1. Digital currency

digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and password currency belong to digital currency

digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography

features: the use of P2P peer-to-peer network technology to issue, manage and circulate currency theoretically avoids bureaucratic examination and approval, so that everyone has the right to issue currency

Electronic money means that a certain amount of cash or deposit is exchanged from the issuer and the data representing the same amount is obtained. By using some electronic methods, the data is directly transferred to the payment object, so that the debt can be paid off. Strictly speaking, consumers pay traditional money to the issuers of electronic money, and the issuers store the equal value of traditional money in the electronic devices held by consumers in electronic form. In short, when we deposit money into our bank account, there will be an extra number in the bank account, which means how much money we have saved. In this process, we give the banknotes in our hands to the bank, and the bank adds a number to our bank card, which is our electronic currency

features:

e-money and paper money (or physical money) can be easily converted to each other

the data of electronic currency corresponds to the same amount of physical currency

we need to pay physical money to the issuers of e-money (banks and other financial institutions) in order to exchange for the same amount of e-money

3. The similarity between digital currency and electronic currency: both exist in the form of electronic data

The differences between digital currency and electronic currency are as follows:

electronic currency has an issuing institution, and the corresponding amount of physical currency in the institution can be exchanged with physical currency; However, digital currency has no specific issuing institution (decentralization) and can only exist in network data

at present, there is no international consensus on whether digital currency is a currency or not, so in China, the main form of digital currency is "investment proct", which is a rather risky investment proct, and only a few businesses are willing to accept digital currency consumption; Of course, some countries (Germany, etc.) have officially recognized the currency status of digital currency

3. Digital currency is the need of future development. From animal tooth and shell currency to metal currency and paper currency, human beings have all developed for the development of Commerce and trade. It is not the proct of political groups. It is the proct of social and economic development. The right to issue currency is snatched from the people by political groups, which is forcibly snatched for the benefit of some economic and political groups Not all currencies are issued by the government: for example, the Hong Kong dollar, the euro and other digital currencies issued for banks and political groups are the proct of shearing and manipulation by interest groups like the United States. It is also the necessity of printing and issuing trade currency if you want to. It is the proct of social economic science and technology, so it is the necessity of development. I think digital currency is the medium of trade exchange in the future. Share source video.

4. 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.

5. blockchain and distributed ledger technology make digital currency development more reliable
blockchain technology has been questioned by the collapse of the centralized currency exchange, but its potential to solve the trust and centralization problems of the existing information architecture has attracted a lot of attention. Blockchain technology first gained great popularity in the field of bitcoin and digital currency. It uses a single shared ledger to store information. It is no longer to let a single central organization obtain the account book, but to obtain multiple copies of the same distributed account book by different nodes in the peer-to-peer network. Shenzhen yuanzhongrui blockchain technology adopts advanced encryption technology to ensure that any new information in the account book can not be tampered, unless it meets some preset parameters. Moreover, this kind of Ledger has stronger defense against external attacks, such as network attacks, because this decentralized system does not have a single point of failure with high cost of centralized information architecture. At the same time, all trusted nodes can affect any modification of the ledger, provided that they meet the specific preset parameters. These changes will be immediately reflected in the ledger, and all trusted nodes can obtain relevant data to make correct decisions. It can also adjust the design of the distributed ledger, create a hierarchical system within the architecture, and configure appropriate access rights and different levels of authority
blockchain and distributed ledger technology are concive to change the management mode of land registration. At present, the credibility of the real estate market is at the lowest level, which is attributed to the inefficient and opaque property registration system. The system relies on the centralized acquisition of land registration and corresponding property transaction information. Using distributed ledger technology to obtain, manage and modify these information can ensure that the public will not be infringed by land transaction fraud. Similarly, distributed ledger can simplify and integrate cross instry and cross regulatory compliance process, because it contains real-time compliance information needed by government departments, banks, investors and other third parties. By integrating data points of multiple projects and providing feedback on beneficiaries' project participation, we can better track the implementation of social welfare plans
at present, the biggest problems of technology development include: transformation cost of unique data storage system, data reliability verification of network nodes or all levels, privacy and security dimension of decentralized data acquisition, and revision of information technology act. What's important is that blockchain technology will change the way the government interacts with citizens, and this huge change is bound to be resisted by civil servants. These are all possible problems. We should take immediate action to formulate a regulatory framework to guide application development in addition to adopting blockchain technology.

6. Hello, with the continuous development of modern science and technology, digital information technology is more and more developed, and the developed countries in the world are slowly promoting the process of digital currency
therefore, as the world's second largest economy, we need to develop and implement digital currency
the above are my personal suggestions, which I hope will be helpful to your questions.

7. When it comes to "modeling", we can only rely on "appearance design"

according to the definition of "appearance design", it refers to the new design of proct shape, pattern or their combination, as well as the combination of color, shape and pattern, which is aesthetic and suitable for instrial application

it can be seen that the carrier of modeling must be "proct". If your "coin" is a souvenir or decoration, it should be a proct and can be declared. But if your "coin" belongs to money, it can't.
