Hands-On IoT Solutions with Blockchain

By: 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.

The technological approach 

Now that we have a better understanding of our process and potential problems, let's see how technology can be useful to us. Here's a representation of a standard blockchain Hyperledger Fabric architecture:

The preceding diagram shows us three important layers: frontend applications (on the left), API/SDK (in the center), and Hyperledger Fabric and the IoT platforms (on the right). 

Let's review each layer in more detail.

Frontend applications

This layer is responsible for data input and can be a packet, such as one from SAP, Salesforce, or Siebel, or a custom application. It can also interact with IoT devices, collecting data and registering in the blockchain...
