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.

IBM Watson IoT Platform features

The IBM Watson IoT Platform is a hub for connecting devices, gateways, and applications for IoT solutions. It supports REST and MQTT protocols for applications, devices, gateways, event processing, and administrative tasks. The IBM Watson IoT Platform is available on the IBM Cloud platform (formerly IBM Bluemix), a cloud platform based on Cloud Foundry and Kubernetes.

Let's review the pertinent features of this platform.


In this section, we will discuss the following main features of the IBM Watson IoT Platform:

  • Dashboard
  • Devices, gateways, and applications,
  • Security

Let's begin!


This is the first thing that you will see when you access the IBM Watson IoT Platform. This dashboard can be a combination a number of boards and cards, offering several visualization options for your IoT solution:

Devices, gateways, and applications

Another feature available in the platform is device management control. This feature makes it possible to create and remove devices, gateways, applications, and device types. It also makes it possible to check and trigger actions to the device, such as a firmware upgrade request or reset:

You can also create API keys so that your applications can connect to the IoT organization and interact with the other components of the solution.


You can also manage the security aspects of a solution using the IoT Platform. This might include creating policies for device connections, white and black lists for the device's IP address, or looking at a country's rules. You can also manage users that are permitted or blocked from managing the IoT organization for solutions.
