Introduction to Mining
The term mining is derived from the analogy between cryptocurrency and gold. Gold or precious metals are rare, and electronic tokens are also the only way to increase the total is to dig mine. So is Ethereum, and the only way to release it is to dig mine. But unlike other examples, mining is also a way to protect the network by creating, validating, distributing, and propagating chunks in the blockchain.

If you want a complete explanation of the field, look at the solution to the stack overflow. The difficulty in this case is very low, because you do not want to wait a long time on the test network, chunks can be dug out, and then the value of Gaslimit is high enough to allow a node in the chunk to do the work to handle each transaction.
