The influence of digital currency on the development of digital
we can understand that digital currency is an account book containing all historical transactions. Each block will have several transaction records, which can be viewed by all participants. Each participant of digital currency has to maintain this account book together, Digital currency is a collection of transaction data
for example, in the field of digital currency bitcoin, there will be the concept of "miner". Miner needs to constantly repeat operations to generate workload, and each miner has competition. It needs to complete a mathematical problem based on cryptographic hash algorithm. The answer is in the area, if who works out the answer first, So who can broadcast in the network that he has obtained this block, other miners will not go to this block for mining, but will work in the next block. Miners will have more transaction costs in his block, and they will generate what we call digital currency bitcoin as a reward, and then they will go to their own digital currency bitcoin account
there is no problem with digital currency itself. There may be criminals using digital currency as a cover to cheat, which needs to be carefully screened
1. The volume of digital currency is too large. With the development of digital currency, the volume of digital currency stored in nodes is becoming larger and larger, and the computing burden is also increasing. Colleagues have also caused a lot of impact on the operation of digital currency bitcoin client
2. There is a problem with the data confirmation time. The time for a digital currency bitcoin transaction is about 10 minutes. If we confirm six times, we need to wait for an hour, which is a long time;
when people are used to digital currency, paper money will graally withdraw from the circulation market and enter the collection field. In the new environment of payment and circulation, the traditional paper money will become a symbol of an era and a memory of people. The paper money that used to circulate in the market will also become a kind of cultural and artistic investment goods, active on the electronic disk of the post money card. And those earlier and even rarer coins will also stimulate their prices to rise in this situation. It can be seen that the central bank's graal promotion of digital currency will have a profound impact on people's living habits and investment and financial management, which is worth looking forward to Sohu)
however, digital currency does not have to be used for payment. Some domestic application-oriented digital currencies have begun to find another shortcut and come out with a different truth. For example, coin Ying China crowdfunding project token; Puyin group launched the tea based digital currency Puyin.
The digital RMB red envelope of 10 million yuan issued by Shenzhen city has brought the development of e-money back to the people's vision
in fact, since April 2020, small-scale pilot projects of digital RMB have been carried out in Shenzhen, Cheng, Suzhou and xiong'an, and the pilot scale will be expanded to 28 provinces and cities in August 2020
as a socially recognized "super outlet", in addition to the high investment of digital currency related enterprises, its impact on the financial market is also of great research value
Policy evolution of the development of digital RMBas early as 2014, the central bank has concted research layout on digital RMB, and discussed the development framework of digital RMB with major international financial institutions and research institutions in the 2016 digital currency seminar
after six years of development, China has initially developed the "pbctfp blockchain platform" and continuously promoted the pilot activities of digital RMB. It can be predicted that as today's technology and policy outlet, digital RMB will have excellent development prospects and extremely fast development speed in the next few years
Figure 1: Policy Evolution of digital RMB
with the improvement of China's national strength, digital RMB provides an opportunity to establish a "new system of RMB cross border settlement", which can promote RMB payment activities around the world and realize the internationalization of RMB
bitcoin is valuable because it is useful as a form of currency. Bitcoin has the mathematical characteristics of money (persistence, portability, interchangeability, scarcity, separability and identifiability) rather than relying on physical characteristics (such as gold and silver) or the trust of central authorities (such as fiat money). In short, bitcoin is backed by mathematics. With these characteristics, a form of money to have value requires trust and use. In contrast, this can be reflected in its growing base of users, businesses and start-ups. Like all currencies, the value of bitcoin comes directly from people who are willing to accept it as a means of payment, which is the only source.
90% of stocks are money frauds. Don't look at how good PE looks. Next year, we will directly rece goodwill, not too elegant, and drop 90% in a straight line! I'm not talking about Tianshen entertainment. Please don't take your seat according to the number. I'm talking about all the small cap stocks
if you are not a technology stream, don't read the code or the white paper, then you can play with virtual currency
no matter what genre you are, don't touch stocks. You'd rather live than die
the basic threshold of Minstry is a little high. Let me talk about the new strategy today< 1. Defense facilities: basic technology, necessary items for defense
according to size, it can be divided into small (1x1), medium (2x2), large (3x3) and super large (4x4)< The attack targets can be roughly classified as ground, air, land and air joint
2. Mineral drill: the only way to obtain materials except hand drill can be divided into electric drill and non electric drill. The mining intensity of each miner is different. Let's talk about the mineral hardness. Different minerals have different hardness, and the corresponding mining speed is different. For example, if the mining intensity of dart is one, it can only dig minerals (copper, lead) with hardness less than or equal to one, but not minerals (coal, titanium, thorium) with hardness higher than one
3. The transportation system (solid) does not have one of the necessary materials for each bureau
it can be roughly divided into conveyor belt, conveyor bridge, material cannon and connecting equipment
conveyor belt: directional three-way access, basic transport materials (attachment: transport speed is directly related to distance, and can be accelerated)
conveyor bridge: directional multi terminal access, basic transport materials (attachment: transport speed is not related to distance, and can be accelerated), No acceleration)
material Cannon: directional single end entry, advanced transport material (attachment: transport speed has an indirect relationship with distance, which can be accelerated)
connecting device: non directional four side entry, basic transport material (attachment: transport speed has a direct relationship with arrangement, which can not be accelerated (warning: simultaneous router is extremely not recommended))
4, The details are the same as above, but the simultaneous router will not affect too many speed 5, power, extremely important resources in the later period The key points of drawing are connection points. The hubs that can be connected with multiple objects have upper limit of connection (Note: the connection points are connected with each other to occupy the connection space), battery, temporary power storage unit, rectifier effect diode with reference to actual capacitance, anti negative power (I'll do the tutorial next time, this is the new strategy) power station, power generation unit. There is the nature of blood loss (Note: power generation materials are explosive, the higher the probability and rate of blood loss), and the priority of new technology is pump and turbine. 6. Walls are defense units that block bullets. Some penetrating ammunition can't block them. They can be roughly divided into three categories. Ordinary, special effect, door ordinary, is the literal meaning of anti injury, there is no other special effects. For special effects, the plastic steel wall (absorbing arc, including its own side (Note: it can be used as a small battery without reserve (maybe the next tutorial), the special effects of small plastic steel and large plastic steel are the same), the fabric wall (rebounding most bullets), and the alloy wall (being hit will be blebbing discharge) are extremely not recommended to be used with the plastic steel wall. Door, own door, click to switch (disappear) 7, factory, used to upgrade the raw materials of advanced items The only thing to be reminded is that routers should not be put together with factories. Because the router is not directional. The material from the factory will flow back into the router. You'll get stuck in your purchase belt 8, arms factory, input materials and electricity to build troops. There's nothing to introce. The command post is an offensive unit. There are three commands (attack (start to the enemy's core, no, just go to the nearest monster's birthplace), assemble (circle around the command post), and retreat (circle around the factory)) to repair the unit. The injured unit will automatically go to the repair device and turn around. 9. Transform the platform to change your armor. The basic data of each set is different. See for yourself in detail 10. Other items, a mess of things, repair instrument (knock on the blackboard), give the surrounding friendly building units the percentage health value every second Accelerator (tapping on the blackboard). The point is that the official introction letter is wrong. It can accelerate almost all items (I have marked those that can't be accelerated) and can be superimposed with other acceleration effects (such as the water of the mining machine or the coolant of the battery). The shield is superimposed by multiplication. The absorbing bullet (note that the absorbing bullet) has shield capacity and threshold, (shield capacity: as the name suggests, it is the upper limit of the damage a shield can take) (the threshold is the amount of recovery per second of the shield capacity (which can be accelerated by liquid)) (cooling is the recovery speed of the shield after being blasted (which can be accelerated by liquid)). It can't be accelerated by accelerators to store goods and materials. There's nothing to introce about this use. Expand the core capacity, Next to the core manufacturing complex (I think the biggest use is to increase the core interface) launch pad, launch materials (to your space station, you can unlock the technology tree, or bring it down (start)). This launch material (next to the core manufacturing complex) is not easy to introce. When it is powered on, it can be launched as a percentage of all materials (only basic technology can, other mod's are quantitative launch)
A few days ago, a representative said that the development of digital currency has the inevitability of technological development, and the research on it is accelerating in all countries. At the same time, the possible risks of digital currency will become one of the focuses of financial supervision in the future, so that it can better serve the economic development
digital currency is the cornerstone of digital economy. In the future, the introction of digital currency will greatly accelerate the development of digital economy, promote the improvement of social efficiency and cost rection. However, in the process of designing, issuing and circulating central bank digital currency, we should fully consider the diversity and complexity of system and system design
analysts said that the cost of issuing, printing, recycling and storage of existing banknotes and coins is high, the circulation system is multi-level, and it is inconvenient to carry, easy to be forged, anonymous and uncontrollable. There is a risk of being used for money laundering and other illegal and criminal activities, and the necessity of digitalization is growing
The rise of financial technology promotes the digital and intelligent development of finance, and the form of money is also developing. With the rapid development of information network communication technology, electronic payment has been popularized rapidly, and legal digital currency is also developing< China vigorously promotes digital currency, and the development of digital currency has great positive significance for China's economic development
finally, it is difficult for users to feel the difference between digital RMB payment and third-party payment in their daily consumption. In comparison, the use of digital RMB payment is more convenient than the third-party payment , and digital RMB payment is not limited by the network and payment scenarios. Digital RMB is the financial infrastructure built by the state, and there is no charge for the cashing and redemption of digital RMB. Digital RMB can be used to pay third-party payments. However, for those who need convenient electronic payment, people without financial accounts can also use digital RMB< Digital RMB supports controllable anonymity, which can better protect users' privacy
