In Chapter 3,  Explaining Blockchain Technology and Working with Hyperledger, we looked at various frameworks that come under the umbrella of the Hyperledger distribution ledger. We then analyzed one of these, Hyperledger Composer, a powerful tool for developing a blockchain network. 

In terms of blockchain, one of the biggest advantages of using Hyperledger Composer is the excellent documentation that comes with the framework, not just on the site itself, but also on the developer's website and other websites that hold examples of code and routines.

Here, we'll look at a step-by-step guide of a slightly less common use case than the one found on Hyperledger Composer's tutorial site, which will demonstrate how simple it's to create a blockchain network. We're going to use Hyperledger Composer's platform, which is called Playground.
