 Before launching the `hydra-node`, it's crucial to establish and communicate each participant's network connectivity details. This includes the IP addresses and ports where `Alice` and `Bob's` nodes will be reachable for layer 2 network interactions. For this tutorial, we're using placeholder IP addresses and ports which should be replaced with your actual network details:

 - IP addresses and the port on which their `hydra-node` will run
 - A Hydra verification key to identify them in the head
 - A Cardano verification key to identify them on the blockchain

 ## Step 5. Use the Hydra head
 
 In this step, we'll demonstrate a basic transaction between `alice` and `bob` using the Hydra head. Hydra Head operates as an isomorphic protocol, meaning that functionalities available on the Cardano layer 1 network are also available on the layer 2 network. This compatibility allows us to use familiar tools like `cardano-cli` for transaction creation within the head.
 
 In this example, we will transfer 10 ada from Alice to Bob. Adjust the transaction amount based on the balances previously committed to the head.
