The milestone of digital currency in China

1. Let's first explain digital currency. The real digital currency is issued by the state, based on the national credit, and stored in the form of electronic data. This is the national legal currency that can be circulated. So far, no country has issued digital currency, so has China. Therefore, anyone claiming to be a digital currency issued by the state is a fraud. The function of legal digital currency is the same as that of paper currency. So there is no concept of investment. Just imagine, would you spend 100 yuan to buy a ten yuan RMB? bitcoin is still a virtual currency, not a real currency. Bitcoin is an encryption algorithm based on the blockchain, and the calculation results are obtained. The biggest characteristics are decentralization, uniqueness and finiteness. Because of these characteristics, it is impossible for a country to use bitcoin as legal tender. So I have no objection to using bitcoin as a target of speculation. But if bitcoin is promoted as a digital "currency", I think it is suspected of cheating, because it does not have the characteristics of national legal tender. Some people in the world are willing to accept bitcoin transaction. I think it is actually a "barter" transaction, not a real currency transaction. At present, bitnet exchange can provide the most trading pairs, and investors can participate in leveraged trading and perpetual contract trading.

2. Knowledge based military, intelligent weapons, digital battlefield, information war and deterrence strategy have become the basic trend of military development in the 21st century, and the discipline comprehensiveness is more prominent. In the future, any solution to military war problems, science and technology problems, social development problems and environmental problems will be highly comprehensive, and almost all disciplines and specialties can become the research objects of national defense science and technology. In 1993, the U.S. Department of defense launched an action to jointly formulate a defense science and technology plan, and proposed to the Joint Chiefs of staff the 2010 joint operations vision, the joint operations science and technology plan, the defense technology field plan, and the basic research plan, covering almost all military related science and engineering fields. The basic research program alone covers 12 disciplines, including physics, chemistry, mathematics, computer science, electronics, materials science, mechanics, marine science, earth science, atmospheric space science, biological science and cognitive neuroscience. We should change our traditional thinking, build an advanced and reasonable discipline system of national defense science and technology, create a world-class university with our military characteristics, and enrich and develop national defense science and technology in accordance with the development mode of "military, comprehensive, research and open". The characteristics of military confrontation are distinct“ The rule of "there is a spear, there is a shield". Science and technology itself is a double-edged sword, while national defense science and technology have more distinctive military antagonism: reconnaissance and anti reconnaissance, stealth and anti stealth, jamming and anti-jamming, guidance and anti guidance, destruction and anti destruction, virus and anti-virus; Tank anti tank, missile anti missile, aircraft carrier anti aircraft carrier, satellite anti satellite; Air attack and anti air attack, landing and anti landing, blockade and anti blockade; Information attack and defense, electronic countermeasure, missile attack and defense, system of systems countermeasure; Weapon informatization and information weaponization, new concept weapon and new concept weapon all embody two aspects of one problem. New concepts of weapons emerge one after another. New concept weapon is a historical category, and its breakthrough is of milestone and epoch-making significance. In the era of cold weapons, it is difficult to divide attack and defense when short soldiers fight; In the era of hot weapons, the combination of attack and defense, long-range mobility; In the era of nuclear weapons, it is extremely powerful and can deter qu bing. In the future battlefield, there will be too many new concept weapons: kinetic energy weapons such as electromagnetic energy launchers and electrothermal guns, which use electric pulse power as energy to break through the speed limit of conventional artillery systems; Laser weapons, high-power microwave weapons, particle beam weapons and other directional energy weapons have changed the traditional thinking of "gun, gun and bullet", and realized the dream of "gun without bullet, zero hour flight, direct aiming"; Gene weapons can destroy a certain race or a certain kind of people; The infrasonic weapons hide the killing machine in the silent place, which makes it more difficult for people to defend; There are also micron / nano weapons, digital intelligent robot forces... The new concept of weapons is the broad sense of weapons, which regards all means beyond the traditional military field, but still can be used in war operations as weapons. In the era of information network, man-made stock disaster, hacker intrusion, false intelligence and power failure can be included in the new concept of weapons. The new concept of weapon provides direction for the new concept of weapon, and the new concept of weapon makes the new concept of weapon fixed. New concept weapon is the concentrated embodiment of military knowledge innovation and military technology innovation. In the era of knowledge military with the rapid development of national defense science and technology, new concepts of weapons beyond the modern era emerge in endlessly, and new concepts of weapons beyond the future will continue to emerge. The al-use of military and civilian is increasingly obvious. Modern high technology is almost all al-purpose technology, with the characteristics of strong versatility. The progress of science and technology in the field of information and the Kosovo war show that the boundary between the army and the people is becoming more and more blurred. The basic science and technology involved in national defense science and technology include infrared technology, low light level technology, laser technology, radar technology, optical fiber technology, photoelectric inertial technology, integrated optical technology, computer technology, communication technology, artificial intelligence technology, virtual reality technology, and management technology. Most of them are highly versatile technologies, It can support the development and transformation of many kinds of weapon systems, and has distinct al-use characteristics. Dual use, mutual promotion, is a direction. On the one hand, in the design phase of the new system, civil technology, procts, practical experience and capabilities should be used as much as possible, and the economic bearing capacity should be fully considered; On the other hand, many key technologies of national defense are being developed or matured in the commercial and international fields. Therefore, the proction of military procts and civilian procts will rely on the same instrial base as much as possible to give full play to the advantages of economies of scale and technological innovation of civilian instry. At the same time, the military system and national defense departments will also maintain stable scientific research funds, maintain investment in key defense science and technology fields, carry out high-quality basic research, cultivate future scientific and technological teams and "smart buyers", promote cooperation between scientific research institutions inside and outside the military, accelerate technology transfer, and selectively use technology to meet social needs.

Digital currency has been issued in some cities in China, but it will take some years for it to be popularized{ RRRRR}

3. It takes a while for digital currency to be popularized in an all-round way

digital currency is to turn paper money into a number that people can see on the Internet, which is more convenient for people to operate as long as we use the mobile phone in our daily life, we can complete a series of commodity transactions without using the Internet. At that time, it will be the real realization of a mobile phone that can travel all over the world
