In the blockchain, mining is the process of adding block to the chain, and afterwards, “miners” will receive the newly created coins. The nodes in the network will create valid “hashes” to secure each block in the blockchain. A hash is a long string of numbers that is generated through a cryptographic process based on the unique file size of each block - proving that the block is valid and has never been modified or hacked. This cryptographic process is called “Proof of Work”. The essential concept is it could be used to validate that the data has not been modified.
