Mardan blockchain
besides today's vpay, I'm not going to talk about it. I just want to explain my own point of view. I've also heard people tell me about the "V" faction. I just want to ask the great gods a question: it's good to share the economy, it's good to return cash from consumption, it's good to return points from consumption, and it's good to exchange points for goods. This is what we have in China. Do you say that if we don't know what country we have, how can we Chinese people get less good things from China? Please think about a problem for investors. MLM sellers never admit that they are MLM sellers. Watermelon sellers never say that their watermelons are not sweet, that their mothers are ugly, that dogs are poor, that their children are incompetent, and that is a treasure in their hearts. So what you choose is always good
let's not say whether it is good or not, but consider one question first. What's returned to you from v-pie consumption is money! Or virtual currency? It's indisputable that we have to make it clear. Then, does virtual currency need to be joined by later generations to purchase virtual currency in order to realize circulation? The result must be! Let's suppose a question, if there are 1.6 billion people in China, and everyone has bought virtual money, (realize your dream, all agree with this thing) 1.6 billion people have used v-pie, what is the result? As a result, when you have virtual currency, do you still need virtual currency? Can virtual currency replace RMB in shopping? If you have virtual currency, who do you sell it to? Is virtual money real money
if there are only 100000 people in China who will use it again, and these people will not use it in the future, what about the virtual currency of 100000 people? Can it be realized? In the end, once no one goes in, the result will come out, rich in figures and poor in grandfather Mao
before that, there was an apple growing model - 27822; I don't know how many people have participated in the game. What the Chinese say is too extravagant to be true. Foreign dog poop may be more expensive than jewelry as long as it comes to China. Early is also to buy apple trees, apple trees will bear apples, an apple a dollar, how many apples can be exchanged for an apple tree. A series of figures, we just think that the more trees I plant, the more apples I receive, and the more I earn. We always ignore the problem that if you don't find someone to sell the apples to, if no one does, don't plant the apples. I'll give you the apples directly. Question: how can you cash your apple? I just want to make money, but I don't want to know where the money comes from
vpai is just a virtual currency, which does not represent RMB. Now it can be traded only by pulling the head. Once there is no head, it is all virtual currency. You feel like no matter how rich you are, no one will recycle your money. Just like those apple tree growers, how about taking tens of thousands of apples a day with their account number? Who can you sell them to? Can you eat them? Who will recycle it in the end? It's still a new person who depends on development. Without RMB, those are nothing.
Three questions blockchain (economic hot spot)
recently, news about bitcoin is very eye-catching, and blockchain is on fire. In the capital market, the rise and fall of various blockchain concept stocks is like a roller coaster. It can be seen from the sensitive capital market that the blockchain is on the way and is highly concerned by all parties
"blockchain technology is essentially a kind of database technology, specifically a kind of ledger technology. The account book records the asset changes and transactions of one or more accounts. In fact, it is a kind of database with the simplest structure. The daily accounts we usually record in the small account book and the statements sent by the bank are typical account books. " Wang Jun, chief researcher of Tencent Financial technology think tank, said that security is a major feature of blockchain technology, which is mainly reflected in two aspects: one is the distributed storage architecture. The more nodes there are, the higher the security of data storage is; The other is the ingenious design of tamper proof and decentralization, which makes it difficult for anyone to modify data without following the rules
take the online shopping transaction as an example, the traditional mode is that the buyer purchases the goods, and then sends the money to the intermediary platform of the third-party payment institution. After the seller delivers the goods and the buyer confirms the receipt, the buyer informs the payment institution to send the money to the seller's account. The transaction mode supported by blockchain technology is different. Buyers and sellers can trade directly without any intermediary platform. After the transaction between the buyer and the seller, the system publishes the transaction information in the form of broadcast, and all hosts receiving the information record the transaction after confirming that the information is correct, which means that all hosts have done data backup for the transaction. Even if a machine has problems in the future, it will not affect the data recording, because there are countless machines as backup
when it comes to blockchain, many people associate it with bitcoin, and many even equate blockchain with bitcoin. He Fei said that bitcoin is a way of presenting blockchain, but blockchain is not the same as bitcoin. Blockchain is the underlying technology and infrastructure of bitcoin, and bitcoin is a successful application of blockchain, but it does not mean that blockchain can only be applied to bitcoin
What is the use ofblockchain
can solve the pain points and difficulties in many fields such as finance, public welfare, supervision, anti-counterfeiting, but there are many applicable conditions
financial service is the first application field of blockchain technology. The application of blockchain technology can solve the pain points in payment, asset management, securities and other fields
taking the payment field as an example, the cost of reconciliation, clearing and settlement among financial institutions, especially cross-border financial institutions, is high, involving many manual processes, which not only leads to high costs for users and financial institutions' back-end business, but also makes it difficult to develop micro payment business. The application of blockchain technology helps to rece the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing efficiency of payment business. In addition, the cost and efficiency advantages brought by blockchain technology in the field of payment enable financial institutions to better handle the small cross-border payment which was considered unrealistic e to high cost in the past, and contribute to the realization of Inclusive Finance
for example, in order to solve the problem of high reconciliation cost among financial institutions, in August 2016, Weizhong bank and Shanghai Huarui Bank launched the inter agency reconciliation platform of micro loan, which is also the first application scenario of banking alliance chain running in the proction environment in China. Zhang Kaixiang, chief architect of Weizhong bank's blockchain, believes that the high cost problem that the traditional "batch file reconciliation" model has failed to solve for a long time is exactly where blockchain technology can be used. Subsequently, Bank of Luoyang and Bank of Changsha have also been connected to the inter agency reconciliation platform. Through the blockchain technology, the inter agency reconciliation process in the micro loan business has been optimized, achieving the goals of quasi real-time reconciliation, improving operation efficiency and recing operation cost. Up to now, the platform has been running stably for more than one year, with zero failure, and the number of real transactions recorded has reached tens of millions
in the field of public welfare, blockchain technology is also promising. The first application scenario of ant financial services involving blockchain is public welfare, which helps a group of hearing-impaired children get a donation, and then uses blockchain technology to promote public welfare to be more open and transparent. Hu Danqing, senior proct expert of ant financial services technology laboratory, said: "the blockchain public welfare platform is like a post office dedicated to mailing funds on the Internet. Every sum of money donated by users will be packaged into a package, which will be delivered through the blockchain platform. Every node we pass through will be stamped with a postmark and finally delivered to the recipient. This can ensure that every sum of money donated by users is transparent, traceable and difficult to tamper with. "
blockchain technology can be used to crack down on counterfeit goods. Hu Danqing introced that ant financial services has applied blockchain technology to the traceability of authentic procts. At present, some seafood procts from Australia and New Zealand, such as milk powder, are swept away with Alipay, so they can know if they are genuine procts. Different from previous businesses' self input of commodity information, blockchain allows multiple "bookkeepers" to complete bookkeeping fairly, independently and non repudiately. "
for financial supervision, blockchain technology can also play a role. According to the white paper of FISCO bcos, the underlying platform of financial blockchain, issued by the financial blockchain cooperation alliance (Shenzhen) in 2017, blockchain provides consistent and easy to audit data for financial regulators. Through the data analysis of inter agency blockchain, it can supervise financial business faster and more accurately than the traditional audit process. For example, in the anti money laundering scenario, the balance and transaction records of each account are traceable, and any link of any transaction will not be separated from the regulatory line of sight, which will greatly improve the anti money laundering efforts
some people in the instry believe that blockchain 1.0 is mainly aimed at digital currency; Blockchain 2.0 aims at smart contracts and can be applied in financial markets; Blockchain 3.0 will apply to more scenarios, and even create a "blockchain era"
He Fei believes that blockchain can indeed solve the pain points and difficulties in many fields, but blockchain is not omnipotent and has many applicable conditions
for example, the decentralization of blockchain technology is suitable for multi-party participation scenarios, and if it is only unilateral or bilateral participation, the value is not great. Due to the need for each node to check, blockchain technology is not suitable for those high-frequency trading activities
for another example, blockchain emphasizes openness and transparency, which is not suitable for scenarios with high data privacy requirements
will blockchain become a new outlet
technology is not yet mature enough. We must be alert to the concept of speculation. In particular, we should distinguish between technological innovation or fund-raising innovation. We can not block the chain chain concept of
block chain so that we will not become a "Internet plus". p>
in recent years, the development ecology of blockchain has been graally improved and enriched. Instry insiders believe that with national policy support, extensive attention and financial support, blockchain technology can achieve graal and stable progress. Although the prospect of blockchain technology is broad, we should also keep an ordinary mind
"despite the current blockchain craze, we still believe that it is still in a very early stage." Hu Danqing said that at present, there is a virtual heat in the concept of blockchain. Instead of using technology to solve practical problems, it is hot to raise money and speculate on valuation. In particular, most of the so-called ICO (initial token issuance) that are hot are innovation of fund-raising tools, which has nothing to do with technological innovation
blockchain technology can indeed create great value, but some risks can not be ignored
"blockchain technology is not very mature, and its application scenarios are relatively limited, so we should be more alert to the concept of capital market speculation." He Fei said that behind the blockchain boom, there will inevitably be some companies that want to speculate. They do not really carry out business, but just try to make a profit in the capital market. They should be careful to prevent the emergence of "bad money drives out good money", which will lead to the withdrawal of institutions that really want to carry out business from the market and affect the application of blockchain technology
Hu Danqing suggested that for the current blockchain craze, regulatory authorities should be more active in intervening, distinguish between technological innovation and fund-raising innovation, encourage government organizations, credible experts and instry participants to help the public identify, comprehensively curb fund-raising innovation in the name of blockchain, and let the actual controller of ICO bear responsibility for fund-raising behavior“ The basis for judging whether it is technological innovation or fund-raising innovation is actually very clear, that is, whether it starts with trust and whether it creates practical value by solving the trust problem. "
in order to better promote and use blockchain technology in the future, we need to continue to improve the infrastructure and strengthen the formulation of relevant laws and policies
Wang Jun believes that there is still room for optimization and improvement of core technologies of blockchain such as consensus algorithm; On the other hand, the processing efficiency of blockchain is difficult to meet the requirements of some high-frequency application environments in reality. At present, the mainstream blockchain technology platforms are originated in foreign countries. Domestic blockchain technology service providers should patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the development of global blockchain technology. Enterprises with blockchain application scenarios should actively embrace new things and scientifically evaluate the demand for blockchain, instead of blockchain for the sake of blockchainHe Fei believes that the government can issue relevant policies to guide the enterprises who are interested in the R & D and application of blockchain technology, and at the same time, clarify some suitable application scenarios of blockchain and areas encouraged by the state
the white paper 2016 on the development of China's blockchain technology and application suggests that government departments at all levels should learn from the advanced practices of developed countries and regions and, in combination with the development of China's blockchain technology and application, timely issue support policies for blockchain technology and instrial development, focusing on supporting key technology tackling, major demonstration projects, the construction of "innovation and entrepreneurship" platform, and the development of China's blockchain technology and application System solution development and public service platform construction. At the same time, it is suggested that domestic key enterprises, scientific research institutions, universities and user units should strengthen cooperation to speed up the research of core key technologies such as consensus mechanism, programmable contract, distributed storage and digital signature
can bring money to the enterprise will become the outlet
Chinese Mahjong: the world's earliest blockchain project
first of all, a initiates an application. I want to play mahjong and set up a mahjong Bureau, which is equivalent to creating a block, and this block will be broadcast to B, C, D, a, B, C, C, C, C, C, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D D...
in the process of playing mahjong, the above four people constantly play cards, which can be understood as mining, through what to mine? Mahjong machine can understand the mineralization machine. These four miners are the so-called miners. These four miners collide from 144 mahjong, and any right card can be Hu card. We can understand the 144 mahjong as a series of hash values (numbers). The process of Hu card is called computational power. Until Hu card, it means that the right hash value is collided and you can get a reward, Each person will pay the corresponding chips to C and put them in the blockchain. The reward is bitcoin or other virtual coins
Why do the other three people take the initiative to reward C? That's because these people have automatically reached a consensus that C has indeed won, and everyone has recorded the account, including the family members who are sitting next to buy horses. It's not good to deny it, otherwise when it comes out that the character is not good, no one will play with him again. After all, the circle is very important
when we reached a consensus, we didn't see any intermediary or third party judging that C had won, and the rewards given to C didn't need to be transferred to C through the third party. All of them were direct point-to-point transactions. This process was decentralization. The card players (miners) recorded their own achievements in the first game, and the third team won the first game, After the record is completed, a complete block is generated. But remember, this is only the first round. In the whole blockchain, this is just a node. The first eight rounds are finished, that is, eight nodes (blocks). Eight blocks are connected together to form a complete account book, which is the blockchain. Because everyone has one account book, it is a distributed account book. The purpose is to prevent someone from tampering with records. In the end, it is clear who wins or loses.
to get down to business, let me analyze the routine of media platform from the perspective of media. A company needs a certain public opinion environment when it needs to develop, especially in emerging instries. What kind of things will media do for emerging instries? They will publish false reports and even malicious remarks about the instry. It's often the work of small media companies, so why do they do it? It's very simple to earn traffic. The most eye-catching is often the heated comments. This kind of articles can easily incite netizens' emotions and increase their reading volume. In this way, the flow of cash is a very simple thing, then the capital of advertising will become higher. The more vertical reports the article has, the more valuable the vertical ads will be. For example, if I am a we media practitioner and I have been making untrue comments about the blockchain instry, then one day a blockchain company wants to send a report to me, then I can ask for a price
most of the untrue comments on the Internet can be divided into several categories: the spread of falsehoods between small websites and small media. Rumors start from taking out of context and making up, and then they will be further upgraded. The first wave of taking out of context and making up articles will be used to intercept part of the evidence to spread the upgraded version of rumors. When many stars or company leaders see this, their first reaction is: when did I say this&# 160; The second reaction is to laugh. The media, alas, is normal. More helpless, spend money to find the media to explain it, another group of people said you wash white. Don't make a statement and say you acquiesce. This vicious circle wave after wave, some companies are not so destroyed? In view of the above content, I give the questioner a clear way to distinguish, first: pay attention to check the level of the media that issued the article, and be happy with what the small media say, but don't take it seriously. Second: is it released from its official platform? If not, no one knows so much inside information
from the perspective of technology, what's wrong with blockchain technology? It's just an emerging technology. In fact, it can't be counted. It was first applied to bitcoin. It's just that there is a delay for the general public to come into contact with these, just as it will take a few years for the routine model of big cities to develop into small cities. Columbus cat does have a certain strength in the technical circle, and its technical reserves are quite sufficient. Just want to achieve comprehensive business development, it will certainly need a long march. For example, we may have developed the online payment system long before Taobao came out, but the technology can not be applied immediately. First of all, you have to convince others to believe you, so that you can really apply it. Father Ma succeeded in persuading Chinese women, so he succeeded. Blockchain itself is a cross era technology. To better promote it, more dedicated entrepreneurs need to work together.
How to identify illegal gangs is a very important skill in the Internet age. To identify whether an organization on the network is an illegal organization, you only need to identify whether it has a certain threshold fee to know
but this is only for technical talents or engineers. For ordinary people, it is not easy to use and transparent as many other unknown network procts or technical pronouns. It needs considerable technical threshold in use. As a new thing, network has developed for many years. However, e to the development of the network to the practical stage, it is only a few decades. For the Chinese people, it is still a relatively new thing. A lot of traditional deception can be packaged through the network, just for a vest, still can cheat a lot of people. Especially for the elderly. After the use of network tools, the amount of information received is greatly increased, at the same time, there will be a greater chance to come into contact with these cheating illegal groups. Just remember one principle at this time. Any project investment activities that need to be paid are all deceptive. I hope everyone can protect themselves and their families in the online world
now the rapid growth of computer technology, every company needs computer talents, you can go to learn computer professional,
there is still a lot of development space in this field, as long as you study hard, the future prospects are unlimited.
