Executive consultant Obreahny O’Brien gives the reader a point of view on blockchain technology based on her years of management consultancy experience. The book contains adaptations of presentations delivered to America’s top board rooms, including stakeholders’ responses and case studies at various phases of the blockchain implementation lifecycle. The aim of this book entitled, ‘Blockchain for CEOs: Three Presentations to America’s Top Boardrooms,’ is to democratize access to learning for both incumbent stakeholders looking to understand the technology, and blockchain entrepreneurs hoping to sell applications of the technology.
