8) Update spec.json file

1) Update spec.json on both MoC node and rpc bootnode.

• Stop Parity

sudo systemctl stop poa-parity

• Add Registrar contract address into params section of spec.json. Make sure it is the appropriate params section.

    "name": "...",
    "engine": {
      ...
    },
    "params": {
      ...,
      "NetworkID": "xxx",
      ...,
      "registrar": "0xREGISTRAR_ADDRESS"
    },
    ...

2) Restart Parity on both nodes.

sudo systemctl restart poa-parity && sleep 10 && sudo systemctl restart poa-netstats

3) Check Netstat to ensure your nodes are communicating. They should display the same block hash for each block.

Open http://1.2.3.4:3000 (using your Netstats url instance) to check your nodes.
