This book is partially based on the courses we taught at the McCombs School of Business at The University of Texas at Austin, the School of Professional Studies at Columbia University, and the Smith School of Business at The University of Maryland in College Park.

We would not be writing this book if Prof. Prabhudev Konana, Prof. Sriram Vishwanath, and Dr. Caryn Conley did not work extremely hard to get our course approved at the University of Texas at Austin. Prof. Arthur Langer was instrumental in getting the course approved at Columbia University, enabling us to expand the content to technology management professionals. Prabhudev Konana and Prof. Pallassana Kannan gave us the opportunity to further refine our content to reach business executives by allowing us to create an executive education offering at the University of Maryland.

Sriram Vishwanath, Dr. Karl Kreder, Mr. Vijay Rathna, and Prof. Anand Anandalingam have co-taught this course with us at different times and our learnings from them are reflected in this book.

This book has benefited from the excellent work of the creative, knowledgeable, and hardworking teaching assistants across all the courses. These teaching assistants have included Alan Orwick, Yihe Liu, Parikshit Hegde, Cody Morton, Joseph Dowdall, Shubhangkar Jain, Roque Martinez, Ajay Nyamati, Denzell Ford, and Nicholas Khami. Shubhangkar spent a lot of time helping us with the quiz questions for Part 1.

We have also benefited from innovative instructional design support from Matthew Vaughan, Jennifer Hoeritz, and Joshua Shannon-Chastain. Several of the diagrams in this book are easy on the eyes due to the graphical design expertise provided by Nicholas Bonneau and Dr. Shohreh Anand.

We also want to thank industry experts who provided helpful academia-industry connections to enable our teaching to be up to date with cutting edge blockchain technologies. Ron Resnick has been instrumental in pioneering token taxonomy concepts which we mentioned in the tokenization chapter. Conor Svensson has provided good discussions on Enterprise Ethereum Architecture which we discussed in Chapter 6; Jack Lu, Peter Robinson, Chaals Nevile, and Dan Reecer have provided their insight on crosschain technology which we believe will connect both public and enterprise blockchains. We also want to thank Dr. Dan Burnett, Ken Fromm, James Harsh, Brittany Mauck for organizing numerous blockchain seminars and conferences which sharpened our knowledge on blockchains and blockchain education.

We believe that writing blockchain educational books are tedious tasks that cannot be accomplished without unconditional support from our families. We appreciate their forbearance, continued support, and love.
