Falsification of calculation power in mine pool

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

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. Currency holding capacity of global mineral pool alliance = (ranking of wallet deposit) ÷ All wallets in the mine pool × 50% of the mining volume of the ore pool
ranking of the account balance (currency holding) of the global ore pool Alliance (multiple accounts may have the same name, but the next place will jump and grow synchronously, as the weight of this part of the issue)

4. 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.

5. 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.

6. After a period of time, only 1% of the water is pumped by Aiminer ring its operation, and there is no stealing calculation power. If other people recommend your water free software, you should be careful. If you really don't pump water, you will steal the calculation power! There's no free lunch in the world. You'll lose a lot if you take advantage of it. If it is found that the computing power of the mining software is too different from that of the ore pool. Generally e to the network reasons, or the existence of stolen computing power in the mine pool, whether it is fish pool or spark, there will be stealing 5-10% of the computing power. You can also check whether you dig with WiFi, which will cause frequent packet loss.

8. Computing power will fall, but if the technology is relatively stable, most of the miners with qualified operation and maintenance ability will recover within the specified time after occasional loss of computing power, so as to avoid huge punishment. If a large number of confiscated pledged currencies are not recovered within the specified time, it means that the technology of the manufacturer is not only unstable, but also the operation and maintenance ability is extremely poor. We have to choose carefully.

9. Because filecoin & IPFs punishes the loss of computing power for more than 24 hours and confiscates all the pledged and locked positions for more than 14 days, it is particularly important to note that if a node managed by a manufacturer is fined and confiscated a large number of pledged currencies e to the loss of computing power, it is absolutely not allowed to choose!
