Thanks to my family, who have always been patient with me as I explore new projects and paths, as in writing this book. Thanks to the identity and blockchain community that helped me discover and learn about many aspects of my true self and where the world might be going with decentralized technologies.

—A.P.

To the love of my life, who has been waiting 33 years since we were married—and 22 years since I went down the digital identity rabbit hole—just to see the one simple thing I promised her—getting rid of those &^%$# passwords!

To my two sons: this is a path to a better world that I’ve been beating since you were born. I hope you both are able to trod upon it all of your days—and the days of your children’s children’s children.
