How to exit ubank pool
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)
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.
Mine pool refers to:
as the computing level of the whole bitcoin network continues to rise exponentially, a single device or a small amount of computing power can not get the block reward provided by the bitcoin network on the bitcoin network
after the computing power of the whole network has been improved to a certain extent, the low probability of getting rewards has prompted some geeks on "bitcoin talk" to develop a method that can combine a small amount of computing power and operate jointly, and the website established in this way is called "mine pool"
extended data:
the existence of the mine pool reces the difficulty of bitcoin and other virtual digital currency mining, reces the mining threshold, and truly realizes the bitcoin mining concept that everyone can participate in
but its disadvantages are also very obvious, because computing power is connected to the mine pool. As a mine pool, it will have huge computing power resources. In the bitcoin world, computing power represents the bookkeeping right, and computing power is everything. If the computing power of a single mine pool reaches more than 50%, it will be easy to launch 51% attacks against virtual digital currencies such as bitcoin, The consequences are very terrible:
the mine pool can make the mine pool with 49% of the remaining computing power have no harvest, instantly quit the competition and go bankrupt. The mine pool's computing power exceeds 50%. If 51% attack is launched, it will easily occupy all the effective computing power of the whole network
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
