Consciousness chain OMT blockchain

1. Triporg travel: a travel service application using the underlying technology of blockchain, which can provide travel prepaid services such as train tickets and air tickets.

2. 1. What is the technology of blockchain?

3.

At present, blockchain is not only applied in the financial instry, but also in the following instries, such as banking, payment and cash transaction, network security, academic records and academia, election, network and Internet of things, prediction, right and so on. There are still many areas that need blockchain technology. It can be imagined that the Internet + we mentioned before will become a blockchain + situation in the future

from the demand side, finance, health care, notarization, communication, supply chain, domain name, voting and other fields are beginning to realize the importance of blockchain and try to connect technology with the real society

from the perspective of the investment side, the supply of investment funds for blockchain is graally rising, the investment enthusiasm of venture capital is also rising, and the investment density is increasing. The supply of funds at the supply side is expected to promote the further development of technology

from the perspective of market application, blockchain can become a market tool to help the society rece the cost of the platform and make the intermediary institutions become the past; Blockchain will promote the shift of the focus of the company's existing business model, which is expected to accelerate the development of the company

from the perspective of underlying technology, blockchain is expected to promote the transformation of data recording, data dissemination and data storage management; Blockchain itself is more like an open source protocol at the bottom of the Internet, which will touch or even completely replace the underlying basic protocol of the existing Internet in the near future

from the perspective of social structure, blockchain technology is expected to integrate law and economy and completely subvert the original social supervision mode; Organizational form will change because of it, and blockchain may eventually lead people to a distributed and autonomous society

Where should we start to learn blockchain

first of all, we need to have a comprehensive understanding of the source and cognition of blockchain from a macro perspective. Why do we need to do this? Because if we don't understand, we will have no voice. We don't know how to judge that the next outlet is blockchain. Even if people follow suit, we also need our own learning solution as support. So, what do we need to know? I have listed the contents, For your reference only, if you already know something about it, you can skip this step:

1), basic theory of blockchain

2), basic programming (computer software and hardware foundation, character set and character encoding, HTML5 + CSS3 and other front-end technologies, ECMAScript + BOM + DOM, jQuery, node.js, Ajax and express framework)

3) Go programming language and database operation

4), blockchain 1.0 programming - bitcoin

5), blockchain 2.0 - Ethereum

6), Star Cloud chain and EOS development practice

7), blockchain 3.0 - fabric of super ledger

to you who are still struggling in the tuyere of blockchain: there is a market when there is demand, and the society never lacks excellent technical talents, After a good understanding (you can refer to Qianfeng's blockchain video tutorial), you must be firm and accurate

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.

Now the most popular is the blockchain. Now people continue to join the blockchain instry. Even some giant enterprises are also studying the blockchain. Some people say that the blockchain is a fraud, and others say that the blockchain is the hope of the future. Let's explain it

1. Is blockchain a Ponzi scheme

No, blockchain is a technology. Technology itself can't commit a crime without self-consciousness

blockchain is essentially a decentralized accounting system

What is decentralization? Take chestnuts for example:

in Guaizi village, Cuihua has an affair with Lao Wang next door and is seen by Li Si. After that, Li Si told everyone in the village about it. As a result, Cuihua and Lao Wang Dao are well-known about the affair. For more details, please click

6. Jinwowo, Chongqing: artificial intelligence has the ability to analyze massive data at high speed. As the basis of artificial intelligence, data must be accurate and safe, and there must be no forged data
if the blockchain technology is used, the authenticity and security of data can be guaranteed
by combining the two, consciousness chain forms a data pool, creates an efficient data exchange center, and finally constructs a three-dimensional and multi-functional artificial intelligence ecosystem.

7. tolerable. The police have Internet experts. Besides, if you are cheated, you can only call the police and ask for their help. Personal point of view, for reference only.

8. I believe many people hope to do some part-time work at home to increase their income, especially Baoma. They hope to earn some money at home to subsidize their families. Today I share some of my online part-time jobs
1. Network experience (the one with the most income in my part-time job at present)
many people don't understand how to make money from network experience. In fact, it's very simple. You can register and open an account, and then you can collect some pictures and texts online and publish them. I'm just carrying them. I don't need to think about what to write, just them all, More time may be spent looking for material. How to find, official account and other non network series can be, of course, many will decide that no original, no gains, never mind, you insist.

compared with the current income at the beginning,
it may be a few cents at the beginning. With the increase of the number and level, the income also increases. I have three accounts for more than a year, and now I have experienced the highest level of Dashen Lv2. With a fixed income of more than 10 yuan per day, plus red envelopes, good pen farming and other subsidies, I can add up to more than 1000 yuan a month. Before that, I had to punch in, I can earn more than 2000 yuan a month, but now it's less. Basically, I talk for more than an hour every day, and I send 5 articles to each number, with a total of about 15 articles. It's relatively easier<

the subsidy for clocking is gone
2. E-commerce platforms take orders
for goods taken on e-commerce platforms (mainly: Taobao, Jingdong, pinoo, etc.), sellers will give commissions or small gifts such as data lines, paper towels, umbrellas and so on. I usually add business cards shared by everyone in the group, and some of them will give you tasks, Accumulated for a period of time, there are fixed businesses looking for you. Now I have fixed those shops to do tasks every month to earn some small gifts and commissions. Generally, I earn about 100 yuan a month. If you have enough leisure, you can do more. A friend of mine, Bao Ma, said that he could earn more than 600 yuan a month with three titles. What leisure and perseverance he had
anyway, I can't stand the comparison of goods and screenshots operated by Xiao, which wastes my time. However, students and Baoma are the main force in the group. Generally, this is more suitable for idle people, but novices should also pay attention to fraud prevention. Generally, shops have margin and sales volume, and it's basically OK to shoot physical goods. Many businesses return immediately, and the seller is the vulnerable group

3, Taobao customer commission
many people do Taobao customers will establish a website or group to promote, I believe many people will be pulled into the coupon group, Business Internal group and so on, this is what they promote to earn commission. Ordinary people can not maintain the group, or help friends to buy or their own shopping to earn some commission, save money is more practical. I usually recommend procts that I think are good to my friends. It's OK to help them earn some commission, and it's also hard to earn a lot of pocket money to help friends, relatives and neighbors buy on their behalf
4. Information reading software
now many information apps have been launched to exchange points for money by reading articles. I have tried more than ten apps, and many one yuan tasks are easier to complete. Then I basically rely on apprentices to earn points to earn rewards. I can't earn much money by reading on my own every month. I have tried more than ten apps on four micro signals, and basically I earn rewards for apprentices, I earned more than 100 yuan in two days, no

9. No. Now the communication instry is developed, but personal information leakage is serious. It's normal to have such worries, which shows that people's self-protection awareness has improved. But the proct source chain is a high-tech, using the blockchain encryption technology, will completely encrypt the user's personal information, protect the security of the user's personal information, so, don't worry about this.
