The book clearly shows which industries are the most impacted by blockchain technologies and it provides several decision support tools to business executives. Managers in the most affected industries should no longer postpone the launch of blockchain-inspired initiatives, being those initiatives either large implementations or pilot tests aimed at growing the maturity level on this technology. Once decided to launch a project, other key options are related to what type of platform to implement, as well as on which consensus mechanism to rely on. The book provides a useful state-of-the-art to address these decisions. On the other side, managers working in the less impacted industries might look at blockchain as a unique opportunity for innovation, pointing their attention on some cross-industry applications.
