Regional mining

1.

In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining

the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig

another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful

currency characteristics of bitcoin

1, decentralized

bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom

2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3, exclusive ownership

controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself

4, low transaction cost

bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution

5, no hidden cost

as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay

6, cross platform mining

users can explore the computing power of different hardware on many platforms

2.

Mining means that users download software from personal computers and then run specific algorithms to get corresponding bitcoin after communicating with remote servers

bitcoin is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods

bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware, and the miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by the miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

extended materials:

the founder of bitcoin:

on November 1, 2008, a person who called himself Satoshi Nakamoto posted a research statement on a secret cryptography review group, stating his new idea of e-money - bitcoin came out and the first transaction of bitcoin was completed

bitcoin has got rid of the constraints of third-party organizations with the help of Internet, which Nakamoto calls "regional chain". Users are willing to dedicate the computing power of CPU and run a special software to be a "digger", which will form a network to maintain the "regional chain". In the process, they also generate new money

trading is also extended on this network. The computer running this software can solve the problem of irreversible code, which contains several trading data

the first "miner" to deal with the problem will be rewarded with 50 bitcoin, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes

in 2009, Nakamoto designed a digital currency, namely bitcoin. The booming bitcoin market has gone up and down, and the identity of its founder "Nakamoto" has always been a mystery. Rumors about "the father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura

6. 1、 The background and significance of the research, number and calculation is the most widely used mathematical knowledge in people's daily life, it has always been the basic content of primary school mathematics teaching, and cultivating primary school students' computing ability has always been one of the main goals of primary school mathematics teaching. However, for a long time, the so-called primary school calculation teaching often through mechanical repetition, a large number of topic training, only pay attention to the results of the calculation, and do not pay attention to the calculation process, students do not like the class about calculation teaching, for them, calculation is often endless exercises; Even teachers don't like the teaching of computing. In the teaching of open class, we seldom see the figure of computing teaching. Since the implementation of the new curriculum, the teaching of computing has been greatly improved, but in the teaching of computing, there are some teachers who overemphasize the diversity of computing methods, and the teachers have not played a very good leading role. The classroom is full of "how do you think", "are there any other different algorithms", "how do you like to calculate". In 40 minutes of classroom teaching, you often talk to me. Obviously, we find that although students' thinking is active and the scene is noisy, students' discussion and communication occupy most of the time in the classroom, and there is no necessary practice in the classroom. After that, we find that students' computing ability has declined: many students do not understand the theory, Results the calculation error rate is high, and the calculation speed of many students is greatly reced. It is beneficial for everyone to form a certain computing ability in primary school, and the process of learning numbers and calculation is the process of cultivating and developing students' logical thinking ability. Throughout the primary school mathematics teaching, the calculation teaching occupies a considerable proportion, just look at the textbook directory can be understood; And in the teaching evaluation, the proportion of calculation is also obvious. From a simple point of view, the calculation of 100 points accounts for 40 points, not including the calculation in comprehensive application. In this regard, we put forward the topic of "how to improve the practice and research of primary school students' computing ability". We want to overcome some disadvantages of computing teaching through the practical research of this topic, so that our computing teaching is full of vitality and vitality, which can significantly improve students' computing ability, and let students like to have computing class and do computing problems. 2、 Pedagogy tells us that teachers play a leading role in teaching activities, while students are the main body of learning. China's famous ecator Ye Shengtao also clearly pointed out: "teachers must inspire students' initiative and guide them to explore as much as possible." The common activity process of teachers' teaching and students' learning depends on whether students are willing to learn. Students do not take the initiative to learn, it is not enough to rely on the teacher's hard work. So "teaching" must combine the teachers' serious explanation with the students' active input, in order to receive good teaching effect. 2. Confucius said, "those who know are not as good as those who are good, and those who are good are not as happy as those who are happy." Primary school students are in the stage of image thinking, they are lively, easy to accept lively, infectious, interesting things. Therefore, only when any ecation really stimulates students' interest in learning, can it achieve the maximum benefits and make interest the best teacher for students. 3、 Research status at home and abroad, according to the requirements of China's "mathematics curriculum standards", cultivate students' thinking ability, operation ability, spatial imagination ability, ability to solve practical problems and innovative consciousness. Among them, it is very important to cultivate students' computing ability. In the process of deepening the new curriculum reform, as a front-line mathematics teacher, more and more feel that students' computing ability has declined. Many schools have also carried out some research on this aspect, such as: situational teaching method to improve students' interest; Take care of students' psychology and arrange their homework at different levels; Let students full of confidence in the competition incentive method and so on. Throughout the world, most of the countries have higher requirements on the cultivation of students' computing ability. For example, although the UK does not approve of trivial written calculation, it attaches great importance to the cultivation of mental calculation and estimation ability; In the newly revised curriculum syllabus of Japan, it is clearly proposed to increase the teaching time of Mathematics for "repeated training of calculation". This topic will make full use of the existing experience and theory of computing teaching at home and abroad, on the basis of the existing investigation, research and analysis results at home and abroad, and fully combine with the actual computing ability of students in our school, to further discuss, and strive to build teaching methods and teaching strategies in line with the actual situation of our school ecation. 4、 The main objectives of the research are as follows: 1. General objectives: through the research of this topic, while effectively recing the burden of students, we should strive to improve students' computing ability, cultivate their oral, mental, estimation and written abilities, realize the organic combination of diversification and optimization of algorithms, and promote students to graally like mathematics in a lively and relaxed learning atmosphere, Interested in computing. So as to improve students' academic performance and lay a solid foundation for students' future study. 2. Students' goals: 1. Set up correct learning goals and hard work goals, study consciously and form good calculation habits. ② Students learn to allocate their time independently, organically combine in class and out of class, infiltrate and promote each other. The overall computing power has been improved. ③ Let students improve their computing ability in a relaxed and pleasant learning atmosphere. 3. Teachers' goals: facing the confusion in the new curriculum reform, teachers should be good at discovering, diligent in learning and brave in innovation. Constantly improve their ability in all aspects, have the courage and ability to solve new puzzles. ② We should try our best to find a teaching method and mode that can effectively rece the burden of students, effectively cultivate the ability of calculation and innovation, and promote students to study lively and actively, and graally form their own teaching style and school characteristics. 5、 The content of subject research traditional computing teaching often adopts such a mode: basic training (bedding practice) - Example Teaching (summary rule) - repeated practice (forming skills). In this kind of "pure computing" classroom, the teaching goal is always to remember the calculation rules and form calculation skills, so the classroom of calculation teaching has become a pronoun of monotony, boredom and boredom. In order to deepen the teaching reform, the effective calculation teaching is implemented in the classroom teaching. We divide the research content into four parts: 1. Research on promoting students' good calculation habits. Some students have low computing ability, of course, there are some reasons, such as unclear concepts, no real understanding of computing theory, no proficiency in algorithms and so on, but not forming a good habit of computing is also one of the important reasons. Some of them have bad habit of examining questions, and they often do it after half reading; In some cases, the writing is not standardized, the numbers and operational symbols are scribbled, and the numbers and symbols are copied wrongly; Some people don't have the habit of checking the calculation, so they just finish the calculation. In view of these phenomena, we think that in order to improve students' computing ability, we should first start from cultivating students' good computing habits, so that students can master some computing methods. We will study how to promote students' good calculation habits in classroom teaching, student practice and school activities. 2. How to use classroom teaching to improve computing ability. Dominated by the traditional teaching concept, many teachers adhere to the principle of "practice makes perfect" and implement the "problem sea tactics" in the teaching of computing, which makes more and more students hate and fear computing. Reading the new curriculum standard carefully, it is not difficult to find that the requirement of calculation mentioned "attach importance to the cultivation of students' innovative consciousness and practical ability". This requires us to actively change our teaching concept, and put the teaching goal more in the thinking process of computing itself, and how to carry out the teaching and learning activities of computing, so that students can actively and happily participate in computing, feel the charm of computing, taste the fun of computing, and improve the ability of computing. Therefore, we will study how to use teaching strategies and methods to make students really love and understand computing. 3. To realize the research of algorithm diversification and optimization“ Encouraging algorithm diversification "is an important concept of the new curriculum standard. The essence of algorithm diversification is to let students learn new knowledge from their existing knowledge and experience, and encourage students to explore problem-solving methods through independent thinking, which has received great attention and positive practice from teachers. We will study how to grasp the essence of algorithm diversification in mathematics teaching, deal with the relationship between algorithm diversification and algorithm optimization, and pursue the rationality and flexibility of algorithm. 4. Strengthen the research on the teaching of oral calculation and estimation. Oral arithmetic, also known as mental arithmetic, is a way of directly calculating the number without the help of calculation tools, mainly relying on thinking and memory According to the new curriculum standard, oral arithmetic is not only the basis of written calculation, estimation and simple calculation, but also an important part of calculation ability. It can be seen that the first step to cultivate students' computational ability is to start with the ability of oral calculation. In the aspect of developing students' number sense, mathematics curriculum standard clearly points out that it can estimate the result of operation and explain the rationality of the result. Estimation is one of the effective ways to develop students' number sense, and it is also an important link to ensure the correct calculation, which is very beneficial to improve students' calculation ability. By estimating before calculation, we can estimate the general results and create conditions for the accuracy of calculation; Estimate after calculation can judge whether there are errors in calculation, find out the causes of errors and correct them in time. In the process of students' daily oral and written calculation, both pre calculation and post calculation estimation have certain value. Through research, we can improve the quality of primary school mathematics teaching materials, improve teachers' teaching ability, help teachers consciously and purposefully control and improve their teaching behavior, optimize classroom teaching, and improve the efficiency and quality of mathematics teaching, Change students' learning style, improve students' learning quality, and initially form a set of teaching strategies and methods supported by modern ecation theory. 6、 Research process and methods (1) research process (1) in the early exploration stage (November 2013 - January 2014), strengthen theoretical study, carry out investigation and research, carry out preliminary exploration, formulate implementation plan, carry out subject demonstration and application. Mainly around the new curriculum concept and the theory of mathematical calculation teaching, organize and carry out learning, enrich the knowledge reserve of experimental teachers; Train the research teachers and master the research methods and processes. This paper investigates the current situation of students' computing ability, analyzes the reasons, studies the countermeasures, and formulates the project implementation plan, so as to prepare for the research 2) Research stage (February 2014 to April 2014). Select the appropriate sample of research objects, formulate specific and feasible phased research plan, orderly carry out activities and conct in-depth research. Teachers in the research group teach according to the implementation plan, carry out test evaluation and competition activities, and explore effective strategies to improve students' computing ability. At the same time, we should carry out teaching and research activities, discuss the classroom teaching mode, collect process data, and on this basis, summarize the stage experience around the subject research, and write monographs 3) In the summary stage (April 2014 to July 2014), the research is summarized and the results are displayed

9. 1-75: copper ore (smelting experience, can dig 1-4 times) associated with poor quality stone, malachite
it's easy to dig in the birthplace, plus smelting experience, 50 + mining experience can be easily achieved

75-125: tin ore (smelting experience, can dig 1-4 times) 50 skill requirements, associated with tiger eye stone, shadow stone, rough stone
tin mine is also a very popular mineral. It is recommended by tribes to go to barren land / coniferous forest; The League recommends Chiji mountain

silver ore (smelting experience, can dig 1-4 times) 75 skill requirements, associated with tiger eye stone, rough stone
silver mine is the first rare mine we can encounter. Copper mine generates silver. That is to say, after a certain copper mine is collected, there is a certain chance to refresh silver mine next time. Of course, silver mine is also used as an independent refresh in advanced map. The tribe here recommends barren land / thousand needle stone forest; The League recommends Chiji mountain

125-175: iron ore (can be excavated 1-4 times) 125 skill requirements, accompanied by heavy stones and topaz
there are many places, but none of them is relatively distributed. However, I still suggest to go to the shining plain at the edge of the thousand needle Stone Forest - & gt; Tanalis, there's a lot of data going back and forth on this line

gold mine (smelting experience, 1-4 times of excavation) 155 skill requirements, accompanied by heavy stones and topaz
this is the second kind of rare ore that we can meet, and the last kind of ore with experience in smelting. Iron generates gold. Similarly, after the iron ore is collected, the next refresh will have a certain chance to refresh gold. Of course, the advanced map will refresh, but it is rare

175-245 mitag mine (can be excavated 1-4 times) 175 skill requirements, accompanied by solid stone, turquoise and ruby
two places are recommended for large-scale collection:
1. Barren land, as shown in Figure 1, will brush three secret silver in area a and two secret silver in area B. the refresh of these two places is very fast, and a circle of maps outside can't be finished, so areas a and B will refresh
2. If you think that there are too many people in the barren land, I recommend a small place, the altrank mountains, as shown in Figure 2. In the cave of area a, 2-3 secret silver will be refreshed each time, and in the refresh point outside, 3 mines will be brushed each time. This place has few people, and the map is small, and the refresh is relatively fast, which is suitable for a large number of collection

300-330, mainly to dig the magic iron ore

first of all, dig many magic iron ores distributed on Hellfire Peninsula clockwise

If Hellfire Peninsula is full of miners, go to ZANZA swamp

330-355, mainly for Moxian iron mine and Jiangang iron mine<

going to nagland grassland and digging hard steel ore can not only improve skills, but also sell ore at a good price

at the same time of digging hard steel ore, magic iron ore can also be collected together, even in the later stage, the consumption of magic iron ingot is still considerable

355-375, mainly for Moxian iron mine and Jiangang iron mine

yingyue gorge is the best choice for mining Jiangang mine

if the level is not enough, you can also choose to practice mining skills in the tiroka forest

don't forget to continue to search for magic iron ore while digging hard steel ore in yingyue canyon

if you are in a PvP server, it is quite safe to go to the taroka forest to dig magic iron ore and improve mining skills.
