In this chapter, we explored an online cloud deployment of Hyperledger Composer through Composer Playground. By using the online network editor, we saw how to create definitions of the network, run tests on the network, and access the historian, where we were able to visualize all of the transactions that were run on the blockchain network.

We also ran the installation of a local development environment and gave you a resource to use to set up a production-level Hyperledger setup running on Kubernetes.

In the next chapter, we'll explore the main actors in the modern food chain and their current challenges. We'll then discuss how IoT and blockchain technology can help to solve these challenges.
