Initialize the blockchain

Create new folder as working directory

mkdir -p $WORKING_DIR/$NODE_ROLE

Create new genesis.json file

Display the value of $MINING_WALLET_ADDRESS in Linux terminal

echo $MINING_WALLET_ADDRESS

  $CONTAINER_IMAGE attach \
  --exec "eth.getBalance('xxxxxxxxxxxxxxxxxxxxxxxx')"

please replace xxxxxxxxxxxxxxxx string with your mining wallet.
