Private Blockchain Application

Run the application with the following command from the root directory:

node app.js

Be sure you run npm install before trying to run the application.

Notes

1. The route submitstar was renamed to submitStar for consistency.

2. The existing routes for getting a block by height/hash were functionally identical (GET /block/:height vs GET /block/:hash). This resulted in the first defined route overriding the second, meaning that the code for GET /block/:hash was never reached.

   To resolve this, I renamed the route to get blocks by hash to be /block/hash/:hash.
