Blockchain: Reinventing Business Systems by Dr. Andrew S. Nevin, PhD, offers an in-depth exploration of how blockchain technology is transforming traditional business models. Dr. Nevin, a Partner and Chief Economist at PwC Nigeria, is a prominent advocate for blockchain adoption, particularly in Africa. His work emphasizes blockchain's potential to enhance trust and efficiency by creating a single, shared version of the truth among parties. Key applications discussed include land registries, pharmaceutical supply chains, and corporate registries. Dr. Nevin's initiatives, such as co-founding Binkabi—a blockchain-enabled trading platform aimed at increasing incomes for farmers in developing countries—highlight practical implementations of the technology. This book serves as a valuable resource for understanding blockchain's impact on business systems and its role in fostering economic development.
