Ethereum Cookbook

How it works...

In steps 1 through 5, we created a private Ethereum network. This should be enough for you to run a single-node network. With the minimum difficulty and maximum gas limit, this network is ideal for development and testing. At this point, your application can connect to the network with the default Ethereum port, 8545.

In steps 6 to 9, we are creating another peer and connecting it to the first node. This allows you to have a multi-node Ethereum network. All the blocks will be synced between these two nodes and will be accessible from both nodes. You can create and connect as many nodes as you want with the procedure explained here. Make sure to set appropriate firewall rules to ensure proper communication.
