Double U ore pool
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
Mining is perhaps one of the most important components of the bitcoin ecosystem. Miners need to solve complex mathematical problems, so as to ensure the smooth implementation of the transaction. These problems are so complex that they are difficult to solve even for extremely powerful computers. Computers need work and luck to solve these mathematical problems, just as miners dig underground. The chance of solving this problem correctly is about one in 13 trillion
bitcoin mining has two purposes. Firstly, by solving mathematical problems, bitcoin miners can verify the transaction information, so as to ensure the security and reliability of bitcoin payment network. Miners are the people who ensure that transactions are accurate and that there is no "double payment."
Secondly, when the computer solves these complex mathematical problems on the bitcoin network, the system will generate new bitcoin, which is similar to the process of mining gold from the ground. The reward is called "block reward", and after the event called "halving", its amount will be periodically halved. The newly discovered concept of bitcoin is an important part of bitcoin protocol. The bitcoin obtained by the miners is brand new and has never been in circulation beforesince miners will eventually sell the bitcoin, it is also an important source of supply and liquidity. As chainalysis reports, many digital currency exchanges rely on miners to receive bitcoin and increase their liquidity. Typically, exchanges get about 88% of bitcoin from other exchanges, and bitcoin miners are the largest source of the remaining percentage. As you can imagine, there is fierce competition between exchanges to receive bitcoin directly from miners
further enlarge the map, most of the mining activities are only carried out in four provinces, the first two provinces are Xinjiang and Sichuan, accounting for nearly half of all bitcoin mining in China. Electricity prices are cheap and the weather is cold in these areas. This helps to keep mining profits and equipment cool ring the 24 / 7 operation and maintenance period of bitcoin mining
but this is nothing new for digital currency issuance. For many years, China has been a major market for bitcoin miners e to its cheap electricity and abundant resources. Bitmain, f2pool and Canaan are all located in China
whether this is a negative or positive message depends on your point of view. But for decentralized, distributed, unlicensed networks, geographic regions across multiple entities are more healthy for the entire ecosystem
