What does bitcoin mining cost mean
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
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.
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 system is composed of users (users control the wallet through the key), transactions (transactions will be broadcast to the whole bitcoin network) and miners (a blockchain is generated by competitive computing to reach a consensus at each node, and the blockchain is a distributed public authoritative account book, including all transactions in the bitcoin network)
mining is a process of increasing bitcoin money supply. Mining also protects the security of the bitcoin system, prevents fraulent transactions, and avoids "double payment", which means spending the same bitcoin multiple times. Miners offer algorithms for bitcoin networks in exchange for the opportunity to get bitcoin rewards. The miners verify each new transaction and record it in the general ledger. Every 10 minutes, a new block will be "mined", and each block contains all the transactions from the generation of the previous block to the present, which are added to the blockchain in turn. We call the transactions included in the block and added to the blockchain "confirmed" transactions. After the transaction is "confirmed", the new owner can spend the bitcoin he gets in the transaction
there are two types of rewards for miners in the process of Mining: the new currency reward for creating a new block, and the transaction fee for the transaction contained in the block. In order to get these rewards, miners compete to complete a mathematical problem based on encrypted hash algorithm, that is, to use bitcoin mining machine to calculate the hash algorithm. This requires strong computing power, how much the calculation process is, and whether the calculation results are good or bad. As the proof of miners' calculation workload, it is called "workload proof". The competition mechanism of the algorithm and the mechanism that the winner has the right to record transactions on the blockchain ensure the security of bitcoin
miners also get transaction fees. Each transaction may contain a transaction fee, which is the difference between the input and output of each transaction. A miner who successfully "digs" a new block in the process of mining can get all the transaction "tips" contained in the block. With the decrease of mining reward and the increase of the number of transactions in each block, the proportion of transaction fee in miners' income will graally increase. After 2140, all miners' earnings will be made up of transaction fees
mining is a process of decentralizing settlement, in which each settlement verifies and settles the processed transaction. Mining protects the security of bitcoin system, and achieves the consensus of the whole bitcoin network without a central organization. The invention of mining makes bitcoin very special. This decentralized security mechanism is the basis of point-to-point e-money. The reward and transaction fee for casting new coins are a kind of incentive mechanism, which can regulate miners' behavior and network security, and at the same time complete the currency issuance of bitcoin.
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 fact, the mining calculation of bitcoin is to do math problems together. The problem stem is the transaction that needs to be recorded. By doing the problem, everyone grabs the bookkeeping right, and the miners can get system rewards and transaction fees. The feature of sha256 algorithm used in bitcoin is that it is easy to verify the known answers correctly, but it is very troublesome to get the answers, and it needs to try one by one. The miner who got the answer first was recognized by everyone as having snatched the right to keep accounts, and the reward was given to him. Let's continue to grab the bookkeeping right of the next question. In short, the significance of these calculations is only to ensure the stability and safety of the whole system, and there is no more significance
it is not comprehensive to regard bitcoin as a by-proct of computing. The generation and issuance of bitcoin, all the transactions and circulation in the bitcoin chain, and the stability of the bitcoin system are the purpose of computing and are integrated. Of course, in addition to maintaining the system, it does not proce other value and procts. This is also a black spot where bitcoin is accused of not being environmentally friendly and wasting resources. In general, bitcoin, as a milestone blockchain digital currency, is e to the huge value of a large amount of computing power investment and user trust. There is no doubt about that
