Currency code 14
2019 August 21st, the official account of WeChat central bank released two articles on digital currency.
1. Litecoin is similar to bitcoin, which is also an encrypted digital currency, and its price has risen sharply recently. It is a P2P open source digital currency, which can be regarded as a branch of bitcoin. However, although lightcoin is based on bitcoin protocol, it does not require very high computing power. It can also be mined using ordinary computers. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
2. Namecoin
namecoin is also based on bitcoin, which is another branch of open source. Namecoin is a distributed DNS protocol -- generally speaking, it can transform the website name (such as ifeng. Com) that can be understood by human into the address that can be understood by machine. As its own DNS, this kind of currency can operate outside the normal Internet, so it can break away from the control of ICANN
the monetary value and domain name of namecoin are stored in the user's blockchain records, limiting the total number to 21 million
3. Peercoin
peercoin is a peer-to-peer variant of bitcoin, which can improve mining efficiency and security, and improve safeguard measures to avoid group mining. Now, group mining has been considered as a potential defect of bitcoin. According to the statistics of emerging currencies by coinmarketcap.com, peercoin currently ranks fourth in the market value of digital currencies
4. Primecoin
primecoin is a cryptocurrency similar to bitcoin, but it uses a completely independent mining algorithm. Bitcoin uses the hashcash algorithm, while prime coin uses the long Cunningham chains to create the value of money - a sequence of prime numbers named after mathematician AJC Cunningham
in the process of bitcoin mining, as the amount of money goes on, the difficulty will increase sharply. But prime is different. Every time a primecoin is mined, the mining difficulty will increase slightly, and the process is much more stable< 5. Feathercoin
based on the design of litecoin, released in April 2013, can adjust the mining difficulty more frequently than litecoin. Feathercoin will be updated frequently, adding new features and improvements to eliminate malicious mining behavior
6. Novacoin
another P2P digital cryptocurrency. Novacoin is different from most other currencies in that it integrates a protection mechanism in the currency core, which can identify illegal mining activities
the total number of novacoin is limited to 2 billion, which is considerable. If necessary, the total can be adjusted upward
7, infinitech
published in June 2013. A by-proct of litecain. According to the mining situation and the total amount of money, infinite money can frequently adjust the mining difficulty ratio< Megacoin was only released in the fourth quarter of 2013, imitating bitcoin in the early stage. The total number of megacoin is limited to 42 million, which can be mined like other virtual currencies. Its biggest selling point is brand publicity, which other digital currencies lack< It was released in 2013 and is still in its infancy. In the security part of quarkcoin, nine independent loops are deployed and six different algorithms are used.
Generally, the excellent digital currencies are mostly imported procts, such as bitcoin, Leyte coin, ether coin and so on. However, the domestic Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects of European crowdfunding are excellent digital currencies
digital currency (English: digital currency) is an alternative currency in the form of electronic currency. At present, no central bank of any government has indicated that it will issue digital currency, and digital currency does not have to have a benchmark currency and a central bank
it 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 currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography

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
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 manufacturingIf 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 objectsthe 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
at that time, it was on Jin's birthday.
generally, invitation codes cost money.
few people spend so much island money (the virtual currency of the first stop) to buy it for others. An invitation code is more than 300, which is very expensive.
so you can register on December 17.
general members' birthdays, major festivals, The first station will be open for registration on the X anniversary of its establishment and the X anniversary / xxx day anniversary of FT's debut. Just seize the opportunity
The first two English letters are called Guanzi, and the last eight Arabic numerals are called numbers
crown: there are 26 English letters without V and 25 more. There are ten groups from a to j, five groups from klmno, and ten groups from P to Z. These three groups are allocated to each other, perhaps from one group to another, forming nine groups. The batch of RMB printing is in accordance with the order of large group
number: from 00000001 to 100000000 (note eight zeros), there are 100 million copies
extended data
except for 1, 2 and 5 coins, the first set, the second set and the third set of RMB have been withdrawn from circulation, and the fourth set of RMB has been withdrawn from circulation since May 1, 2018. The RMB circulating in the market is the fifth set of RMB; The paper currency in circulation are: 1,5 Jiao, 1,5,10,20,50,100 yuan; There are one dime, five dimes and one yuan in coins
among the five sets of RMB displayed in the China Coin Museum, different from the last four sets, the arrangement of the six characters "people's Bank of China" and the denominations of Chinese characters in the first set of RMB (except for the 1953 version of the 5000 yuan Weihe bridge design voucher) is from right to left, while Chairman Mao proposed that the row names of RMB should be arranged from left to right in 1952, The arrangement of "people's Bank of China" on the RMB has been changed from left to right
