Dos for ore pool

1.

mining is perhaps one of the most important components of the bitcoin ecosystem. Miners need to solve complex mathematical problems, so as to ensure the smooth implementation of the transaction. These problems are so complex that they are difficult to solve even for extremely powerful computers. Computers need work and luck to solve these mathematical problems, just as miners dig underground. The chance of solving this problem correctly is about one in 13 trillion

bitcoin mining has two purposes. Firstly, by solving mathematical problems, bitcoin miners can verify the transaction information, so as to ensure the security and reliability of bitcoin payment network. Miners are the people who ensure that transactions are accurate and that there is no "double payment."

Secondly, when the computer solves these complex mathematical problems on the bitcoin network, the system will generate new bitcoin, which is similar to the process of mining gold from the ground. The reward is called "block reward", and after the event called "halving", its amount will be periodically halved. The newly discovered concept of bitcoin is an important part of bitcoin protocol. The bitcoin obtained by the miners is brand new and has never been in circulation before

since miners will eventually sell the bitcoin, it is also an important source of supply and liquidity. As chainalysis reports, many digital currency exchanges rely on miners to receive bitcoin and increase their liquidity. Typically, exchanges get about 88% of bitcoin from other exchanges, and bitcoin miners are the largest source of the remaining percentage. As you can imagine, there is fierce competition between exchanges to receive bitcoin directly from miners

further enlarge the map, most of the mining activities are only carried out in four provinces, the first two provinces are Xinjiang and Sichuan, accounting for nearly half of all bitcoin mining in China. Electricity prices are cheap and the weather is cold in these areas. This helps to keep mining profits and equipment cool ring the 24 / 7 operation and maintenance period of bitcoin mining

but this is nothing new for digital currency issuance. For many years, China has been a major market for bitcoin miners e to its cheap electricity and abundant resources. Bitmain, f2pool and Canaan are all located in China

whether this is a negative or positive message depends on your point of view. But for decentralized, distributed, unlicensed networks, geographic regions across multiple entities are more healthy for the entire ecosystem

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. Don't believe that there are still things like pie in the sky. If you join in the form of membership, you have to pay es or buy high priced procts. It is in line with the characteristics of pyramid selling to draw high profits from it by pulling people's hair off the line.

4. 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!

5. The storage miner of interstellar space mining is to save files, and at the same time to facilitate its upload and download, so the storage miner will require a lot of hard disk space, but also a lot of bandwidth, upstream and downstream peer-to-peer bandwidth.

6. Compared with the self built cluster, the transparency of selecting access to the mine pool is poor, and the investigation is also very difficult. There are even a large number of funds. The property rights of mining machinery and nodes are completely controlled by the mine pool side, and the operation fees of the mine pool side are also very high, and the annual rate of return is usually less than 2 times.

7. I understand that this belongs to two modes. Self built cluster is much better than access to the mine pool. It has its own independent property rights and nodes, and the cost is relatively low. However, access to the mine pool is different. The property rights of mining machinery and nodes are controlled by the mine pool side, and the operating costs are high, so we earn less, Another point is that the rate of return of self built cluster is much higher than that of access to the mine pool, so it is not necessary to access the mine pool if self built cluster can be used.

8. It is suggested that you should not join the mine pool if you can build your own cluster, because the self built cluster not only has its own independent property rights and independent nodes, but also controls the mining machinery completely in its own hands. Moreover, the cost is very low, and the theoretical annual yield is usually more than 6 times.

9. For small miners, it is suitable to choose a professional mine pool for mining, and can distribute the average income of the mine pool.

10. In order to find the resources from the vast sea of resources, it needs a strong computing power, and the requirements of memory and network are very high. In this case, our mining machine needs powerful computing power and large memory.
