1. The token of Ethereum is proced in the process of mining, with a mining rate of 5 Ethereum coins per piece. The mining process of Ethereum is almost the same as that of bitcoin. For each transaction, miners can use the computer to run the unique title metadata of the block through hash function, and guess the answer repeatedly and quickly until one of them wins
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.

2. Ether, an ether. One of the oldest synthetic organic compounds. Colorless liquid, very volatile, special smell; Extremely flammable ether with high purity should not be stored in open for a long time, otherwise its vapor may lead to open fire in the distance and then cause fire. The anesthetic concentration of ether was 109.8-196.95 g / m3 (3.6% - 6.5%). 1-303 g / m3 (7% - 10%); When it exceeds 303 g / m3, it is dangerous to human life. Continuous inhalation of 6.06 g / m3 (2000 ppm) can cause dizziness in some people; Generally speaking, it's not poison, but it's a kind of dangerous chemical
3. Ether is an organic compound, molecular formula is c4h10o, is a colorless transparent liquid, has a special pungent smell. It's sweet. Very volatile. Its vapor is heavier than air. It can be oxidized to peroxides, aldehydes and acetic acids under the action of air. Exposure to light can promote their oxidation
1. It is stable and seldom reacts with other reagents except acid
2. It will slowly oxidize into peroxides in the air. The peroxides are unstable and easy to explode when heated. It should be stored away from light<
risk overview
the main function of this proct is general anesthesia. Acute mass exposure, early excitement, and then drowsiness, vomiting, pale, bradycardia, hypothermia and irregular breathing, and life-threatening. The temporary effects after acute contact include headache, irritability or depression, salivation, vomiting, loss of appetite and sweating. Liquid or high concentration vapor is irritating to eyes
chronic effects: long term low concentration inhalation, headache, dizziness, fatigue, drowsiness, proteinuria, polycythemia. Long term skin contact can cause dry and chapped skin
hazard characteristics: its vapor and air can form explosive mixture, which is easy to burn and explode in case of open fire and high heat. It can react strongly with oxidant. It can proce explosive peroxide after long time in air. In a fire, heated containers are dangerous to explode. Its vapor is heavier than air, it can spread to a considerable distance at a lower place, and it will catch fire and burn back in case of fire source
it is mainly used as excellent solvent for oil, dye, alkaloid, fat, natural resin, synthetic resin, nitrocellulose, hydrocarbon, linseed oil, petroleum resin, rosin resin, perfume, non vulcanized rubber, etc. Wool and cotton spinning instry is used as oil cleaning agent.
