Blockchain is an idea

1. 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.

2. Many relationships between people are based on trust, such as friend relationship, cooperation relationship, transaction relationship, etc
take trading activities as an example. In the past, the two sides who did not trust each other usually chose an intermediary to guarantee a transaction. In the mobile Internet era, we chose Taobao shopping because Alipay provided us with an intermediate guarantee. We chose to drop dripping because it provided us with information matching.
however, these intermediaries are centralized and have their own interests. Sometimes they are not so reliable and trustworthy. Theoretically, Alipay's centralization of accounting has been artificially falsified. Part of the reason for Didi's troubles is that they only think from their own standpoint
what blockchain does is the machine of trust, which replaces the role of trust intermediary with code, ensures the fairness and justice of the whole system through consensus mechanism and distributed accounting, and provides a trust without trust
for example, in the future, people can abandon the intermediate platform and realize point-to-point docking and free trading through blockchain. Shopping does not need to go through an intermediary, and taking a taxi does not need to go through Didi. In this way, we can really achieve "no middleman to earn the price difference" and rece the cost.

3. 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

5. 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.
