Extensive and relevant collection of arguments why DLTs (and IoT, AI), fundamentally offer interesting solutions for sustainable development. I clearly agree with the potential. Important to note, however, is that for many of the key problems, the issue is not technology but rather processes and/or stakeholder dynamics/politics. Therefore, any sound solution depends, apart from the tech, on the relevant stakeholders, those with subject-level knowledge. Key for getting working solutions on the ground is thus the right type of cooperation. The most promising and tangible solutions present themselves where, apart from the administration on DLT, capturing and analysis of data can be automated (hence the importance of IoT, AI). You may find #Hack4Climate and the Climate Ledger Initiative interesting concerning climate, Fintech4Good and applications relevant to other SDGs.
