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.

About Packt


In this chapter, we developed a solution running on a real device that supports Node.js. We also used the low-level mraa library, which interacts with the device GPIO (General Purpose IO), reads analog sensors (temperature and soil moisture sensors) and uses digital pins to switch a relay on and off. This looks very simple but most devices have sensors and actuators, which may change the way in which they are used. However, they essentially follow the same concept.

We created a dashboard in the IBM Watson IoT Platform that is helpful for looking at what real-time data devices are publishing. We also created an application in the IBM Cloud Platform (Bluemix) and attached backing services (the IBM Watson IoT Platform organization) to the application in order to leverage configuration data to connect to the service and deploy the application using the Bluemix command-line interface.

The next chapters will introduce blockchain as a platform for interconnected businesses and explain its...
