Mining part1

1.

In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining

the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig

another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful

currency characteristics of bitcoin

1, decentralized

bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom

2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3, exclusive ownership

controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself

4, low transaction cost

bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution

5, no hidden cost

as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay

6, cross platform mining

users can explore the computing power of different hardware on many platforms

2. Bitcoin is the most popular virtual internet currency in the world. It can also buy a lot of things now. This kind of virtual currency can be obtained through the function of mining machine.? So how to get bitcoin? First of all, your computer should be installed with the latest version of bitcoin client. After opening the client, it will automatically download all the transaction information data on the network to the local. Depending on the network speed, this process may take several hours. At this time, your account balance is 0, you can ask your friends to send you some coins, but there are two more feasible ways: one is to do business, the other is to do mining. Many domestic users choose the second way, that is to do mining. More and more people are willing to work as miners themselves and let their computers proce bitcoin! It sounds tempting - just one computer can make money! The bitcoin g up by yourself as a miner can be converted into real RMB at bitcoin China trading platform! Now the threshold is higher than before. It's better to need professional computers. The difficulty of bitcoin mining is directly proportional to the amount of money that has been mined. The more difficult it is to mine, the more difficult it will be. After 20 million bitcoins are mined out in 2030, the remaining 1 million bitcoins will probably take decades to be mined out. At present, if the computer is on 24 hours, it will take about three months to dig a bitcoin.

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

4. In order to know what mining is calculating, we must first know the essence of bitcoin and its proction process. Bitcoin is a network-based electronic currency, which is actually a string of codes of the Internet, calculated by algorithms. Mining is the process of completing the algorithm and the only way to proce bitcoin. And because of the algorithm, there are only 21 million bitcoins
1. Mining can not only proce bitcoin, but also guarantee transaction information
similarly, a mathematical system contains 21 million mathematical problems, so we need to constantly seek the special solution of each mathematical problem through a huge amount of calculation. In addition, the special solution is unique
mining can not only increase the supply of bitcoin money, but also protect the security of bitcoin transactions and prevent fraulent transactions. In terms of process, bitcoin network is a point-to-point payment system, and anyone can trade through the transaction program
in order to ensure that the transaction process is truthfully recorded, the role of "miner" is required to be responsible for recording bitcoin transaction information. The time interval is 10 minutes. The best recorded transaction records among miners will be packaged and stored in a new block, and the corresponding miners will also receive a certain amount of bitcoin rewards
2. The mining process is extremely complex, which is beyond human power
the specific process is as follows. When a miner listens to the transaction, he will first verify the transaction information. The verified transactions will be recorded by miners and stored in their own database. There may be thousands of miners in the world doing the same thing, but every ten minutes, only one miner has the right to create a new block, so that the transaction information recorded by himself can be recognized and stored permanently
next, miners need to fight for the right to keep accounts. This is a competition of computing power. The core of this competition is to use computers to complete a large number of calculation tasks and find a super difficult random number. This random number is the special solution of the equation mentioned in the first paragraph. The miner who calculates the correct random number first wins. According to the rules of the game, the probability of a miner getting the accounting right is directly proportional to the proportion of his computing power in the total computing power of the whole network. In other words, the probability of finding the random number is equivalent to throwing out 100 million dice, and the total number of dice is less than 150 million. Therefore, mining requires a large number of computers, installation of specific algorithm software, repeated operation day and night, not human
3. Bitcoin mining is actually "villagers' bookkeeping"
maybe some netizens still don't understand, let's take an example. In a village, the villagers often borrow money from each other, even if they write a written document, there is a risk of default. Then, every time there is a loan behavior in the village, we will use the village trumpet to inform everyone that all the villagers (miners) will record all the transaction records in their own account books.

300, go to Outland and mine when you see mines, It's all money. It's... It's money in the blink of an eye

6. Wright coin mining cgminer reject rate is very good, the first miner 1%, the second 6.1% is expected to rise. The rejection rate of the second miner is too high. What is the reason? Does it have anything to do with settings? HD5870, - i19, - G2, the rest default, HW is 0, that is, the rejection rate is too high.

7. 1-75 copper mining, all novice areas have a lot of copper, 75-125 tin mining, tin mining is mainly concentrated in the 20-30 grade area, 125-175 iron mining, 175-225 silver mining. At this time, you can map. You can go to the wasteland of the eastern Kingdom and run around the map. If no one grabs with you, you can finish 225-300 silver mining in about two hours, In the current version of Angolo crater, there are a large number of silver ore occurrences. 300-325 is the best rising point area. There are two options: one is to go to Hellfire Peninsula to find magic iron, the other is to stay in Angolo to dig for silver until it doesn't rise. 325-375 is to dig for refined gold, and the other is to go to nagland. There are many ore occurrences, which can be completed soon, Notice that several ogre caves are ore concentration areas. 375-400 in Northrend's two novice pictures, north wind Tundra and Linfeng Fjord, dig cobalt ore. 400-450 the most convenient one is to dig saffron iron ore in icecap glacier or basin. When you reach 425, you can dig saffron iron ore until it is full. It's better to attach a mining + 5 to your gloves. In addition, there are rare ores: silver, gold, silver, silver, silver, silver, silver, silver, silver, silver, silver, silver, silver, gold, silver, silver, silver, silver, silver, silver, silver, silver, silver, gold Real gold, Hengjin can help you in a few critical points by melting up

8. Before mining, you should learn to mine, and then buy a miner's hoe to accompany you all your life
50 years ago, I practiced at the 5-10 level transfer station map of each race. ha-ha. Mineable copper
at 50, you can learn intermediate Sao. Now you can go to the 20-30 transfer station to study. It is recommended to study in (wetland) here, which is mainly in the cave beside the waterfall in the north of the map. After 125 years of training, I graated from the wetland. Copper, silver, iron and scorpion can be mined here
the place where you can enter LM BL now is thousand needle stone forest. This is a good place 125-175. If you are not happy here, you can beat me. Here you can mine copper, tin, iron, silver and gold
when you get to 175, you'll be happy now. You'll move to the wasteland immediately. I don't know why the mine is so big. You can ride your mount and run freely, but don't run to the top corner of the map. Want to kill NPC play can go to ha! You can pick (real silver) when you practice 230 here, but it's good to practice 245 here. The minerals that can be collected are iron ore, gold ore, silver ore, true silver and secret silver
now you can go to the scorching canyon. The black iron is waiting for you. If you don't go, he will cry. If you are tired of mining, you can go to the melting pot to watch the fire. But I believe you are sweating and don't want to leave the fire. You can practice 275 here. Congratulations when you get to 275. It's time for you to graate from mining school, Although I'm only 275, what's the matter? I can't mine any mine. It is mainly used to collect the iron ore from the true silver gold deposit in miyin and the black iron ore from the gold deposit
now you can go to East plague to realize your dream of becoming rich. Arcane crystal is watching you smile. If it's a thief, I'll go to xilishu and tear it. No one interferes with it, but I'm indifferent to it
according to this method, it's normal to go from 24 hours a day to 300 hours. It took me only 17 hours to get there. This is the mining time, not the whole time from 1 to 300,

9. Strictly speaking, we must dig for high configuration computers, but not for mobile phones and low configuration computers. That one has to run 24 hours a day. Now bitcoin has shrunk!

10. Hong Kong Zhongyuan group will acquire all businesses of Beijing Lianjia real estate
according to the financial channel of Phoenix Satellite TV, Hong Kong Zhongyuan group will acquire all businesses of Beijing Lianjia real estate. Zhongyuan Real estate is the largest real estate agent in Southeast Asia, which has a history of 30 years. Its founder, Mr. Shi Yongqing, was interviewed by Taiwan. Mr. Shi Yongqing said: the acquisition is an important part of Zhongyuan Real Estate's business in Beijing.
