We will primarily concentrate on the Blockchain. It is the most important component of the three, as it is the back-end data persistence layer, i.e., “the truth”, while IoT and AI provide convenience and learned machine intelligence for front-end requests. Moreover, the Blockchain development tools have matured in the past year and developers want to know how these tools work. We'll start with a discussion of each technology providing introductory material. We will provide the reader with details around the players (e.g., Google, Ethereum, IBM, Microsoft, Amazon, etc.) who are fostering and developing standards for 'Power of 3” implementation. We will discuss the requirements not only technical but also for business and legal compliance with emerging regulation, security and privacy law. We will walk the reader through the steps required to create sample applications and code. This will facilitate, enable and accelerate the readers journey to the implementation of these new technologies. We will additionally explore emerging use cases for applications which integrate combinations of these technologies and most importantly how these technologies will change the way software development is conducted using the power of 3.
