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.

Creating the IoT part of the solution

After defining the entire blockchain network and getting everything up and running, we will now set up and develop the device that's going to update the ledger with box and pallet measurements.

To complete that, we're going to create a new device, using the same approach as Chapter 2, Creating Your First IoT Solution, and create an application that receives events from measurements and updates the blockchain ledger using the API that was exposed by the Composer REST server.

Hardware setup

To assemble this monitoring device, we will apply a couple of assumptions that might be pertinent to a production environment:

  • The transporting vehicle has a Wi-Fi connection available so that the device can connect to the internet
  • The monitoring device time is synchronized with the application time, including the time zone
  • All boxes are transported at the same time, using the same vehicle, so that the same conditions and measurements apply to all boxes in a pallet

In a production...
