1. blockchain is a kind of technology. "In the simplest and most popular way, blockchain technology is everyone bookkeeping, or distributed ledger."
in the Internet era, there is a database behind every system. This database can be regarded as a large account book. In the past, the person who maintained the system was responsible for managing the database and recording the user's behavior, that is, bookkeeping. However, the blockchain is "decentralized", which allows every member of the system to participate in it, not only everyone bookkeeping, but also through links, Everyone can have a complete account book
"blockchain is essentially a collective recording mode. What's special is that it adopts a set of techniques in an ingenious way to realize the authenticity and credibility of the recorded results, which is difficult to destroy and tamper with. " Zhang Xiaorong said, "first, everyone has the right to record and authenticate with each other to distinguish the true from the false, which is called consensus mechanism; Second, no one can tamper with the records, because there are cryptographic signatures; Third, everyone has a , so even if some account books are damaged, the whole will not be affected. This is called distributed storage. The information recorded in this way is presented in block mode according to the time chain, so it is called blockchain. "
various cryptocurrencies represented by bitcoin are originally an application of blockchain technology, which can be described as blockchain version 1.0. However, around 2014, the instry began to realize the important value of blockchain technology. Blockchain graally separated from digital currency and applied to various economic and social fields other than digital currency
it has broad application prospects
blockchain technology is considered as a disruptive innovation after steam engine, electric power and Internet. If the steam engine and electricity liberate the proctivity, and the Internet has changed the way of information transmission, the blockchain, as a machine for building trust, may change the way of value transmission
for example, in the financial field, the cost of reconciliation, clearing and settlement between financial institutions, especially cross-border financial institutions, has always been very high, and there are complex manual processes. The application of blockchain technology can help rece the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing speed and efficiency of payment business, It also makes small cross-border payments possible. In December 2017, China Merchants Bank completed the RMB position transfer business from Hongkong Wing Lung Bank to Shenzhen Branch of Wing Lung Bank. This is the world's first interbank cross-border RMB clearing business based on blockchain technology
in addition, according to the white paper 2016 on China's blockchain technology and application development issued by the Ministry of instry and information technology of China, the application of blockchain has been extended to medical and health, ecation, charity, social management and other fields. Taking the cultural instry as an example, the low cost of reproction, the high cost of safeguarding rights, and the difficulty of providing evidence make the protection of intellectual property rights a pain point for the instry. With blockchain, the proction, dissemination and transaction records of cultural procts are true, transparent and reliable, and the problem can be solved
Zhang Xiaorong said that blockchain technology has solved two major problems in the era of Digital Economy: one is the visible flow direction, and the other is zero trust cost. In the past, the circulation of physical paper money was invisible, but the flow of all digital assets had a "chain" to check. Yang Yanchao, a researcher at the intellectual property center of the Chinese Academy of Social Sciences, also believes that the biggest advantage of blockchain is that it has truly completed the credit construction in an anonymous society, bringing new opportunities to many fields, thus making various innovative applications possible
there is a long way to go in the future development
in terms of technology promotion, there is no big barrier to blockchain, which has been confirmed in the global practice of bitcoin, and its main resistance comes from the obstacles in concept and implementation
"on the one hand, the society may be very concerned about the" naked "state in the blockchain. Blockchain has built a "Skynet" for the commercial society. The company's economic activities are all recorded, so there is no secret to speak of. In this way, some business strategies may not be implemented under the blockchain. "
"on the other hand, the current legal system lags behind the development of information technology, so how to put the emerging blockchain technology under the legal supervision needs to be studied." Duan Yongchao said
the core of blockchain is decentralization, which will have an impact on the long-standing central management model. In addition to the law, how to establish a regulatory environment that can promote the application of blockchain technology, so that the technology can benefit the society and not be used to do evil, is also an urgent problem to be solved.

2. virtual currency is a kind of blockchain technology. Some countries are legal, such as Japan, Russia, South Korea, etc. 66otc is currently the most fluent, reliable and best used OTC platform
3. Blockchain is a key project in the 13th five year plan for national informatization. It is parallel with artificial intelligence, big data, driverless and other projects. With the support of the government, blockchain technology has developed rapidly, and China's blockchain instry is expected to take the lead in the world. At present, the number of domestic blockchain related companies is increasing, of which fast online has been in the lead
4. Blockchain and artificial intelligence will become the future of the peerless double pride
we need to change and innovate in the present era, and blockchain, artificial intelligence and new retail are the procts of the era innovation which has been popular in recent years, which makes us proud and proud. Blockchain and artificial intelligence have become the two most discussed concepts in 2018. Blockchain and artificial intelligence have loyal followers in various instries. Which technology can better represent the future development direction of science and technology
in the past year, blockchain, an epoch-making technology, has come into the public eye. It is considered to be the most likely technology to bring about disruptive changes, and is warmly sought after by venture capital and capital with keen sense of smell
whether Alfa dog wins the world champion of weiqi, the opening of private supermarket or the driving of automatic driving cars, artificial intelligence has become the main character of daily news. With Google announcing the establishment of AI China Center in China, the development of artificial intelligence has been written into the government work report. Today, China has become the main role of the world's artificial intelligence instry. 2017 is a wonderful year, known as the "first year of application" of blockchain and artificial intelligence. It can be predicted that in 2018, blockchain and artificial intelligence will still stand in the air and receive high attention from all parties
What are blockchain and artificial intelligence? Blockchain is a kind of decentralized media, which brings an innovative mode of value storage and circulation. Artificial intelligence makes machines create value like human beings. It is a new system of value creation. Therefore, blockchain represents the future proction relationship, while AI represents the future proctivity. From the hot circle of friends of "three o'clock sleepless blockchain" in the early morning to the extensive elaboration of artificial intelligence and blockchain in the government work report in 2018, these two kinds of cutting-edge technologies that firmly catch people's attention are so different that any attempt to combine them will inevitably arouse the curiosity and doubt of the world
blockchain and blockchain technology are two different circles. We often say that currency circle and chain circle are a common division. Currency circle discusses the growth value of currency, while chain circle discusses pure technology. Therefore, sometimes we say that the concept of blockchain is greater than blockchain technology. In fact, the technology of blockchain is not very difficult. Its technology can be used in many places, but it is its technology that sometimes limits its development. On the contrary, the problem of AI is how to survive with human beings. Artificial intelligence is promoting the progress and development of the times in many aspects, but human society is not really ready to meet the arrival of the era of artificial intelligence, whether in human consciousness, ethics, laws and regulations or social management, there is still a long way to go
with the rapid development of artificial intelligence technology, human beings are forced to develop further and constantly innovate rather than stop.

5. I don't think so. The original God's mine is refreshed frequently, and there are many refresh points, so don't worry about others digging your mine
6. Let's take personal information security as an example, because the disclosure of personal information will cause great harm to informants, making them suffer from conservative harassment. What's more terrible is personal information leakage, which is usually accompanied by tens of thousands of personal information being stolen, illegally sold, and even using the formal data trading institutions to steal data. With the rise of jinwowo blockchain technology, the encryption of blockchain technology can provide solutions for the protection of personal information. Blockchain technology can store personal information in a distributed way to avoid the security risks faced by a single server.
7. When it comes to blockchain, we have to talk about bitcoin. Most people in the market begin to recognize bitcoin through its market influence, because bitcoin was born on the basis of blockchain technology. Blockchain is simply an innovative application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Applying this technology to the transaction of virtual currency can make each transaction proce a corresponding data block, so as to ensure the authenticity of information. The biggest advantage is that it cannot be forged, It solves the trust problem in data transaction environment
of course, as blockchain technology becomes more and more mature and stable, it will be more and more applied in various real instry business scenarios, including finance, social communication, Internet of things, e-commerce, games and securities trading, For example, our project of "intelligent system for ecological chain of structural hole investment and financing" is the first innovative application of this technology in the field of investment and financing. However, from the purely technical level, the main purpose of blockchain is to ensure the safety of data operation, which is the biggest advantage of this technology. So what is the relationship between blockchain technology and virtual currency? Take bitcoin as an example. Bitcoin is a virtual currency based on blockchain technology and proced through a large number of algorithms. Due to its special algorithm and the anti-counterfeiting function of blockchain technology, the total number of bitcoin will remain unchanged at 21 million. It is precisely because things are rare that bitcoin is loved by many people
so why are there a lot of virtual currency scams under the banner of blockchain in the market today? This is because these so-called innovative application companies of blockchain issue virtual currencies. Although they claim that the number of virtual currencies is very limited in the market promotion, and they can make investors earn a price difference by raising the price through currency speculation, in essence, the issuance of their virtual currencies is controlled by their companies and can be changed according to their own wishes and needs, The purpose is to make illegal profits. In the market, many investors who don't know the truth are cheated because they lack the knowledge of financial investment. They are in the spirit of speculation to earn profit. Once they are put in, these so-called virtual currencies will be manipulated by the company in the background, resulting in the loss of money. When investors enter into such a game, they often change from the original intention of speculation to gambling. When they buy at a high price and see that the price continues to fall, they will naturally make up their positions and make additional investment when there is a rebound. In this way, they are repeatedly cleaned up and cut leeks. Finally, they sink deeper and deeper and lose their property. It is precisely because the price is controlled by the company, Therefore, these companies make huge profits, even beyond the imagination of ordinary people. What we want to say about this market phenomenon is that it is not the fault of blockchain technology itself, but that it is caused by some illegal people in the market who stealthily changed the concept, took advantage of people's lack of professional knowledge of blockchain technology and financial investment, and grasped the psychology of greed for wealth< br />
the existence of these black sheep in the market confuses the public and disturbs the market. As a result, the innovative application of business scenarios based on blockchain technology has brought serious practical obstacles to the healthy development of social economy and value creation of entrepreneurial and innovative projects, such as the "structural hole investment and Financing Ecological Chain Intelligent System" project, In fact, it is based on the innovative application of blockchain + AI + OKR and other technologies in the investment and financing ecological business scenario, and redefines the investment and financing business model. The purpose is to provide enabling services for the three groups of project parties, resource providers and investors in the ecological chain to create value and fulfill value transactions, so as to significantly improve the success rate of investment and financing for the three groups of customers, without issuing virtual currency, Without manipulating the price of the virtual money market, it is a good project for the healthy development of the social economy, which is also affected. It is really painful and difficult, but it has nothing to do, and it can only bear the hardships silently. Today's view is: blockchain fraud is guilty, and blockchain technology cannot be innocent.
of course, as blockchain technology becomes more and more mature and stable, it will be more and more applied in various real instry business scenarios, including finance, social communication, Internet of things, e-commerce, games and securities trading, For example, our project of "intelligent system for ecological chain of structural hole investment and financing" is the first innovative application of this technology in the field of investment and financing.

8. This confidential project was restarted many years ago. People were surprised to find that Ma Yun had such advanced blockchain concept 19 years ago< P> learned that before Alipay was invented by the public, Ma Yun was actually the first to launch an international cross-border transaction platform. At that time, the idea of innovation was a technological revolution for them. Ma Yun's original intention was actually very simple. He wanted to make the world have no hard business and make people want to do business all over the world. As long as you open your computer and operate the mouse gently, you can order and deliver goods and successfully complete the transaction. At that time, one of the core issues was cross-border secured transactions. Because there is no reliable technology to support it, it can only be shelved
after the platform went online, the first transaction made was a batch of glass ornaments sold to Mexico. The seller laughed so hard that he received the payment the next day. In an interview, she happily said that this platform has benefited many small and medium-sized enterprises, and cross-border business will become simple and convenient
