1. In recent years, blockchain digital assets represented by bitcoin have become popular all over the world. Financial institutions, technology companies, investment companies and other participants at home and abroad have invested a lot of human, material and technical resources in the research, development, design, testing and promotion of blockchain digital assets. In order to realize the main characteristics of "four can and three can't" of blockchain digital assets, we can build the core technology system of digital assets by relying on 11 technologies of security technology, transaction technology and trusted guarantee technology. First of all, security technology is used to ensure the fluidity, storability, controllable anonymity, unforgeability, non repeatable transaction and non repudiation of blockchain digital assets. digital currency security technology mainly includes basic security technology, data security technology and transaction security technology. Basic security technology includes encryption and decryption technology and security chip technology. Encryption and decryption technology is mainly used in currency generation, secret transmission, identity verification and other aspects of digital assets. The establishment of a perfect encryption and decryption algorithm system is the core and foundation of the digital assets system, which needs to be customized and designed by the national password management organization. Security chip technology is mainly divided into terminal security mole technology and smart card chip technology. Digital assets can be traded in the form of mobile terminal based on terminal security mole. As the carrier of secure storage and encryption and decryption operation, terminal security mole can provide effective basic security protection for digital assets. Digital asset system trading platform blockchain technology research and development of data security technology, including data security transmission technology and secure storage technology. Data security transmission technology transmits digital asset information through ciphertext + MAC / ciphertext + hash to ensure the confidentiality, security and non tamperability of data information; Data security storage technology stores digital currency information by means of encryption storage, access control, security monitoring, etc., to ensure the integrity, confidentiality and controllability of data information
transaction security technology includes anonymous technology, identity authentication technology, anti plicate transaction technology and anti-counterfeiting technology. Anonymity technology realizes controllable anonymity of digital assets through blind signature (including blind parameter signature, weak blind signature, strong blind signature, etc.) and zero knowledge proof; The identity authentication technology verifies the user's identity through the authentication center to ensure the validity of the digital asset trader's identity; The anti plicate transaction technology ensures that digital assets are not reused by means of digital signature, serial number and time stamp; Anti counterfeiting technology ensures the authenticity of digital assets and transactions by means of encryption and decryption, digital signature and identity authentication. Secondly, the online transaction and offline transaction of digital assets are realized by transaction technology. Digital asset trading technology mainly includes online trading technology and offline trading technology. As a legal currency, digital assets should not be rejected by any unit or indivial, and can be traded online or offline. Online transaction technology realizes online transaction of digital assets through online device interaction technology, online data transmission technology and online transaction processing; The off-line transaction technology realizes the off-line transaction of digital assets through the off-line device interaction technology, off-line data transmission technology and off-line transaction processing technology. Finally, trusted guarantee technology is used to provide a safe and reliable application environment for the issuance, circulation and transaction of digital assets in blockchain. Digital asset trustworthiness assurance technology mainly refers to trusted service management technology. Based on trusted service management platform (TSM), it ensures the security and trustworthiness of digital asset security mole and application data, and provides security chip (SE) and application life cycle management function for digital asset participants. Trusted service management technology can provide application registration, application download, security authentication, authentication management, security evaluation, trusted loading and other services for digital assets, which can effectively ensure the security and credibility of digital assets system
what is blockchain? Blockchain technology, also known as distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in database records. Blockchain technology development blockchain technology development what is a blockchain system? Blockchain system is a database system with integrity.

2. Digital 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. Digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

4. To enter the field of digital currency, you only need to remember the names of the top 100 market value digital currencies or reliable currencies of the operation team, such as eth, XRP, EOS, LRC, BTM, LRN, mana, NAS, HT, etc.

5. You're right about little monsters, but boss is different.
CQ No.1 cuts small ones first, if FS can be controlled, it can be controlled. If DZ is not controlled well, it needs to interrupt the treatment of little monsters.
boss No.2 has a skill & quot; Rebellion & quot; Many melee players don't notice and kill their teammates or even MT by mistake. No.2 will call helldogs, which burn blue very badly. However, DZ doesn't care, but usually give SS or MT to hold No.3, and pay attention to the fire on the ground, and don't stand in front of the boss to output

Pt No.1 has nothing to pay attention to
No.2 DZ wants to play the ball released by boss, Play 4 instant cloaks in a row
No.3 is similar to PVP t good MS monster's treatment until the blind throw is good
No.4 interrupts boss's fireball skill, avoids the infernal flame, and works hard after the Phoenix turns into an egg. In the second stage, everyone flies. Let's give 3 purple electric balls DPS to the remote player

6.

f=N μ N is the positive pressure, that is, the pressure acting on the contact surface, μ It is the dynamic friction coefficient, which refers to the influence factors of the roughness of the contact surface on the friction. Or use the balance f = f; It's only used when it's stationary or moving in a straight line at a constant speed, but it's the most used in junior high school

the so-called friction is the force that hinders the relative motion of the object, and the direction of friction is opposite to the motion direction or relative motion direction of the object. The conditions of friction are as follows:

(1) two objects must contact each other

(2) there was extrusion between two objects

(3) there is a tendency of motion or relative motion between two objects

If an object is stationary on a horizontal plane, it will not be affected by friction if it is not pushed or pulled. If thrust or pull is received, it belongs to the category of static friction. The size of friction is equal to that of pull or thrust, and has nothing to do with the gravity or pressure of the object. Only the maximum static friction is related to the pressure or gravity on the object

if the object is not pushed by 10N force, the object will be subjected to static friction, which is equal to the thrust. Just push with 15N force, and the friction force on the object is the maximum static friction force. If the thrust force is increased later, the friction force will not change. Theoretically, the sliding friction of objects is less than the maximum static friction, but it is generally considered that they are equal

The friction force is f = 15-10 = 5N

extended data:

methods to increase beneficial friction

(1) increase the roughness of contact surface

(2) increase the pressure

(3) change rolling friction into sliding friction

(1) replace sliding friction with rolling friction

(2) make the contact surface separate [form a layer of air cushion or magnetic suspension on the contact surface of the object]

(3) decrease the pressure

(4) rece the roughness of the contact surface

In engineering technology, people often rece friction by applying lubricating oil. The science of this problem is called tribology, which is a branch of mechanical manufacturing

If two objects, which are in contact with each other and squeeze each other, but relatively still, only have a relative sliding trend under the action of external force, but do not have relative sliding, then the force between their contact surfaces hindering relative sliding is called "static friction". When the static friction increases to the maximum, the object will move

size: the static friction varies according to the external force, but there is a maximum value, which is called the maximum static friction. The maximum static friction is slightly greater than the sliding friction

direction: tangent to the contact surface, opposite to the direction of relative motion trend

On the basis of a large number of experiments, G. amunton and C. - A. de Coulomb proposed the following law of friction in 1699 and 1781:

① the friction between two objects in contact does not exceed a certain maximum value, which has nothing to do with the size of the contact area

(2) the maximum value of friction is proportional to the normal pressure n between two objects

(3) the direction of friction is opposite to the sliding direction of the object, and its magnitude is directly proportional to the normal pressure n between the two objects

the above conclusion is only a rough empirical rule, but because it was found in the early days of mechanical science, it was called the law of friction, also known as Coulomb's law

7. No, the central bank has not issued digital currency yet< At present, digital currency is still in the stage of demonstration. Based on the research experience of digital currency at home and abroad, combined with the existing technical system and business scope of UnionPay, the feasibility of UnionPay network supporting legal digital currency is studied and demonstrated< < br > < br > since its establishment, under the leadership of the people's Bank of China, China UnionPay has successfully completed the historical mission of "universal networking" and successfully created its own brand, which has played an important role in serving economic and social development, improving people's livelihood, enhancing the level of financial services, and promoting the construction of China's modern payment system< Br > < br > for details, please check the official website or contact UnionPay customer service< br>

8. It's a scam. China UnionPay has no authority and no need to engage in digital currency

9. UnionPay standard card, starting with 62<

the following is the information in this respect:
what is UnionPay standard card

the most direct difference between UnionPay standard card and bank card issued in the past is the difference in the top six digits of card number. The first six digits of the bank card number are used to indicate the issuing bank or institution, which is called "bank identification number" (abbreviated as "bin"). UnionPay standard card is jointly issued by various domestic commercial banks (including postal savings and credit cooperatives), which conforms to UnionPay business specifications and technical standards. The card has a "UnionPay" logo in the lower right corner of the front (at present, the newly issued UnionPay standard card must have a new international UnionPay logo, while the newly issued non UnionPay standard card uses the old universal UnionPay logo) The top six bank cards with 622126 to 622925 card numbers are national brands shared by the card instry of Bank of China (5.64, - 0.03, - 0.53%). In addition, some member institutions use bin issued bank cards which are independently applied to the international organization for Standardization (ISO), with the "UnionPay" logo on the card face. After testing, they meet the business and technical standards of China UnionPay, and have signed an agreement with China UnionPay, they are also included in the management of UnionPay standard cards< Background of issuing UnionPay standard cards in 2000, the people's Bank of China organized and formulated a series of business specifications and technical standards for bank cards in order to promote universal networking. Among them, "bank card issuing bank identification code and card number" stipulates that all kinds of RMB cards issued and used in China must use "9" prefix bin. The regulation lays a foundation for standardizing and unifying the issuance, use and networking of bank cards in China

with the rapid development of China's bankcard instry and the increasing international exchanges, cardholders' demand for overseas payment is increasing. According to the regulations of the international organization for Standardization (ISO), bank cards with "9" prefix bin can only be used in China. This means that after the RMB is freely convertible, a large number of "9" prefix bin cards issued by domestic card issuers may not be used abroad at that time“ The contradiction between the limitation that the bank card with "9" prefix bin can only be used in China and the payment demand of the majority of cardholders for overseas cards is graally emerging

in order to promote the healthy and sustainable development of the national bankcard instry, safeguard the long-term interests of the card issuing institutions, and overcome the limitations of the overseas use of the "9" prefix bin bankcards, under the guidance and help of the people's Bank of China, in 2002, the, On behalf of domestic card issuers, China UnionPay has applied to ISO for 800 international standards bin (622126-622925) which are popular at home and abroad. After obtaining the approval from the people's Bank of China on the use of UnionPay international standard card issuing bank bin number, in July 2003, China UnionPay issued the letter on the use of UnionPay international standard card issuing bank bin number to its member institutions, and in order to standardize and reasonably allocate, use and manage UnionPay International standard bin number and the widely used "9" prefix bin number, China UnionPay has issued the Interim Measures for the allocation and management of bin numbers of UnionPay identification cards. Thus officially launched the allocation and use of UnionPay international standard "62" prefix bin number, and promoted the member institutions to start issuing UnionPay standard cards, that is, bank cards with "UnionPay" logo, and the top six card numbers adopt UnionPay international standard "62" prefix bin number. The card is in line with China's unified business norms and technical standards. It is a high-quality, international national bank card brand with independent intellectual property rights in China.
