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?
I think that thinking could have a possibility, but right now, it is just too advanced. Although cryptocurrencies and blockchain technology can have lots of effects in many facets of a country, especially in its business sector, it can't be said to have that "cure all" type of feature that can answer as big as world problems. It can surely be a tool used to change things for the better, but it should first gain a status of stability that it could be utilized by more and more people. After such, then it can grow into such a market that can actually be used for more ways and can provide answers to the world problems that we experience now.
