1. From cheap electricity to centralized mining, China's resources and environment provide bitcoin miners with many advantages. In recent years, bitcoin miners have used cheap electricity to expand their business in coal rich regions such as Xinjiang and Inner Mongolia, which are home to the founders of some of the world's leading mining companies
with the rising price of bitcoin, more and more people join the bitcoin mining business. Accordingly, mining consumes more and more energy. Obviously, our government is also aware of this
according to the requirements of the document, regulators require local governments to take measures related to electricity price, land use, tax and environmental protection to guide bitcoin miners to withdraw from the business. According to foreign media reports, regulatory authorities are mainly concerned about the money laundering and financial risks involved in the shutdown policy, but excessive power consumption is also a factor that can not be ignored. In principle, bitcoin mining consumes a lot of power because every time a new bitcoin is proced, it needs to solve the complex mathematical problems through the encryption process performed by a high-performance computer. Mining calculation process is used to verify bitcoin transactions in the blockchain to ensure security, but the disadvantage is that it consumes a lot of energy.

4. 1、 Basic training:
from the psychological characteristics of different ages of primary school students, the basic requirements of oral arithmetic are different. Low and middle grade students mainly add one or two digits. It is better for senior students to take the one digit by two digit mental arithmetic as the basic training. The specific requirement of oral arithmetic is to multiply the number of one digit and the number of ten digits of two digits, and then add the proct of multiplying the number of one digit and the number of one digit of two digits to the three digits, and quickly say the result. In primary school, this training is a sublimation training of abstract thinking of numbers. It is very beneficial to promote the development of thinking and intelligence
Second, targeted training: the main form of the number of senior primary school students has changed from integer to score. In the operation of numbers, the addition of different denominators is the most time-consuming and error prone place for students, and it is also the key and difficult point of teaching and learning
two fractions, the large number in the denominator is the multiple of the decimal. For example, "1 / 12 + 1 / 3", in this case, oral calculation is relatively easy, the method is: the big denominator is the common denominator of two denominators, as long as the small denominator is expanded by multiple until it is the same as the big number, and the denominator is expanded by several times until it is the multiple of another denominator decimal< Third, memory training
the content of senior calculation is extensive, comprehensive and comprehensive. Some common operations are often encountered in real life. Some of these operations have no specific rules of oral arithmetic and must be solved by strengthening memory training. The main contents are as follows:
1
2. The proct of the approximate value of PI 3.14 with one digit and the proct with several common numbers 12, 15, 16 and 25
3. The denominator is the decimal value of the simplest fraction of 2, 4, 5, 8, 10, 16, 20 and 25, that is, the interaction of these fractions and decimals.

5. 1、 Cultivate students' interest in calculation
simple calculation is often boring and students are easily bored. Therefore, according to the psychological characteristics of the lower grade students who are active and competitive, we can use a variety of training forms to replace the previous single form of practice. For example: training with games, competitions, etc; Driving trains, rushing to answer questions, breaking through barriers, etc. Various forms of training, not only stimulate students' interest in learning, but also make every student actively participate, so as to get twice the result with half the effort. Senior students can explain the principle of problem-solving more, let students understand the context of problem-solving ideas, know the reasons for this problem-solving, deepen the understanding, will improve interest< Second, pay attention to the training of oral arithmetic
oral calculation is the basis of written calculation, which requires not only accuracy but also speed. The formation of oral arithmetic skills and the improvement of speed can not be achieved by one or two days of training, but by constant training. In my opinion, the effect of mental arithmetic three minutes before class is very good. Before each class, prepare ten oral arithmetic questions for students to rush to answer, or let students write in a small book, check the answers in a unified way, make a summary every other time, and praise and reward the excellent students. The enthusiasm of students has been improved, and at the same time, they will pay attention to the correct rate. Of course, remember some common values, such as 2 π、 three π、 four π……， 112, 122, 132... And so on, which have a very good effect on speeding up the speed and accuracy of oral calculation< Third, strengthen the training of estimation
many problems in daily life don't need very accurate results, so we can use estimation to solve them. In this way, the speed is accelerated, and it does not affect the actual operation. When encountering such problems, let the students estimate as much as possible. In addition, even in the calculation of accurate results, the estimation will also play a monitoring role. Every time we finish a question, we can use the method of estimation to verify its correctness< 4. Pay attention to quick calculation and skillful calculation. Quick calculation and skillful calculation, that is, we usually say simple operation, the correct use of simple methods, on the one hand, can improve the speed of problem solving, on the other hand, can also make problem solving simple, improve students' self-confidence. The teacher can teach some basic laws first, let the students answer the questions, in the example of some calculation problems, let the students find the appropriate simple method. This requires students to have a clear grasp of the basic law of operation, especially the scope of its application. For example, multiplication has distributive law, but division does not. This requires students to divide by a number into its reciprocal, in the use of distribution law for calculation.

6. Computing power (also known as hash rate) is a measure of bitcoin network processing power. That is, the speed of computing hash function output for computer (CPU). Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second
in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on the computer's random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is the so-called proof of work mechanism (POW)
recently, bitcoin's network computing power has entered the era of P computing power (1P = 1024t, 1t = 1024g, 1g = 1024m, 1m = 1024k). In the ever-increasing computing power environment, the arrival of P era means that bitcoin has entered a new stage of arms race
computing power is a measure of the total computing power of the unit that generates new blocks under certain network consumption. The single blockchain of each coin varies with the time required to generate a new transaction block.

7. Hello, if it's for prevention, you can give 3 injections in 0, 7, 21 days. One needle should be strengthened after one year, and another needle should be strengthened within one to three years. If you are bitten or scratched by a small animal, then according to the situation, some will be given 4 injections, while others will be given 5 injections. Then you have to listen to the doctor.
