What do you mean by pool delay

1.

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

2. At present, with the increase in the number of people mining in various currencies, the difficulty is also increasing. If you mine with a single computer, the possibility of digging out a block is relatively small. Take BTC for example, it is very likely that you will find one in half a year; If you connect your own miner to the mine pool, you can ensure that you have a basic income every day, which is relatively stable for miners. The premise is to select a suitable ore pool according to different currencies. Generally speaking, the current mining pools: ant mining pool, fish mining pool, coin printing mining pool, viabtc, flypool are all pretty good

3. 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.

4. It's one of the baskets with BTC;

5. The relationship between network speed and router is still very big
if your wireless network or network speed through router can not reach broadband speed, then it is likely that it is the problem of router
it is recommended to replace a better router or use al band router to get better service, WiFi language

6. According to the operation principle of the miner, the miner will continue to accept the tasks assigned by the mine pool, and return the calculation results to the mine pool. However, there is a delay in the communication between the mine machine and the mine pool network, and the invalid submission caused by the network delay is called the rejection rate.

7. The miner is used to dig money, and the mine pool is used to deposit money

8. The collective data bitcoin of mining machine can be made by computer. This is called mining machine. For example, if there are 1000 mining machines, they will eat 1000

10. Gold, of course! This is the natural currency and the wealth of preserving value, with physical gold as the final guarantee; Bitcoin is a virtual electronic currency, most sovereign countries do not recognize its legal status, because its main purpose is to decentralize and supervise, which is easy to become a disaster area of money laundering. In the field of investment speculation, when bitcoin is hot, it is more fierce than gold speculation. Provided by Liu Anyuan, an expert in stock analysis of Xinrong Street
