Simulating a network

In this section, we will extend our knowledge from single-node operations to multi-node setups. We’ll focus on setting up a private blockchain network using an authority set of private validators. Within this network, Substrate employs an authority consensus model, where a predefined list of authorized accounts, known as authorities, takes turns in a round-robin fashion to create blocks. This fundamental introduction will equip you with the skills to work with private blockchain networks and understand authority-based consensus mechanisms. Throughout this chapter, you will experience the practical functioning of the authority consensus model by utilizing two preconfigured accounts as the authorities responsible for block production. This simulated network will involve running the two nodes on a single computer, each with different accounts and keys. In the upcoming section, we will begin our journey by initiating a blockchain node using a predefined account...
