1. computing power refers to computing power. 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 computer random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", Unit is written as hash / s, which is the so-called workload proof mechanism pow (proof
of
work)
What does 1p mean
first of all, 1p computing power is equivalent to about 1.05 million g, which means that if you have 1g computing power of the whole network, you can get almost 1.05 million of bitcoin output of the whole network. According to the output of 3800 bitcoins per day, we can see that the daily income of 1g of computing power has dropped to 0.0036 bitcoins, which is about 2.7 yuan according to the current market price. If the electricity cost and mining machinery hardware cost are included, the profit is almost gone
secondly, 1p's whole network computing power seems amazing, but in fact, in a year's time, you will think it's just a pediatrics, because cointera will launch 2p miner in December, and bitmine will launch 4P miner in March next year. If these companies are not put in biochemical weapons by Syria, it should be expected that bitcoin's whole network computing power will reach more than 10p in a year's time, By then, 1g of computing power will only be able to dig 0.00036 bitcoins a day.

2. First of all, understand and firmly grasp the basic knowledge. That is, the basic knowledge related to computing power, mainly refers to mathematical concepts, operation laws, operation properties, operation rules and calculation formulas. It is difficult for students to understand some calculation rules. In teaching, teachers should not be in a hurry for success, but should help students to master basic knowledge as a breakthrough, disperse and break through difficulties. For example, when teaching the addition and subtraction method of different denominator fractions, first of all, let students understand that the denominator is different, that is, the units of fractions are different. If the units of fractions are different, they can't add and subtract directly. When they understand this truth, they can guide students to use the knowledge of general score to change the different denominator fractions into the same denominator fractions, so the problem turns into the addition and subtraction of the same denominator fractions that they have learned
Second, strengthen the practice and basic skills training. In the calculation practice, strengthening the basic skills training is an important step to improve the calculation ability. In addition, in the calculation practice, we should help students summarize some regular things, so that they can skillfully use the basic knowledge to calculate, and constantly improve their calculation ability. In addition, the forms of calculation exercises should be diversified, and the forms should serve the content. However, we should pay attention to the quantity of exercises. We can't do the opposite as long as we don't pay attention to the quantity and quality. Some students lack the spirit of diligent learning, and the calculation itself is boring and lack of plot. When students encounter a large number of questions, they are easy to resist and unwilling to calculate, which can seriously affect students' interest in learning mathematics. In teaching, as teachers, we should simplify the topic selection, Try to find some simple calculation problems to guide students to do abstruse calculation problems
thirdly, cultivate students' good study habits. Good learning habits are the guarantee to improve the accuracy of calculation. First of all, students are required to carefully review the calculation, and do not blindly simplify the calculation without reviewing the operation order, such as 15 + 5 × 5), the students mistakenly calculated it as 20 × Secondly, the calculation process should be strictly standardized. When solving problems, students are required to have standard calculation format, neat writing, clean homework and paper surface. Even the draft should be written neatly and clearly. When students make mistakes in calculation, students should not only check the calculation process, but also find out whether there are errors in the draft. For example; The alignment of digits, whether the carry is added or not. Let the students form the habit of self checking in calculation< Fourth, strengthen the cultivation of the ability of oral calculation.
calculation is the basis of estimation and written calculation. Any four item mixed calculation problem is synthesized by the oral calculation problem of the main road. The correctness and rapidity of oral calculation directly affect the improvement of the calculation ability. When designing oral calculation exercises, we should be targeted, from easy to difficult, and graally improve them, including some simple calculation problems, It is helpful to train students' thinking flexibility to do oral arithmetic exercises frequently.

3. 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.

4. Computing power refers to computing power, which refers to the technical term of "mining" to get bitcoin.
for example, all kinds of mining machines sold by digyi mining have high computing power and low energy consumption, so you can consult.

6. The title of love ecation makes me think about what love is in this diverse world. With this thinking, I trudged with an Italian primary school student to explore an unknown answer. Love, like air, is always ignored by us because it is invisible every day. In fact, its meaning has been integrated into life, just like parents' love, When we are in trouble and no one supports us, it is our parents who are still with us. At night, we don't forget to tell them to go to bed early, I realize that parents all over the world have a deep love for their children. Amrico has a diary that they read and write with their parents, but now many students still have a small lock on their diary. The simplest things are most easily overlooked, just like the deep love between parents and children in this great love, which many people can't feel. If love is a travel, some people may have objections. But love has no end, Happy travel. Just like life, if we regard life as a sentence, people will do heavy work for the sake of one day's release and detachment; On the contrary, if you look at life as a tour, you will feel relaxed and enrich yourself with new things every day. Therefore, you want to go on, even put in enthusiasm, and don't care how long it will last. At this time, this feeling has been sublimated into a kind of love, a kind of love for life, I went into the life of amrico, I went into the life of amrico, and I saw how they learned, lived and loved. In the moving, I found that love contains the pursuit of life. If love is a galloping blood and a jumping heart, then I think it is a noble love for the country; Slogan & quot;, But as a person with conscience, this kind of love should be firmly embedded in our hearts. When I read the moving scenes of Italian people blowing up their legs for their country and defending their homeland, I can't help thinking that our motherland was also soaked with the blood of the Chinese people, Love is great because it is not only for indivials, but also for the dignity and emotion of the whole nation. In the ecation of love, love is compared to many things, which is true and not only these; What is love; There won't be a definite answer, but I have completed my thinking about love - love is great, infinite, great power. Doing housework for my mother this summer, the teacher left a special assignment --- to experience my parents' working life. I'm talking about summer vacation, so I can't let myself be idle. Slowly, used to do some housework, for mom and dad to share. I told my mother about my homework, and my mother also said that your teacher's idea is very good! I'll set up a job for you! And do not only once, you are teachers, a stay on the serious homework, usually do not do. You're going to give me a summer vacation this time. The first is to mop the floor. Just mop it twice. My mother didn't think this job had much weight, so I got an extra job - washing dishes. I will show my hands in the kitchen, and I will take the initiative to wash my parents' feet. I like washing dishes best. Just out of the pot of food on the plate is delicious, and we finished eating, leftovers piled up in the pool, is the resie. The next day when washing dishes, it may be not adapt to it, leftovers taste particularly bad. For this reason, I wear plastic gloves to wash the dishes, and the dishes are full of oil stains. There are also some leftovers lying lazily on the plate and thrown into the garbage can, which makes people cover their nose. I'm just looking forward to it. Wash it quickly. It looks clean on the surface. With such a reluctant mood, I washed the water once or twice. Slowly, I accepted the smell and didn't feel bad. I don't need gloves when I wash the dishes. I'm just imagining that I'm going to bathe the bowls and plates, remove the stains from them, and put on a brand new and clean look. My hands itch when I see my mother cooking. I said to my mother, "let me help you cook today." Then he rolled up his sleeve and washed his hands. I first pour the rice into a small bowl, then pour it into the pot, twist the water tap, connect a small half, and start to wash the rice by hand. After washing the rice three times like this, I pour the water, and then put the rice on the fire to make the water less than one centimeter. At this time, I began to cook. What do I do? By the way, make fish flavored shredded pork! My mother helped me prepare the carrots and asparagus, and also helped me find a small knife. I began to cut the carrots. First, I cut them into pieces, and then cut the carrots into two pieces. The same is true for asparagus and shredded meat. But the shredded meat is a little difficult to cut. When it's all ready, it's time to do it, Pour a little oil, then put the sauce in, stir fry twice, and then put the shredded meat in, stir fry twice, accidentally, my hand touched the pot, I immediately cried with pain, my mother quickly took the shovel, let me use cold water to wash my hands, I thought: cooking this thing looks very common, it is not easy to do it! This reminds me of one thing that happened last week... Last Sunday, our family had dinner early. My mother, who had been tired all day, began to wash the dishes according to the original plan. So I made up my mind to realize this wish today. Just when my mother was still washing her teeth, I had prepared a basin of hot water full of love for her early. I quietly went to her mother and said happily, "Mom, let me wash your feet today and do my filial ty.". Mother felt very confused after listening, said: "daughter, how did you suddenly grow up today and learn to be filial to your parents.". I said: "Mom, this is the result of Teacher Ecation in school. You helped me to do a lot of things before. Today it's my turn to repay you.". After listening to her mother, she said with a smile: "daughter, if you have this filial piety, your mother will be satisfied. You'd better try to do well in your study. That's the best reward for your mother.". I said, "no, I have to wash your feet myself today.". My mother saw that I was very tough and had to comply. I put down the basin, put my hand into the water, measure the temperature of the water to see if it is suitable for washing feet, feel a little hot, I added some cold water. Then help her take off her socks and start to work. From the front of her feet to the back of her feet, from the back of her feet to the soles of her feet, I gently rubbed her feet and found that there was a thick cocoon on the soles of her feet. I knew that she worked too hard for me, and I admired my mother more. After a while, I washed her feet clean, mother smile, "this is the first time I met this kind of happiness.". I immediately replied, "Mom, when I grow up, I will do more for you." In this holiday, I did a lot of housework, which proved that I grew up and learned to do housework. Although I have been exhausted, but can do housework for my mother, my heart is still sweet. O(∩_ ∩) O ha ha ~ come on! Books are the treasure house of knowledge. It makes the accumulation and development of human knowledge and culture, and makes the ignorant become erudite; It is it that constantly enriches my mind and brings infinite joy and hope to my life. When I didn't even know a word, I had an indissoluble bond with the book. When I was very young, like other children, I liked to hear my mother telling stories for me with storybooks. Unlike others, I always listen to every story three or four times before I give up. In the kindergarten, the teacher accidentally found that I could tell stories, so he took out a story book for me to read to the children. Just when the teacher was surprised that I could know so many words, she suddenly found that I had taken the book upside down and was staring at it. It turns out that these stories have been "heard" and "recited" since I was a child. With the increase of word recognition, I can finally read by myself. What a happy thing it is! Every time I was alone in a room, with delicious food, I was intoxicated with excellent works, and lost myself in the pages. That kind of happiness was incomparable to any other feeling at that time&# 57348; I'm intoxicated with literature. From 365 nights to Andersen's fairy tales, so many moving stories and kind-hearted images together shape my simple and optimistic character. From red rock to how steel is tempered, I graally realize the meaning of life and find the end result of my soul in those thousand times of indomitable struggle and countless iron soldiers“ The experience of "San Mao" makes me feel more happy in my life, and the allusion of "head hanging beam, cone stabbing stock" always urges me forward&# 57348; Graally, my interest turned to science books. From the first set of Knowledge Series "one hundred thousand whys" I came into contact with, I don't know how many mysteries I have solved and how many fresh knowledge I have learned. The next reading of "network book", "interesting physics" and so on, I can't help but put down my mind and forget to eat and sleep. It should be said that I would never have been so interested in natural science today if I hadn't read eagerly year after year and day after day&# 57348; Books are my closest friends. They give me knowledge and strength. Today, I roam in the sea of books and learning, tomorrow, I will use knowledge to create life. All this, how can we not say that it is the gift of the book - this is the accident between me and the book. Book, what a simple and ordinary eye! However, it occupies a very high position in my mind. In the long river of my memory, there are always "the story of books" in my mind. I have an indissoluble bond with books. Whenever I hold up a book with a book cover, I can't help thinking of the past... How important books are to me! If I believe that life is the first, then books must be second only to life one - ranking second. I used to cry for the book, sad for the book, that may be my attachment to the book. Whenever I look at a book "retirement", I feel extremely sad, it's like digging half of my flesh. I carefully hide the book in the bookcase, I can't bear to dig out my own flesh? From the first time I saw her, there was an inexplicable feeling in my heart: "she was predestined with me." In the days after that, I would try my best to get close to her and try to understand her. After a short time, I graally found that I had fallen in love with her deeply. Perhaps tired of the bitter and tasteless ABC, or to escape the suffocating x + y = 4, I asked her out again and again, from her fragrant title page, to a strange and fresh world. Don't be "there's gold in the book"
