Is it better if the calculation power of the mine pool is higher

1. mining pools are arranged according to computing power. For example, the computing power of digyi mining bitcoin mining pool accounts for about 4% of the total network computing power, ranking among the top ten mining pools in the world. The four technology blockchains are relatively good.
2.

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

3.

This is the share of ore pool in the past three months:

{rrrrrrr}

but in fact, it's of little use. It's just the difference between 100 yuan and 100.5 yuan. If your calculation power is really big, it may be much worse, but if it's ordinary, it's not much different. It is more important to choose one with low or free service charge

4.

This is the pool share in the past three months:

5. 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.
6. 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.
7. As an old miner, after years of comparison, Xinxiu mine and omiyun mine are good, not only with high income, but also with good service
8. The question is very general
what is sewage
what process should be used
if it is biochemical treatment of AO and AAO,
BOD / cod > 0.4 is OK,
otherwise, the biochemical treatment effect is not good
9. It doesn't matter, because the number of data blocks in all mines is global (each data block contains about 25 bitcoins). The only important thing is which mine is relatively stable and will not be offline e to a large number of visits. In fact, few of them are offline
the old mines are very stable, such as bitcoin.cz and BTC guide.
