From what we have learned in the preceding section, we know that our register-node route and that the register-nodes-bulk route are both working correctly. So, in this section, let's put it all together and test our register-and-broadcast-node route, which uses the both the register-node route and the register-nodes-bulk route.
The register-and-broadcast-node endpoint will allow us to build a decentralized blockchain network by allowing us to create a network and add new nodes to it. Let's jump right into our first example to get a better understanding of it. To understand how the register-and-broadcast-node route works, we'll make use of Postman.
In the Postman application, we want to make a post request to register and broadcast the node on localhost:3001. However, before we do that, just make sure that all four nodes are...
