Trend chart of attention of blockchain Technology

1. Driven by policy and market, blockchain instry has a bright future
driven by policy and market, China's blockchain related instries are expected to move from virtual to real
in the context of rapid development of blockchain, China should comply with the needs of globalization, keep up with the international pace, and actively promote the research, standardization and instrialization development of domestic blockchain related fields. Compared with the increasingly stringent supervision of bitcoin and other digital currencies, the support and encouragement of blockchain technology has reached a consensus in the world, and the domestic blockchain technology will also receive national and local policy support in the next few years. Driven by policy and market, blockchain related instries are expected to move from virtual to real, and blockchain technology will accelerate the exploration of possible application scenarios< According to the data of the "in depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, the global blockchain market scale is expected to increase from US $411.5 million in 2017 to US $7683.7 million in 2022, with a compound annual growth rate of 79.6%. In view of the wide application range of distributed ledger, the rising market value of cryptocurrency, the strong demand for improving transparency, security, efficiency and simplifying process, and the popularity of blockchain as a service (
baas), the blockchain market will expand rapidly. In addition, communication services, international trade, supply chain management, programming platform, payment, smart contract, digital authentication and so on are also in urgent need of blockchain technology, which will create a lot of growth opportunities
as an integrated application of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other technologies, blockchain has become a research hotspot of the United Nations, the International Monetary Fund and other international organizations as well as many national governments in recent years, and the instry has also increased investment. At present, the application of blockchain has extended to the Internet of things, intelligent manufacturing, supply chain management, digital asset trading and other fields, which will bring new opportunities for the development of cloud computing, big data, mobile Internet and other new generation information technology, and have the ability to trigger a new round of technological innovation and instrial change
by 2022, the payment sector may occupy the largest share of the blockchain market
relying on blockchain technology, real-time payment of assets can be realized, which not only has the characteristics of tamper proof and digital authentication, but also can greatly save the cost of settlement for financial institutions and banks. In addition, blockchain makes payment automation possible, eliminates the need for middlemen, and saves labor costs and time for buyers and sellers. Thanks to the above advantages, it is expected that the payment sector will be the heaviest one in the whole blockchain market
the fastest growing region will be the Asia Pacific region.
blockchain service providers in the Asia Pacific region are good at designing and developing cryptocurrency platforms with friendly interface, cost saving and high speed, and extending the application of blockchain in many instries. Both large enterprises and small and medium-sized enterprises are actively seeking risk financing, investing in and developing the most cutting-edge blockchain technology. In addition, the real estate instry of some countries in the Asia Pacific region is expected to rapidly transform from translucency to full transparency, which also helps to enhance the development prospects of blockchain in the Asia Pacific region.

2. Blockchain is the biggest trend in the next decade
if you look at the problem with the thinking of 30 years ago, you will think that others are crazy, but in fact you are out of date
the concept of blockchain can be traced back to the end of 2008. In the forum, a mysterious personage named "Nakamoto Tsung" published a paper "bitcoin: a peer-to-peer e-cash system" and proposed the concept of blockchain for the first time
on January 3, 2009, the first block of the blockchain was born, which is called the "Founding block"
almost with the birth of blockchain technology, bitcoin became the first thing to play its role. In the following years, bitcoin graally swept the world. In 2017, its crazy market made blockchain technology known to all
the idea of blockchain first appeared in the famous bitcoin open source project. In the process of its birth and development, bitcoin project draws on the technical achievements from digital currency, cryptography, game theory, distributed system, cybernetics and other fields. It can be said that bitcoin project is good at all. As its core supporting structure, blockchain technology is a remarkable innovation achievement
blockchain is a distributed database system with different nodes, which is an open ledger system<
three characteristics of blockchain
compared with the traditional centralized scheme, blockchain technology mainly has the following three characteristics:
the core idea of blockchain is decentralization
in the blockchain system, the rights and obligations between any node are equal, and all nodes have the ability to vote with computing power, Thus, the result recognized by more than half of the nodes is guaranteed. Even under serious hacker attacks, as long as the number of nodes controlled by hackers does not exceed half of the total number of nodes in the world, the system can still operate normally and the data will not be tampered with
block chain's biggest subversive is the establishment of credit
the collective maintenance of blockchain can rece the cost
in the centralized network system, the maintenance and operation of the system depend on the operation and operation of platforms such as data center, and the cost cannot be omitted. Anyone can participate in the nodes of the blockchain. Each node can verify the correctness of the results of other nodes' records while participating in the records, which improves the maintenance efficiency and reces the cost
in a word, blockchain touches money, trust and power, which are the fundamental basis for human survival< Its development has gone through three stages
1. Brewing period: from 2009 to 2012, bitcoin and its instrial ecology are the main economic forms
2. Embryonic period: from 2012 to 2015, with bitcoin entering the public view, new wallet payment and remittance companies appeared, and blockchain economy spread to the financial field. The underlying technology of blockchain is constantly innovated. Blockchain technology is separated from bitcoin system
3. Development period: in 2016, we began to explore instry applications, and a large number of blockchain start-ups appeared. The popularity of ICO in 2017 has given blockchain unprecedented attention
"blockchain 2.0 era" is coming
the application service layer is the driving force for the sustainable development of blockchain, which is divided into three stages of application: 1.0, 2.0 and 3.0
programmable currency: blockchain 1.0 application
programmable currency is the digital currency represented by bitcoin, but it is not the legal tender of any country or region, and there is no government authority to provide guarantee for it
programmable Finance: blockchain 2.0 application& quot; Smart contract& quot; Using program algorithm to replace the concept of contract execution. This enables blockchain to expand from the original monetary system to the registration and transfer of equity, creditor's rights and property rights, the transaction and execution of securities and financial contracts, and even the financial fields of gambling and anti-counterfeiting
programmable Society: blockchain 3.0 application
blockchain is the core of value Internet, which can confirm, measure and store the property rights of information and bytes representing value in each Internet. It can not only record the transactions of the financial instry, but also record almost anything valuable that can be expressed in the form of code. Its application can be extended to any field with demand, and then to the whole society
at present, the application of blockchain has begun to surpass bitcoin (blockchain 1.0), enter the era of blockchain 1.5, and transition to the financial field (blockchain 2.0)
in the next 3-5 years, blockchain may go beyond the financial field and enter the field of social notarization and intelligence (blockchain 3.0), including identity authentication, notarization, arbitration, audit, domain name, logistics, medical care, mail, visa, voting and other fields. Its application scope will be expanded to the whole society, and blockchain technology is likely to become a new technology& quot; All things are connected& quot; It's the lowest level protocol
at present, blockchain technology has been recognized by the world, and its development has become an inevitable trend. Accompanied by more people's attention, "in the next 30 years, new technologies will be integrated into all aspects of traditional instries, and human society will turn upside down. No matter who you are, no matter where you are, all of us will be a part of this great change."
this is the current situation. Blockchain has given the post-90s an opportunity. However, if you want to control blockchain technology without being affected by negative factors, the most important thing is to have a clear understanding of it, whether it is regulators, researchers, speculators or bystanders
it's time to devote more energy to blockchain technology
in China, the average annual salary of blockchain positions has reached more than 300000, and that of some enterprises has reached more than 1 million. The monthly salary of blockchain instry graates in Beijing, Shanghai and other places has exceeded 20K! If the post-90s seize the bonus of the times, they may become the next Alibaba in the future! If you miss it, you may regret it for ten years.

3. The highlights of the global economy range from manufacturing to real estate to Internet to finance, and then from the development of Internet Finance generation by generation to blockchain. I think this may be the last stop. It's like taking a train to the end. There won't be a stop in less than ten years. In 2018, all the suoha blockchain companies want to turn over and make some achievements, I believe this is the only opportunity for you to talk about your dreams again and seize the last opportunity in your life.

4. Wangchain technology uses blockchain technology to record the whole process data of procts from proction to users, so as to ensure that the information is transparent, authentic and tamperable, and realize information sharing in proction and circulation.

5. There is also no fear of death in the bitcoin situation, first of all, the domestic ban has not been allowed to trade, second foreign platforms and prices are not stable, third is likely to become a bubble, coupled with the collapse of foreign countries and then spread to the domestic market has been unpredictable and response, recommended caution.

6.

The sudden epidemic situation has pressed the "pause" button for many instries, but science and technology is the most effective means to fight against disasters. Blockchain technology has realized the combination with finance, logistics, supply chain, government affairs, public welfare, urban management and other application fields. At the same time, e to the imperfect development of technology, the role of blockchain in the prevention and control of the epidemic is very limited, so we need to explore deeper scenario applications

from the survey data, the main application directions of instrial blockchain in the post epidemic period include: traceability, financial (including insurance) supervision, collaborative sharing. Deposit certificate, digitization, credit investigation, digital asset transaction, etc

in the main application direction of instrial blockchain in the post epidemic period, more than 70% of enterprises choose traceability and financial (including insurance) supervision, in addition to collaborative sharing and certificate deposit. Digital also has more than 60% of the enterprise choice, compared with the low choice rate of credit reference and digital asset transaction, in which the choice rate of digital asset transaction is less than 50%, only 48%

to avoid risks and promote the healthy development of instrial blockchain

as an emerging technology development direction and instrial development field, blockchain has been widely concerned. The application of instrial blockchain is accelerating, which is mainly reflected in two aspects:

first, in the past, open source systems were represented in technology, and most of them were open source projects oriented to consumers, but now many projects oriented to instry and enterprise characteristics have been added; At the same time, more and more enterprises such as Internet giants and high-tech enterprises begin to enter this field, indicating that the era of instrial blockchain has come

secondly, the emergence of blockchain reces the threshold of trust and the cost of realization, enabling some financial and trade scenarios that could not be realized before to be realized. In this way, some new financial forms can be derived, providing more space for financial innovation

although the application of instrial blockchain is speeding up, it is still in an early stage of development. This is mainly reflected in the fact that blockchain technology alone can not fully solve the trust problems and information island problems between entities, and the emergence of blockchain technology also puts forward new problems for the current law and regulation

because of its decentralized and difficult to tamper with characteristics, blockchain has become a comprehensive subject driven by technology and deeply affecting economy, finance, society, organizational form and governance. In addition, blockchain technology is not yet fully mature in system stability, application security, business model and other aspects, which puts forward requirements for privacy protection and storage capacity of data on the chain

it should be noted that the current blockchain instry has been involved in many technical fields such as it, communication, security, cryptography and so on. What it needs is a kind of compound talents, which poses new challenges to personnel training and school ecation

the short-term impact of blockchain should be treated calmly to avoid overestimation. At the same time, it is necessary to further strengthen laws and regulations and supervision to avoid the possible risks of blockchain technology, so as to promote the healthy development of instrial blockchain

7. N1 pass 100 points, language knowledge (words, vocabulary, grammar) pass 19 points, reading pass 19 points, listening pass 19 points
the new Japanese language proficiency test is to evaluate whether the students pass the test through the comprehensive score and the passing score of each item. That is to say, the comprehensive score must be above the qualified score, and each single score must be above the passing score set by each single score to be regarded as qualified< The test is divided into two parts: written test and listening test<
examination content:
the first part is "vocabulary", which is divided into four parts. The first part is 6 "Chinese pronunciation", the second part is 7 "meaning", the third part is 6 "synonyms", and the fourth part is 6 "usage". The overall feeling is that the number of questions is greatly reced and the difficulty is increased
the second part is "grammar", which is divided into three parts. The first part is 10 "grammar choices", the second part is 5 "sentence formation", and the third part is 5 "grammar in the article"
grammar questions are quite different from the previous examination forms. What remains is the first small part of "grammar choice". Although the difficulty of this part is much lower than before, but more emphasis on practicality and solid foundation
the second part of "sentence formation" may be very difficult and time-consuming for candidates, but if we find a way, it can be solved in a short time. In June, I explained and practiced the methods of this part in the exam intensive class. It is expected that all candidates who have participated in this intensive class should have a clear idea
the third part is "grammar in the article". The so-called knowledge workers are mainly engaged in "reading" and "writing". This is also the reason why the proportion of "reading" is greatly increased in the new examination reform. The next "reading" is divided into six parts. The first part is four "short stories", the second part is three "middle stories", the third part is one "long story", the fourth part is one "comparison of two articles", the fifth part is one "long story", and the sixth part is one "information retrieval"
so far, there are 71 written questions, 110 minutes< The fourth part is listening comprehension.

8. For your problem, its coverage is too large and profound! At present, the existence of QQ coin and all network virtual exchange items is to make the company
profitable, and its cost can not be superficial. Who knows or stipulates how much a hat and a dress in QQ embroidery are worth? How much do I sell
it is not the same as a real commodity
you need to estimate its value and how much benefit it can bring to employees. No matter how to determine its cost, it is also virtual. In principle, as long as I meet my
profit goal, this is its cost! It's hard for such a huge system to analyze experts, not to mention you and me? I have a brief understanding as follows

first of all, in Tencent, q-coin virtual transaction phenomenon, a variety of payment means of goods have been derived from a single commodity consumption payment in disguise.
when it is used as the equivalent exchange virtual circulation in the way of RMB, he already has the concept of currency, as a value measure, which is
the intrinsic value measure of goods, In Tencent's website, q-coin can be used to buy virtual goods, such as a virtual QQ show clothes is better than a few q-coins, a virtual avatar is also better than a few q-coins, senior members can use q-coin to pay es, a senior QQ group needs 30 q-coins every month. Q-coin and other virtual currencies can not only purchase various network services provided by their own home, but also purchase network services provided by other enterprises on the Internet, such as Jiangmin antivirus software and other popular software on the network

with such a premise that interests cover a wide range and profits are rampant, all kinds of activities of q-coin trading become more and more interesting

on taobao.com, the seller's quotation for RMB to q is 0.5 yuan to 1q yuan, and the buyer's quotation is generally 0.45 to 0.47 yuan to 1q yuan in private. In addition, the method of purchasing q-coin has been simple

from dealers. It has developed to be able to apply for q-coin with face value of 1

, 2, 5, 10 yuan each time by dialing voice phone or mobile phone, which is equivalent to 1, 2, 5, 10 yuan dected from the telephone fee# Then how to get the source of goods at a low price, there are some new problems, such as the current market price of the serial number is 10000 numbers. If it is first-hand, the price is about 220 yuan. Then we can check the number through the serial number tools: jqq, PQQ, etc. the machine is fast and the network is good. We can check more than 10000 numbers in an hour, Can automatically find out each number

how many Q coins, game currency, level, whether there is password protection, points and so on can be at a glance

generally only sell 1-9. Some people sell 1-4, 5-9 separately. The price is about 1-4.14 yuan and 5-9.23 yuan respectively. It can be said that Q coin has the most negative nature of

but it is not difficult to find that in the case of incomplete relevant laws in China, the hidden dangers can not be ignored

the above is limited to space, and I only talk about some rough and obvious things. I hope you can study them together!
