Testing our block explorer

In this section, we're going to test the block explorer to make sure that it works correctly, and also to make sure that all endpoints and methods that we created in the previous chapter also work correctly. If the block explorer works, then we already know that the entire blockchain is also working correctly and is running on the decentralized blockchain network, so everything is wrapping up nicely now as we enter the final section of this chapter. Consequently, this is the last test that we will be doing. Let's follow these steps now to test the block explorer:

1. In order to test the block explorer, we should ensure that we have all five of the nodes running.
2. Next, head over to the browser and open up the block explorer by going to localhost:3003/block-explorer. You can actually go to a block explorer that's hosted on any of the nodes...
