Does China vigorously develop blockchain
if you look at the problem with the thinking of 30 years ago, you will think that others are crazy, but in fact you are out of date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.
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.
2) blockchain, Internet and artificial intelligence should be regarded as technologies of the same height, and blockchain should formally enter our hard science and technology development category
3) pointed out the development and application direction of our blockchain, including the speech that the technology of blockchain has extended to many fields, such as digital finance, Internet of things, intelligent manufacturing, supply chain management, digital asset trading, and so on. In terms of application, there will inevitably be some regulatory or legal problems in the process of application, What are the instructions in this speech? He mentioned that we should implement the rule of law in the management of blockchain, and promote the safe and orderly development of blockchain
4) in the more important point of application and development, it is mentioned that the blockchain is from virtual to real, enabling entity, improving people's livelihood, obtaining instrial advantages, and better serving the development of the whole instrial economy. In fact, through the study of blockchain technology, from one side or the signal released, we express our attitude towards the innovation and leadership of blockchain. We hope that in the development of blockchain, we can first have our own core technology, and we should be a leader in today's fierce international competition
5) it is to enhance the market confidence of the whole blockchain instry, especially for the application and development of the whole blockchain technology. With a great increase in market confidence, it is bound to attract more people in the next period of time, including the capital market and for example, more talents and research applications will enter this field. More capital, more manpower and more other social related aspects, including the rule of law and legislation, will positively promote the application and landing of the whole blockchain technology. These are my four points of view or summary of blockchain technology learning
if you have been concerned about blockchain for a long time, in fact, from the national level, including the 13th five year plan, blockchain technology has been written into the 13th five year plan, which is developed as a parallel technology with artificial intelligence, big data and cloud computing. It has been introced in the second half of 2018, and the office of network information technology has put the blockchain application service on record, From all aspects, it is actually a positive guidance or protection for the development of the whole blockchain
of course, when it comes to blockchain, you may also say that blockchain always thinks of money speculation and so on. In fact, digital currency is only a relatively narrow field in the field of blockchain. We now include support from the mainstream of modern society or the national level, and more support for the application of blockchain technology in the real instry, The core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in the distributed system without mutual trust by means of data encryption, timestamp, distributed consensus and economic incentives, so as to solve the common high cost and low cost problems of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
the blockchain instry is on the eve of the application outbreak
as a kind of underlying technology, with the support of policy direction, blockchain is attracting more and more exploration of application landing. At the recent 2019 future business ecological link conference, Zhu Youping, deputy secretary of the general Party branch of China economic network management center of the state information center, pointed out that after 11 years of trial and error, the technology of blockchain has basically been commercially available, and the instry is now on the eve of application explosion
Wu Xiaochuan, a senior expert in Zhongan technology's blockchain development, told the 21st century business reporter that the biggest difficulty in the current blockchain landing instry is how to map the physical world and the blockchain world one by one, which needs multi-disciplinary joint efforts to solve. Internet of things technology is an important part of it. With the blessing of 5g, cloud computing and other technologies, it will bring more complement and support to the implementation and application of blockchain technology in the futureaccording to the prediction of tractica, the analysis organization, the global enterprise blockchain market will reach US $20.3 billion by 2025
key node of technology and standard promotion
compared with other underlying technologies, blockchain has also experienced a relatively tortuous development process, and there is still a way to go in terms of integration with multiple technologies and setting of its own standards
Zhang Xiaojun, head of Huawei's blockchain, pointed out in his speech at the conference that today's blockchain technology is more like the development stage of the Internet from 2002 to 2003. If the relevant standards of blockchain can be mature in 2020, including cross chain standards, storage standards and standard data format storage, large-scale commercial use will be accelerated in 2021
China's blockchain instry is still in its infancy, but with the continuous support of national policies, the continuous progress of instry technology and the increasing demand of downstream applications, China's blockchain instry is expected to continue to maintain high-speed growth. In 2011, the market scale of China's blockchain instry was less than 6 million yuan. By 2018, the market scale of China's blockchain instry has grown to 67 million yuan, maintaining a rapid growth rate of more than 80%. It is estimated that in 2022, driven by policy support and downstream demand, the market scale of China's blockchain instry is expected to exceed 450 million yuan
market size statistics and growth forecast of China's blockchain instry from 2015 to 2022 Zhu Youping pointed out to the reporter of the 21st century economic report that with the technical blessing of 5g and even future quantum computing, these weaknesses will be quickly made up
for more data sources and analysis, please refer to the in depth analysis report on business model innovation and investment opportunities of China's blockchain instry published by foresight Instry Research Institute. Meanwhile, foresight Instry Research Institute also provides instrial big data, instrial planning, instrial declaration, instrial park planning, instrial investment promotion and other solutions
blockchain projects are also projects. If you want to add value to your investment, you need to have the following aspects:
1, self-development ability, complete business system and investment guarantee mechanism. This is very important. Many projects do not mention the investment guarantee mechanism, which is to leave a way out for the future
PS: it's said that the project of global integral treasure is quite good. You can pay attention to it.
Since the 1970s, a new energy, combustible ice, has been discovered in the deep sea around the world. If you listen to this term, you will be surprised! How can ice burn? In fact, combustible ice is a kind of crystal material formed by the combination of water and natural gas, which is called "natural gas water compound" academically. According to measurement, 1 cubic meter of solid combustible ice contains about 200 cubic meters of natural gas. Therefore, combustible ice has a strong combustion capacity and is a very important energy resource
The discovery of combustible ice was e to a chance. In the 1930s, in order to transport natural gas, people began to lay huge natural gas pipelines. The results show that the pipeline is often blocked. Cut the pipe open and see that it was blocked by ice like material. How can there be ice in the pipe? After research, it turns out that it is a combination of natural gas and water, with strong combustion abilitya large amount of combustible ice is stored in the frozen soil and seafloor, and the most abundant is in the deep sea. On the sea floor, combustible ice often forms huge deposits with a length of several thousand meters and a thickness ranging from several centimeters to 200-300 meters. In the United States, Canada and other coastal areas, it has been found that there are tens of billions of cubic meters of combustible ice resources, which can be exploited for hundreds of years. Russia, New Zealand, India, Japan and other countries have also found considerable reserves of seabed combustible ice resources. Combustible ice is also found in the East China Sea, South China Sea and Yellow Sea. It is estimated that the reserves of combustible ice in the world are very huge, at least more than twice of the total reserves of coal and oil. It has been hailed as the new energy of the future
There are some difficulties in mining combustible ice because it is deep in the ocean and frozen soil. So far, there is no successful experience in mining seabed combustible ice in the world. At present, there are two mining plans in people's imagination, one is to connect the pneumatic pump pipe with the receiving ship. The air pressure pump pipe extends directly into the sea floor, and the lower end of the pump pipe is a huge bell shaped object, which can cover an area under the water. There is also an automatic mining machine inside the bell, which will dig up the rocks with combustible ice on the seabed together with the combustible ice, smash them into pulp, and then transport the pulp to the receiving ship through the pneumatic pump pipe. On the receiving ship, the natural gas in the combustible ice is separated by heating and pressurizing, while the remaining marine sediments often contain other available substances, which are separated and extracted for the second and third time. Finally, the useless resial soil is poured into the seaanother solution is to directly decompose combustible ice into ice and natural gas on the sea floor, and then transport it directly to the ground gas storage tank, just like the natural gas in the rock stratum, and then transport it to the users who need natural gas from the gas storage tank. Compared with the former scheme, the transportation condition of the latter scheme is relatively simple, which is expected to save more mining cost. But the problem is that the decomposition technology of combustible ice on the seabed is still immature; In addition, this scheme can not make full use of other resources that may exist in the seabed of the mining area
