Think about blockchain

1. Do you want to learn blockchain development technology or just want to know what blockchain is? If it is the former, you can look at the code of other blockchain projects and learn about it first. If it is the latter, we can pay attention to some good blockchain we media. Blockchain is an emerging instry. There is no ready-made training course. It depends on self exploration and understanding.

2. Satoshi Nakamoto, who calls himself Japanese American, is the creator of bitcoin protocol and its related software bitcoin QT, but his real identity is unknown. In 2008, Nakamoto published a paper called "bitcoin: a peer-to-peer electronic cash system", which describes an electronic currency and its algorithm called "bitcoin". In 2009, he released the first bitcoin software and officially launched the bitcoin financial system. In 2010, he graally faded out and handed over the project to other members of the bitcoin community. Nakamoto is believed to hold about one million bitcoins.

3. A brief review of the origin of blockchain
blockchain is the underlying system of distributed ledger in bitcoin. Bitcoin ledgers are built in a distributed and spontaneous way. Anyone can generate new currency blocks by performing specific cryptographic calculations, so as to obtain a digital "currency" that can be used for transactions. Bitcoin's impact on the world monetary system can be said to be subversive, which is also an important reason why it has attracted a lot of people's strong attention since it came out. After that, there were dozens of similar electronic currencies such as
"lightcoin". The abstract extraction of distributed digital currency technology from bitcoin forms a "blockchain" technology, which can be used in more fields
the basic idea of blockchain is to establish a network-based public ledger (data block), each block contains the information of a network transaction. All the participating users in the network work together to keep accounts and check accounts. All the data are open and transparent, and can be used to verify the effectiveness of the information. In this way, the authenticity and non tamperability of information can be guaranteed at the technical level without the central server as the trust intermediary
the significance of blockchain lies in "decentralization", which can fundamentally solve the fraud and rent-seeking phenomenon in value exchange and transfer by building a more reliable network system. With the popularization of blockchain technology, the digital economy will be more authentic, and the economic society will become more fair and transparent
not only digital currency, but also blockchain technology is infiltrating into more innovative fields.
virtual digital currency such as bitcoin is just an application scenario of blockchain technology. Theoretically speaking, based on the characteristics of blockchain technology, human beings can create a very rich form of services and procts, such as finance, government, enterprises, etc There are a large number of scenarios suitable for blockchain technology in cross instry and other fields, with broad prospects. At present, many countries around the world have started the research of blockchain technology, and a series of instry organizations and alliances have been established. However, as blockchain technology is a brand-new technology, which subverts the traditional centralized mode, major institutions are still in the research stage, with only a small number of actual projects landing, and the great development of the instry has just begun
now, blockchain economy is on the eve of outbreak. The exploration of financial instry is ahead of others, while the application of other instries is developing rapidly. The obvious advantage of blockchain instry application is to optimize business process, rece operation cost and improve collaborative efficiency. This advantage has been graally reflected in financial services, Internet of things, public services, social welfare and supply chain management
as the backbone of emerging technologies, blockchain is not only used in the field of virtual currency, but also in other fields such as finance, medical care, intellectual property certification, etc. a large number of excellent enterprises have emerged in China to explore or enter the blockchain instry. According to the in-depth analysis report on business model innovation and investment opportunities of blockchain instry released by foresight Instry Research Institute, as of the end of 2016, there were 105 blockchain related enterprises in China, 80% of which were concentrated in eastern coastal cities, including Shanghai, Hangzhou and Taipei
from the perspective of global blockchain technology application development, as of April 2017, financial service companies accounted for 55.43% of the 267 blockchain venture capital companies; From the perspective of the Chinese market, 34 of the top 50 blockchain venture capital companies in 2016 are involved in financial services, mainly in cross-border payment, bill discounting and financial service platform<
analysis of the development trend of blockchain
the combination of blockchain and cloud computing is more and more close, and baas is expected to become a public trust infrastructure
cloud computing is the general trend. We believe that the combination of blockchain and cloud is also an inevitable trend. There are two modes for the combination of blockchain and cloud, one is blockchain in the cloud, the other is blockchain in the cloud. The latter, namely baas, blockchain-as-a-service, refers to that the cloud service providers directly provide blockchain as a service to users. In the future, more and more cloud service enterprises will integrate blockchain technology into the ecological environment of cloud computing. By providing baas function, they can effectively rece the deployment cost of enterprise application blockchain and rece the initial threshold of innovation and entrepreneurship
the security problem of blockchain has become increasingly prominent, and security protection needs the overall consideration of technology and management
blockchain system is almost perfect mathematically, with the advantages of openness and transparency, difficult to tamper, reliable encryption, anti DDoS attack, etc. However, from the engineering point of view, its security is still restricted by infrastructure, system design, operation management, privacy protection and technology update iteration. In the future, we need to consider the overall situation of technology and management, strengthen basic research and overall protection, so as to ensure the application security
the competition of blockchain is becoming increasingly fierce, and patent competition has become an important field of competition
with the increase of participants, the competition of blockchain will become more and more fierce, and the competition is all-round, including technology, mode, patent and other dimensions. We believe that in the future, enterprises will strengthen the layout of blockchain patents. Since 2014, the number of blockchain patent applications has grown explosively. Blockchain patents are mainly distributed in the United States in North America, the United Kingdom in Europe, China and South Korea in Asia, and this pattern will be maintained in the future. The patent gap between China and the United States is narrowing, and the number of applications in China in 2016 has surpassed that in the United States. It can be predicted that the patent competition of blockchain will become increasingly fierce in the future
with the acceleration of domestic policy process, the development of the instry ushers in a new opportunity
blockchain has attracted attention from all walks of life e to its core advantages of high performance, high security, high-speed access, efficient operation and so on. In the context of the rapid development of blockchain, China conforms to the needs of globalization, closely follows the international pace, and actively promotes the research, standardization and instrialization development of domestic blockchain related fields
trustworthiness is the core requirement of blockchain, and the importance of standards and specifications is becoming increasingly prominent
in the future value delivery network based on blockchain, we will completely use algorithms and software to build the trust foundation. However, we believe that this is far from enough, and we need the standard to increase the credibility of the blockchain. In the future, the standard of blockchain will standardize the technology and governance of blockchain from the perspective of users, business oriented, and from the dimensions of smart contract, consensus mechanism, private key security, and authority management, so as to enhance the credibility of blockchain and add weight to the trust of blockchain.

4. If Cmall goes public as a blockchain, what are the benefits of members of ccmall? Is it possible to realize income?

5. The positioning of cross-border blockchain platform is to serve the real economy, especially banks, enterprises and other service objects. It focuses on "blockchain + cross-border financial services" to promote the exploration of the integration of blockchain and real economy. Now the project of blockchain + service platform is very popular. The project of SMIC blockchain service platform initiated by Changsha high tech Zone is the blockchain + public service mode, and the enterprises are being recruited to join the chain. In the future, relevant enterprise affairs and government affairs can cooperate on the chain, and also have the background of state-owned assets.

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

7. In his opinion, many of the technology centers currently used by blockchain are technologies already in use, so it is not new to look at blockchain from a technical perspective. But the real value of blockchain lies in its point-to-point, tamper proof and traceable design idea, which will change people's way of life and work.
