How much is the calculation rate of ore pool

1.

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

2. The main reason is that the distribution mode of bitcoin is different: according to the operation mode, the common bitcoin pools are as follows: PPLNs, PPS, DGM, P2P ool, etc.

PPLNs: (the purest Group Mining) full name is pay per last n shares, which means "pay income according to the past n shares", which means that once all miners find a block, You will allocate the currency in the block according to the proportion of each person's own shares Share means share)

in PPLNs mode, luck is very important. If the mine pool can find many blocks in a day, then everyone's dividend will be very large. If the mine pool can't find any blocks in a day, then everyone will have no income

PPS: pay per share mode --- this mode is to pay for each share immediately. The expenditure comes from the existing bitcoin funds in the mine pool, so it can be withdrawn immediately without waiting for the block generation or confirmation. In this way, the operation behind the scenes of the pool operators can be avoided. This method reces the risk of miners, but transfers the risk to the pool operator. Operators can charge fees to make up for the possible losses caused by these risks

in order to solve the problem that PPLNs sometimes has a high profit and sometimes has no profit, PPS adopts a new algorithm. PPS estimates the daily available mineral resources of the mine pool according to the proportion of your computing power in the mine pool, and gives you basically fixed income every day

do you feel that this is a stable job? In fact, in order to avoid the risk of loss, the PPS model often charges a high handling charge of 7% - 8%< DGM: Double geometric method. It combines PPLNs and geometric reward type, so that the pool operator can avoid part of the risk. The pool operator will collect part of the excavated currency in a short time, and then return it to the miners with normalized value, such as charge and discharge of electric capacity. If you are lucky, you will get less money for each block and more money for poor luck

175btc: the mining node of 175btc works on a shares chain similar to bitcoin blockchain. Because there is no center, it will not be attacked by DOS. Unlike other existing mine pool technologies, each node's working block includes bitcoin paid to the owner of shares in the early stage and the node's own bitcoin. 99% of the reward (50btc + transaction cost) will be distributed equally to miners, and the other 0.5% will be awarded to those who generate blocks

bitcoin home has a detailed introction.

3. According to the official website of coin'an mining pool, BTC's calculation power has reached 1.75e, 36053 effective miners, ranking 11th at present, OK's calculation power is 6.89e, and Huo's calculation power is 4.75e. At present, there is still a big gap in the coin'an mining pool. However, as a bystander, you should have a unique vision. Looking at the ups and downs of the previous coin circle, the development and launch of various new technologies, although coin an is late, it can always make the latecomer rank first. It probably doesn't take long for this ranking to change.

4. How to choose mine pool

ore pool cost

at present, the allocation modes of ore pool mainly include PPS, PPS +, FPPS, PPLNs and solo mode

in the corresponding allocation method, the mine pool charges part of the income of the miners at a certain rate as the mine pool fee

PPS: the income is stable. As long as the mining machine works normally, there will be income. The income is related to the submitted workload, and has nothing to do with the lucky value of the ore pool and the transaction fee

PPS + (pay per share plus) settlement method is an improvement on the traditional PPS settlement method. Based on the traditional PPS settlement method, the distribution of miners' fees is increased

FPPS: full PPS, which allocates all block income including transaction fees. Compared with the traditional PPS settlement mode (no transaction fee allocation), it can increase the income by 10% - 20%

under the PPLNs (pay per last n shares) settlement mode, every effective block found in the ore pool is allocated according to the proportion of user computing power in the pool computing power in the past n difficulty cycles. In this way, the income of miners is related to the output of ore pool. The income of miners is unstable, but the long-term average income is higher

in solo settlement mode, all the income is distributed to the miners who dig out the block, and other miners do not participate in the distribution. The mine pool charges very little handling charge, which is used for the operation and maintenance of the mine pool< How to choose a mine pool:

1< Secondly, choose your distribution mode, pursue stability or high income. It is generally recommended to choose PPS or PPLNs of large ore pool< Finally, according to the distribution mode, select the supported ore pool, and choose the one with fast connection speed and good income

4. In addition, 1-2 spare ore pools are selected for emergency use.

5. This is the way to calculate the income of coin'an mining pool; FPPS = theoretical income of average daily calculation power * (1 + transaction rate) * (1-pool handling rate).

6. According to the operation principle of the miner, the miner will continue to accept the tasks assigned by the mine pool, and return the calculation results to the mine pool. However, there is a delay in the communication between the mine machine and the mine pool network, and the invalid submission caused by the network delay is called the rejection rate.

7. Now that bitcoin has been basically banned in China, you are still working on this thing. Er, are you hopeless or hopeless

8. Now the domestic mine pool has accounted for more than 60% of the computing power of the whole network, but it is no longer the only one. Mining is basically the Chinese has the final say. If several large mines unite to launch a 51% attack, it is completely feasible in theory, but it is not in their interests, so they will not do it. It's not a good thing that computing power is in the hands of a mining pool. It is very dangerous to concentrate too much on any kind of currency. However, there are also some coins that do not need to be mined, such as Ruitai.

9. The computing power of a single machine. The difficulty is fixed, there is no how to come, just like the human ape purification.
