With a correct understanding of the project objectives that were presented in the previous chapter, it's time to get the solution to work. In this chapter, I will guide you through creating a blockchain network using Hyperledger Composer.

In this chapter, we will cover the following topics:

• Creating a blockchain network
• Defining assets, participants, transactions, and access control lists using Hyperledger Composer
• Publishing the network to a Hyperledger environment

We will also borrow code from Chapter 2, Creating Your First IoT Solution, to create a device that will monitor shipments and interact with the blockchain network.
