Maintenance and management of digital currency

1. Bet in wechat group? No app? Now many news reports about wechat group fraud. It's too unsafe. When the wechat group is disbanded, who do you want to get the money from.

3. As for the so-called drainage brush with an investment of 23000 yuan and a monthly income of several thousand yuan, after analysis and understanding, this is definitely another pyramid selling mode of pulling people's heads
the people who have been brainwashed are all those who are among them. Every day, it's like beating chicken blood. How much money is easy to earn and how much money is safe to go in and out freely. Ask yourself, there's such a good thing. What's the class you're going to work for? If the whole family comes in, it's tens of thousands a month. Ha ha, there are also those people who pull you in, If you think about it with your toes, why doesn't he bring in his family's seven aunts and eight aunts with such good money? What are you doing? Are you familiar with him? It's just for the sake of promoting the group leader to earn management fees, and then instigate you to promote the group leader, and then instigate you to promote the group leader... If this goes on repeatedly, it's not the MLM model of promoting the group leader
then, let's talk about the so-called currency appreciation! In fact, it's the left hand selling and the right hand buying, which are all operated by these top people. Today they ask you to agree to buy, and later they ask you to sell in a unified way. The prices are all set by them. In four days, they will increase a little, and go back and forth. The platform earns handling fees, but they don't have to pay. The reverse handling fees are all paid by the people below
secondly, the people who come in, in fact, the people who come in later are leeks. You have to invest money to make money. If you come in alone, you can only get back your principal for at least 10 months. If you lose once in 10 months, you will go back to before liberation. If you win, OK, This is their continuous cultivation of leeks. Ha ha! In this way, leeks constantly come in, in order to maintain the so-called dividend profits. So as long as this one is checked or no leeks come in, no one will buy the coin and no one will manage it, your 30000 will be gone, and the rest will be just a bunch of so-called numbers
what they call "retail investors" are the leeks that are not brainwashed every day? The people who come in will open an account, and then buy money through their designation, so that the money can circulate, so once no one comes in to take the order, it will collapse
some people also asked that there is a dividend every four days. There are also people who have made millions of money. In fact, what they share now is only your own money. Those who can make millions of money are those who pull people's heads, and those who really don't pull people's heads. So far, there are several people who earn back the principal
you've been brainwashed, and you've been dragged by your friends, classmates, etc. In the future, you don't even have a friend to do...
how many people want to make big money and soft money all day long now, and how many people are not losing money, even the principal, the house and the car are gone with... If you are not greedy for these blockchains, the wolf of digital currency won't have a chance to bite you! Go to your class and do your work steadfastly. You want to get rich overnight without any effort and earn tens of thousands a month. In the end, you have to lose your own savings

4. 1 the framework of legal digital currency needs the participation of non bank payment institutions
there is no unified concept of legal digital currency. The Bank of England defines "digital currency" as "a payment method existing only by electronic means... Which can be used to purchase physical goods and services"... Including "private digital currency" and "digital currency issued by the central bank". Further than the Bank of England, Yao Qian, director of the digital currency Research Institute of the people's Bank of China, made clear the multiple connotations of the central bank's legal digital currency in several public speeches: legal and encrypted credit currency, adopted a series of algorithms, and derived more intelligent functions in the payment function
to this end, the central bank has designed a system architecture of "one currency, two warehouses and three centers", that is, taking digital currency as the center, designing the issuing library and deposit library, matching the certification center, big data analysis center and registration center. The central bank's digital currency is issued by the central bank and circulated in the commercial bank's account. The issuing inventory is put into the people's Bank of China to deposit the digital currency. The deposit bank is the database of the commercial bank to deposit the central bank's digital currency. The authentication center manages the identity of institutions and users in a centralized way; The registration center completes the whole life cycle and ownership registration of the central bank's digital currency; The big data analysis center achieves the goals of anti money laundering, anti terrorist financing, index detection and analysis
as an important node in the framework of legal digital currency, commercial banks play an important role in the circulation of central bank's digital currency. In the case that China's non bank payment institutions have occupied a certain market share, it is a better choice for non bank payment institutions to participate in the framework of digital currency operation as a supplement to commercial banks. The reasons are as follows: first, third-party payment institutions can help commercial banks realize the promotion of legal digital currency. Within commercial banks, there is a competitive relationship between legal digital currency and physical currency. The public tends to convert the digital currency in cash account into traditional currency in exchange for income, so it is difficult to achieve the goal of promoting digital currency by commercial banks; Second, the third-party payment institutions can avoid the repeated construction of payment application scenarios by commercial banks. Different from non bank payment institutions, the current payment scenarios of commercial banks are relatively lack of diversification, which will lead to a waste of resources and the rich experience accumulated by non bank payment institutions; Third, the third-party payment institutions can appropriately rece the operating costs of commercial banks. On the one hand, commercial banks need to upgrade the necessary software and hardware for the central bank's digital money service; On the other hand, we should continue to do a good job in traditional RMB deposit and withdrawal services. The simultaneous operation of the two systems will increase a lot of human and material costs. Fourth, the third-party payment institutions can promote the construction of payment instruments and channel integration of commercial banks. In the framework of legal digital currency, the single payment instruments and complex payment channels provided by commercial banks may rece the enthusiasm of the public to use legal digital currency
2 the emergence of legal digital currency reshapes the role of non bank payment institutions
in the process of cooperation with commercial banks, all kinds of non bank payment institutions play four roles. The first is the role of account manager. Non bank payment institutions can not operate deposit and loan business, and the amount in their payment account is not a deposit, so it is easier for the public to accept the role of non bank payment institutions as "digital wallet". At the same time, non bank payment institutions have rich experience in the development and operation of digital currency wallets and their terminals, which is concive to the smooth management and use of central bank's digital currency, and there is no need to worry about the risk of misappropriation of funds by non bank payment institutions. The second is the role of payment service provider. Non bank payment institutions have a lot of experience in scenario development and operation, including mobile payment, cross-border payment and rural payment, and relatively large market share of scenario based payment. On the one hand, powerful non bank payment institutions can develop a variety of procts based on Intelligent legal digital currency to meet the needs of users' exchange, payment, storage and related derivatives; On the other hand, non bank payment institutions can make use of various scenarios to promote the use of legal digital currency. For example, when consumers want to invest through the central bank's digital currency, non bank payment institutions, with the experience of traditional currency investment and payment services and upgraded digital wallet, can be fully competent as the special payment service provider of digital currency investment. Third, the role of system construction service provider. NPC, the core of national payment and settlement system, and CCPC, the core of provincial payment and settlement system, will continue to play an important role in the framework of legal digital currency. In the long-term coexistence of legal digital currency and traditional currency, NPC and CCPC will be double important nodes. Non bank payment institutions with strong technical ability can be used as secondary verification nodes under the framework of legal digital currency to supplement the multi center and distributed system architecture and continue to dock with NPC and CCPC
3 technical connection between non bank payment institutions and legal digital currency system
the innovation of non bank payment institutions is accompanied by the connection with legal digital currency system, covering the whole process of digital currency generation, storage, use and withdrawal. In this process, the first thing to solve is the docking of basic layer technology and transaction mole. The docking of basic layer technology is reflected in three aspects. First, in terms of basic security technology, non bank payment institutions, as providers of mobile terminal transaction forms, need to apply terminal security mole technology, dock with unified encryption and decryption system, provide carriers for secure storage and encryption and decryption operations, and provide effective basic security protection for digital currency. Secondly, in the aspect of data security technology, non bank payment institutions, as a part of the whole payment system, should adopt the official unified ciphertext + MAC / ciphertext + hash technology to transmit digital currency information, so as to ensure the confidentiality, security and non tamperability of the information. Thirdly, in the aspect of transaction security technology, non bank payment institutions, as the advanced nodes participating in bookkeeping, adopt blind signature technology to ensure the controllable anonymity of digital currency in the process of transaction, and eliminate the possibility of repeated payment through serial number, time stamp and other ways; And through encryption and decryption, digital signature, identity authentication and other anti-counterfeiting ways to ensure the authenticity of the transaction
when docking with the transaction mole, non bank payment institutions should do the following: first, docking with the certification center to obtain relevant digital certificates and user identity information; Second, connect with the trusted service management mole to obtain the use function of digital currency; Third, connect with the issuing system and storage system, and apply for and exchange digital currency through the bank treasury; Fourth, connect with the transaction communication mole to ensure that users can realize online payment through the transaction network in the intelligent terminal based on online transaction communication; Fifth, connect with the registration center, notify and record the flow of digital currency transactions, so as to complete the registration of the central bank's digital currency generation, circulation, checking and extinction process
4 scenario docking between non bank payment institutions and legal digital currency system
scenario docking of non bank payment institutions is based on the transformation of their own roles. Legal digital currency is algorithmic currency and intelligent currency, so business innovation and scenario expansion are the proper meaning of legal digital currency system. Non bank payment institutions can achieve scene docking mainly in four aspects
first, enabling the financial instry and defusing the limitations of financial scenario services. At present, there are some limitations in financial scenario service, such as business modeling is not universal, different agents have different management requirements, and the system docking cost of participants is high. Non bank payment institutions connect with the underlying technology of legal digital currency, and through the research and development of smart contract, establish behavior information such as capital flow, trigger conditions, value change rules, revenue right registration, and corresponding capital information (amount, account, currency, etc.) to resolve the existing limitations of financial scenario service. Non bank payment institutions use the atomic properties of digital currency and the atomic transactions of smart contracts to "assemble" into a business model. It does not need to develop a separate platform for different business scenarios, and avoids the monopoly of the instry platform and the non disclosure of information
Second, expand the use scenarios and improve the user experience. Non bank payment institutions can continue to expand the use scenarios according to the characteristics of legal digital currency on the basis of the existing rich payment scenarios, so as to meet the needs of users' exchange, payment, storage and related derivatives. At the same time, through the aggregation application, users can use the app of non bank payment institutions to dock a large number of scenarios and services
thirdly, improve the security of funds and create a universal digital wallet. Non bank payment institutions can provide digital wallet services, create digital wallets that meet security standards through their own technology, and ensure the security of users' funds. Alternative methods include: the central bank and non bank payment institutions cooperate to develop a unified universal digital wallet application, or authorize several qualified non bank payment institutions to provide universal digital wallet services. The digital wallet can realize the mutual exchange between the user's funds in various commercial banks and the legal digital currency even in the self owned accounts of non bank payment institutions. From the perspective of implementation, at the same time, the traditional account system of commercial banks can also bind the digital currency wallet of non bank payment institutions, so as to achieve the joint management of traditional accounts bound with digital currency wallet
Fourth, help cross-border settlement and build a safe and reliable cross time zone alliance chain. Non bank payment institutions can deeply participate in the cross-border payment system of legal digital currency. Cooperation with commercial banks and central banks can be achieved in at least two aspects. First, payment standards and tools are available. Non bank payment institutions participate in the research and establishment of standards and tools to realize the possibility of technical docking. Second, cross border payment system. The business system led by the central bank and participated by commercial banks and qualified non bank payment institutions will help to realize efficient cross-border payment
5 the legal framework of non bank payment institutions and legal digital currency is connected
a perfect legal system is an important guarantee for the operation of the digital currency system. There are several key questions to answer. First, how to determine the ownership of legal digital currency? This is the basis of all legal acts of legal digital currency. The first way of thinking is that legal digital currency is intangible. As a special movable property, it is applicable to the provisions of the property law. For example, Liu Xiangmin, director of the Department of articles and law of the people's Bank of China, believes that "to solve the problem of ownership transfer of digital currency, we should also focus on the publicity of ownership." The second idea is that digital currency is an electromagnetic record, which is applicable to the law of data transfer and transaction. The essence of digital currency is electromagnetic recording, and the transfer of electromagnetic recording content is recorded in the node of digital currency technology architecture. The change of node records is taken as the standard of ownership transfer. Second, how to protect personal information security? Personal information security is a basic problem in the era of digital economy. In addition to legislation to improve the level of technical security, we should also make clear the main types of legal digital currency system

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 = 8

for 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 shield

arrangement 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 layer

Nowadays, people's lives have undergone earth shaking changes. Shopping methods and work habits are being overturned. From the cash age to the Internet age, code scanning payment is becoming more and more convenient in all aspects, and the zero cash mode of clothing, food, housing and transportation has been fully realized. It must have never been thought about before. Now it is actually a reality, but this way will also say goodbye, Did you think of it? In an era of progress, there will be constant updates and iterations

according to the relevant reports, the next digital currency will be carried out in 28 regions such as Chongqing. According to this form, it will become a reality in the next few years. After the popularity of digital money, there will also be other ways of payment, but there are always lots of people who are willing to try new things. After experiencing the comparison, WeChat Alipay's two-dimensional code payment may really have to meet again. It is more secure than that. It does not need to bind the bank card, nor does it need the help of the third party platform. It's more convenient

which way do you prefer? Welcome to discuss

7. These days, silver world how also can't log on, there are digital currency, should not be running

8. Management and restraint depend on big policies

With the advent of digital currency, the encryption algorithm of currency is becoming more and more important. What are the types of passwords

classical cipher types mainly include transposition cipher and rearrangement of alphabetic order messages. For example, "Hello world" becomes "ehlol owrdl"

Diffie Hellman and RSA algorithms have been widely used except for the first public example of high quality public key algorithms. Other asymmetric key algorithms include Cramer schup cryptosystem, ElGamal encryption and various elliptic curve techniques

some well-known cryptosystems include RSA encryption, Schnorr Signature, El Gamal encryption, PGP and so on. More complex password systems include e-cash system, signcryption system, etc. Now more cryptosystems include interactive proof systems, such as zero knowledge proof, which is used for secret sharing

for a long time, information collection and law enforcement agencies have been interested in cryptography. The importance of secret communication is self-evident. Because cryptography promotes privacy protection, it also attracts great interest of cryptography supporters. Therefore, there is a history of controversial legal issues around cryptography, especially since the emergence of cheap computers makes it possible to widely use high-quality cryptography

nowadays, cryptocurrency transactions are semi anonymous, which makes them very suitable for a series of illegal activities, such as money laundering and tax evasion. However, the proponents of cryptocurrency often attach great importance to the anonymity of digital currency and think that it can protect the privacy of users. Some cryptocurrencies are more private than others

Cryptocurrency is a new type of digital asset, which is based on the network distributed on a large number of computers. This decentralized structure enables them to exist outside the control of the government and central authorities. The term "cryptocurrency" also comes from the encryption technology used to protect the network

blockchain is an organization method to ensure the integrity of digital currency transaction data, and it is an important part of many cryptocurrencies. Many experts believe that blockchain and related technologies will subvert many instries, including finance and law. Cryptocurrencies have been criticized for many reasons, including their use for illegal activities, exchange rate fluctuations and the vulnerability of the infrastructure that underpins them. However, digital currency is also praised for its portability, divisibility, anti inflation and transparency
