Digital currency issuing system
1. The concept range is different. bitcoin is a kind of digital currency, and the concept of digital currency covers bitcoin
However, some digital currencies have independent issuers The biggest difference between bitcoin and other virtual currencies is that the total quantity of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 milliondigital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Bitcoin is a 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 currencies, such as bitcoin, lettercoin and ppcoin, are electronic currencies created, issued and circulated by means of check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency
illegal digital currency
in recent years, "virtual currency" represented by bitcoin, Ethernet currency and Leyte currency has been traded centrally on some Internet platforms. With the help of financial technology, the price of these "currencies" has graally spread to investment, financing and other financial fields, which has aroused wide attention from all walks of life
not long ago, the people's Bank of China and other seven ministries and commissions jointly issued the announcement on preventing the financing risk of token issuance, which clearly regulated the relevant behaviors. Experts pointed out that "virtual currency" is not legal tender (legal currency) issued by monetary authorities, but a specific virtual commodity in essence
therefore, it is undoubtedly a great legal and economic risk to think that "virtual currency" has or will have the nature of legal tender and to carry out speculation, network fund-raising, lending and financing
according to media reports, the people's Bank of China has completed a test on December 15, which shows how to conct transactions and clearing in the distributed ledger system
it is reported that this test was concted jointly with China's mainstream commercial banks, including ICBC, Bank of China and Weizhong bank< The report reads: "the people's Bank of China believes that digital currency can not only rece circulation costs, but also increase transparency, inhibit money laundering and tax evasion."
the report even suggests that Shanghai bill exchange pilot digital currency and set up a national bank bill transaction. At the same time, the people's Bank of China will also establish a digital currency Research Center, and is recruiting experts in big data, cryptography and blockchain technology< The report comes after Zhou Xiaochuan, the governor of the people's Bank of China, issued a statement in February in which he hinted that the people's Bank of China was considering using blockchain to issue digital currency
moreover, this test was concted at the time when the people's Bank of China launched an investigation into China's bitcoin exchange, which started early this month and has led to many changes in trading policies
as the world's first standard digital currency, Puyin takes 1 billion Tibetan tea as the primary standard asset, writes 1 billion Tibetan tea assets into the blockchain through digital encryption technology, and records the identification, evaluation and right confirmation of Tibetan tea.
the birth and popularity of bitcoin all over the world depends on the concept, which is in the foreword of the times. However, bitcoin has been preconceived and cannot be replaced by other digital currencies. Although some counterfeit currencies were popular for a while later, they slowly went down in the end, only bitcoin strengthened. Puyin is another shortcut, as a standard system of digital currency appears, behind the endorsement of related tea assets, its value is recognized by the society.
It is not currently available
at present, the Central Bank of China has not issued and approved the digital currency of issuers and investors
However, at the beginning of the year, the central bank held a seminar on digital currency, at which it made it clear that it was necessary to issue digital currency as soon as possible, and the central bank put the issue of digital currency on the agendahowever, so far, the central bank has not issued any digital currency, and Zhou Xiaochuan, the governor of the central bank, said that the time is not ripe to issue digital currency. Moreover, the digital currency issued by the central bank is different from bitcoin, Ruitai, Laite and other digital cryptocurrencies, and the digital currency issued by the central bank is not decentralized
when the central bank issues digital currency, it needs to establish a basic digital currency system. In this system, the central bank is in charge of the digital currency issuing bank, the commercial bank is in charge of the bank, and the public and indivials hold digital wallets. This is not much different from the existing monetary system in essence, but the managed currency is changed from paper money to digital cryptocurrency
in terms of issuing mechanism, there are two modes:
one is the traditional mode of "central bank commercial bank", that is, the central bank issues digital currency from the issuing bank of the central bank to the Bank of the commercial bank. When an indivial withdraws money from the commercial bank, the digital currency is transferred from the commercial bank to the personal digital wallet
another mode is the "central bank public" mode, that is, the central bank can directly issue digital currency from the currency issuing bank to the digital wallet of the public and indivials. In essence, no matter which issuing mode, money is ultimately held by the public, which is the debt of the central bank to the public
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)
