Mining in headmaster's computer room

1.

In short, mining is the use of chips for a random number related calculation, get the answer in exchange for a virtual currency. Virtual currency can be exchanged for the currency of each country through some way. The stronger the computing power, the faster the chip can find this random answer. Theoretically, the more virtual coins can be proced per unit time. Because it's about random numbers, you can only get rewards if you happen to find the answer

In his paper, Nakamoto stated:

"in the absence of central authority, it not only encourages miners to support bitcoin network, but also enables bitcoin's currency circulation system to have the initial source of money injection."

Nakamoto compares the generation of bitcoin by consuming CPU power and time to the consumption of resources by gold mines to inject gold into the economy. Bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through peer-to-peer network, digital signature and interactive proof system

each network node concts broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express their confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain

Nakamoto himself designed the first version of bitcoin mining program, which was later developed into the first generation of widely used mining software bitcoin, which was popular from 2009 to mid-2010

each bitcoin node will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the SHA-256 hash value of the previous data block. The mining node tries again and again until it finds the random adjustment number so that the hash value is lower than a specific target

extended data

at the earliest, bitcoin miners were mining through Intel or AMD CPU procts. But because mining is a computing intensive application, and with the continuous improvement of mining number and equipment performance, the difficulty graally increases, now using CPU mining has no profit or even loss

as of 2012, since the first quarter of 2013, miners graally began to use GPU or FPGA and other mining equipment [5]. At the same time, a large number of ASIC devices were launched in mid 2013

since July 2013, the computing power of the whole network has shown a straight-line rise e to the large number of ASIC equipment put into operation. Based on the average computing power in July 2013, all CPU mining equipment has been unable to generate positive revenue, and FPGA equipment is close to no revenue

according to the estimation of average computing power in September 2013, the existing small ASIC mining equipment developed for indivials will also be close to no positive revenue in the next 1-2 months. A large amount of computing power is monopolized by cluster ASIC mining equipment with 5 th ash / s or more. Because of no profit, indivial mining is almost squeezed out of mining groups. Some bitcoin miners have raised funds to build machine rooms and install a large number of mining equipment in places where low-cost electricity can be obtained

in order to save the cost of mining, some bitcoin miners make mining programs into malicious programs to infect other people's computers on the network to mine for themselves

2. In fact, not much harm, mainly equipment radiation, eat more anti radiation dishes. Of course, the radiation value should also be within the safe range, don't worry......

3. Should suggest the school. Internet speed up. A mining card. Public organs of the equipment is like this. Really bad
you should thank the mining man and point out the serious shortcomings of the school computer room

5. infeasible. Mining needs a lot of electricity. The computer room does not support it.

6. However, thousands of computers running at the same time how spectacular electricity charges!!! How do you make the assignment when school begins
other people's mines rely on the surplus electricity of small hydropower stations. I feel that they are making some coolie money. If the mining profits are too high, why should they cut the electricity bill... So when you're ready for the electricity bill of 1000 computers for two months, start mining boldly!

in the middle and late 1990s, with the development of society, people are eager to enjoy high-quality ecation nearby. The good school running foundation and teachers of the school have aroused widespread social concern. The provincial and municipal people's congresses visited and inspected many times, and suggested that the government set up key high schools here. After the third full church, with the spirit of being highly responsible for the party and the responsibility of revitalizing the school and benefiting the people, our school has grasped the good opportunity of popularizing high school ecation by carefully investigating, objectively analyzing and making scientific decisions. With the reform and innovation action and the strong support of the leadership of the municipal government and the Municipal Ecation Bureau, our school cooperated with the University of science and technology in running the school in 2000, Taiyuan No.29 middle school has been established as "Experimental Middle School of Taiyuan University of technology" with the characteristics of science and engineering. It is the first time to reform the school running system of ordinary high schools in our city. It has found a new way to make full use of the advantages of university resources and speed up the development of ordinary high schools
a new school running goal. With the support of the Municipal Bureau of ecation and the University of science and technology, the school will be built into a complete middle school with the characteristics of "science and Engineering", which will graally have solid basic courses, extensive channels of knowledge innovation, and rich content of science ecation, It focuses on the cultivation of high school graates to meet the needs of science and engineering universities, and the cultivation of junior high school students' personality and specialty in "science and Engineering" knowledge
unique curriculum system. On the basis of making full use of the information resources and expert intelligence resources of the University of science and technology, opening the compulsory courses, elective courses and activity courses stipulated by the state in the senior high school stage and the compulsory ecation courses in the junior high school stage, the development courses such as information technology, oral English and popular science ecation are highlighted
the current leading group advocates the school running concept of "determination, diligence, harmony and development". It takes "civilized and enterprising, realistic and innovative" as the school spirit, takes "rigorous and erudite, good at teaching and loving students" as the teaching style, takes "diligent and civilized" as the learning style, takes "respecting teachers and loving students, uniting with civilization, pioneering and enterprising, and all-round development" as the school motto, and "relying on the advantages of university resources, Accelerate the development of basic ecation, provide qualified freshmen for higher schools, cultivate talents needed at all levels for national development and construction, and create first-class middle schools to benefit the masses. We should find a new way to speed up the development of ordinary high schools by fully relying on the advantages of university resources. Under the new management system, the University adheres to the road of developing the university through scientific research, makes full use of the information resources of the University of science and technology, the intellectual resources of experts, the cutting-edge ecational technology and the resources of foreign teachers, goes deep into school-based teaching and research, and solidly carries out scientific research projects. It has successively won the titles of "Shanxi civilized school", "Taiyuan civilized unit", "Taiyuan moral ecation demonstration school", "Model school of moral ecation", "model school of comprehensive management", junior high school mathematics, chemistry, computer and other discipline competitions have been at the top of Taiyuan ordinary middle school group for many years, "comprehensive award of junior high school ecation and teaching quality", "advanced collective of compulsory ecation curriculum reform", "second prize of classroom teaching group exhibition competition" and other municipal honorary titles, The senior high school has won the "excellent school award of Taiyuan ordinary high school teaching quality", "ordinary high school teaching characteristic Award", "high school graation examination Award", "Taiyuan advanced teaching and Research Office", "advanced party organization", "advanced Party branch", "advanced collective of veteran cadre work", "excellent ideological and political work unit", "advanced collective of three ecations" for several consecutive years, The administrative party branch was awarded "Taiyuan Party member pioneer post", "Taiyuan advanced League Organization", "advanced trade union", "red flag Youth League Committee", "young eagle brigade", "advanced unit of joint military and civil construction and ecation", "advanced unit of ecation system safety work", "advanced unit of 100 day traffic safety centralized control", "advanced collective of popularizing experimental teaching", "2003-2005 advanced unit of three ecation work", "advanced collective of compulsory ecation curriculum reform", "excellent award of teaching management and teaching quality".

10. At night, I had a dream. I dreamt that I became the headmaster of No.1 middle school. My school has beautiful scenery and charming scenery. Every student is energetic and energetic. As for teachers, every teacher is conscientious. In fact, what makes me most proud is the set of audio-visual facilities in my school. It helps me a lot and saves me a lot. But when I was happy, someone suddenly told me that all the audio-visual facilities were paralyzed and could not be used. It just woke me up. Ah! It turned out to be a dream

as the saying goes, "every day has a thought, and every night has a dream.". In fact, I sometimes wonder what my school would look like if I were the principal of No.1 middle school? May be like my dream is so charming, will attract everyone to our school, make everyone nostalgia! But I'm not a headmaster, but I have many golden ideas! I can provide my golden ideas for the construction of No.1 middle school
as far as I am concerned, I think if we want to make the construction of No.1 middle school better, we should first improve the overall quality and cultivation of teachers; Our school can send some excellent teachers to some prestigious, advanced schools with high enrollment rate to conct research and observation classes. Communicate with teachers of other schools, learn their experience and teaching methods, learn their advanced ecation concepts and teaching management, so as to strengthen the overall team of teachers and improve the overall quality of teachers. But at the same time, the treatment of teachers should also be improved, so that teachers have no worries, light to go to battle. Devote oneself to teaching work wholeheartedly, make their level can develop incisively and vividly! Secondly, we should strengthen our school's audio-visual facilities! Install a closed circuit TV in each class to strengthen teaching management and improve teaching quality; Strengthen the teaching monitoring, monitor the amount of homework, monitor the opening situation, monitor the teaching time, monitor the teaching effect, school leaders can carry out surprise lectures, can hold student seminars, understand the teaching situation. In addition, I think the school should set up a literature society, open a sub website in the school network, give students a stage to show frequently, and form a school-based curriculum. Schools should also give students more stage to show their talents and cultivate their hobbies and interests! In order to hold activities in the city or district will get a good result! Finally, I suggest that the school can increase some recreational facilities, so that students can relax and ease in the daily tense study
this is my golden idea, I hope my school can be more perfect in the future life, no matter in the quality of teachers, teaching facilities, teaching environment or teaching philosophy can become the top! However, I think the most necessary is the audio-visual facilities, with which students can certainly improve the atmosphere of class. It can also rece the burden of teachers
I think in the future, the construction of No.1 middle school will graally become high-tech and high-level! And the quality of teaching will be higher and higher; I believe that in the near future one will become a prestigious, famous and advanced teaching unit!
