This command will be start the node in private network with id 1234. The flag --http is used to enable Web App Access, we will use this in next post to connect Metamask with that private network. The flag --allow-insecure-unlock is used to permit execute transfers without a web application, we will use this in tests to this network. The flag --nodiscover is used to prevent node from trying to connect to others automatically.

chainId: An integer greater than zero that defines a unique id for your private network. The main network has ID 1. If you supply your own custom network ID which is different than the main network, your nodes will not connect to other nodes and form a private network.. You can find a community-run registry of Ethereum networks at https://chainid.network.
