Handbook of Blockchain, Digital Finance, and Inclusion: Blockchain, Artificial Intelligence, Mobile Security, and Regulation, Second Edition, Volume Three presents the latest technological developments and innovations occurring in financial institutions and the engineering advances driving them. Students, scholars, and professionals can explore practical and academic contributions in domains not usually found together in a single resource. Newly expanded into three volumes, this handbook not only emphasizes the financial opportunities made possible by digital banking, such as financial inclusion and impact investing, but it also presents the engineering theories and advances that can create additional opportunities. It provides a collection of contributions by pioneers, academics, and practitioners carefully chosen as established experts in their respective fields. Each chapter reviews, synthesizes, and analyzes the topic at hand, acknowledges areas where there are gaps between theory and practice, and suggests directions for future research when appropriate. The volumes are reorganized into distinct themes, every existing chapter is updated with the latest information, and new chapters bring even more valuable information to readers.
