What are the principles of ether mining?

Like all blockchain technologies, Ethereum uses an incentive-based security model. Any node claiming to be a miner in the network can attempt to create and block validation zones. Many miners around the world are creating and validating blocks simultaneously. Each miner provides "proof" of the mathematical mechanism by sending blocks to the block chain. This test is like a guarantee: if this test exists, then this block must be valid.

For blocks to be added to the main chain, miners must provide this "test" faster than other miners. The confirmation process for each block is called a work test, through the "proof" of mathematical mechanisms provided by miners. It has been confirmed that miners in the new block will receive certain rewards. What is a reward? Ethereum uses an intrinsic digital token, ether, as a reward. Each time a miner tries a new block, a new Ethereum is generated and provided to the miner.

Ether coin mining process:

Ethereum's mining process is almost identical to Bitcoin's.

In mining, miners use a computer to guess the answer to a difficult problem repeatedly and quickly until a miner guesses the correct answer.

More specifically, the miner performs a hash function on the block header metadata (including the timestamp and software version) (the function yields a fixed-length string of letters and numbers), where the nonce value that affects the hash result is the only variable.

If Miner A is the first to find A hash that meets the requirements, then Miner A will be rewarded with ether and broadcast the block across the network for all nodes to verify and update the ledger. If Miner B finds the correct hash value, Miner A stops working on the current block and repeats the process on the next block.

In each Ethereum block, a seed is generated through the block header. This seed is called a seed, and the seed is only related to the current block. The seed generates a pseudo-random cache of 16MB.

Based on the cache described above, a 1GB DAG dataset is then regenerated. There is a dependency between the cache and the dataset. In general, the dataset depends on some element of the cache. In short, the element at the specified position in the dataset DAG can be computed whenever the cache is available. What the miner does is a process of randomly selecting elements in the dataset DAG and hashing them. Looking for a nonce-like model in Bitcoin. So compared to Bitcoin mining, Ethereum currently only requires the verifier to spend a certain amount of cache to verify that the hash of a given element is less than a certain hash value. The cache and dataset DAG are updated every 30, 000 blocks, so miners should focus on reading the dataset rather than changing it.
