Mining machine and pool
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
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.
the mining pool is the necessary infrastructure for the exploitation of P2P cryptography virtual currency such as bitcoin (digital currency). It is generally an open team mining server. Its significance is to improve the stability of bitcoin mining and stabilize the miners' salary. At present, the most powerful mining pools in the world are f2pool, antpool, BW pool, BTCC pool and bitfury. Except for bitfury, the rest are from China
with more and more people participating in mining, the computing power of bitcoin network is rising, and it is difficult for a single device or a small amount of computing power to dig bitcoin again. At this time, the mine pool was born
operation principle of bitcoin mine pool
the ore pool is responsible for information packaging, and the access mine is responsible for competing for bookkeeping rights
e to the collection of the computing power of many miners, the computing power of the mine pool accounts for a large proportion, and the probability of digging bitcoin is higher
for example
suppose 1 million people participate in bitcoin mining, and the whole network has 400p computing power, of which 90% of the miners have less than 1p (1000t) computing power. If a 1t miner is put into operation, it will account for 1.400000 of the whole network's computing power. Theoretically, every 400000 10 minutes can dig a block, that is, only 7.6 years can dig a block, and then get 50 bitcoins at a time
then, if I find another 9 miners with 1t dynamometer and reach an agreement, we will have a total of 10 people, and any one of them will be divided equally according to the proportion of each person's computing power, then we are a whole. With a total of 10t computing power, we can dig a block in 0.76 years on average, Then we have five bitcoins mined in 0.76 years. What if we organize 100 people, 1000 people, 10000 people or even 100000 people
if it is 100000 people, I can dig one block in 100 minutes on average. As a member of the team, my income will tend to be stable
this is the basic principle of the mine pool, that is, everyone forms a team to mine bitcoin, you can refer to the "buy together" in the lottery
of course, the above is only a simple description of the basic principles and properties of the ore pool, and the actual situation will be very complicated
the ore pool is a fully automatic mining platform, that is, the ore machine is connected to the ore pool to provide computing power and obtain profits
the bitcoin reward generated by mining in the mine pool will be distributed according to the proportion of each miner's contribution to computing power
compared with single mining, adding to the ore pool can obtain more stable income
I hope this answer will help youfor example, a zero coin mine can be g 24 hours by a miner. According to the calculation power of the miner, an equal amount of coins can be g out
