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.

Selecting a good use case

Before we start any blockchain project, an important step is to select a good use case. We often see cases that can be solved through a distributed database or even a web application with good permission access.There is a puzzle to be cracked:

  • Is a business network involved?
  • Is there a transaction that needs validation or a consensus?
  • Are audit trails important, or origin control?
  • Immutability (data)
  • Finality (fewer disputes)

Make sure to draw a map with different organizations on, or a business network and how they are connected—this is a very important step. Moreover, check the use case addresses one or more attributes listed between the second and fifth points. If you don't have more than one of the attributes listed between the second and fifth points, then it probably does not fit with the blockchain solution.

It's a good idea to have a think tank or design thinking session when selecting a use case.
