When did the mine come out

1. 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.

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

4. Making the world is a good game. In this game, players need to build their own houses. In the evening, dwarves will sleep, and in the day, they can also direct dwarves to do things. However, sometimes dwarves run around. How to solve this problem? Let's see the following players' experience<
mining and dwarven operation experience
1. Dwarves sleep
there are several conditions for dwarves to sleep,
A: closed house, B: hanging statue, C: one person, one bed, D: the position of the bed should not exceed the space planned by the statue,
A: closed house, the world structure in the game is two layers, one in front and one in back, as shown in the figure,

at the beginning of the game, only one layer of wall was built, so the statue was not closed (the ball on the top of the statue turned yellow). In addition, if the position on the picture was g out, it was considered that it could not be closed, so we should avoid this problem.

the problems of B and C are very simple, not to say much,
D: the position of the bed should not exceed the space planned by the statue.
after the statue is detected, flowing stars will appear on the boundary to show the boundary. The position of the bed should not exceed that boundary. Otherwise, it will not be under the protection of the statue, and the dwarves will not be able to sleep at ease. Finally, the dwarves will be ordered, Then choose "choose dwarves" -- "sleep" and go to sleep obediently.
possible problems:
1. Sometimes the space is closed, and the statue will not change color immediately. Wait a moment, and have a look. If you confirm that the space is OK, you can close the game and go in again.
2. When digging underground, remember that if a wall behind is broken through, Remember to repair immediately (the repair method is to put the soil or stone in the menu below, click the soil, and then point the place to be repaired. The same way is to transform the terrain). If you don't repair it immediately, you will be miserable. You need to fill the map to find a small hole!!!! It's terrible!!!! Remember, remember
2. About upgrading
I saw many friends say that goblin was destroyed at level 5 or 6, which was actually caused by the fact that the dwarves could not return blood without building a shelter before level 3
if the shelter was built before level 3, there would be no problem at all, so my suggestion is: develop underground
because of this, You just need to build a manhole cover (the door should be built after the manhole cover, but also the lock, which is very troublesome). You only need to leave an exit, and you can quickly complete the closed space, so that the dwarves can rest and recover their blood
3. About the running of dwarves
I saw a post before saying: the biggest enemy is not goblin, nor all kinds of monsters, and the biggest enemy is the intelligence of dwarves!!! Always like to stick in the monster pile, really can't hurt
the solution is that at level 2, there will be a sign with a little tortoise on it (coming out with the statue. If you look carefully, it's not a tortoise, it's a little green monster. Anyway, I first feel that it's a tortoise). Put that sign where dwarves always like to run around, so that they won't cross the sign to dangerous places.
4 About mining, collecting
at the beginning of the game, they all rely on dwarves to run around, mining, collecting, slow death!!! Later found that there is magic door this magical thing
it's the magic that appeared at the beginning (the mapping is very troublesome, so it's just described). The blue one has an oval shape in the middle, like an eye. There's a "2" in the lower right corner. This is the magic gate. The starting point of the magic gate is home by default. You only need to consume "2" magic points (at first you thought that the number 2, the logo can only be used twice, but later you know it's not!! Wipe!!! The blue gem with mana in the upper left corner can recover a little in 5 minutes, but if you upgrade, it will be fully recovered. You can also adjust the time of the computer and restart the game, You can open the door in the distance
is it an instant!! Is the instant speed doubled!!!!!! Yes, it's super fast, whether it's mining, or collecting wood, water, or berries.
the general way used by building owners is to cut down the trees in front of the door, transform the potholes into flat ground, and then find a waterside in the distance to transform a large area of land. Anyway, with the portal, there will be a forest farm. The advantage of waterside is that plants grow fast. Do you find that no matter how you refresh the map, the environment and resources will change, but what remains unchanged is a stone mountain at the end of the horizontal axis!! That's our quarry!!!! With the portal, everything has been solved!!!! Therefore, it is not a problem to accumulate resources rapidly in the early stage
there are also mining tips. When mining, first dig a vertical shaft from your hometown (then cut more trees and build more ladders. You can't climb slowly without a ladder, and you won't fall down). And then straight to the left and right sides of the excavation, this process will see a number of mines, in the place of ore ignition, marking, when necessary, directly open transmission to dig down!!! But note that there will be many ants in the hole below. Although the attack power is not high, once the hole is g, there will be a large number of ants. In the early stage, it's better not to try to provoke, at least wait for armor and iron sword to abuse them
5, But there will be some big tasks (that is, tasks with more words), such as fishing, such as using magic compass. When I played the magic compass several times before, I encountered the problem that the magic compass task got stuck, because the magic release has a distance limit. The task is to use magic compass to find the nearest secret room, However, the nearby secret rooms were discovered by me in the early stage of mining, which directly led to the failure of this task. When the card was closed, I had to reopen it, and then I went to the edge area to look for mineral deposits (anyway, there was a portal). After this magic synthesis, I had to release it once to create a tree before I could continue to develop. Then there would be another task, but you can find the secret room again, So the first time you put it, you don't have to look for it. Just put the magic. The second time, you can look for the secret room.

Mining is the use of bitcoin mining machine, which is used to earn bitcoin

one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, can surpass the single graphics card of most users

and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining

< H2 > extended data:

bitcoin mining process:

1. To find the ore pool

to start mining, there must be a ore pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm

2. Download bitcoin miner (software)

in fact, there are many kinds of this miner, you can go to the official website to download

3. Setting mining software is a green software. After installation, we can set the language first to facilitate further setting. Next, you need to set the server, user name, password, equipment and so on. Generally, the server chooses a better network from BTC guide series, and the user name and password are set by ourselves before

4, bitcoin mining start

when we confirm that all settings are correct, click the "start mining" button to start bitcoin mining, and then the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, you can monitor the state through gpu-z or graphics card driver

6. First of all, you need to understand the time point of bitcoin Mining:
a total of 2100W bitcoins are issued, and each block is generated for 10 minutes, and a block rewards a certain number of bitcoins. In the beginning, 50 bitcoins were awarded for each block of mining. In the future, the reward was halved for every 21000 blocks (about once every four years). Now, 12.5 bitcoins are awarded for each block generated. The generation time of each block is 10 minutes, but with the development of computer technology, now the mining calculation power is increasing, so the generation time of a block must be less than 10 minutes, which requires certain control measures to ensure this time. This measure is the difficulty of mining. If the output time of each block is less than 10 minutes, the difficulty of mining will be increased. If the output time is more than 10 minutes, the difficulty of mining will be reced. The difficulty adjustment time is 2016 blocks, that is, 2 weeks
after every 2016 blocks, all nodes will automatically adjust the mining difficulty according to a certain formula. This formula is obtained by comparing the latest time spent in 2016 blocks in this cycle with the expected time (20160 minutes, i.e. two weeks)
new difficulty = old difficulty * (time spent in the past 2016 blocks / 20160 minutes)

7. Eight kings "wine song": Du Kang old son brew God pot, pride and palatable, if you want to get rid of all kinds of diseases, add joy for you. Who is it? Namo, three water to a unitary, well-known as wine, hey. Du Kang's old son brewed a magic pot, which was full of pride and palatability. Without it, Li Bai and Du Fu's poems would be few. Who is it? Namo, three water to a unitary, three meals a day, nothing to ask for, but not a lack of wine every day, ah Hoo hey.

8. You're right.

9. The ore spot is fixed

the refresh is random. After each ore is mined, it will be refreshed at any ore spot. The refresh time is different. The snow field is very fast, which should be about 10 minutes, and other scenes are estimated to be 20-30 minutes

10. The brush is very slow. It refreshes every 10 minutes or so. Skill is not too good, I personally remember a few more fixed refresh point, each time the mine brush out, first pick these. After picking, you can stroll around the corner very leisurely, refresh time is almost, and then go to grab those fixed brush points.
