Borrowing computing power

1. Dog coin has been controversial since its birth. Some people say it is the most popular competitive coin, while others say it is a joke

in fact, virtual coin players with a little common sense all know that dog coin has the following fatal defects:

1. First of all, the code of doggie coin is completely copied from Leyte coin. The wallet of doggie coin in the early days has LTC words; Secondly, the founder of dogcoin left the development team in April 2014 and announced twice to quit dogcoin community; Thirdly, up to now, dogcoin still does not have a stable development team. Most of the online volunteers who joined dogcoin development team in the early days have quit. After the founder of dogcoin announced to quit dogcoin community again in March 2015, the development work actually stagnated

2. Dog money has no support of calculation power, that is to say, it has no real value, and its price performance is purely the result of speculative market game. In September 2014, in view of the collapse of computing power, doggy coin abandoned the mining mode and implemented auxpow, that is, to give doggy coin to any mine pool supporting this mechanism. This means that dog money is no longer the object for miners to profit from mining by purchasing equipment. The reason why the mine pool chooses to support dog coin is to get free dog coin< 3. There is eternal inflation. Under the background that most virtual currencies choose a fixed total amount, dog coin is set to increase by 5.2 billion every year, which makes it face serious inflation pressure. Because the new dog coin is given to the mine pool for free (the gift mechanism may be cancelled at any time), the miners will not have any feelings for the dog coin, they will only sell all the new mines. Inflation setting is an innovation of the founder of dog coin, but it completely violates the pricing principle of virtual coin: that is, under the premise of fixed total amount, through periodic halving, let the computing power and price reach a balance, so as to form a reasonable pricing mechanism. Dog money does not abide by the principle of fixed amount, and now even the computing power has been given up, indicating that it is not a standard virtual money

4. Illegal use of the logo registered by ultra Pro company may be prohibited at any time. As we all know, the dog coin borrowed the well-known Chaigou's head picture from the Internet. The "foundation" established a year later claimed to be trying to rush to buy Chaigou's head picture. The effect was just to comfort the fans. At present, ultra Pro company tacitly allows dog coin to borrow its logo, but it may be withdrawn at any time

5. Chinese speculators have completely dominated dog currency trading, and the trading volume of domestic exchanges accounts for 90% - 95% of the global total. It can be said that dog coin has been fully accepted by the Chinese, and the degree of nationalization is far higher than bitcoin, reborn coin, bitstock, and even higher than Leyte coin. The terrible thing is that Chinese speculative market is seriously separated from foreign community culture. The Chinese controlled the trading volume and chips, but never went deep into the foreign community of dog coin. They not only did not participate in any development of dog coin, but also completely ignored the tip and charity culture of foreign dog coin. Chinese speculators regard foreign communities as "idiots" who constantly create favorable conditions. Foreign communities regard Chinese speculators as the cancer of price manipulation. This is the separation of the interests of speculators and currency experimenters, which is inexcusable and irreconcilable

6. At the price of 1%, the main value of 100 billion yuan is 100 million yuan, and the annual value of 5.2 billion yuan of new mines is 5.2 million yuan. In the off-season, the global daily trading volume of dog coin is only 100000-150000 yuan. In case of systemic risk and large-scale cash out of users, it is impossible to have enough funds to resist the current price. So, where did the money go? The answer is that most of the locked up funds have been taken away by miners, and there is no possibility that these funds will return to the dogcoin market. If you want to get rid of the powder, you can only make a false appearance and cheat the new people to add fresh blood.

2. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
blockchain is the underlying technology of bitcoin. It is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
ICO (initial
coin
offering) is an IPO concept originated from the stock market. It is the behavior of blockchain project to issue token for the first time and raise bitcoin, Ethereum and other common digital currencies
the above is the answer of Heshu Software Co., Ltd. if it is helpful, please adopt it.

3. Always lose? If you have extra money, help him return it. If you don't, it's hard to help him. But if you help him blindly, he may make more efforts to carry out improper operation. The serious point is to connive him to make mistakes, and he may not know how to repent. So it's hard to decide whether to help or not.

4. Based on the decentralized characteristics of blockchain technology, the application of blockchain technology can be said to be more, but at present, the substantive application is still less, mainly applied in the fields of finance, medical treatment, authentication, smart contract, sharing economy, digital assets and so on. For example, Yingtang Zhongchuang's blockchain solution is mainly in the development of data encryption, transaction protection and data security transaction system, while other enterprises are more focused on internal needs.

5. 1、 In teaching, to enable students to understand and master the basic knowledge of computing, which is the premise of improving students' computing ability
primary school students often make mistakes in the process of computing e to various reasons, many parents and even teachers are completely attributed to their children's carelessness. In fact, this is only one of the reasons. To a large extent, it is the lack of comprehensive ability of children in calculation. For example, the basic knowledge such as operation law, operation property, operation law and calculation formula is not mastered or cannot be used reasonably and flexibly. Even though the child is very careful and serious in the calculation, he makes seemingly simple mistakes e to the lack of basic knowledge. In teaching, we can't be in a hurry for success. We need to help students find out the reasons (such as incomprehensible calculation theory, incomprehensible laws, unclear nature, unfamiliar laws, not mastering formulas, etc.), find out the omissions and fill the gaps, clear up the obstacles, and do a good job in basic work for further learning calculation
Second, in teaching, it is necessary to cultivate students' interest in computing, which is the key to improve students' computing ability
Einstein once said, "interest is the best teacher.". Confucius also said: "those who know are not as good as those who know well, and those who know well are not as good as those who are happy.". They all talked about the importance of interest. In the teaching of computing, we should stimulate students' interest in computing, let them fall in love with computing and be willing to do it. Only in this way can our teaching of computation be successful. Therefore, we should combine the content of teaching, pay attention to the diversification of training forms, teach in fun, so that the boring teaching of computing is full of vitality. For example, we can use multimedia, cards and other available learning aids and teaching aids to train students in such ways as visual calculation, listening calculation, snatching calculation, in-game calculation, calculation competition and self-made calculation, so as to fully mobilize students' enthusiasm, change students' passivity into initiative, and graally form a lasting interest in calculation
thirdly, in teaching, we should cultivate students' good computing habits, which is the guarantee of improving their computing ability
good computing habits directly affect the formation and improvement of students' computing ability. When doing the calculation problems, some students often have the attitude of contempt. Some calculation problems are not unable to do, but e to the bad habits of insufficient concentration, ing wrong problems, careless calculation, not checking calculation, etc. Therefore, in the teaching of calculation, it is also very important to pay attention to the cultivation of students' good calculation habits. In teaching, we should try our best to make the students form the habit of concentration, careful calculation, careful ing, conscious inspection, conscious estimation and checking. In addition, teachers should strengthen the guidance of writing format. The standard writing format can help students to prevent wrong writing, missing writing numbers and operation symbols, rece the chance of error, and improve the accuracy of calculation
Fourth, in teaching, we should strengthen practice, which is the magic weapon to improve our computing ability
Confucius said, "learn while you learn", "review the old and learn the new", which shows the necessity of practice. Only on the basis of mastering the calculation method, strengthen the practice, can we improve the speed and accuracy of calculation. Only in this way can we realize the knack of calculation and improve the ability of calculation in an all-round way. Of course, we should pay attention to the diversity of training strategies and methods, so as not to cause students' boring mood. For example, the training content should have levels: basic training (the purpose is to master the rules, operation laws, operation properties, calculation formulas, etc.); Targeted training (the purpose is to correct where students are most likely to make mistakes); The purpose of special training is to improve the speed and accuracy of calculation by strengthening memory and remembering commonly used calculation values. For example: the proct of the approximate value of PI 3.14 and one digit, the simplest fraction with denominator of 2, 4, 5, 8, 10 and the interaction of decimals, etc.) Training methods should be diverse, such as: competition, can improve speed; Game style, can improve interest and so on. There are many ways of training, such as: using multimedia; Use simple teaching aids and learning aids (self-made calculation cards, counters, playing cards, etc.)< In teaching, we should strengthen the training of oral arithmetic, which is a shortcut to improve the ability of calculation
oral calculation is the basis of calculation. The strength of oral calculation ability directly affects the speed and accuracy of students' calculation, so we should pay attention to the cultivation of oral calculation ability. First of all, classroom teaching should avoid rigid and single. It can be used in various forms. For example: the form of game can be used in the junior grade: such as "driving a train", "looking for friends", "looking for house number", "sending a letter", "right password", "winning the red flag", "breaking the barrier", etc; The middle grade can use the mental arithmetic board, the mental arithmetic table, the card, the slide or the game to carry on the training; Senior training methods can be named answer, rush answer, all answer, listen to count, count, etc; If we use the above different forms of training methods, if possible, adhere to the appropriate oral arithmetic training before each class, I believe it will be able to quickly improve students' computing ability< Sixth, encourage students to use oral arithmetic in life, which is an essential way to improve students' oral arithmetic ability
we should encourage students to use computing knowledge in our life, so as to make students have a sense of achievement and obtain pleasure. In this way, students will pay more attention to computing and mathematics, so as to improve their interest in learning mathematics. We know: computing is the most widely used in our life. Teachers can get the cooperation of parents, and often let students consciously participate in the calculation of shopping, car ride, travel and other expenses. This can not only improve students' awareness of the application of oral arithmetic, but also improve students' computing ability. It's really a double win with one stone
in short, computing teaching is a long-term and complex teaching process, and it is not a matter of one day to improve students' computing ability. It needs the joint efforts of teachers, parents and children to achieve good results. I hope that teachers, in the future in the teaching of computing bear fruitful results.

6. Calculation is an important basic knowledge in primary school mathematics, which runs through the whole process of primary school mathematics teaching. Whether a student's calculation ability is strong or not is directly related to his interest and effect in learning mathematics. Therefore, it is very important for students to learn calculation well and form a certain calculation ability. As teachers, how can we change the current situation that most primary school students' computing ability is very weak? Let's talk about my personal opinions:
first, in teaching, to make students understand and master the basic knowledge of computing, which is the premise of improving students' computing ability
primary school students often make mistakes in the process of computing e to various reasons, many parents and even teachers are completely attributed to their children's carelessness. In fact, this is only one of the reasons. To a large extent, it is the lack of comprehensive ability of children in calculation.

7. Whether a student's computing ability is strong or not is directly related to his interest and effect in learning mathematics. Therefore, it is very important to enable students to learn computing well and form a certain computing ability
first, interest is the best teacher
in the teaching of computing, we should stimulate students' interest in computing, let them fall in love with computing and be willing to do it. Only in this way can our teaching of computation be successful. Therefore, we should combine the content of teaching, pay attention to the diversification of training forms, teach in fun, so that the boring teaching of computing is full of vitality. For example, we can use multimedia, cards and other available learning aids and teaching aids to train students in visual calculation, listening calculation, snatching calculation, in-game calculation, calculation competition and self-made calculation. Graally formed a lasting interest in computing< The second is to cultivate students' good habit of calculation.
when doing calculation problems, some students tend to have an attitude of contempt. Some calculation problems are not unable to do, but are caused by bad habits such as insufficient concentration, wrong ing, careless calculation and no checking. Therefore, in the teaching of calculation, it is also very important to pay attention to the cultivation of students' good calculation habits. In teaching, we should try our best to make the students form the habit of concentration, careful calculation, careful ing, conscious inspection, conscious estimation and checking. In addition, teachers should strengthen the guidance of writing format. The standard writing format can help students to prevent wrong writing, missing writing numbers and operation symbols, rece the chance of error, and improve the accuracy of calculation
Third, students understand and master the basic knowledge of computing, which is the premise of improving students' computing ability
in teaching, we should help students find out the reasons (such as incomprehension of calculation theory, incomprehension of laws, incomprehension of nature, incomprehension of laws, incomprehension of formulas, etc.), find out the omissions and clear up the obstacles, In order to further learn the basic work of calculation
in a word, the improvement of computing ability is not something that can be achieved overnight, but it is something that has been trained step by step over time. Don't feel that computing is simple and boring, and develop a good habit of loving, being good at and checking computation.

8. The research of this problem should be based on experiments. You can find some people to do experiments, let one group calculate the same problem with pen, and the other group calculate the same problem with calculator. Look at the speed results of the two, calculate more problems, and find more people to expand the sample size and increase the reliability of the test results
intuitively, it seems that using a calculator is bound to improve the user's computing ability, but in fact, the result is not certain. I remember that when I was in the second grade of junior high school, I competed with my classmates for a series of continuous calculations. I used a pen and they used a calculator to see who would finish the calculation first. As a result, I finished the calculation first, but my classmates pressed the wrong number keys on the calculator many times, And the calculator display is not intuitive enough, leading to repeated rework, but slower than my calculation. It can be seen that whether a calculator can improve a person's computing ability is related to the accuracy and speed of key pressing of the calculator, the contrast between them and the user's written calculation ability, and the complexity of the problem itself
Senior Two students should have learned the least square method. You can establish the corresponding regression line for research, such as establishing the regression relationship between a person's computing speed and his proficiency in using the calculator. Of course, the specific research steps still need to be designed by yourself.

9. At present, if you don't go abroad, you'll never find it. China has cut off social networks like Facebook YouTube. Only foreign gods can help you Note: you have to go abroad. This kind of red stone can't be easily found on social networks like YouTube. You need to search many foreign software to make it possible.)
