National speech on blockchain

1. The subversive characteristics of blockchain lie in the following four aspects: first, transparency. The data record of the blockchain system is transparent to the nodes of the whole network, and the update operation of the data record is also transparent to the nodes of the whole network, which is the basis of the trustworthiness of the blockchain system. Because the blockchain system uses open source programs, open rules and high participation, the data records and operation rules of the blockchain can be reviewed and traced by the nodes of the whole network, with high transparency< Second, openness. The blockchain system is open. In addition to the fact that the private information of the parties directly related to the data is always encrypted, the data of the blockchain is open to all (except the blockchain system with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the open interface, so the information of the whole system is highly transparent< Third, information can not be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for private blockchain systems with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high
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. 1) First of all, it defines the technical value and positioning of the blockchain. As I said at the beginning, the positioning of the blockchain should take the blockchain as an important breakthrough for core technology and independent innovation
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.

3. China's local policies have been introced, which series of related policies? This is not very clear. Is this a national document?

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 ability

a 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 sea

another 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

5. As long as it is beneficial to the people, it can be supported. However, blockchain is hard to say. I always think it is equivalent to MLM

6. The emergence of blockchain is an iteration of economic and social evolution to a certain extent. It can improve economic growth and break the original investment threshold. The characteristics of blockchain make investors happy. However, e to the progress of national strategy, blockchain has developed rapidly and has been valued by the state. It's good to have a hashton blockchain company.

7. There is no clear content for proposing blockchain technology. Blockchain technology is a key to proction and marketing with instrial park as the leading role. There are planting instry and breeding instry in rural areas. This is a very complex problem, and it is difficult to make it clear in one or two sentences.

8. Blockchain experts from 15 countries discussed future network protocols for blockchain and cryptocurrency

the change of Russia's attitude has a lot to do with the economic downturn in recent years and the Western sanctions

Russia's unreasonable economic structure and excessive dependence on oil resources have become the consensus of all walks of life at home and abroad. At the end of 2013, the conflict between Russia and Ukraine, the outbreak of the crisis in Ukraine, western countries imposed economic sanctions on Russia, the global crude oil price plummeted

in November 2014, Russia's GDP began to grow negatively, falling by 3.7% and 0.2% respectively in 2015 and 2016
