Ethereum mining trusteeship

1.

Miner components include CPU, GPU, motherboard and hard disk, similar to a high configuration computer with a hard disk. Self assembly mainly depends on which aspect of hardware performance you want to highlight

mining machine has computing power, display card mining machine and storage mining machine. Daotong storage has long been concerned about the dynamic and hardware supply of mining machine, and its own components will be cheaper than those of the manufacturer< br />

2. At present, defi liquidity mining is the hottest, so you can use Eth and give it to the exchange for investment. It mainly depends on whether the exchange you choose has enough weight. If you choose the mining service of currency, as one of the four major exchanges, I think it is very important. Then the threshold of its procts is low. I think it is the best mining method at present.

3. At present, most of the mainstream Ethereum mining machines in the market come from bitmainland and Jianan Yun. However, with the decline of Ethereum's price, the profits brought by mining have been very meager. Investors can choose to invest in Ethereum on the digital currency exchange. At present, the mainstream digital currency transactions in the market are all coin security, fire coin network, bitnet, etc.

4. 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.

5. Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized Ethernet virtual machine to process point-to-point contract through its special cryptocurrency eth. At present, the mining of eth is mainly through the graphics card miner. The so-called graphics card miner is actually similar to the home desktop, but each machine has 6-10 graphics cards and no display

as for the mined mines, the trading platforms can be traded on any platform. The most important thing is to see how you trade. Do you want spot trading or futures trading, because the main procts of each platform are different. If you really can't find a platform, you can try the coinplus platform. It provides a variety of transaction types, and can quickly match orders. It's very convenient to buy and sell. The key is that the service charge is still low.

6. This is virtual currency. It's too risky. You'd better not play it
