not only exist in theory

Zeng Guang, Secretary General of Shenzhen Internet Finance Association, said that the blockchain technology itself does not have the ability to do so

5. In March 2016, Zhong Xiao, chairman and CEO of Rongze technology, was invited to visit the UK together with Professor Cai Weide, a well-known blockchain expert and head of Beihang's "digital society and blockchain" laboratory, to participate in the big data summit held by IEEE, the world's top academic organization, in Oxford - blockchain forum. Rongze technology has become the first batch of Chinese high-tech enterprises to participate in global blockchain discussions.

Ma Yun: I want to know what bitcoin can bring to the society

at the two sessions, Ma Yun... Oh, sorry, Comrade Ma Yun who doesn't want to wear a red hat didn't attend the two sessions

In November 2017, Alibaba, ant financial services and xiong'an signed a strategic cooperation agreement to build a "digital xiong'an blockchain implementation platform". At present, ant financial services has provided blockchain landing application technology in the rental field in xiong'an. It can be said that xiong'an has become the first pilot field of Ali in the overall implementation project of blockchain technology

Li Chen is the newly appointed compliance director of ant group. Before he was the compliance director of ant group, he was a supervisor of Chongqing ant loan company. According to the online reports, he was also a senior executive of dozens of companies. Most of these companies are affiliated companies of ant group, and his position is also a supervisor, In addition, he is currently a director of hang Credit Consulting Co., Ltd

ant group is a very large company, and a platform it lets many people know is ant flower, so many people think it is a loan company, and the reason why it will temporarily stop listing is because of leverage, and the risk is relatively high

Asia is the earliest continent of human activities. Europa was named after Europa, the daughter of the Phoenician King AgNOR in ancient Greece. Even Zeus, the God of all gods, was fascinated by the fans of Europa. Zeus turned into a docile calf and looked at Europa affectionately. Europa thought the calf was very cute, so she went to it and stroked it. Zeus took the opportunity to turn her to Crete. And she married and gave birth to Minos, ladamantis and other three children. Later, people used Europa to refer to Europe

Europe is the abbreviation of Europa. It is said that the word "Europa" originally came from the word "ILIB" in Semitic, which means "the place of sunset" or "the land of the west"

● Europe covers an area of 10.16 million square kilometers, with a total of 45 countries and regions

● the average height of the whole Europe is 340 meters. The terrain is mainly plain. There are a series of mountains in the south, which are generally called Alps. Among them, Mont Blanc is 4810 meters above sea level, becoming the highest peak in Western Europe. Europe has a dense network of rivers and abundant water. The longest river is Volga River with a length of 3690 km, and the second largest river is Danube River with a total length of 2850 km

● Europe is the only continent with permanent population without tropical climate, and the cold zone climate accounts for a small area, so the climate is mild and the precipitation distribution is relatively uniform

● 99% of the European residents belong to the European race (white), which is a continent with relatively single ethnic composition< There are many languages in Europe, including English, Russian, French, German, Italian, Spanish, etc

● euro is the name of the single currency of the European Union countries. From January 1, 1999 to December 31, 2001, as the transition period, from January 1, 2002, the 12 European Union countries (including Austria, Belgium, France, Germany, Finland, the Netherlands, Luxembourg, Ireland, Italy, Portugal and Spain) use the single currency euro. The euro paper currency is divided into 5, 10, 10, 10 20. 50, 100, 200 and 500. On the front of them are printed windows and gates symbolizing open mindedness and cooperation, while on the north are printed bridges, which means that Europe and the world will maintain communication and mutual support. There are eight kinds of coins, one euro, two Euro, five euro, ten euro, twenty euro and fifty euro. One euro equals 100 euro cents. In European countries, they usually need to be converted into euro. In some large shopping malls, they can also use US dollars directly, but the change they get back may be euro<

Europa

is 670900km away from Jupiter in its orbit

the mass of the satellite is 3138km

the diameter of the satellite is 4.80e22kg

Europa is the sixth known satellite of Jupiter, and it is one of the largest of the 17 satellites of Jupiter. According to scientific prediction, it is one of the satellites that may have life in the solar system

Europa will always be in the ice age, with a thin ice shell and extremely smooth surface. There may be an ocean inside the planet. Of course, if the ocean is liquid, plus the right temperature and carbon material, life may be born inside the planet< In order to solve the mystery of Europa's life, scientists have put forward two feasible methods. One is a two pronged approach using spacecraft and missile weapons. First sent the spaceship to Europa. When it flew near the star, it launched a missile weighing 9 kilograms to the satellite, bombing the surface of the target, throwing the ice pieces to space more than 50 kilometers, and then releasing the gel from the spacecraft to collect it and bring it back to earth. The second is to launch two landing robots to Europa, let them conct field survey, and send the detection results back to the earth, but all instruments must be completely sterilized, even if there is a microorganism on the earth, the detection mission will fail forever< In Greek mythology, Europa is the princess of Phoenicia. One day, she had a dream that two goddesses were in front of her. One was wearing native clothes, the other was wearing Greek robes. The foreign woman said to her, "I will take you away. You will be the wife of Zeus." The native women wanted to keep the princess, but the foreign women took her away

one day, Europa and her friends went out to pick flowers and met a beautiful bull. Cattle are the source of food and clothing for Phoenicians, so the princess stroked the bull. Big white bull is very docile. He signals the princess to ride on his back. As soon as Europa got on the back of the ox, the ox flew away from the Asian continent, dragging the princess to a new world. At this time, the bull became Zeus, the God of heaven. He courted Europa, married her and had children. At this time, the foreign woman in Europa's dream appeared. It turned out that she was Aphrodite, the God of love. She said to the princess, "you are destined to be the wife of Zeus, far away from your motherland. And the land under your feet will be named after you, Europa. "
