Blockchain technologies are transformational: they can enable enterprises to reinvent processes and business models, and pursue radically disruptive use cases. Many decision-makers and IT professionals don't understand blockchain others confuse it with cryptocurrencies like bitcoin. This concise, accessible handbook brings clarity and pragmatism to blockchain technologies and opportunities. Written from a business perspective by three of IBM's leading consultants, it presents real-world examples that demonstrate what blockchain can and can't do. Drawing on their unsurpassed experience, the authors survey the technology's current state, introduce industry-specific and cross-industry use cases, review approaches to implementation and governance, and preview emerging capabilities all with a relentless focus on real business outcomes, and no hype.
