how to mine a mine pool
the location of a mine pool is also very particular. It's not that a mine pool can be built anywhere, but it needs early-stage capital investment. A mine pool is to combine a single mining machine together. Because of the collection of many miners' computing power, the computing power of the mine pool accounts for a large proportion, and the probability of digging bitcoin is higher. The mine pool will distribute rewards according to the contribution value of each equipment
there are many mines all over the world, and the scale of each mine varies from big to small. Generally, small mines no longer have great advantages. Large mines have many miners for mining. For each miner, he can join any mine or join multiple mines at the same time, The first task of the mine pool is to distribute the income to the miners
(1) PPLNs method
this method gathers the shares g by all miners together. Whenever a certain amount of shares is accumulated (generally 30 million shares), the mine pool will allocate the profits of the previous stage to the miners according to the proportion of contribution
in this way, the income of miners depends entirely on the time needed to dig 30 million shares in the mine pool. If you are lucky, you can dig them in a short time, then the income of miners will be more, otherwise it will be less. In return, the pool charges a 3% tax
(2) PPS mode
for users, the income of this mode is relatively stable
the profit mainly depends on the miner's mining speed. As long as the mining speed is stable, the corresponding profit can be obtained, and the profit is real-time, that is, the mine pool will pay the profit for the miner while the miner is running
obviously, every time a block is calculated, the mine pool has paid for all the miners. If the block fails in the subsequent confirmation link, all the losses will be paid by the pool operator. Therefore, this method reces the risk of the miners, but transfers the risk to the pool operator
therefore, usually the ore pool can charge a handling fee to make up for the possible losses caused by these risks. In this mode, the tax of the ore pool is 7.5%
the above is about how to mine. The difficulty of mining has greatly increased, but the mining army is expanding. If the basic equipment does not meet the standard, it will be difficult to gain in the mining instry, because the value of the virtual currency may not be equal to the price of an equipment, and many miners are not just digging bitcoin, Instead, we choose other virtual currencies to mine.
Mining is the use of bitcoin mining machine, which is used to earn bitcoin
one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, can surpass the single graphics card of most users
and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining
bitcoin mining process:
1. To find the ore pool
to start mining, there must be a ore pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm
2. Download bitcoin miner (software)
in fact, there are many kinds of this miner, you can go to the official website to download
3. Setting mining software is a green software. After installation, we can set the language first to facilitate further setting. Next, you need to set the server, user name, password, equipment and so on. Generally, the server chooses a better network from BTC guide series, and the user name and password are set by ourselves before
4, bitcoin mining start
when we confirm that all settings are correct, click the "start mining" button to start bitcoin mining, and then the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, you can monitor the state through gpu-z or graphics card driver
graphics card, motherboard, power supply, CPU, memory, hard disk (more than 60g SSD is recommended), extension cable, adapter cable, etc
among them, the graphics card determines the speed of mining, and the motherboard and power supply largely determine the stability of mining machine operation.
bitcoin is a kind of point-to-point e-cash system, more directly, node to node. Each transaction is broadcast by the originator to the nodes around it, and then broadcast to the nodes around it after receiving it, and finally spread to the whole network
every bitcoin wallet is a node, and the node with a complete blockchain ledger is called the whole node. In October 2017, there were about 9300 nodes in the bitcoin network, which were responsible for broadcasting and verifying bitcoin transfer transactions. After the transfer transaction occurs, all nodes broadcast to the whole network. After the mining node verifies that the transaction is correct, it will be recorded in the blockchain ledger. The United States, Germany and France have the largest number of bitcoin nodes, with China accounting for about 5% of the world's total nodes Data source: bitcodes. 21. CO) running bitcoin node does not provide any reward, and it does not need the whole node to transfer bitcoin, so the total number of bitcoin nodes only accounts for a small part of the node number.
Bitcoin mining is a process of using computer hardware to calculate transaction confirmation and improve security. Bitcoin is a reward for miners to calculate and confirm
bitcoin also has a hype mode. Similar to bitcoin, there are also flow ores. Flow ores also have ways of trading and speculation, but the mining principle of flow ores is different from bitcoin. Flow ores mainly collect the idle bandwidth of miners and give them rewards
in fact, the blockchain technology adopted by bitcoin is more valuable than itself. This is a new way of information storage. The data is stored in all devices connected to the network. When new devices join, the information will be updated automatically, and all devices have the right to read the information
to understand the significance of bitcoin from the perspective of currency, we need to understand the currency itself first, and then compare it with the characteristics of bitcoin. After comparison, I think that bitcoin is a very high-quality currency, but some people don't think it is. They mainly question the formation mechanism of bitcoin and the lack of national credit as guarantee. They think its foundation is relatively weak
at present, there are quite a lot of arguments about bitcoin in academic circles. For example, if the total amount of bitcoin is certain, then whether it will cause deflation or inflation has different views. I think it's deflation, and the value of bitcoin will be higher and higher
at present, bitcoin still means a little bit of a safe haven currency. When the news of brexit came out, the transaction price of bitcoin rose by 20% - 30% to about 4500 yuan / piece
the biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
the concept of bitcoin was first proposed by Nakamoto in 2009. Bitcoin, also known as bitcoin, is an open source software designed and released according to the idea of Nakamoto Tsung, and a P2P network built on it. Unlike most currencies, bitcoin does not rely on a specific central issuing institution. It uses distributed databases throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation
1. I now have a 100 yuan personal name coin in my hand Bitcoin)
2.. Who cares about the official account? But you need to guess the number of the money in the comments Mining, random filling, numerical solution)
try your best to guess, and you get 100 yuan in full - personal mining
pay money to gather some people to guess together - mining field
gather people you don't know to guess together, and allocate the 100 yuan in proportion through the number of guesses -
the above is a simple example of analogy, of course, You followed and guessed the number of 100 yuan in my pocket, I promise you
so what's going on with bitcoin mining

when Zhang San wants to transfer 1000 yuan to Li Si's B account through a account: ① Zhang San roars: attention, I use a account to transfer 1000 yuan to Li Si's B account. ② The villagers near Zhang San listened to Zhang San's voice and checked whether Zhang San's a account had enough balance. ③ After passing the inspection, the villagers write on their account books: account a transfers 1000 yuan to account B, and modify the balance: account a balance = 3000-1000 = 2000 yuan, account B balance = 2000 + 1000 = 3000 yuan. ④ The villagers near Zhang San told the villagers far away about the transfer, and passed it on until everyone knew about the transfer, so as to ensure the consistency of everyone's account books. Smart if you must have found out, in step 2, if Zhang San roars, and the villagers nearby pretend not to hear him, and do not check the account, then the system will stop working? In order to solve this problem, the village decided after discussion that whoever first confirmed Zhang San's voice would get 500 yuan. So everyone put up their ears and monitored every movement in the village. It's really a matter of grass and trees. Someone in the comment area asked, where did the 500 yuan come from? I would like to give a brief answer here. 1. On average, bitcoin generates a block every 10 minutes. The number of transactions that can be packaged in this block is limited. Let's count it as 800. However, absenteeism will not give you a package deal and broadcast for no reason, so you need to charge a handling fee. Moreover, because there are many people in the transaction, whose transaction to pack first also depends on the level of handling charges. So you can see that bitcoin is hot now, and the handling charges are going up. 2. We all know that the total number of bitcoin is 21 million, and the issuing mechanism is decreasing year by year. If absenteeism is the first one to successfully package this block and broadcast, and it is the longest chain, he will be rewarded. At present, there are only 12.5 bitcoins. It started with 50. It's decayed twice. Of course, there are small problems, such as why the longest chain is needed, how to determine the longest chain, and which chains will be abandoned? If you are interested, let's talk about it further. The above is the reward for absenteeism. Updated on December 8, 2017. In the world of bitcoin, one block is generated about every 10 minutes. All mining computers are trying to package the block and submit it, and the first person who successfully generates the block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes. Well, then the story above tells that Zhang San's roar shocked the whole village, and everyone said that they were the first to hear Zhang San's voice. Who should I give the 500 yuan to? So the village discussed the new regulations, and needed evidence to prove that it was Zhang San's voice. Zhang San's cry contains specific sound data, which will be given to whoever breaks it first. In the bitcoin world, this is a new concept, consensus mechanism. Bitcoin decides the bookkeeping right through the consensus mechanism of workload proof. Generally speaking, the one who proves his workload is the biggest is responsible for bookkeeping. The amount of work is reflected by calculating the hash value of the bitcoin block header that meets a certain standard. The block header usually contains the hash value of the previous block, Merkle root, timestamp, difficulty target, and a filled random value. The node that tries to fight for the bookkeeping right is called mining node. The mining process is to find a random value that can fill the block head of this area, so that the hash value of the block head can meet a certain standard
