Mine pond or fish pond
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
1. Machine: two ant double blade mining machines (rated speed: 180gh / s, rated power consumption: about 360W)
2. Network: ordinary family 8m broadband connection
3. Test time: from 11:00 p.m. on January 27 to 7:00 a.m. on January 28, 2014, a total of 8 hours
4 Comparison:
a miner in btcguild (EU stratum. Btcguild com:3333
the average speed of 8 hours is 175.92gh/s, and the profit is 0.01424974
one miner operates in f2pool (stratum)+ tcp://stratum.f2pool.com : 3333)
8 hours average speed 180gh / s, revenue 0.01230566
5 The test results are expected (the theoretical value under the difficulty of the day does not consider other factors):
the profit of an ant double blade miner in btcguild mine is 0.00194408 more than that in f2pool mine in 8 hours, 0.00024301 more per hour, 0.00583224 more in 1 day (24 hours), and 0.1749672 more in each month (30 days)
This is the pool share in the past three months:
look at the balance sheet, profit, etc. first, go to this company to look at its report. Look at the profit from its sales revenue.
for example, what is the proportion of profit. From the size of gross profit, we can know how a company's buyer is.
if the proportion of gross profit and sales is large, From the dividend, we can see whether the company pays attention to investment,
or short-term profits. From the ratio of working capital and current liabilities, we can see the company's ability to repay others
if it is too low, it can explain the management efficiency of the company from the side. If it is too high, it also shows that the company is not good at investment.
in other aspects, you can understand its background, evaluate its ability, and whether it is suitable for the company from the perspective of the company's managers. Or from the past performance, you can see how the company's loans are. If there are too many, there will be risks, or lack of confidence. Dividing the net profit by the sales volume, we can know the consumption management of the company in other aspects, such as water and electricity, office supplies, etc. if the result is relatively high, it means that the company is economical and orderly. If it is relatively low, it means that the efficiency of the company is not high,
if there is a significant increase, the company is in the right direction.
