Poverty, legal identity etc. are major concerns in the third-world countries. Data says one-third of children in the world still lack legal identity (sourced from Informationweek). Poverty and lack of food still kill thousands of people. Can Blockchain put an end to all this?
Blockchain is not a magic wand that we can wave to eliminate these basic, yet persistent problems. Poverty, for example, is a product of many factors like lack of education and unpleasant environment. Blockchain must first eliminate this factors to finally erase poverty--I don't see that happening.
