Bitcoin public chain mining mode

1. Yes, now you can buy a miner to dig bitcoin
but what I want to emphasize is that bitcoin mining is now a very professional instry. Although ordinary people can dig, the cost is much higher than that of professional mining, so it's better to buy money directly.

2.

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

3. 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

4. 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

5. Mining is a process to increase the supply of bitcoin money, while protecting the security of the bitcoin system and preventing fraulent transactions. Miners provide computing power for the bitcoin network in exchange for the opportunity to obtain bitcoin rewards
bitcoin system is composed of users (users control the wallet through the key), transactions (transactions will be broadcast to the whole bitcoin network) and miners (a blockchain is generated by competitive computing to reach a consensus at each node, and the blockchain is a distributed public authoritative account book, including all transactions in the bitcoin network)
mining is a process of increasing bitcoin money supply. Mining also protects the security of the bitcoin system, prevents fraulent transactions, and avoids "double payment", which means spending the same bitcoin multiple times. Miners offer algorithms for bitcoin networks in exchange for the opportunity to get bitcoin rewards. The miners verify each new transaction and record it in the general ledger. Every 10 minutes, a new block will be "mined", and each block contains all the transactions from the generation of the previous block to the present, which are added to the blockchain in turn. We call the transactions included in the block and added to the blockchain "confirmed" transactions. After the transaction is "confirmed", the new owner can spend the bitcoin he gets in the transaction
there are two types of rewards for miners in the process of Mining: the new currency reward for creating a new block, and the transaction fee for the transaction contained in the block. In order to get these rewards, miners compete to complete a mathematical problem based on encrypted hash algorithm, that is, to use bitcoin mining machine to calculate the hash algorithm. This requires strong computing power, how much the calculation process is, and whether the calculation results are good or bad. As the proof of miners' calculation workload, it is called "workload proof". The competition mechanism of the algorithm and the mechanism that the winner has the right to record transactions on the blockchain ensure the security of bitcoin
miners also get transaction fees. Each transaction may contain a transaction fee, which is the difference between the input and output of each transaction. A miner who successfully "digs" a new block in the process of mining can get all the transaction "tips" contained in the block. With the decrease of mining reward and the increase of the number of transactions in each block, the proportion of transaction fee in miners' income will graally increase. After 2140, all miners' earnings will be made up of transaction fees
mining is a process of decentralizing settlement, in which each settlement verifies and settles the processed transaction. Mining protects the security of bitcoin system, and achieves the consensus of the whole bitcoin network without a central organization. The invention of mining makes bitcoin very special. This decentralized security mechanism is the basis of point-to-point e-money. The reward and transaction fee for casting new coins are a kind of incentive mechanism, which can regulate miners' behavior and network security, and at the same time complete the currency issuance of bitcoin.

6. 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.

Bitcoin is an electronic currency proced by open source P2P software. Digital currency is a kind of network virtual currency. Bitcoin is also paraphrased as "bitcoin.". Short for: BTC

bitcoin does not rely on a specific monetary institution. It is generated through a large number of calculations of a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
bitcoin is very similar to cash
the advantages of bitcoin are: no freezing, no tracking, no taxes, and extremely low transaction costs. Compared with people who speculate in currency, it is wealth, and people outside the currency circle may think it is a fraud
bitcoin is a relatively mainstream digital currency, which can be properly invested. There are risks in the transaction. You can invest cautiously. You can search the fire coin, coin security, OK, dobby trading platforms on the Internet, which can trade bitcoin. These are relatively large trading platforms. Invest in mainstream digital currency, do not invest in counterfeit currency or air currency< br />
