Summary
Design and implementation a well-functioning chaincode is a complex software engineering task which requires both the knowledge of the Fabric architecture, API functions and of GO language as well as the correct implementation of the business requirements.
In this chapter, we have learned step-by-step how to start a blockchain network in dev mode suitable for implementation and testing of the chaincode and how to use CLI to deploy and invoke chaincode. We have then learned how to implement the chaincode of our scenario. We explored the Init and Invoke functions through which Chaincode receives requests from clients, explored access control mechanism and the various APIs available to developer to implement chaincode functionality.
Finally, we learned how to test chaincode and how to integrate logging functionality into the code. To get ready for the next chapter, you should now stop your network using ./trade.sh down -d true.
