In this chapter, we introduced the business use case that our follow-on chapters will leverage to create a context around the code we will write. We have also deployed our first Hyperledger Fabric network and have now transitioned from theory to practice. Well done!

The next chapters will take you through the development of a blockchain application from two perspectives: (1) Foundation API using chaincode and the Fabric SDK (2) Business network implementation using Hyperledger Composer.

Through these two perspectives, we hope to give you an understanding of the flexibility of the solution and the ability to leverage each tool in the right context. To get ready for the next chapter, you should now stop your network using ./trade.sh down.
