 The multi-node command not only initializes these nodes but also gives you control over starting, stopping individual nodes. This level of control ensures you can test and iterate rapidly without needing to reinitialize the entire network each time a change is made. This makes it ideal for experimenting with validator behavior, network dynamics, and the impact of various configurations.
