Before and after mining

1. 1. What does mining mean
ancient mining can be traced back to the selection of stone materials in the stone age. Later, with the rise of the metallurgical instry, mining, mineral processing technology has graally developed. This paper introces the ancient Chinese open-pit mining, underground mining, roadway support, rock fragmentation, roadway ventilation, lighting, drainage, transportation, mineral processing and other aspects< There are many surface outcrops, slope deposits or resial deposits in open-pit mining of various metal veins or orebodies, so open-pit mining has become an important mining method in ancient times. Open pit mining can be divided into excavation method and reclamation method
2. Mining is the synonym of accumulated income for activities in bitcoin

mining is brought out by the recent popularity of bitcoin. As a virtual currency, bitcoin can be exchanged for real currency. One of the ways to get bitcoin on the Internet is to participate in related activities every day. These activities, like mining in online games, need to slowly accumulate wealth in exchange for bitcoin.

2. If you are poisoned or your hardware is damaged, I advise you not to use your home computer to mine. My gtx780 is afraid to mine. If you set up an ordinary graphics card with a computing power of 200mh / s and a full load computing power of 150W, you will lose 1.49 yuan in 24 hours and 44.79 yuan in a month. If you add in the cost of a graphics card of thousands of yuan, it's even worse.

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.

Mining means that users download software from personal computers and then run specific algorithms to get corresponding bitcoin after communicating with remote servers

bitcoin is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods

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

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

extended materials:

the founder of bitcoin:

on November 1, 2008, a person who called himself Satoshi Nakamoto posted a research statement on a secret cryptography review group, stating his new idea of e-money - bitcoin came out and the first transaction of bitcoin was completed

bitcoin has got rid of the constraints of third-party organizations with the help of Internet, which Nakamoto calls "regional chain". Users are willing to dedicate the computing power of CPU and run a special software to be a "digger", which will form a network to maintain the "regional chain". In the process, they also generate new money

trading is also extended on this network. The computer running this software can solve the problem of irreversible code, which contains several trading data

the first "miner" to deal with the problem will be rewarded with 50 bitcoin, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes

in 2009, Nakamoto designed a digital currency, namely bitcoin. The booming bitcoin market has gone up and down, and the identity of its founder "Nakamoto" has always been a mystery. Rumors about "the father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura

5. Bitcoin wallets are not registered. You only need to download one. However, the synchronization of the wallets will be very slow, and the wallets will take up more than 15GB of space. Therefore, if the amount is not large, it is easier to have a trading platform

6. It's about bitcoin and lettercoin, right
let's put it this way, there are two types of people who can make money. The first category is people who use mining machines, which are dedicated mining hardware. The second type is not professional mining, but it uses public electricity charges
mining machine, with high investment, is similar to investment. Public electricity, 2K graphics card is about 500-700 a month
in addition, you need to use a card to dig bitcoin, and N card is not worth electricity. Now it seems that you can use n card to dig Wright's coin

7. Six years ago: at the lowest level, the iron ore was directly turned into ingots. After that, the furnace was added to make iron. After that, the vertical distribution of minerals was clearly defined. That is to say, there was no landmark diamond. After tat, ruby was added, but unfortunately it was changed to the current emerald, just because of Jeb_ It is a red and green color blindness

followed by 1.8, adding diorite, granite and andesite

after that, with the emergence of custom mode, ore world is no longer a dream
...
minecraft never stops moving forward

8. It's the second one. According to the previous block information, root node information, real-time mining time, difficulty and random value, the random string is generated by twice hash256 algorithm calculation, and is allocated and recorded when the verification is passed.

9. Generally speaking, you decide according to the monster level and task level of the current map. The higher the task level is, the higher the mining skills are needed. Therefore, the early stage of mining is in the map of the first task you graate from your birthplace. Then, mine according to this
