This Open Access book outlines ideas for a novel scalable and above all sustainable
financial system. We all know that today's global markets are unsustainable and global
governance is not effective enough. Given this situation could one boost smart human
coordination sustainability and resilience by tweaking society at its core: the monetary
system? A Computational Social Science team at ETH Zürich has indeed worked on a concept and
little demonstrator for a new financial system called Finance 4.0 or just FIN4 which combines
blockchain technology with the Internet of Things (IoT). What if communities could reward
sustainable actions by issuing their own money (tokens)? Would people behave differently when
various externalities became visible and were actionable through cryptographic tokens? Could a
novel participatory multi-dimensional financial system be created? Could it be run by the
people for the people and lead to more societal resilience than today's financial system (which
is effectively one-dimensional due to its almost frictionless exchange)? How could one manage
such a system in an ethical and democratic way? This book presents some early attempts in a
nascent field but provides a fresh view on what cryptoeconomic systems could do for us for a
circular economy and for scalable sustainable action.
