While less spectacular than in the case of the Third World, the potential of blockchain to fight poverty in developing countries deserves a mention.
There are many countries where the strength of the fiat currency is not enough to ensure a fair sharing of wealth, but at the same time access to mobile phones and the Internet is common enough for almost anyone to use blockchain. Venezuela, Cuba, and some other countries from Latin America are good examples.
Using blockchain makes possible to eliminate central agents, such as governments and banks, regarding payments and sharing information. It makes possible to access knowledge, jobs and money out of their frontiers, which may make a difference for many people.
