In this chapter, we have learned about the basics of Hyperledger Fabric's. After setting up a development environment, we wrote a chaincode for an insurance claim use case. We then studied fabric composer configuration. Finally, we ran the end-to-end fabric test execution for our insurance claim application. We can see that it is quite complex to use Hyperledger Fabric to implement an insurance claim application. In the next chapter, we will learn how to use Hyperledger Composer to quickly write an insurance claim application.
