blockchain development needs to be determined according to the development methods and functions. Customized development is expensive, and it will be very expensive if there are many and complex functions, Therefore, this specific price can only be expressed in a specific scheme.
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 victimsShenzhen 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 investmentin 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 blockchainZhao 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

it is generally believed that in the Xia and Shang Dynasties, China had money. The earliest currency in China was mainly physical currency. At that time, the currency with the widest circulation, the largest quantity and the longest time was shellfish. Shell, smooth and beautiful, strong and wear-resistant, easy to carry, easy to count. There are a large number of shells unearthed in the sites of Xia and Shang Dynasties, and there are also records about shells in the ancient documents of Shang and Zhou dynasties. In Chinese characters, most of the characters related to value begin with "Bei"
with the rapid development of commodity exchange, the demand for money is increasing, and seashells can not meet people's demand. In the late Shang Dynasty, people began to imitate seashells with copper, and bronze imitation became the earliest metal coin in China. With the extensive use of coinage by workers, seashells, as a kind of natural currency, graally withdrew from China's currency stage. From the appearance of Tongbei in Shang Dynasty to the Warring States period, e to the dominance of vassals, China's currency graally formed four unique currency systems, namely shovel coin, Dao coin, ring coin and Chu coin (yuan Jin and Yi Bi Qian)< After the unification of China by Qin Dynasty, the first emperor of Qin Dynasty promulgated the earliest monetary law of China in 210 B.C., which abolished the formal currency of various countries and designated gold and copper as the unified currency. Gold was used to pay for large transactions, while copper money, half of the round square hole of Qin, was used in daily life. The circulation of Qin banliang coins with round square holes in the whole country ended the disordered state of different shapes and great weight differences of ancient Chinese coins, which was a significant evolution from disordered shape to standard shape in the history of ancient Chinese coins. The shape of this round square hole determined by the Qin banliang coins continued until the early Republic of China
Emperor Wu of the Han Dynasty regained the minting right of the prefectures in the fifth year of Yuanshou (118 BC) and minted five baht coins by the central government. On the surface of the round square hole, the word "five baht" was cast, which determined the unified management of coin casting and issuance by the central government. Wuzhu money has been used in the period of emperor Gaozu of Tang Dynasty for more than 700 years. It is the longest used and most successful currency in ancient China< In 621, Li Yuan was determined to reform the currency system, abolish the five baht coin, and cast "Kaiyuan Tongbao" coin“ The four words "Kaiyuan Tongbao" were written by Ouyang Xun in the early Tang Dynasty. The so-called "Kaiyuan" means to create a new era, while "Tongbao" refers to the general treasure in a unified country. Kaiyuan Tongbao is a reverse of the old system of Qin and Han Dynasties. The weight of money is not written in the text (the weight of money is usually clearly indicated in the text of money since Qin and Han dynasties). It is the evolution of ancient Chinese money from the weight of documents to Tongbao and Yuanbao. Kaiyuan Tongbao coin is the earliest Tongbao coin in China. It was cast in July of the fourth year of Wude (621 A.D.) in Tang Dynasty. It has a history of about 300 years and has never been interrupted. This is also rare in the history of currency. Since then, copper coins in China no longer use money to mark the weight, but use Tongbao and Yuanbao. It has been used until the "Tongbao of the Republic of China" after the 1911 Revolution
the "Kaiyuan Tongbao" in the Tang Dynasty ushered in a new era in the monetary history of China. From then on, the bronze coinage broke away from the tradition of renaming with banliang and wuzhu, and began to transform to abstraction and symbolization“ "Kaiyuan Tongbao" also sets up the standard image of Chinese currency in shape and weight. It takes one coin as the legal weight unit, and weighs one or two for every ten coins. The decimals of ten yuan or two came into being and had a profound influence on later generations
in the Northern Song Dynasty, e to the shortage of copper materials, there was a shortage of money. In order to make up for the shortage of copper money, the government cast a large number of iron coins in some areas, and iron coins and copper coins coexisted. According to the records of the history of Song Dynasty, the cast iron coins in Sichuan at that time always weighed 25 Jin and 8 Liang. To buy a piece of silk in Sichuan, you have to pay 130 Jin of iron. Iron money is so heavy and inconvenient that paper money "Jiaozi" came into being in Sichuan“ Jiaozi uses a unified paper, has a certain shape, is printed with complex patterns, and has anti-counterfeiting secret records“ The appearance of "Jiaozi" is an important evolution from metal currency to paper currency in ancient Chinese currency history“ Jiaozi is not only the earliest paper currency in China, but also the earliest paper currency in the world
Kublai Khan, the emperor Shizu of the Yuan Dynasty, established a unified banknote system and issued "Zhongtong Yuanbao banknotes", which made the Yuan Dynasty the first dynasty to adopt a unified banknote as its basic monetary system< In the early Ming Dynasty, silver was not a legal currency, and gold and silver trading was forbidden. During the reign of emperor Yingzong of Ming Dynasty, the ban on using silver was lifted. So far, silver, as a currency and a measure of value, officially gained its legal status. In the late Ming Dynasty, silver was popular in the whole society and occupied a dominant position in the field of currency circulation
in the first 100 years of the Qing Dynasty, the ingot shaped silver ingots cast in the late Ming Dynasty were still used in various places. At that time, there were various shapes and qualities of silver in circulation on the market. Those weighing less than one or two were called scattered silver pieces, while those weighing from one or two to five Liang were called small pieces, which were used for general trading; For bulk trading, it is a kind of national fake standard silver, which weighs about ten liang of ingots and fifty liang of Yuanbao. When paying, it must be converted into silver and then converted into pure silver, so as to complete the exchange of value for money. It is very inconvenient to use
before and after the outbreak of the Opium War, foreign silver dollars were successively imported into the mainland of China. There were dozens of silver dollars in circulation in the local market, such as Benyang in Spain, Ma Jianyang in the Netherlands, zhanrenyang in Britain, Yingyang in Mexico, Longyang in Japan, etc. As foreign silver counts the value of a piece, it is not necessary to weigh it when it is used, so the people are willing to accept it. For most of the 19th century, it became a choice of currency in China, and also became the catalyst of China's self casting silver dollar. In the years of Daoguang and Xianfeng, imitation silver rose from coastal cities with frequent trade with foreign merchants, and then spread to all parts of the country. It is called Guangban in Guangzhou, fuban in Fuzhou and Hangban in Hangzhou. Among them, the one supervised by Shanghai Daotai is the most regular, with the weight roughly in line with foreign silver dollars. In this situation, in order to maintain national dignity and maintain the monetary system, the Qing government began to plan to cast its own silver< During the reign of Guangxu, Zhang Zhidong, the governor of Guangdong and Guangdong provinces, founded the Guangdong money Bureau in Guangzhou, bought British machines and began to cast silver yuan called Guangxu Yuanbao, which was worth 1 million yuan that year. This is the beginning of China's official casting of silver dollar by machine, and also the origin of modern monetary unit system. The back of Guangxu Yuanbao is decorated with flat dragon pattern, which is also made of imitation silver, so it is called Longyang. After that, the Qing government set up a general foundry of silver coins in Tianjin to manufacture silver coins. The emergence of mechanism currency in the late Qing Dynasty is an important evolution from hand coinage to machine coinage. From then on, not only did great changes take place in the process of casting coins, but also the round square hole coins that had been in circulation for more than 2000 years died.
