The transformative power of block chain technology should be seen as an opportunity for national and international institutions to defend the rights of those they represent and to accelerate our collective progress towards meeting the United Nations’ Sustainable Development Goals. We recently partnered with volunteers from the UN Refugee Agency (UNHCR), the UN Development Programme (UNDP), and the World Economic Forum (WEF) to explore how block chains support a vast array of sustainability, humanitarian, and environmental initiatives. This white paper explains how this unconventional technology works and how it is already being used to pursue conventional ends. It illustrates how block chains have brought new levels of efficiency and effectiveness to the fields of development aid, supply chain management, renewable energy, economic growth, and several others.
