What's the meaning of stealing electricity to dig bitcoin
bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it
mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash
and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on
extended data:
mining risk:
1, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
2, system risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
Bitcoin is the first distributed virtual currency
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
extended information:
as a virtual commodity, bitcoin itself has no national boundaries, and its operation mode is a "decentralized" monetary system, which is very convenient for one-time large transaction. Bitcoin is traded through the network, and the owner's identity is only in the form of a set of encrypted computer code
in the operation, input a digital address directly, click the mouse a few times, and wait for the confirmation of the transaction to complete the transaction. The network can only record which address a bitcoin was g up from and how it was transferred
however, the identity of the owners of these addresses can not be verified, which is just like when money goes to an ownerless bank account, the relevant transactions can easily be invisible from the perspective of government supervision, and it is difficult to be tracked or intercepted. In addition, bitcoin can evade the scrutiny of exchange control institutions required by normal cross-border remittance, and the transaction records will not be recorded by banks and other parties
naturally, the problem of reporting to relevant departments after the transaction exceeds a certain amount is avoided. Buy bitcoin with domestic currency, sell it on foreign trading platforms, and withdraw it in US dollars. Asset transfer can be completed in a few minutes
it is not difficult to open an overseas bank account related to bitcoin for foreign exchange, and the conversion is very convenient. Because of these characteristics, bitcoin has been chosen by criminal organizations
Bitcoin is actually a virtual currency. When bitcoin first appeared, if you want to get bitcoin, you have to get bitcoin through mining. Therefore, bitcoin mining appeared. But bitcoin mining is more and more difficult, so it is very difficult to get bitcoin now
so now many people use Haru miner digs Ethereum, Monroe and other virtual coins. Most importantly, BTC can be directly equivalent in the end
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

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
previously, graphics cards were sold out because of the strong purchase of gold miners. The algorithm design of bitcoin is more and more difficult to dig. Therefore, the investment to dig the same bitcoin now is many times higher than a few years ago. Since the "mining" incident in Daqing Oilfield was exposed, the local police have counted the number. The average electricity cost of the mining machine seized is close to 500000 yuan in one month, and if it steals electricity, it is equivalent to making 500000 yuan in vain.
Mining bitcoin is also called mining. Starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
in the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods

shortcomings
first, the vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
Second, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed Thirdly, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading Fourthly, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthlessComputer mining is a bitcoin mining machine, which is a computer used to earn bitcoin
this kind of computer generally has professional mining chips, and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
the professional point is that mining is a distributed consensus system that includes the transaction data to be confirmed into the block chain, so as to complete the confirmation of these transactions. By mining, the data in the block chain can be stored in chronological order, the neutrality of bitcoin network can be maintained, and different computers on the bitcoin network are allowed to agree on the system state. To be confirmed, a transaction must be packaged into a block that complies with very strict cryptographic rules and verified through bitcoin network. These rules can prevent the modification of existing blocks, because once there is a change, all blocks will be invalid. Mining is as difficult as winning the lottery. No one can easily and continuously add new blocks to the block chain. Therefore, no one can control what content is included in the block chain or replace part of the content in the block chain to rece their cost
at present, bitcoin mining needs professional ASIC mining machines. For example, Avalon mining machine (commonly known as pumpkin Zhang mining machine), which has created countless number one mining machines in the instry, is said to be coming out soon, 28nm chips will be streamed soon, and 16nm chips are under development.
in the notice of the people's Bank of China
Ministry of instry and information technology
