The Blockchain for Good is a non-profit organization governed by the French 1901 law. Its mission is to build bridges between the blockchain ecosystem and the actors involved in what is known as sustainable development. Since 2018, it has brought together researchers and civil society through an open and participatory science approach, focusing on three key actions: (1) collecting data on impact-driven projects built on blockchains, (2) mapping and analyzing these projects by field of activity, and (3) sharing, exchanging, and fostering dialogue.
