1. Block chain technology is considered to be the fifth core technology most likely to lead to disruptive revolution. After the stage of chaos and bubble period, with the intervention of national policies and the implementation of relevant supervision, +B39 will graally take the lead and develop in a healthy direction.
in 2017, blockchain became the focus all over the world. If at the beginning, the emergence of blockchain made people in the instry excited, and the ordinary people took an indifferent attitude and just ate melon Road, now it can be said that blockchain has quickly and deeply entered the public field of vision
the concept of blockchain was proposed by Nakamoto in 2008. It has the characteristics of decentralization, non tampering, traceability and so on, attracting many investors to participate in it. Blockchain has graally entered into various instries, which has brought considerable changes as well as some adverse effects
through the collection and collation of relevant data of China's blockchain instry, analysts analyzed and discussed the development trend of China's blockchain instry. The rising trend of blockchain popularity is obvious. From the network index trend chart of blockchain and digital currency in the past six months, it can be seen that the popularity of blockchain only increases, and even rises explosively by the end of 2017. According to the trend chart, it can be predicted that the growth of blockchain network index will show a gentle trend in the near future
the network index of digital currency closely related to blockchain is not much different from that of blockchain before 2018. That's because the popularity of blockchain ignites the value of bitcoin, and many people take the opportunity to follow suit, which makes the market once chaotic. Since the beginning of 2018, the network index of blockchain has far exceeded that of digital currency. This change shows that more people are focusing on blockchain, which will be more concive to the healthy development of blockchain technology
as the value of digital currency represented by bitcoin doubled, ICO came into being. ICO financing mode is similar to and different from the traditional IPO Financing Mode. It can open the global market and get more development opportunities. However, e to many people's ulterior motives and the fact that ICO does not go through any strict review process at present, the ICO market is in chaos. The positive and negative effects of ICO also make various countries hold different attitudes in the face of this mixed market
according to the attitude information table of some countries towards ICO, China and Japan have the most clear attitude. China has banned ICO projects and defined them as illegal financing; Japan allows ICO projects and takes the lead in establishing blockchain alliance; The Philippines, Russia, Canada and other countries adopt the mode of supervision and development, do not prohibit ICO projects, and actively build regulatory systems. The United States is a federal country, and the attitude of each state is different
it is worth mentioning that the attitude of Hong Kong and Macao of China towards ICO coincides with that of the mainland, while that of Taiwan is quite different. The person in charge of "Taiwan financial regulatory authority" promised to adopt a more friendly attitude and support enterprises to develop and adopt cryptocurrency and blockchain technology in Taiwan
the top 10 national blockchain platforms are mainly concentrated in Beijing, Shanghai and Guangzhou
according to the national blockchain platform TOP10, bitmainland, Babbitt / blockyuan and fire coin net have taken the top three positions. The blockchain platforms of TOP10 are mainly concentrated in Beijing, most of which were launched earlier than 2016. Generally speaking, the development of blockchain has driven the development of related instries, and also set off a wave of entrepreneurship
the enterprises related to blockchain are mainly concentrated in Beijing, Shanghai and Guangdong, which are affected by the high barriers of blockchain technology. Beijing is rich in human resources and has a good entrepreneurial environment. Shanghai has a unique financial position and has the greatest possibility of incubating the most successful enterprises in the application of blockchain. Guangdong has a strong entrepreneurial atmosphere, which can attract relevant entrepreneurs and promote the landing of relevant enterprises. In addition, Hangzhou also benefited from its excellent Internet finance instry, and the blockchain instry performed well. With the development of blockchain, there will be more related enterprises in more cities< The heat of br/> block chain has also been reced, and a large number of official account have been generated. From the TOP10 official account of WeChat, we can see that the number one fan of "digital money trend maniac" has been estimated to be about 800000 in the past seven days, and second "Wang Chai block chain journal" predicted that the active fans are also close to 500 thousand people. The estimated number of fans who are close to 400 thousand is "third". The official account also shows that more and more people are paying attention to the block chain instry.
blockchain is becoming more and more popular. The average salary of related posts was 23800 yuan before November 2017, and it has reached 25800 yuan by 2018. According to the chart of skills requirements for blockchain positions, the most important is the commonly used development languages (go, C + +, Java). In addition, we also need to have sufficient understanding of cryptography, formula algorithm, and smart contract. In addition, there are also positions with relatively low operation threshold. In general, the talent gap in the blockchain instry is relatively large< Br/> block chain technology is considered to be the fifth core technology most likely to trigger disruptive revolution. After the stage of chaos and bubble period, with the intervention of national policies and the implementation of relevant regulation, it will graally take the right track and develop towards health. The development of br/> block chains will inevitably proce bubbles, but these bubbles will graally become controllable with the healthy development of block chains. The development prospects of block chains and the innovations they can bring are unpredictable. In the future, let's leave this stage to it and watch its performance< br/>

2. Analysis of the application of blockchain Technology. Although theoretically any instry related to digital network can be applied, from the perspective of landing cost, the following instries are more suitable for blockchain technology
as the essence of blockchain is a distributed accounting book, digital currency represented by bitcoin and Ethereum is also a very simple and safe settlement method. In the financial field, the most important process is bookkeeping and clearing. Through blockchain technology, the efficiency of traditional banks and financial instry can be greatly improved
however, all of the above also play the basic functions of blockchain, and there is still much room for improvement. At present, there is no mature blockchain financial project in the world, and we still have a long way to go
when it comes to the application of blockchain, the first thing we think about is the banking and financial instry. Because the essence of blockchain is a distributed accounting system, it is most suitable for the financial instry. The digital currency based on blockchain can also be applied to transactions, clearing and settlement. The security and decentralization of blockchain can ensure the security of bookkeeping. At present, major countries are exploring this application
in addition, many businesses of government agencies are also very suitable for the application of blockchain technology, such as the management of resident identity information, ownership records and proct supervision, etc. Through distributed tamper proof records to ensure the security and privacy of key information. Ireland and many other countries have incorporated this development plan into their short-term goals, which is also one of the more common application areas of blockchain
financial sector: in addition to bitcoin, the financial sector is the most widely used sector of blockchain. After all, financial development is also mixed with money and digital money. In particular, the development of digital currency in recent two years has also driven the application of blockchain
when blockchain spoofing was just emerging, it was questioned by many people and was called blockchain spoofing. Now the chief economists of all countries in the region have begun to abstain from studying the blockchain, proving that the blockchain is graally accepted by the public
in addition, e to the emergence of Ethereum contract, blockchain can also better assist resource sharing related instries, such as our common bike sharing procts. For another example, in the medical field, we can also use blockchain technology to improve efficiency and security, which is a qualitative change in this instry
I believe you have a preliminary understanding of the practical application of blockchain. Looking back at the recent ICO fever in China, a large number of unreliable projects such as dog chain are forced to speculate. Obviously, domestic investors do not know enough about the application field of blockchain. Therefore, stopping ICO not only standardizes the instry, but also protects the investing public.

3. There are two kinds of blockchain analysis reports, one is the rating report, the other is the tracking report. The basic sections include four parts: basic project information, team situation, social media situation, technology progress and market trend. The only difference is that the evaluation report will give the project score, such as cannon rating, and the tracking report will take the long-term tracking method for continuous attention. For example, the first-class position will be analyzed by two shifts a week.
4. A timestamp, usually a sequence of characters, uniquely identifies the time of a moment. Digital time stamp technology is a variant of digital signature technology. In the blockchain, timestamp means that whatever happens at a certain time will be recorded on the blockchain.
5. Search "blockchain" on HowNet to find model articles in this respect.
6. To understand the principle of blockchain thoroughly, we must understand it systematically from its birth and development, so as to distinguish the principle of blockchain more clearly from multiple perspectives. Block chain technology refers to the technical solution of collective maintenance of a reliable database in a centralized way in the past. In this technical scheme, blocks are associated by cryptography. Each data block contains all the data information of the system in a certain period of time, and generates a digital signature to verify the validity of the information, and links to the next data block to form a main chain< br />
Block is a record in the blockchain, which contains and confirms the transactions to be processed< br />
mining refers to the formation of new blocks through calculation. It is a process in which the supporters of the transaction use their own computer hardware to do mathematical calculation for the network to confirm the transaction and improve the security. Take bitcoin as an example: the transaction supporter (miner) runs bitcoin software on the computer and constantly calculates the complex cryptography problems provided by the software to ensure the transaction. As a reward for their service, miners can get the Commission included in the transaction they confirm, as well as the newly created bitcoin< br />
Peer to peer network is a system that allows a single node to interact directly with other nodes, so that the whole system can operate like an organized collective. Take bitcoin: the network is built in such a way that each user is spreading the transactions of other users. And importantly, banks or other financial institutions are not required as third parties< br />
Hash is a classical technology in cryptography, which transforms the input of any length into the output of fixed length composed of letters and numbers through Hassi algorithm< br />
Digital signature is a mathematical mechanism that allows people to prove ownership< br />
Private key is a secret data block that proves that you have the right to consume e-money from a specific wallet. It is realized by digital signature< br />
Dual consumption refers to the user's illegal attempt to pay e-money to two different payees at the same time, which is one of the biggest risks of e-money< br />

The origin of blockchain: an underlying technology supporting bitcoin
The concept of blockchain was first proposed in bitcoin: a peer-to-peer electronic cash system by Satoshi Nakamoto in late 2008. In this paper, block chain technology is the basic technology to build bitcoin data structure and transaction information encryption transmission, which realizes the mining and transaction of bitcoin. Nakamoto believes that: first, the mode of using third-party organizations to process information has the inherent weakness of lack of trust between points. In order to guard against their customers, businesses will ask customers for completely unnecessary information, but still can not avoid certain fraud; Second, the existence of intermediaries increases the transaction cost and limits the practical minimum transaction scale; Third, digital signature itself can solve the problem of e-money identity. If the third party support is needed to prevent double consumption, the system will lose value. Based on the above three existing problems, Nakamoto Cong has created bitcoin on the basis of blockchain technology< br />
On January 3, 2009, Nakamoto proced the first bitcoin block in the world, genesis block, and excavated 50 bitcoins< br />
On May 21, 2010, Florida programmers bought $25 worth of pizza coupons with 10000 bitcoin, which gave birth to the first fair exchange rate of bitcoin< br />
In July 2010, the first bitcoin platform was established, with a surge in new users and prices< br />
In February 2011, the price of bitcoin reached US $1 for the first time. Since then, exchange trading platforms with British pound, Brazilian real and Polish zloty have opened< br />
In 2012, ripple released that as a digital currency, it uses blockchain to transfer foreign exchange of various countries< br />
In 2013, bitcoin soared. The U.S. Treasury Department has issued the regulations on the personal management of virtual currency to clarify the definition of virtual currency for the first time< br />
In 2014, the mining machinery instry chain represented by China became more and more mature. In the same year, the U.S. it community realized the cross era innovation significance of blockchain in the digital field< br />
In 2015, the US Nasdaq Stock Exchange launched LINQ, a digital ledger technology based on blockchain, to record trading and issue stocks
the principle of blockchain can be understood clearly from each application case, and the application of blockchain principle is becoming more and more popular. Recently, Citigroup, Mitsubishi UFJ Financial Group, UBS and Deutsche Bank will also apply "blockchain" technology to build a fast, convenient and efficient blockchain Low cost trading system. In addition to the financial field, blockchain technology has also begun to be applied to the protection of intellectual property rights, notarization by lawyers, online games and other fields where there is a need for transparent information disclosure and permanent records.
