What does blockchain mining mean
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
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
for example, bitcoin was invented by Zhongben Cong in 2009, and the total number of bitcoin was only 21 million. By participating in the proction of blocks and providing proof of work (POW), we can get the reward of bitcoin network. Mining is the process of packaging and confirming the transactions in the bitcoin system over a period of time, and then recording them on the block

what is moving bricks
when it comes to "moving bricks", you will think of migrant workers or various online jokes, but today we only discuss "moving bricks" in the blockchain market
to describe "moving bricks" in vernacular is to make profits by using the price difference between different exchanges. The same currency has different prices in different markets. Buy it in a cheaper place and sell it in a more expensive place. The middle price difference is your profit
for example, the price of bitcoin BTC is $4000 on exchange a and $4100 on exchange B. after a buys BTC, it can be sold to B and each one can earn $100. This process is called "moving bricks"
Suppose you understand the blockchain. To put it simply, the blockchain generates a new block every ten minutes to store all the transaction information in the blockchain. This block is equivalent to a network account book, which correctly time stamps all the transactions of the whole network in the past ten minutes. The question is who will build it? The "miner" on the blockchain is to compete for the bookkeeping right of a block in the past ten minutes. The rule of competition is to solve the sha256 problem while correctly bookkeeping. Who can prove that his computer has the fastest computing power can compete for the legal bookkeeping right of the block in the past ten minutes. This is the "mining" process. In the bitcoin blockchain, miners who dig mines can get certain bitcoin rewards. Therefore, miner's more essential function is "bookkeeper"
in his bitcoin white paper, Nakamoto describes in detail the process of establishing the credit system:
Step 1: in order to make the whole network recognize effective, every transaction must be broadcast to each node (node: miner)
Step 2: each miner node should correctly stamp each transaction in the ten minutes and record it in that block
Step 3: each miner node should compete for the legal bookkeeping right of this 10 minute block by solving the sha256 problem, and strive for the reward of 25 bitcoins (50 bitcoins every 10 minutes in the first four years, decreasing by half every four years)
Step 4: if a miner node solves the ten minute sha256 problem, TA will publish all the time stamped transactions recorded in the ten minute block of TA to the whole network, which will be checked by other miner nodes in the whole network
Step 5: other miners in the whole network check the correctness of the block's accounting (because they are also stamping the time stamp for accounting, but they do not compete for the legal block's accounting right, so there is no reward). If there is no error, they will compete for the next block after the legal block, thus forming a single block chain of legal accounting, That is the general ledger of bitcoin payment system - blockchain
generally speaking, each transaction must go through six block confirmations, that is, six ten minute bookkeeping, before it can be recognized as a legal transaction on the blockchain. The following is the accounting format of bitcoin:
so the so-called "bitcoin" is such a billing system: it includes the owner using the private key to make an electronic signature and pay to the next owner, and then the "miners" of the whole network stamp the account to form a blockchain Network)

mining is a proct based on blockchain technology. Mining refers to the virtual currency launched by various companies, which is also called token. If the name is different, the miner is called miner
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.
to put it simply, blockchain is a new application mode integrating various computer technologies. Just treat it as a new technology. The network constructed by blockchain technology has the characteristics of "decentralization", "information tampering", "openness", "anonymity" and "security and reliability". These technologies can be applied in many fields, in short, it is very powerful ~
miner, a simple understanding is a more advanced computer, miner is to contribute to the blockchain network, you can regard miner as the guardian of blockchain
with mining machines, the blockchain network can operate normally. These mining machines are constantly doing calculations to provide computing power for the blockchain network. When the mining machine makes the correct calculation, the whole blockchain network will reward the mining machine with the corresponding digital currency. This process is called mining
if you also want to make a "contribution" to the blockchain, you need to download the mining system to start. Oh, let's have a look.
