How to do it...

1. Create a directory to save your blockchain data:

$ mkdir datadir

2. Create an account and save it to the directory:

$ geth account new --datadir datadir

You will be asked to enter a password for the account. An address will be displayed once the account is created. The key file for this account will be stored in the /datadir/keystore/ location.

3. Create a genesis.json file with the following contents:

{     "config": {         "chainId": 1100,         "homesteadBlock": 0,         "eip155Block": 0,         "eip158Block": 0,         "byzantiumBlock": 0     },     "difficulty": "400",     "gasLimit": "2000000",     "alloc": {         "87db8fceb028cd4ded9d03f49b89124a1589cab0": {             "balance": "100000000000000000000000"         }     } }
