Hyperledger Composer is a high-level toolset and framework that was made to quickly build and run applications on top of a Hyperledger Fabric blockchain.

We learned about Hyperledger Fabric in the previous chapter, so you already know that developing a Fabric-based application is quite complex as it needs to handle many configurations at the network level.

In this chapter, we will discuss the following topics:

• Hyperledger Composer—a quick overview
• Setting up a Hyperledger Composer environment
• Analyzing business scenarios
• The business network archive
• Implementing business transaction functions
