Testing the transaction endpoints

Let's test the /transaction/broadcast and /transaction endpoints to make sure that they are both working together correctly.

For this test, the first thing that we need to do is connect all the nodes together to make a network. You might remember how to do this, as we learned about it in Chapter 4, Creating a Decentralized Blockchain Network. We'll run through the steps quickly anyway, to refresh your memory.

Recapping how to create the network

Take a look at the following steps to understand how to connect all the nodes:

1. Go to Postman and hit the /register-and-broadcast-node route. This can be done on any of your nodes. In our example, let's use localhost:3001.
2. Now, inside...
