Bitcoin starts mining

1.

bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it

mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash

and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on

extended data:

mining risk:

1, currency security

the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin

2, system risk

system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners

2. Bitcoin, as a kind of network virtual currency, is very popular. Many people will "dig" bitcoin. Today, let's introce the mining tutorial of bitcoin
Step 1: prepare mining machines and pools
if you want to dig bitcoin, you must prepare professional equipment. At present, there are many professional mining machines on the market, and the pool is also essential. When you choose a pool, you should also compare the output and income gap of each pool, and then choose the most suitable one
Step 2: register and set the mine account
after the mine is ready, register the mine account and set a common email. When setting the mine account, each CPU or GPU needs to set a mine account
Step 3: download the bitcoin miner
after you register and set up your account, you need to download the bitcoin miner. When downloading the miner, be sure to choose the miner that can make your CPU and graphics card play the most function. After downloading, set the server, user name, password, device and so on
Step 4: Mining
after setting up the miner, click the "start mining" button, the miner will enter the state of full speed operation, and the miner will start mining automatically.

Bitcoin is actually a virtual currency. When bitcoin first appeared, if you want to get bitcoin, you have to get bitcoin through mining. Therefore, bitcoin mining appeared. But bitcoin mining is more and more difficult, so it is very difficult to get bitcoin now

so now many people use Haru miner digs Ethereum, Monroe and other virtual coins. Most importantly, BTC can be directly equivalent in the end

4. If you want to dig a mine, you should understand these first, and then decide whether to join the army of miners or not
as a miner, I used graphics card very early and then butterfly machine. At present, I use Avalon's 220 miner and just received a new 180 ant miner. To tell you the truth, mining is not as simple as you think. Here I will list some practical difficulties you need to face in mining. If you find that some of these items can't be solved and overcome for the time being, don't rush to buy a miner, because from the moment you buy, if you can't mine, Then you will face a real loss

first, list the problems to face
1, be able to accept the noise - the noise of the mining machine is very loud, which is equivalent to that you put the air conditioner outside the room
1-1, strong hands-on ability - the noise can be controlled to a certain extent by adding water cooling, but it needs to be done by yourself. The installation process of water cooling is not as simple as the online tutorial. It needs to be extremely careful. The capacitor on the logic board is easy to touch, and it must be successful at one time. Once the refrigerant is added, the machine will have problems again, It would be disastrous to dismantle the water cooling system
1-2, conditional repair of the chip capacitor - in the process of water cooling installation, the capacitor is easy to fall off, these chip capacitors are very difficult to weld
2, you can set up the network - you can't just plug in the Internet cable! Need to understand the routing, know how to change the IP of the router, mining IP is fixed, according to mining IP to do settings
2-1, you can get a fixed IP address - if you are mining in a company, you can't set up a route, so you must have the condition to get a fixed IP, and then set up your own network through this IP
3. The environment of continuous power supply and continuous network - mining is a 24-hour business. Don't take it for granted that a meeting is OK in one day. Many companies will cut off power at midnight. This must be made clear
3-1. In low temperature environment, in addition to 24-hour continuous power supply, there should also be a relatively cold environment. In actual mining, we can clearly feel the importance of temperature for mining<

let's assume two scenarios,
in the company:
if your working environment is very quiet, it is not suitable, even if water cooling is installed. If you are a senior blue collar, in the workshop, do you have the conditions to set up the network and get a fixed IP? If you can't, give up
at home:
can you stand noise? Can tolerate to a certain extent
is it possible to install water cooling? It can be installed conditionally
is it possible to set up a network? There are also conditions to set up the network
is it warm in that room? Yes, but you can open windows on the second bedroom or balcony
is it possible to pull the wire and the wiring board in the balcony? No problem
congratulations, you can buy a miner to dig it up, but if one of them doesn't work, you need to think carefully before making a decision
the above-mentioned points should not be taken as unimportant or major problems. For example, it is necessary to have the conditions to install water cooling, for example, in a lower temperature environment, for example, to have a fixed IP
when the miner starts to operate and makes a rumbling sound, if you are in the company, you have to turn it off awkwardly. If you are at home, you need to figure out how to explain to your family or girlfriend that the noise will exist for 24 hours, and hope they don't mind

if your home is warm, your miner will never be able to achieve the highest computing power it can. You must accept it calmly, don't be depressed, it's useless to find the seller. Unless you open the window to let in the cold air, you will find that you and the miner are so out of place. That's why laomaozi is very fond of mining< Make complaints about mobile phone, br / > and if you work hard to move the mine to the company, you may think that the electricity charge is in the whole province. You can't get the mine to connect. Then you can only move the mine to home or sell it as a second-hand machine...

these words are typed word by word by me. I hope it can help you. You must find out whether you are qualified to do this at present. As for how to dig, it's a very simple thing: buy a miner, register an account on a mining website, Download a multibit to store the bitcoin you get, and link the miner to the network for power on, Set up the network, give it the fixed IP specified on the chassis, use the computer to access the IP, make some simple settings, and then wait for the receipt
what else can I ask you

5. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

warm tips:
1. The above information is for reference only, without any suggestions
2. According to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to the regulation of digital currency in China, investors have the freedom to participate in digital currency transactions at their own risk

6. There are only four steps

1. You need to register a bitcoin wallet, which is equivalent to your bitcoin account
2. Register on the bitcoin mine pool website and connect to your wallet (the mine pool can only remit bitcoin to your wallet, but can't take bitcoin from it)
3. Decide whether to use a mining machine or your own computer. If you decide to use a mining machine, you can buy it. The advantage is that the time to dig bitcoin is much faster than that of a home computer. The disadvantage is that it is too expensive
4. Download the mining software and connect the mine pool through the software to start mining

every step has many choices, because there are many bitcoin wallet registration websites, mine pool websites, many kinds of mining machines, and many mining software
you'd better go to bitcoin.org to choose. There are recommendations on it.

7. First, we need to find a stable bitcoin mine pool which is easy to operate, and then connect to the designated server to mine through the mining client software. Take "BTC guide" website as an example. First open this website and click the user registration on the left. The registration process is relatively simple. You can enter the English user name, password and confirmation password

2 after successful registration, we will see a message like "your account has been successfully registered and logged in!" on the web page, It means that we have successfully registered and logged in

3 we can click the "dashboard" button in the upper left corner to see the whole monitoring status of the account
note: in this monitoring dashboard, we are most concerned about "total earnings", which is the bitcoin earned by our current account. In the future, as long as we open the website and enter the monitoring dashboard, we can see the relevant information of our account
4 next, please click "Settings" in the navigation bar of the page. In the settings page, we can set the e-mail address, bit wallet address, change the password, etc.

5 if we set the e-mail address in the account, if we forget the password or steal it in the future, we can restore the password through the set e-mail. First, enter our common email address in the "email address" column, and then click the "change" button

6. Next, a confirmation email will be displayed on the page to confirm that it has been sent to our previously set email

7. Then we open our email and find the email sent by BTC guide. Click the confirmation link, and then the page will show that our email has been successfully set

8. If we set email in the account setting, we can also set email notification for the behavior of mining miners. Find the "idle warnings" column on the setting page, click the drop-down list, select the time when you want to send the email, and then click the "change" button on the right. When we set 10 minutes later, if a miner stops mining, the system will automatically send a notification email to our email after 10 minutes. After receiving the email, we knew that the miner was on strike

9 in addition, we are more concerned about the "bitcoin wallet", that is, the wallet address. You don't need to set this address first. It's not too late for me to fill in when I really get bitcoin

10 after the account is set up, we need to set "worker". What is a worker? This is the login account name we will use later on the bitcoin mining client. The system will create a miner name for us by default. The miner name is composed of our registered account name, an underline and a number. For example, our registered account is XXX, and the first miner's name is "XXX"_ 1 "
11 if we want to set multiple miner names, enter a number such as" 2 "in the" create worker "column, and then click the" create "button to add a new miner's account name

12 in the worker settings page, we can also set the mining payment mode of the mine account separately. Payment method, i.e. mining payment method. There are two types to choose from, PPS and PPLNs. The difference lies in the mining mode and handling charge. The handling charge of PPS is 7.5%, while that of PPLNs is 3%. The system adopts PPLNs by default. If you want to change it, please click the "change" button under the payment method
13 in addition, we can also choose the difficulty of mining mode. If our computer has multiple graphics card GPUs or some special machines, we can set the miner's account name under the minimum difficulty

Step 2, download the mining client software
1 after we complete the registration setting, Next, please click "support" in the page navigation menu, and we will see the download link of the client< There are two types of mining client software:
bfgminer: command line operation interface, which can be downloaded directly
cgminer: it is also operated in the command line format, but the download steps are too complicated
let's take bfgminer as an example and click download as shown in the figure
2 then it will jump to the download page of mining tools. There are two formats of mining tools, one is 32-bit system, the other is 64 bit system. According to the number of system bits, download the corresponding tool version

3. The client size of mining tool is less than 5m, which is a zip compressed file. When the download is complete, locate and open the file. Click the right mouse button and select the "" option
4 here, I take paste extraction to the desktop as an example
Step 3, mining client software detailed settings
1 after opening the mining directory, double-click to open the "bfgminer" file under the directory
2 next, look at the BFG minier window and enter the address of the mine pool at the URL. The pool address can be seen in the BTC guide's support page, such as stratum. Btcguild com:3333 , press enter key
3, and then enter the miner's name set on BTC guide website after the user name, press enter key
4, and then enter at will in the password, as shown in the figure
5. Finally, you can see that many numbers are changing, It means mining. It is worth noting that the places marked in the figure indicate the speed of the current machine button
6 in addition to the current mining speed on the mining client software, we can also see the specific mining speed of each miner in the "active worker summary" list on the "dashboard" page of BTC guide website
7 If you want to close the mining tool, you can directly x drop it, You can also directly press the Q key to exit. If you want to open more, you can open another mining tool in the BFG miner directory< Step 4: cgminer command line client software
1 if you really want to mine, the official recommends that we use "cgminer", that is, to run it at the command prompt. Click "support" on BTC guide page, then click "cgminer" download link page, select the corresponding system version
2, then jump to cgminer download page and click the link as shown in the figure
3 and then select a version of cgminer. Here I download a Windows version as an example.
4 take the Windows version of cgminer as an example. After the download, unzip it to the computer.
5 open the cgminer directory, find "cgminer"
6. Double click "cgminer" with the mouse, and a command-line window will pop up, prompting us to enter the URL address of the connection server. Enter "stratum. Btcguild com:3333 ”, press the Enter key on the keyboard
7, and then prompt us to enter "user name", that is, the account name of the miner. Press the Enter key on the keyboard

8, and then enter the password. Press the Enter key on the keyboard

9, and wait for a moment, When the client and the service establish a connection, the machine will start mining

10 to quit mining, please press the "Q" key on the keyboard in the window
tools / raw materials
PC with independent graphics card
precautions
if you are using cgminer, the graphics card must support the display of general computing standard, otherwise you will not be able to mine.

8. 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.

9. Diamonds are better to dig, as long as you dig down about 16 squares vertically, you may find diamonds. But the gold ore seems to be distributed irregularly, and there are few diamonds, so we can only rely on luck
