Hands-On IoT Solutions with Blockchain

By: Maximiliano Santos, Enio Moura

Overview of this book

Blockchain has been the hot topic of late thanks to cryptocurrencies. To make matters more interesting, the financial market is looking for ways to reduce operational costs and generate new business models, and this is where blockchain solutions come into the picture. In addition to this, with Internet of Things (IoT) trending and Arduino, Raspberry Pi, and other devices flooding the market, you can now create cheap devices even at home. Hands-On IoT Solutions with Blockchain starts with an overview of IoT concepts in the current business scenario. It then helps you develop your own device on the IBM Watson IoT platform and create your fi rst IoT solution using Watson and Intel Edison.Once you are familiar with IoT, you will learn about Blockchain technology and its use cases. You will also work with the Hyperledger framework and develop your own Blockchain network. As you progress through the chapters, you'll work with problem statements and learn how to design your solution architecture so that you can create your own integrated Blockchain and IoT solution. The next set of chapters will explain how to implement end-to-end Blockchain solutions with IoT using the IBM Cloud platform. By the end of this book, you will have mastered the convergence of IoT and Blockchain technology and exploited the best practices and drivers to develop a bulletproof integrated solution.

In this chapter, we learned how to create a business network using Hyperledger Composer and the Watson IoT Platform.

In the process of developing the solution, we were able to create a Hyperledger Composer project using Yeoman; define shared data structures; create assets, participants transactions, and access control lists; as well as create the first version of a network and upgrade it to a newer version.

We were also able to create a device that is responsible for reading temperatures from the hypothetical transport of a food box from a factory to a warehouse, and later, from the warehouse to a store, and added that information to the food box asset in the shared ledger of the blockchain network.

The consumer of that food box was also able to track the information related to that box from the very beginning of the production chain.

Even though Hyperledger Composer and Watson IoT development are quite simple, the solution that we've created addresses a huge problem regarding safety...
