Disinfection of fish pond and mine pond

1. < UL >

this is mainly e to the 51% attack, because before some of the world's well-known mines, e to the low rate and convenient use, many miners went to those large mines to mine. As a result, the computing power of the mines soared, approaching or even exceeding 51% of the global computing power many times

bitcoin community has also raised a big discussion about 51% attack for many times,. The mine pool operators also called on the miners to move to other mines in a responsible manner, and finally 51% of the attacks were solved. Many of China's miners have moved to fish ponds

most of the new miners have joined the fish pond because they don't know about the global mine ponds, and many of the previous mines have died e to poor management

2. In terms of physical fitness and material stacking, a-card is still resistant to operation, and double precision is also high in a-card, so mining efficiency is high, and a-card will be selected for basic mining

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

4. Comparison of two ant double blade mining machines in btcguild and f2pool mining pool (personal test for reference only)

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:

6. Because indivial mining is difficult to meet the demand, the global computing power is increasing, and it is difficult for a single device or a small amount of computing power to dig bitcoin again. It is also a combination of a large number of mining machines to form a mine pool. The computing power of the mine pool is very powerful, and it can also ensure that virtual currency can be g more quickly. So how can the mine pool dig? Let's have a look
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.

7. Fish pond f2pool is the earliest mine pond in China. It was closed for a period of time e to poor management, probably in July last year, but it was opened again soon. They are not only mining pools, but also mining machines. Shenyu mining machine failed because of the chip problem. In 2015, we set up a Wright coin miner and crowdfunding
there has been no major safety accident in the fishpond f2pool. In addition, 51% of the problems often occur in large foreign mines, which also gives the fishpond f2pool opportunities for rapid development. They are all people in the circle, and they also work as information websites and have a wide range of contacts.

8. In fact, this is mainly e to 51% attacks. Because in the past, e to the low rate and convenient use of some well-known mines in the world, many miners went to those large mines to mine, resulting in a sharp rise in the computing power of the mines, which was close to or even more than 51% of the global computing power for many times. Bitcoin community has also raised a big discussion about 51% attack for many times. The mine pool operators also called on the miners to move to other mines in a responsible manner, and finally 51% of the attacks were solved. Many of China's miners have moved to fish ponds. After all, China's contribution to the global computing power is also very objective. Most of the new miners have joined the fish pond because they don't know about the global mines. Many of the previous mines died e to poor management. However, at present, the computing power of coin net's mine pool and bitcoin China's mine pool are also very close to fish pool, and the computing power of fish pool does not take much advantage. Bitcoin house has reported 51% attacks on bitcoin.
