many new users believe that the sole purpose of mining is to generate ether in a way that does not require a central issuer (see our guide "what is ether?"). It's true. The token of Ethereum is proced in the process of mining, with a mining rate of 5 Ethereum coins per piece. But mining is at least as important. Usually, banks are responsible for keeping accurate records of transactions. They make sure that money is not created out of thin air and that users don't cheat and spend money many times. However, blockchain introces a new way to keep records, the whole network instead of intermediary, to verify transactions and add them to the public ledger
Ethereum mining
although "no trust" or "trust minimization" monetary system is the goal, there are still people who need to ensure the security of financial records and ensure that no one cheats. Mining is one of the innovations that makes decentralized records possible. Miners have reached a consensus on the history of transactions in terms of preventing fraud (especially double spending on ether) - an interesting issue that hasn't been addressed before the decentralized currency works on the blockchain. While Ethereum is looking at other ways to reach a consensus on the effectiveness of the deal, mining currently keeps the platform together
how mining works
today, the mining process of Ethereum is almost the same as that of bitcoin. For each transaction, the miner can use the computer to guess the answer repeatedly and quickly until one of them wins. More specifically, the miner will run the unique header metadata (including time stamp and software version) of the block through the hash function (which will return a fixed length, unordered string of numbers and letters, which appears to be random), changing only the 'nonce value', which will affect the hash value of the result
if the miner finds a hash that matches the current target, the miner will be granted ether and broadcast the block across the network for each node to verify and add to their own ledger . If miner B finds the hash, miner a stops working on the current block and repeats the process for the next block. It's hard for miners to cheat in this game. There is no way to fake the work and come up with the right answer to the puzzle. That's why solving puzzles is called "proof of work."
on the other hand, others have little time to verify whether the hash value is correct, which is exactly what each node does. About every 12-15 seconds, a miner finds a stone. If the miner starts to solve the puzzle faster or slower than this, the algorithm will automatically re adjust the difficulty of the problem so that the miner can rebound to about 12 seconds of solution time
miners earn these ethers randomly, and their profitability depends on their luck and the computing power they put in. The specific workload verification algorithm used by Ethereum is called "ethash", which aims to require more memory, making it difficult to mine with expensive ASIC. Special mining chips are now the only profitable way to mine bitcoin
in a sense, ethash may have achieved this goal successfully, because dedicated ASIC is not available for Ethereum (at least not yet). In addition, as Ethereum aims to shift from proof of work mining to "proof of equity" (which we will discuss below), buying ASIC may not be a wise choice because it may not prove useful for a long time< However, Ethereum may never need miners. Developers plan to abandon proof of work, the algorithm currently used by the network to determine which transactions are valid and protect them from tampering to support proof of equity, which is guaranteed by token owners. If and when the algorithm is launched, proof of equity can become a means to achieve distributed consensus, and the consensus uses less resources.
Ethereum miner fee
1. In a public chain, anyone can read and write data. Reading data is free, but writing data to the public chain costs a certain amount of money, which helps to prevent junk content and protect its security through payment
Secondly, any node on the network (each connected device containing a of the account book is called a node) can participate in the mining method to protect the network. As mining requires computing power and electricity charges, miners need to be paid for their services, which is also the origin of miners' fees Third, the difference between Ethereum and bitcoin, Ethereum introces the concept of gas, the purpose of which is to limit the amount of work required to execute the transaction and pay for the execution. Gas is used to measure the resources (including computation, storage, bandwidth, etc.) consumed by your transaction (or contract code call)

ten rights of miners:
1. The "ten rights" of coal mining enterprise workers in safe proction include: the shift leader does not go down the well, and the workers have the right not to go down the well; The workers have the right to leave the well early if the shift leader leaves the well early; Workers have the right not to work if potential safety hazards are not investigated; If the management personnel command against rules and regulations, the workers have the right not to carry out them
Without safety measures, workers have the right not to start work; Workers have the right not to go down the well if they don't organize safety study before class; If the "Trinity" (monitor, safety inspector and gas inspector) safety inspection is not carried out, workers have the right not to start work The workers have the right not to start the work if the detection and monitoring system is not installed in place and operates abnormally; Workers have the right not to go down the well if they are not equipped with fully qualified labor protection and protective equipment; The route to avoid disaster is not marked, and workers have the right not to go down the well. The coal mine shall not dect the wages and dismiss the workers for the above reasonsIt depends on the electricity bill, and the efficiency of mining
the most efficient is Claymore on GitHub. The algorithm is very good, but the author has 2%
because of the wall, the download of GitHub will often have problems
< P > I modified the code to remove the author's extraction. Students who want to mine can try Claymore, Give a link to the network disk ~ students who are inconvenient in GitHub can download it from the network disk, double-click the EXE file ~ but remember to change the account to your own ~network cloud link - Claymore algorithm optimization version
hope to adopt
