Let me introduce to you what
Bitcoin is. Bitcoin is a kind of cryptocurrency based on decentralization, adopting peer-to-peer network and consensus initiative, open source code, and blockchain as the underlying technology. Bitcoin is developed by Satoshi Nakamoto. The paper was published on October 31, 2008, and the genesis block was born on January 3, 2009. In some countries, central banks, and government agencies, Bitcoin is regarded as a virtual commodity instead of currency. Anyone can participate in bitcoin activities and can be issued through computer operations called mining.
By the way, do you know how much Bitcoin is worth?
As of January 13, 2021, 1 bitcoin is approximately equal to 210,000 soft sister coins!
Heart it 
harm me anyway, is the heart of a group.
210,000 Ah is too fragrant. When you
mention Bitcoin, you have to talk about the
blockchain. Let me briefly explain the meaning of the blockchain: Blockchain (English: blockchain or blockchain) is connected by cryptography. Concatenated text records (also called blocks) of protected content.
Each block contains the encrypted hash of the previous block, the corresponding time stamp, and transaction data (usually represented by the hash value calculated by the Merkle tree algorithm). This design makes the block content difficult The characteristics of tampering. The distributed ledger connected by blockchain technology allows two parties to effectively record the transaction and can check the transaction permanently.
At present, the biggest application of blockchain technology is digital currency, such as the invention of Bitcoin. Because the essence of payment is "adding the amount reduced in account A to account B". If people have a public account book that records all the transactions of all accounts so far, then for any account, people can calculate the amount of money it currently has. The blockchain is precisely the public account book used to achieve this purpose, which saves all transaction records. In the Bitcoin system, a Bitcoin address is equivalent to an account, and the amount of Bitcoin is equivalent to an amount.
According to the basic Bitcoin algorithm, Bitcoin generates 1 block every 10 minutes, and each block has N Bitcoin as a reward (the number of N is explained below). This block contains all the blocks in the last 10 minutes. Bitcoin transaction information. The process of making Bitcoin is called "mining". In this process, the computer packs the recently received bill in the newly produced block. This packaging process is the production process, and there is only a very rare chance. Was made successfully. (You can understand it as putting the newly received bills together, forming them once and not modifying them. If the manufacturing fails, you will have to do it again.) Once the manufacturing is successful, you will broadcast this block, which means that you have obtained N bitcoins in this block are rewarded.
So what is N? According to the Bitcoin algorithm, in the first 4 years from the date of Bitcoin’s release, N = basic reward (50 Bitcoins) + transaction reward (the transaction fee consumed by the entire Bitcoin network in the past 10 minutes, as mentioned above , Each bitcoin transaction will consume 0.001 bitcoin as a reward to the miner), every 4 years, the basic reward of N will be reduced by half, that is, the first 4 years will be 50, and the 5-8 years will be 25 , The 9th-12th year is 12.5, and so on. As Bitcoin becomes more popular and transactions become more frequent, N's transaction rewards will gradually increase.
Since May 2013, Bitcoin has officially entered its fifth year. Therefore, until May 2017, the reward N of each block is 25 + transaction reward. According to the current Bitcoin price, the reward of each block It is approximately equal to 210,000 yuan.
Mining steps
(1) Download the official Bitcoin client
(2) After installing the client, start the client. Generally, the network data will start to synchronize within 3 minutes after the client is started. Because the Bitcoin data is very large, this may require several Hours (determined according to internet speed and computer performance). The picture shows the client synchronizing network data:
Please make sure that your C drive has more than 10GB of free space. If the C drive space is not enough, you need to set the data to the D drive or E drive
(3) If your client shows English, and you are not familiar with English Good at it, you can set it to Chinese
(4) The client's synchronization of network data will not affect our mining, we first get our account address, click on the client's "receiving address" button, then you will see a string A very long address, similar to 19G5E9SY5WKdMJEJd71Zs35G8V6x2o3qpG, is your Bitcoin account. The Bitcoin account address is automatically generated and the only address in the world.
(5) Your account is now 0.00 BTC, which means you don’t have Bitcoin, but you can start mining now. Download a simple and easy-to-use mining software CGMiner (CGMiner can mine Bitcoin and most currencies , But not all currencies can be mined with CGMiner)
(6) You need to confirm your graphics card model. If it is an nvidia graphics card, then you can directly mine. Please skip this step. If it is an ATI graphics card, in addition to CGMiner, you also need to install an AMD SDK package. Click here to download the AMD SDK installation package
(7) CGMiner is an English interface, but this does not affect a rookie to use it, please unzip the downloaded CGMiner to your computer Anywhere, and then enter the CGMiner folder.
(8) In the cgminer folder, create a new text file (TXT) and write the content code as:
cgminer -o http://pool.btc38.com:9332 -u XXXXXX -p btc38 modify
the above XXXXXX to The account address of your BTC wallet (obtain your address according to Article 4 of this tutorial), fill it out as shown in the figure:
The editor has already configured the mining pool and port for you in the above code (the mining pool is a completely free mining pool provided by BitTimes). If you want to use other mining pools and ports in the future, please modify the mining pool yourself. URL and port.
(9) Change the .txt suffix of the TXT text file you just created to .bat suffix (if you compare dishes, the suffix name will not be displayed after the text file and the file name suffix will not be changed. After modification, this file is shown in the figure Shown:
(10) Then double-click to run the run.bat file above to start mining. The income you generate when you mine, for example, if you get 0.001 bitcoins, it will be stored in the BTC address you filled in (because the difficulty of BTC mining at this stage is very high, you may have to wait a whole day to get BTC income, there may be some cards on the computer screen when mining, because most of the graphics card resources are occupied). The picture shows the Bitcoin dug by the editor himself during the test:
(11) You may also want to know how to understand the mining interface. The following figure mainly identifies your speed and status:
Note: In fact, the number of Bitcoin mining users is very large, and the Bitcoin output every 10 minutes is very limited, so the difficulty of mining is already very, very large. If you have a powerful graphics card, it will There are certain benefits. If your graphics card is not good, then you may need to spend N hours to get a little bit of Bitcoin.
Bitcoin mining pool.
As mentioned above, the number of users of Bitcoin mining is very large, and the Bitcoin output every 10 minutes is very limited, forming a situation where tens of millions of people grab 1 block, so if you Mining with a personal computer alone may not be able to grab a block for a whole year. In this case, people have come up with a method of team mining. The so-called team mining is what we are now The mining pool to be told.
The mining pool is a server designed through a specific algorithm. All users connected to the mining pool server will team up for mining. Although the performance of personal computers is small, thousands of people will team up for mining. The overall performance It will become very powerful. In this case, the mining success rate will be greatly improved. Once the team in the mining pool successfully creates a block, then all the people in the team will pay dividends based on each person's computer performance. For example: 1000 people are digging in the same mining pool. After digging a block, the reward of N bitcoins generated by this block will be distributed according to the computer performance of these 1000 people. If your computer's performance is strong, it may be assigned to 1/100, and if its performance is lagging, it may be assigned to 1/10000.
In this case, the developers of the mining pool generally charge a fee of 1% to 3% for each user as a handling fee, but because this method allows everyone to obtain bitcoins more stably, almost everyone will choose the mining pool to mine Mining, rather than separate mining
. The free mining pool provided by the Bit Times mentioned in the above mining tutorial adopts the P2Pool technology architecture and does not charge any fees to users. It is one of the mainstream mining pools, and there is also BTC Guild Mining pools such as deepbit and deepbit are also very popular. Although the design of each mining pool is different, the method of use is basically the same and simple, so this tutorial will not go into further details, you can explore it yourself.
Bitcoin mining strategy
First of all, let's ignore the basic principles of Bitcoin. We understand that as long as the computer performance is better, the efficiency of mining will be higher. Due to Bitcoin's algorithm, in fact, the better the performance of the graphics card core, the higher the mining efficiency. The following tutorial will give you a comparison of the mining efficiency of mainstream graphics cards after testing:
ATI series graphics cards
HD 6570 | rate 78.5 MHash/S
HD 6670 | rate 96.9 MHash/S
HD 6750 | rate 156.3 MHash/S
HD 6770 | rate 182.3 MHash/S
HD 6790 | rate 182.5 MHash/S
HD 5870 | rate 343.2 MHash/S
HD 6950 | Speed 299.3 MHash/S
HD 6970 | Speed 355.1 MHash/S
HD 6990 | Speed 714.8 MHash/S
HD 7950 | Speed 453.7 MHash/S
HD 7970 | Speed 566.2 MHash/S
HD 7990 | Speed 1073.5 MHash/S
NVIDIA series graphics card
GTX 285 | Rate 56.1 MHash/S
GTX 460 | Rate 71.1 MHash/S
GTX 570 | Rate 124.2 MHash/S
GTX TITAN | Rate 302.4 MHash/S
We see that in terms of the efficiency of mining, the N series graphics cards of the same price are completely It is not as good as A series graphics cards, which is determined by the design architecture of the graphics cards, so this tutorial will not test more N series graphics cards.
The above rate indicates the difference in the mining efficiency of each graphics card, so how much return can these efficiency be obtained? This is not an absolute value. Under the current mining difficulty (the more people who mine, the greater the difficulty will naturally be), for every 100 MHash/S rate, about 0.002 bitcoins can be obtained in 24 hours in return, according to the bitcoin at the beginning of June 2013 Market conversion, which is 1.6 yuan. Obviously, this 1.6 yuan is basically not enough for electricity bills. Therefore, computers with poor graphics cards are not suitable for mining BTC. Assuming your graphics card performance can reach 300MHash/S, then the daily income can reach almost 5 yuan.
Speaking of this, everyone cannot help asking, is there a better mining method?
The answer is: yes.
Professional mining 1: Graphics card container mining machine
. Some professional mining players use their own modified computers to install two or even six graphics cards on the same computer, so they can obtain several times the mining of others. Efficiency, as long as the power supply and heat dissipation are guaranteed, this is undoubtedly a better approach. If you want to install multiple graphics cards for mining, it is recommended to go to the computer sales store first to consult the detailed installation method and the matching power supply and motherboard. 6 The graphics card installation is shown in the figure:
Occupational mining 2:
Some laboratories dedicated to industrial mining machines , through technical research, have invented some mining chips specifically used to manufacture Bitcoin, which have the characteristics of high efficiency and low power, and are undoubtedly used for mining. But they all have the same shortcomings: the quality is not stable enough, nothing can be done except mining, and the price is expensive.
The mainstream mining machines now include: ant mining machine, butterfly mining machine, honeycomb mining machine, panda mining machine and so on. These miners generally use USB to connect to the computer, instead of graphics cards for mining. The power of the mining machine is usually only in the range of 30~200W, but the mining rate can reach 5000 or even 50000MHash/S, which has become the favorite and first choice of absentees. If you want to buy a mining machine to mine Bitcoin, you can go to a treasure Someone waited for a website to search. The picture shows two brands of mining machines: (Mining machine prices are not cheap)
In the
previous tutorial of Bitcoin mining software , we talked about the Bitcoin mining software CGMiner. In fact, CGMiner is only one of many mainstream mining software. Because of its simple interface, it is more suitable for novices. However, some miners prefer to use mining software such as GuiMiner and CPUMiner. These tools have their own advantages and disadvantages, but they are basically the same. You can choose your favorite mining software through your own attempts. Commonly used mining software includes GuiMiner, CPUMiner, etc. There are many others you can try.
You don't need to know programming skills to mine Bitcoin, but if you understand the underlying principles and can program, you will know what many people don't know. For example, java language and python language are very helpful.
