Project #3. Private Blockchain with GET and POST API Endpoints

I used express framework for creating the API.

To setup and start the project do the following:

1. Get the project.
2. Run command npm install to install the project dependencies.
3. Run command npm start in the root directory to start the project. You can also start it using node app.js.

How to use the API

1. To get a block using its height make a GET request to the following URL:
   http://localhost:8000/block/height
   where height in the above url is a positive integer.
2. To post a block with the a body payload make a POST request to the following URL:
   http://localhost:8000/block
   An example request looks like the following:

{
      "body": "Testing block with test string data"
}
