Paperback edition updated with a foreword and new chapter on recent developments with cryptocurrency. Blockchain is the ingeniously simple technology behind Bitcoin. But it is much more than that. It is a public ledger to which everyone has access, but which no single person controls. It enables companies and individuals to collaborate with an unprecedented degree of trust and transparency. It is cryptographically secure, but fundamentally open. And soon it will be everywhere. In Blockchain Revolution, Don and Alex Tapscott reveal how this game-changing technology will shape the future of the world economy, dramatically improving everything from healthcare records to online voting, and from insurance claims to royalty payments. Brilliantly researched and highly accessible, this is the essential text on the next major paradigm shift. Read it, or be left behind.
