thanks for your insightful comments Leo. I agree at a larger scale this kind of solution is currently not very feasible. You mentioned all the research that the bigger organisations conduct. Someone would still need to play that part. I do however feel that some communities can use technology in ways which they can directly help themselves. With mosquito nets and water pumps that kinda thing. Too many banks are involved with R&D for blockchain but organisations not focussed on making profit also need to start looking at this tech!
