What does Jingdong mining call back mining
mining: that is, bitcoin mining, is a process of using computer hardware to calculate the location of bitcoin and obtain it
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.
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
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
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
Bitcoin mining is a process of using computer hardware to calculate transaction confirmation and improve security. Bitcoin is a reward for miners to calculate and confirm
bitcoin also has a hype mode. Similar to bitcoin, there are also flow ores. Flow ores also have ways of trading and speculation, but the mining principle of flow ores is different from bitcoin. Flow ores mainly collect the idle bandwidth of miners and give them rewards
in fact, the blockchain technology adopted by bitcoin is more valuable than itself. This is a new way of information storage. The data is stored in all devices connected to the network. When new devices join, the information will be updated automatically, and all devices have the right to read the information
to understand the significance of bitcoin from the perspective of currency, we need to understand the currency itself first, and then compare it with the characteristics of bitcoin. After comparison, I think that bitcoin is a very high-quality currency, but some people don't think it is. They mainly question the formation mechanism of bitcoin and the lack of national credit as guarantee. They think its foundation is relatively weak
at present, there are quite a lot of arguments about bitcoin in academic circles. For example, if the total amount of bitcoin is certain, then whether it will cause deflation or inflation has different views. I think it's deflation, and the value of bitcoin will be higher and higher
at present, bitcoin still means a little bit of a safe haven currency. When the news of brexit came out, the transaction price of bitcoin rose by 20% - 30% to about 4500 yuan / piece
the biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. 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 21 million
the concept of bitcoin was first proposed by Nakamoto in 2009. Bitcoin, also known as bitcoin, is an open source software designed and released according to the idea of Nakamoto Tsung, and a P2P network built on it. Unlike most currencies, bitcoin does not rely on a specific central issuing institution. It uses distributed databases throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation
. The bitcoin system ensures that bitcoin will not be g out too quickly by adjusting the difficulty coefficient. Every 10 minutes, the whole network is absent from work to jointly calculate a difficult problem, compete for bookkeeping rights and bitcoin rewards. If the computing power of the whole network continues to grow, bitcoin will be g out soon. In order to ensure that bitcoin can be g out in about 10 minutes, Nakamoto designs the difficulty of mining for bitcoin, Every 2016 blocks (about 2 weeks) are dynamically adjusted, so that the difficulty after adjustment makes the expected time for each block to be generated 10 minutes. Now the difficulty coefficient is about 480ph / S (Note: September 2017), which is about 68 billion times that of Genesis block. In other words, with the current computing power, the miners in the whole network need to go through about 300 trillion hash operations to find a qualified answer, Generate a new block
. Compared with point-to-point trading, mining and other purchases on the trading platform are the most popular ways to obtain blockchain assets, that is, floor trading. Floor trading of blockchain assets is similar to stock trading. The platform can help you match up, and you don't need to know who your trading partner is. Your trading partner may be one person or many people, Whether it's buying or selling, the trading platform will record the hanging order price of everyone. The buyer and the seller can obtain the latest transaction price through the real-time order. At the same time, the trading platform will summarize the historical transaction price and volume into a K-line chart, which is convenient for investors to analyze the market trend. For example, the UTOR market is the mainstream trading platform in the world.
