The influence of digital currency on tax rate
many procts of blockchain technology are not currency, although they are called currency. Under the guise of digital currency investment, it is a Ponzi scheme. Even some of them don't even have blockchain technology, which is just a fake number to cheat people.
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;
For atoms: the number of electrons and protons is the number of elements. For example, h is element 1, which contains one electron and one proton
The neutron number should know the mass number. If you haven't learned this yet, the mass number can be simply regarded as the relative atomic mass, the number of neutrons = the relative atomic mass minus the number of protons. For example, if O is element 8, it has eight electrons and eight protons. Relative to the atomic mass of 16, the number of neutrons = 16-8 = 8for ions, protons and neutrons are exactly the same as above, and electrons change, gain more and lose less. The method is similar
the number of electrons outside the nucleus = atomic number = proton number inside the nucleus = nuclear charge number (the number of electrons outside the nucleus of an ion = atomic number (sum) - charge number)
the maximum number of electrons held by each electron layer is 2n ^ 2 (n is the electron layer number). The number of electrons in the outermost layer is not more than 8 (when the k layer is the outermost layer, it is not more than 2). There are no more than 18 electrons in the second outer layer and 32 electrons in the last three layer
the extranuclear electrons are always arranged in the electron layer with the lowest energy first, and then from the inside to the outside, they are arranged in the L layer and then in the m layer. The above four laws are interrelated and cannot be understood in isolation
extended data:
neutrons exist in neutron stars as clusters (neutron stars are one of the few possible endpoints after supernova explosions e to gravitational collapse at the end of star evolution.) In the middle. The neutrons in the solar system mainly exist in all kinds of nuclei, and the neutrons in the elements are very rare β Decay is a change in which the neutron in the element releases an electron to become an element of the previous element sequence
Neutrons can be classified according to their velocities. High energy (high-speed) neutrons have the ability to ionize and penetrate deep into matter. Neutrons are the only ionizing radiation that can make other substances radioactive. This process is called "neutron excitation"“ "Neutron excitation" is widely used in the proction of radioactive materials in medical, academic and instrial fields High energy neutrons can travel very long distances in air. Neutron radiation needs to be masked by hydrogen rich materials, such as concrete and water. Nuclear reactor is a common neutron source, and water is used as an effective neutron shieldarrangement rule:
1. The electrons are arranged in different layers from the nucleus to the nucleus, and the energy is from low to high
The maximum number of electrons in each layer is 2n2 (n is the number of electron layers) There are no more than 8 electrons in the outermost layer (no more than 2 in the first layer), no more than 18 electrons in the second outer layer and no more than 32 electrons in the last three layers In general, the electrons are always in the lowest energy layer, that is, the first layer, when the first layer is full, then the second layer, when the second layer is full, then the third layerDigital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields besides digital currency , which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market, financial stability and so on. Specific Wu Xiaoxia:
1. Impact on monetary policy
if digital currency is widely accepted and can play the role of currency, it will weaken the effectiveness of monetary policy and bring difficulties to policy-making
because digital currency issuers are usually unregulated third parties, money is created outside the banking system, and the amount of circulation depends entirely on the wishes of the issuers, which will lead to the instability of money supply. In addition, the authorities are unable to monitor the issuance and circulation of digital currency, which will lead to the inability to accurately judge the economic operation and bring trouble to policy-making, At the same time, it will weaken the effectiveness of policy transmission and implementation
2. Impact on financial infrastructure. The use of distributed ledgers also poses challenges to trading, clearing and settlement, as it promotes the disintermediation of traditional service providers in different markets and infrastructures. These changes may have potential impacts on market infrastructure other than retail payment systems, such as large payment systems, securities settlement systems or trading databases
3. The impact on financial intermediation and financial market in a broad sense. As a financial intermediary, banks perform the ties of acting supervisors and supervise borrowers on behalf of depositors
generally, banks also carry out liquidity and maturity conversion business to realize the financing from depositors to borrowers. If digital currency and distributed ledger are widely used, any subsequent disintermediation may have an impact on savings or credit evaluation mechanisms
4. The impact of security risks and financial stability
assuming that digital currency is recognized by the public, its use increases significantly and replaces legal currency to a certain extent, negative events such as network attacks on user terminals related to digital currency will lead to currency fluctuations, which will have an impact on the financial order and the real economy
in addition, the virtual currency based on blockchain technology is usually held by a few people at the beginning. For example, the first purchase of bitcoin in May 2010 was $25 pizza purchased by 10000 BTC, and the price of each bitcoin rose to $1200 in more than three years by the end of 2013

Amazon will launch digital currency project in Mexico. Amazon is recruiting software development managers for digital and emerging payments (DEP) to develop new payment procts that will enable customers to convert cash into digital currency
the digital and emerging payments sector intends to launch the proct in Mexico first. The follow-up will be extended to Brazil and India. It is reported that the digital currency project will completely focus on payment services in emerging markets
