What is n 5 private mine pool

1. Xiaomi mobile phone can't dig bitcoin<
mining steps:
(1) Download bitcoin official client, click here to download bitcoin official client

(2) after installing the client, start the client, and the client will start to synchronize network data within 3 minutes after startup. Because bitcoin data is huge, it may take several hours (depending on network speed and computer performance). The picture shows the client synchronizing network data:

please make sure that your C disk has more than 10GB of free space. If the C disk is not enough, you need to set the data to D disk or e disk. Check the method of putting bitcoin packets to D disk

(3) if your client displays English and you are not good at English, You can set it to Chinese. Click here to see how to set the bitcoin client to Chinese.

(4) the client's synchronization of network data will not affect our mining. First, we get our account address and click the "collection address" button of the client. At this time, you will see a very long list of addresses, similar to your bitcoin account, The bitcoin account address is automatically generated and unique in the world

(5) your account is now 0.00 BTC, which means you don't have bitcoin yet, but you can start mining now. Download an easy-to-use mining software cgminer. Click here to download the bitcoin mining software cgminer (cgminer can dig bitcoin and most of the coins, But not all currency mining can use cgminer)

(6) you need to confirm your graphics card model, if it is NVIDIA graphics card, then you can directly mine, please skip this step. If it is an ATI graphics card, you need to install an AMD SDK package in addition to cgminer. Click here to download the AMD SDK installation package

(7) cgminer is an English interface, but it does not affect a rookie to use it. Please unzip the downloaded cgminer to anywhere on your computer, 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
change the above XXXXXX to the account address of your BTC wallet (get your address according to section 4 of this tutorial), After filling in, it is shown in the figure:

Xiaobian has configured the mine pool and port for you in the above code (the mine pool is a completely free mine pool provided by bitage). If you want to use other mine pools and ports in the future, please modify the mine pool URL and port by yourself

(9) change the. TXT suffix of the newly created TXT text file to. Bat suffix (if you compare dishes, the suffix will not be displayed at the back of the text file and the file name suffix will not be changed, please click here). After modification, the file is as shown in the figure:

(10) then double-click the run.bat file above to start mining. For example, if you get 0.001 bitcoin, it will be stored in the BTC address you fill in. (because BTC mining is very difficult at this stage, you may have to wait for a whole day to get BTC revenue. When mining, there may be some cards on the computer screen, because most of the resources of the graphics card are occupied.). (11) you may also want to know how to understand the mining interface. The figure below mainly indicates your speed and status:

note: in fact, the number of users of bitcoin mining is very large, and the output of bitcoin every 10 minutes is very limited, so mining is very difficult, If you have a powerful graphics card, there will be certain benefits. If your graphics card is not good, it may take you n hours to get a little bit of bitcoin. This tutorial is written by Xiaotian, editor of bitage (btc38. Com). The purpose is to let you get started and experience bitcoin. If you want to get better benefits through mining, You need to learn more about bitcoin pools and bitcoin mining strategies
4. Bitcoin mining pool
as mentioned above, the number of users of bitcoin mining is very large, and the output of bitcoin every 10 minutes is very limited, resulting in the situation that tens of millions of people scramble for a block. Therefore, if you use personal computers to mine alone, you may not be able to grab a block in a whole year, People have come up with a team mining method. The so-called team mining is the mining pool that we are going to talk about now
the mine pool is a server designed through a specific algorithm. All users connected to the mine pool server will form a team to mine. Although the performance of personal computers is small, the overall performance of thousands of people will become very powerful. In this case, the success rate of mining will be greatly improved, Once the team in the mine successfully creates a block, then all the team members will pay dividends according to the performance of each person's computer. For example, 1000 people are mining in the same mine pool. After digging out a block, the reward of n bitcoins generated by the block will be distributed according to the computer performance of the 1000 people. If your computer performance is strong, it may get 1 in 100; if the performance is backward, it may get 1 in 10000
in this case, the developer of the mine pool will generally charge 1% ~ 3% of the fee for each user as a handling fee, but because this method makes it more stable for everyone to get bitcoin, almost everyone will choose to mine in the mine pool instead of mining alone
as mentioned in the mining tutorial above, the mine pool provided free of charge in the bit age adopts the P2P technology architecture and does not charge any fees to users. It is one of the mainstream mine pools. In addition, there are BTC guild and deepbit, which are also very popular. Although the design of each mine pool is not the same, but the use method is basically the same and simple, so this tutorial will not do further description, you can explore by yourself. Even though Xiaobian has configured the mine pool and port provided by bit era for you by default in the previous tutorial, in order to let you have a deeper understanding of the mine pool, here are several mainstream mine pools for you to choose:
bit mine pool (free, recommended by Xiaobian) | bitcoin.cz (suitable for novices) | BTC Guide (the oldest brand) | deepbit (stable and efficient) | f2pool (domestic)

2. First of all, we need to find a mine pool which is easy to operate and proces stable output. The function of the mine pool is to subdivide the data packets for each terminal. We can pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through a precise algorithm
there are some points for attention in account setting. It is suggested to set a common account in e-mail
then there is the most important miner account setting. Miner obviously refers to CPU or GPU. You need to set an account for each CPU or GPU. Suppose you have two hd7990, you need to set four different accounts for four GPUs
after the account registration, it's time to take the second step. Download the bitcoin miner. Here we recommend the small and easy-to-use guiminer, which can support CPU, oepncl, CUDA and other computing modes. Your CPU and graphics card can achieve maximum performance
guiminer, a bitcoin miner, still needs to make certain settings. After the interface is changed to Chinese, it will be very simple
if the setting is correct, click the "start mining" button, the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, and you can also monitor the state through gpu-z or graphics card driver
the computing power displayed by guiminer is only a theoretical value. To know the actual output of bitcoin, you need to log in to the mine pool website, btcguild, to monitor your account information
now let's assume that you have g up several bitcoins, which naturally exist in btcguild, a foreigner's website. They can't be traded or converted into paper money for the time being
the functions provided by bitcoin China trading platform are clear at a glance, and you can understand them as soon as you read them, so you don't need to introce them any more. After you register, you can study them slowly
click the "bitcoin recharge" function of bitcoin China trading platform, and the system will provide you with a one-time bitcoin digital wallet address. This address can only be recharged once (for security reasons of the platform). After successful recharge, it will be invalid, and then the system will provide you with another address. Remember to update the wallet address in time every time, Otherwise, it will lead to recharge failure or loss
OK, now we import bitcoin from foreign websites into bitcoin China website, and it's up to you to deal with it. Keep it for appreciation, listing and selling, and exchange it for RMB. Specific how to operate, this Chinese website is easy to operate, we slowly study it
finally, let's talk about the equipment used in the bitcoin mining test. At first, I thought it was just an ordinary hd7870, but its computing power was much better than that of the ordinary hd7870. The key is that guiminer recognized it as the Tahiti core, which is the only core of hd7900 series. Looking at gpu-z, the card originally had as many as 1536 stream processors, Generally, the hd7870 of Pitcairn core has only 1280 stream processors. No wonder Dylan's graphics card has super computing power
for friends who hang up for a long time, performance is not the most important, and stability is the most important.

After the computing power of the whole network has been improved to a certain extent, the probability of getting rewards is too low, so that some geeks on "bitcoin talk" can develop a method that can combine a small amount of computing power and operate jointly, and use this method to build websites

in this mechanism, no matter how much computing power an indivial miner can use, as long as he participates in mining activities by joining the mine pool, no matter whether he has successfully mined effective data blocks, he can get a small amount of bitcoin reward through his contribution to the mine pool, that is to say, many people cooperate in mining, and the bitcoin reward is shared by many people according to their contribution

as of January 2019, the top five bitcoin pools in global computing power are btc.com, pool, antpool, flush pool, and f2pool. At present, about 70% of global computing power is in the hands of Chinese miners

extended data:

handling charge:

bitcoin miners will charge a small amount of fees for most transactions, the main purpose of which is to prevent people from sending a large number of boring small transactions and wasting network resources. At present, most of the handling charges for each transaction are & T 3647; 0.0001/kb (0.0001btc / KB). In fact, after 0.9.0, the default handling charge will be reced to & 3647; 0.00001/KB(0.00001 btc/KB)

because the amount of data occupied by most transactions is less than 1 kilobyte, generally speaking, the amount of data is less than 3647; 0.00001 (0.00001 BTC / KB) is enough. At the same time, in the future, when the bitcoin block rewards are less, the service charge will become the main source of miners' income, and the service charge of bitcoin will be related to the number of bytes occupied by the transaction

at present, the calculation standard of service charge in bitcoin system is not mandatory, so users can not give any service charge when the transaction is in progress

however, most miners usually give priority to the transaction with higher handling charges when building data blocks, so that they can get higher remuneration when mining is successful. Therefore, the transaction without any handling charges may take a long time to be processed and incorporated into the blockchain

in addition, e to the block capacity limit of 1MB and the recent increase in bitcoin transaction volume, the handling charges have increased significantly, and the waiting time for the transaction to be confirmed has also become much longer

4. The main reason is that the distribution mode of bitcoin is different: according to the operation mode, the common bitcoin pools are as follows: PPLNs, PPS, DGM, P2P ool, etc.

PPLNs: (the purest Group Mining) full name is pay per last n shares, which means "pay income according to the past n shares", which means that once all miners find a block, You will allocate the currency in the block according to the proportion of each person's own shares Share means share)

in PPLNs mode, luck is very important. If the mine pool can find many blocks in a day, then everyone's dividend will be very large. If the mine pool can't find any blocks in a day, then everyone will have no income

PPS: pay per share mode --- this mode is to pay for each share immediately. The expenditure comes from the existing bitcoin funds in the mine pool, so it can be withdrawn immediately without waiting for the block generation or confirmation. In this way, the operation behind the scenes of the pool operators can be avoided. This method reces the risk of miners, but transfers the risk to the pool operator. Operators can charge fees to make up for the possible losses caused by these risks

in order to solve the problem that PPLNs sometimes has a high profit and sometimes has no profit, PPS adopts a new algorithm. PPS estimates the daily available mineral resources of the mine pool according to the proportion of your computing power in the mine pool, and gives you basically fixed income every day

do you feel that this is a stable job? In fact, in order to avoid the risk of loss, the PPS model often charges a high handling charge of 7% - 8%< DGM: Double geometric method. It combines PPLNs and geometric reward type, so that the pool operator can avoid part of the risk. The pool operator will collect part of the excavated currency in a short time, and then return it to the miners with normalized value, such as charge and discharge of electric capacity. If you are lucky, you will get less money for each block and more money for poor luck

175btc: the mining node of 175btc works on a shares chain similar to bitcoin blockchain. Because there is no center, it will not be attacked by DOS. Unlike other existing mine pool technologies, each node's working block includes bitcoin paid to the owner of shares in the early stage and the node's own bitcoin. 99% of the reward (50btc + transaction cost) will be distributed equally to miners, and the other 0.5% will be awarded to those who generate blocks

bitcoin home has a detailed introction.

5. The computing power and block output of the whole network can reach taobit http://www.taobtc.net/ See
1. First of all, as a node mine pool, the mine pool construction itself needs to add node files, showing the number of connections below the bitcoin wallet. After adding nodes, the number of connections can reach dozens or even more, depending on how many nodes you add, effectively recing invalid shares
2. How to fix the calculation difficulty of mining equipment for miners? Set it in your mining equipment startup bat
for example, if your single mining equipment is 10g, you can add / 1000 + 10 after the user name (wallet address) in the bat file. For example, in my bat - / 1000 + 10-p1, what does that mean? This means that your equipment is 10g computing power, and you use a fixed difficulty of 10g in p2pool mining. If you are a 1g device, write / 1000 + 1 at the back, so the difficulty is fixed and the efficiency of the device is effectively improved.

6. How to choose mine pool

ore pool cost

at present, the allocation modes of ore pool mainly include PPS, PPS +, FPPS, PPLNs and solo mode

in the corresponding allocation method, the mine pool charges part of the income of the miners at a certain rate as the mine pool fee

PPS: the income is stable. As long as the mining machine works normally, there will be income. The income is related to the submitted workload, and has nothing to do with the lucky value of the ore pool and the transaction fee

PPS + (pay per share plus) settlement method is an improvement on the traditional PPS settlement method. Based on the traditional PPS settlement method, the distribution of miners' fees is increased

FPPS: full PPS, which allocates all block income including transaction fees. Compared with the traditional PPS settlement mode (no transaction fee allocation), it can increase the income by 10% - 20%

under the PPLNs (pay per last n shares) settlement mode, every effective block found in the ore pool is allocated according to the proportion of user computing power in the pool computing power in the past n difficulty cycles. In this way, the income of miners is related to the output of ore pool. The income of miners is unstable, but the long-term average income is higher

in solo settlement mode, all the income is distributed to the miners who dig out the block, and other miners do not participate in the distribution. The mine pool charges very little handling charge, which is used for the operation and maintenance of the mine pool< How to choose a mine pool:

1< Secondly, choose your distribution mode, pursue stability or high income. It is generally recommended to choose PPS or PPLNs of large ore pool< Finally, according to the distribution mode, select the supported ore pool, and choose the one with fast connection speed and good income

4. In addition, 1-2 spare ore pools are selected for emergency use.

7. The computing power and block output of the whole network can be found in
http://www.taobtc.net/
look at
1. First of all, as a node mine pool, the mine pool construction itself needs to add node files, which show the number of connections under the bitcoin wallet. After adding nodes, the number of connections can reach dozens or even more, depending on how many nodes you add, effectively recing invalid share
2. How to fix the calculation difficulty of mining equipment for miners? Set it in your mining equipment startup bat
for example, if your single mining equipment is 10g, you can add
/ 1000 + 10 after the user name (wallet address) in the bat file. For example,
- U
/ 1000 + 10
- P
1 in my bat, what does that mean? That is to say, your device is 10g computing power, and you use a fixed difficulty of 10G for mining in P2P pool. If you are a 1g device, write / 1000 + 1 at the back, so the difficulty is fixed and the efficiency of the device is effectively improved.

8. Network disk, the choice of 700 million people!!!

9. At present, the computing power of P2P pool nodes in the whole network is about 20t, but the actual utilization rate is only 10-15t, which wastes a lot of computing power
the computing power and block output of the whole network can be seen here http://www.taobtc.net/
a lot of computing power is wasted. The reason for this is also from the structure of the P2P pool. The P2P pool node will automatically adjust the difficulty of the pool according to the computing power of the workers' mining equipment. This process is quite fast, and the difficulty will be adjusted every few minutes, As a result, the mining equipment is easy to report errors, that is, it generates a lot of R, which reces the efficiency. The P2P pool is a PPLNs mode. You need to submit an effective share to get profit. After submitting an effective share, you can get all the blocks generated within 24 hours. The difficulty of effective share is relatively large. What I reflected in my pool is that 1g of computing power can't dig effective share at all
how to improve the efficiency of P2P pool

1. First of all, as a node mine pool, the mine pool construction itself needs to add node files, showing the number of connections under the bitcoin wallet. After adding nodes, the number of connections can reach dozens or even more, depending on how many nodes you add, effectively recing invalid share

/ 1000 + 10
- P
1 in my bat, what does that mean? That is to say, your device is 10g computing power, and you use a fixed difficulty of 10G for mining in P2P pool. If you are a 1g device, write / 1000 + 1 at the back, so the difficulty is fixed and the efficiency of the device is effectively improved.
