Zhang Shousheng, a Chinese blockchain expert

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

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

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

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

The deposit fee of 100 yuan for registration can be returned after completing all courses

tutoring class was given under the line, and the lecture lasted for 4 days, with 7800 yuan per person

RMB 88888 per person for 3 days and 2 nights

...

blockchain? Maybe few people can really answer this question. It is precisely because of the inherent mystery of "blockchain", that many people are eager to pay for knowledge in order to get on the train to the "future"

therefore, all kinds of blockchain training are also very popular, and all kinds of information, such as "scanning code, entering the group to listen to lectures", are filled with the circle of friends, so it is difficult to distinguish the good from the bad. The training costs are even more uneven: 100 yuan, 300 yuan, 7000 yuan or even nearly 100000 yuan...

blockchain training is too hot

I often make up my identity on the dating materials, such as import lighting wholesalers, urban landscape designers, boutique tobacco hotel owners and agricultural loan salesmen. Now, I have finally become an expert in blockchain training courses

and it is reported that a blockchain recruitment advertisement in Beijing recently blew up the circle of friends, requiring candidates to have in-depth research on blockchain technology and cryptography, giving an annual salary of not less than 5 million yuan, and not capped

"this is really the current situation of blockchain talent recruitment. But even so, we can't find people, because it's hard to find qualified people. " Lu Sheng, head hunter of Liepin platform, said

Song Mofei, senior researcher of Suning Institute of finance, said: "in terms of development experience, the rise of domestic blockchain instry has been concentrated in the last two or three years, and few people have long-term blockchain development experience in the talent market." He believes that excessive salary will inevitably attract some speculators, but the increase of salary does not bring about the increase of the application threshold, and even some recruiters only know a little about blockchain technology, which also poses new challenges for the recruitment of blockchain talents

according to Shan Yi, chief data officer of liepin.com, the core of blockchain is the change of social relations and business model based on Internet distributed trust system, which is characterized by decentralization“ There are still many uncertainties in the future development of block chain. There are obvious bubbles at present, and many block chain projects are not reliable. He said

Shenzhen's IT leaders summit has come to its 10th year. As the annual program of China's Internet giants gathering in Shenzhen, Shenzhen and its star enterprise Tencent are trying their best to entertain those bigwigs who come from afar

Zhang Shousheng, Professor of Stanford University, USA:

the generation of blockchain can create a data market. In my mind, the ideal future world is that everyone has their own data, which is a completely decentralized storage. In this way, it is impossible for hackers to hack everyone's personal data and then use some encryption algorithms, In the blockchain, it can really protect personal privacy and make very good calculation

artificial intelligence needs data, but data is often monopolized by centralized platforms, which hinders innovation. Encryption economics creates a data market with correct incentive mechanism for data providers, and artificial intelligence can take off on this data market. In a fair data market, the value of data is measured by cross entropy. In our society, some minorities will be discriminated against. However, in the encrypted data market, the data they provide will receive the most attention. Encryption economics can offset all kinds of prejudices in current social economics

blockchain is a direction of technology. Technically speaking, how much value blockchain can have is still a question mark, which may have great value, but today, the application has not been implemented. We don't deny the value brought by blockchain. In terms of technology, I think it is very valuable and promising, but no one can know how big the prospect is

in the financial field, blockchain is absolutely subject to supervision and is not a free world. Political orientation should be correct. In the field of blockchain, we should adhere to the leadership of the party and accept supervision. Digital currency can not be anarchism, it needs the correct guidance and supervision of the government

now we all focus on the real economy, whether it's entrepreneurship or investment. I think the blockchain itself should create value. If a company issues a coin and doesn't know what to do, it will suddenly be worth tens of billions of dollars, which is completely divorced from value creation

as for the title of classical investors, it's just a joke, or to grab an eye and create some concepts. I believe that 99% of the projects or 95% of the projects will be done by classical VC in 2018

blockchain is very popular, but in fact, institutional investors participate very little. At present, many of them are indivial behaviors. More than 95% of ICO in China is money making, and the really large first-line institutional investors actually participate very little. To be honest, these people can become first-line institutional investors. They are not fooled. They know more than you, see more than you, and read more books than you. How can they be so stupid? They make money from people with lower IQ than you

Wu Ying, chairman of the digital China Federation:

pays close attention to the blockchain and has made a certain investment layout here. Among the three or four companies invested, there are 13 patents. Among the listed companies previously invested, 2 are doing blockchain business. However, it will take some time for blockchain to break out. On the whole, it will take about three years for blockchain to have a direct impact on the economy, but it may be faster than the United States in some aspects. Focus on the application of right protection of works of art, and set up an angel fund to invest in blockchain in the future

talk about big data: the obstacle of data exchange lies in the system rather than technology

Wang Jian, chairman of Technical Committee of Alibaba Group:

data is the material basis of digital economy. Data can neither be shared nor opened, but the value of data can be shared. Uber and didi are great changes in human behavior. What have they changed? In fact, Uber and didi are not sharing cars. In the past, they came out from home in the morning to tell their parents where to go. But with Uber and Didi, you can actually share with a company about where to go today. This is the real change

Guo Wei, chairman of the board of directors and chairman of Digital China Holdings Co., Ltd.

from the perspective of the government, he highly recognizes the value of data, but it is very difficult to implement it. Data itself has a natural segmentation, different people have different cognition of data. Another very important point is the division of interests. Due to the huge benefits brought by mastering the data, some people are not willing to release them. If released, it means the loss of privileges, which is the most difficult part in the process of data access today

from the perspective of today's technology, there is no problem to achieve data access with our technical ability, whether it is traditional technology or the latest developed technology. But the most important obstacle is the system

Yan Yan, founding managing partner of Saifu Asia Investment Fund:

the opening of data is a double-edged sword, and social data should not be open to everyone, because data is useless to more than 95% of people, and there are less than 1% of people, so it is harmful to the society to give them data

The news that bitcoin ranks among the top 30 power consumers in the world is indeed a bit surprising, but if you think about it carefully, it seems reasonable to have such real power. after all, to get bitcoin, you need to consume computing power, which is linked to electricity. In addition, after the appreciation of bitcoin, mining people become more and more powerful, which will naturally make bitcoin a power consumer
