Cook up a blockchain demo app

It’s never been easier to see what benefit blockchain can bring to a business.  Using the Hyperledger blockchain service on IBM Bluemix, in a few simple steps it’s possible to deploy an app which shows the benefits of applying blockchain to a car leasing supply chain.  This short video gives an overview of the use case.

 oneSign up for an IBM Bluemix account

Click on this link, press the “Create a Free Account” button and follow the dialogue to access Bluemix.  If you already have a Bluemix account, log in instead!


When you have your Bluemix login credentials, proceed to step 2.

Click on this link to access the starter apps and tutorials catalogue.  Select the “Deploy to BlueMix Car Lease” button.


 It’s worth time exploring the rest of this page too, but here we will focus on the Car Lease demo.  The button will deploy the demo into your Bluemix account (you may have to log into your account too):


The deployment can take a few minutes, but once it’s done your screen will look like this – and press “VIEW YOUR APP” to progress to the next step.
