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?
We cannot just simply say blockchain will just totally eradicate every concern we have always had but it will surely disrupt a lot of things from the way they have been done over the years which would then make it easy for the economy to grow,.
But we have to understand that depends on adoption of it by any country, how things are still being done since things would still want to be in the centralized manner when it comes to government, so the only way out that I see is when decentralization just take the space but we all know that is one thing that is hard to see happen.
Blockchain alone cannot do any magic but human innovation and enhancement based on requirements may bring big revolutions in this world. We may expect big changes to happen on how people save and spend in coming days which may lead to further developments in other industries and sectors.
