1. At present,
bitcoin is the only reliable
virtual currency. Bitcoin is a kind of virtual currency generated by the corresponding algorithm, which needs to use a large number of
mining machines, that is, servers for mining. At present, only the virtual currency issued by the central bank is legal in our country, and the others are illegal
I hope I can help you. Thank you for your adoption.
2. Mining is the use of bitcoin mining machine, which is used to earn bitcoin
one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, can surpass the single graphics card of most users
and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining
< H2 > extended data:
bitcoin mining process:
1. To find the ore pool
to start mining, there must be a ore pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm
2. Download bitcoin miner (software)
in fact, there are many kinds of this miner, you can go to the official website to download
3. Setting mining software is a green software. After installation, we can set the language first to facilitate further setting. Next, you need to set the server, user name, password, equipment and so on. Generally, the server chooses a better network from BTC guide series, and the user name and password are set by ourselves before
4, bitcoin mining start
when we confirm that all settings are correct, click the "start mining" button to start bitcoin mining, and then the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, you can monitor the state through gpu-z or graphics card driver
3. The bitcoin mining machine downloads the mining software and then runs a specific algorithm to get the corresponding bitcoin after communicating with the remote server, so as to obtain the bitcoin
any computer can become a mining machine, but the benefit will be relatively low, and it may not be able to dig a bitcoin in ten years. Many companies have developed professional bitcoin mining machines, which are equipped with special mining chips, and their computing speed is tens or hundreds of times higher than that of ordinary computers
bitcoin miners can neither increase their rewards by cheating, nor deal with the fraulent transactions that destroy the bitcoin network, because all bitcoin nodes will reject the blocks containing invalid data that violate the bitcoin protocol rules. Therefore, even if not all bitcoin miners can be trusted, the bitcoin network is still secure
extended data:
mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network
this process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary
anyone can run software on specialized hardware and become a bitcoin miner. Mining software monitors transaction broadcast through P2P network and performs appropriate tasks to process and confirm these transactions. Bitcoin miners can earn transaction fees paid by users to speed up transaction processing and additional bitcoin issued according to fixed formula
4. Hello! Not good to add, first of all, the network speed is not fast, the above reply hope to help you!
5. The most fundamental way of children's learning should be activity, which is the bridge between subject and object and the direct source of cognitive development. According to the psychological characteristics, letting students explore knowledge independently in the coordination of hands, mouth and brain can develop students' cognitive structure. This requires us to change the classroom teaching mode in teaching, implement open teaching, and let students study independently. I always encourage students to think freely, rationally, boldly and even fantastically in class. For example, when learning "the destruction of the Old Summer Palace", the multimedia courseware was used to create the situation, and the fragments of the movie "burning the Old Summer Palace" were shown to the students. Then they thought of gunpowder. They proposed: China was the first to invent gunpowder, why not make artillery and fireguns to deal with the British and French allied forces? In this way, the students' thinking suddenly goes beyond the books. Second, let the students "see" as much as possible, and cultivate the students' discovery ability. "See" is to let the students watch, observe, give enough time to observe, obtain "discovery" through "see", and actively learn knowledge on this basis. For example, when learning the scenery of Yuanmingyuan, Cai is used to show the scenery pictures of Yuanmingyuan. The students can observe and appreciate them heartily, and then according to their own observation and discovery, give the pictures a name with the same beauty as the pictures - title. Then compare the original name of the picture with the name of your own question to see who is good and why. For example, according to the architectural characteristics of "flower array", it is like a blooming lotus and is named "stone flower jade Pavilion". In this way, students explore and creatively learn knowledge on the basis of full "seeing". Third, let the students "draw" as much as possible to cultivate their thinking ability. Students can draw and describe the information they have obtained from different perspectives and levels of thinking by seeing, experiencing and imagining with their own eyes, and then express it with language, so that the students can better move their hands and brains in class, and overcome the problem of using only ears to listen, listening and thinking in class It is not enough to operate without small hands. In the class of painting style of the first grade, the word "painting" was fully reflected in the design. Both the teacher and the students expressed certain thinking results in the way of painting. The teacher used "simple strokes" to write on the blackboard the things in the wind mentioned in the book. In the class, the students were also designed to "draw" the "wind" on a beautiful landscape painting to see whose way they thought more, And tell us why we draw the wind in this way. In this way, the consciousness and interest of students' active exploration are aroused, and the ability of students' brain and hands-on is cultivated. In the process of exploring how to draw, students will understand that the wind can not be drawn directly, only through other things in the wind to express this point, which is much better than the effect of the teacher. Fourth, let the students "speak" as much as possible, exercise their eloquence, and express the rationality of their thinking through language, so that they can understand how the students think and how to achieve the rationality of their thinking. The teacher creates a free space for students to speak freely, and truly achieves a harmonious and democratic classroom teaching atmosphere, giving students a blue sky of independent exploration. For example, the students' oral expression ability, thinking ability and the ability to organize language quickly can be trained by means of "naming, speaking on stage, group speaking, question and answer type communication" and "adding, summarizing, modifying, correcting and synthesizing". Fifthly, let the students "do" as much as possible to cultivate their practical ability. The process of doing it by themselves actually includes the process of thinking and exploration. Here we should design and provide the time and necessary material conditions for the students to do it. For example, when reviewing idioms at the end of the term, we should change the way that the teacher found out the idioms in a book and let the students , read and remember them. Instead, we should trust the students and let the students read the text by themselves. We should also ask the students to compare and compare. Who can find all the idioms in a book. In this way, students fully reflect their autonomy and enthusiasm in the process of finding out for themselves. Sixthly, let the students accept the knowledge critically and creatively, show the thinking process, create a relaxed environment, require the students to adhere to the truth, follow the objective laws of things, dare to doubt the predecessors, not only books, not only on. For example, when learning the lesson "Zhan Tianyou", the students admired Zhan Tianyou, and at the same time, they also talked about their own design and ideas for his "herringbone railway design", "middle shaft sinking method", "relative shaft sinking method", and carried out reasonable imagination and scientific thinking. For another example, when studying snakes and crops, the students boldly said, "the reason why the crops can't get a good harvest is not only because they were drowned by the flood, but also because the sea water is salty, which destroys the soil and makes the soil unsuitable for the growth of crops. But after a few years, the rain from the sky diluted the soil that had been destroyed by salt water before, so the crops were harvested again, not only because of snakes. Students use their own knowledge and experience for reasonable analysis, dare to doubt, dare to accept knowledge creatively, and fully show the students' reasonable thinking process. 7. To teach students the "method" and "place" of "fishing", it is often said that "teaching people how to fish is beneficial for life". In this knowledge-based economy era with knowledge explosion, today's knowledge will not be enough tomorrow. We should not only teach students the learning method of "how to fish", but also tell students the place of "fishing", Tell students where to find, where to learn, where to find what they need, how to collect some information and where to get information, that is, tell students the ways and channels to collect information and obtain information. For example, through newspaper clippings, book excerpts, TV recordings, radio recordings, CDs, disks, online downloads, field surveys, their own life experience, special interviews and so on. How to sort out and deal with the collected materials to make them useful to you? If you know "there will be rain tomorrow" from "TV", how will you deal with this information? You'll take your umbrella tomorrow. What do you think if you read in the newspaper that a middle school student committed suicide by jumping off a building because of his poor exam results? What kind of inspiration will your psychology proce? If you are also a person with poor enrance and can't stand setbacks, how will you deal with this situation? Should I adjust my mind and treat the exam correctly? In this way, it can help students master the ways of collecting information, acquiring knowledge and processing information. As long as we change the concept of ecation, leave time, space and opportunity for students, let them think, see, speak, draw, do and doubt boldly, and teach them not only learning methods but also ways to acquire knowledge, we can cultivate students' ability and consciousness of independent inquiry.
6. Hello: for you who are puzzled by this problem, I use a metaphor, you can suddenly see that the skinny camel is bigger than the horse. Mining engineering involves not only coal mines, but also other mines, such as iron ore, gold mine and so on. Don't beat yourself to death just because of the depression of an instry. Mining is slowly recovering now, and you don't have to go to mines to learn mining related knowledge. For example, it's OK to major in underground engineering.
7. There are many kinds of mineral resources in Africa with large reserves. The reserves and output of diamond, gold, chromite and phosphate are among the top in the world; Gold; Chromite; Phosphate
8. Generally speaking, you decide according to the monster level and task level of the current map. The higher the task level is, the higher the mining skills are needed. Therefore, the early stage of mining is in the map of the first task you graate from your birthplace. Then, mine according to this
9. Obviously, there are a lot of mining holes, but the server generally won't leave a hole for you (if you go in late), so you can try the fishbone mining method from the 13th floor to the 11th floor, and the ore yield is not low. Before mining, it's nothing more than torches and pickaxes. I'm used to taking a group of iron ingots and a group of wooden boards. It depends on my personal preference...
