While we were building a local private blockchain, we used a few command-line options such as --datadir, --identity, --verbosity, and so on. These options are also known as optional flags. They are Ethereum options and are useful for setting up a local blockchain and accessing testnets. Developer chain options support switching to developer mode. Other options are available for Ethash, transaction pools, performance tuning, account, API and consoles, networking, miner, gas price oracles, virtual machines, logging and debugging, metrics, stats, and options, and so on. Let's have a look at the following command:
$ geth help or $ geth h
The preceding command will give you a full host of Ethash options. Let's have a look at the format of the following command:
$ geth [options] command [command options] [arguments]
You can implement all...
