In September 2015, the UN General Assembly adopts Agenda 2030 and the 17 Objectives of Sustainable Developments (SDG ). This global community move aimed at managing jointly, through increased co-operation, a number of major interconnected global challenges. To inform how actual policies advance toward these goals, an evaluation framework and measuring processes are necessary to ensure compliance with states’ statistics standards. On the other side, crowdsourcing of voluntary evaluations from individuals linked to databases through user interface - a standard IT technology - could bring many benefits for this purpose. Allied with a major breakthrough in network technologies (blockchain) it offers various technical solutions to the barriers to voluntary contributions to trusted continuous SDG evaluations (=monitoring) from people. Together we argue below how it can also constitute a powerful and legitimate actor in the global community by imposing its voice at the highest national and global levels.
