The book is presented as a collection of essays discussing the new banking and money transfer models, and also addressing challenges and threats faced with said models. Among the topics covered are peer-to-peer lending, crowdfunding and bank vulnerabilities, using mobile money and blockchain technology for remittances and the boundaries of a self-organised economy. In essence, it provides a new perspective on economic models which move the field from describing monetary flows to understanding complex social processes that underlie the dynamics of the economy.
