How to dig bitcoin in lilac browser
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.
mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary
however, most of the new digital cryptocurrencies after 2016 do not need mining, and most of them use POS mechanism, and some of them are one-time mining, such as Ruitai.
When bitcoin nodes connect with each other, they will get transactions they don't have from each other. But because bitcoin has accumulated a large number of transactions for a long time, it is very difficult for two nodes to compare which transactions you are missing / which transactions I am missing one by one
to solve this problem, Nakamoto Tsung invented the important technology of block chain. Nodes use blocks to synchronize transactions, which ensures the data consistency of all nodes, and ensures the uniqueness of the blockchain by competing for block packing rights (that is, mining)
① a block and blockchain
a packet formed by a transaction over a period of time is called a block. On average, bitcoin generates a block every 10 minutes, and each block is linked to the previous block to form a blockchain
② the transaction data is synchronized with the block as a unit
the block is numbered from 1, so after node a connects with node B, it is convenient to synchronize the transaction data as long as the block number height of both parties is checked. For example, if node A's own block height is 100 and node B's block height is 110, all it needs to do is request B to synchronize the 10 blocks 101-110<
③ reward for packed blocks
in order to ensure that there are nodes to pack bitcoin transactions, bitcoin rules stipulate that nodes of packed transactions will receive bitcoin as reward
A. part of the package reward comes from the transaction fee paid by the transaction creator (100-1000 transaction fee per KB)
B. the other part comes from the initial distribution of 21 million bitcoins. At the beginning, the reward is 50 bitcoins for each block. After that, the reward will be halved for every 210000 blocks (about four years). Until about 2140, the reward for each block is less than 1, and the total reward for each block is 21 million bitcoins, This is the source of the total amount of 21 million bitcoins (2099999.97690000 to be exact)
after 2140, the package reward will only come from the transaction fee paid by the transaction creator<
④ competition for block packing right
node packing transaction only needs to consume very low-cost network and computing resources. The existence of packing reward (at present, the packing reward for each block is 25 bitcoin, about 40000 yuan), makes a large number of nodes want to pack transactions. In order to ensure the uniqueness of the blockchain, bitcoin rules stipulate that nodes use a method similar to "coin tossing" to compete for the right of transaction packaging. Nodes constantly toss coins. Whoever first throws the results that meet the rules will get the right to pack the transaction in this block, as well as the package reward of this block
1. First of all, connect the network cable, plug the network cable into the network cable interface of the mining machine, and remember to plug it tightly. Only when the miner is connected to the Internet, there is no limit to the broadband
extended data:
shortcomings
first, the vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
Second, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed Thirdly, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading Fourthly, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthlessI wish you progress in your study! Hope to adopt Hee hee
Installing bitcoin software is like playing games. Anyone can run software on special hardware and become a bitcoin miner
for example, mining software monitors transaction broadcast through P2P network and performs appropriate tasks to process and confirm these transactions
new transactions need to be included in a block with mathematical workload proof to be confirmed
this kind of proof is difficult to generate because it can only be generated by trying billions of calculations per second. Miners need to run these calculations before their blocks are accepted and rewarded
as more people start mining, the difficulty of finding effective blocks will be automatically increased by the network to ensure that the average time to find blocks is kept at 10 minutes. Therefore, the competition for mining is very fierce, and no indivial miner can control the content contained in the block chain
because it is necessary to recalculate the workload proof of all subsequent blocks. When two blocks are found at the same time, the miner will process the first block received, and once the next block is found, it will be transferred to the longest block chain
