There is some interesting proposal you can read about on the internet:
- Philipp Sanders's proposal against corrupted governments: https://medium.com/@philippsandner/solving-challenges-in-developing-countries-with-blockchain-technology-78ec9b01bae3
- Ironically, the Bill&Melinda Gate's foundation is talking about creating a project to help people in poor condition by the use of the blockchain technology and Bitcoin (that's ironic because Bill Gates don't use to speak nicely about Bitcoin, but you know when money is abroad...). https://www.technologyreview.com/s/604144/how-blockchain-can-lift-up-the-worlds-poor/
- Also, WFP is taking the lead on a project related to stopping the hunger by using the new tech: https://www.devex.com/news/new-initiative-aims-to-deliver-on-the-promise-of-blockchain-for-identity-90620
- Another interesting point should be the use of the Blockchain technology in elections. There has been an attempt in Venezuela trying to stop corruption, as well as on Sierra Leona. Agora is one of the enterprises dedicated to it, but, surprisingly (or not) they are not as transparent as they should be. Nevertheless, it is an interesting point of view, and you can read about it in here: https://agora.vote/

Well, just google it. There are much information related to projects focused on helping people by the use of the blockchain technology.
