I've read Herdando de Soto's books, Herdando de Soto argues that unless you can actually have interest in your home it's very difficult for you to start a business or have any wealth created. Blockchain have gone to presidents of Egypt and other countries and said we could register every single house in your country; the 90% of the houses that the people don't actually own -- they just build their houses on random bits of land. We can give them home ownership and then you can create a revolution of business and people being able to start businesses from scratch.
This is from an interview on CNBC Africa. Blockchain's tendrils will only grow and grow and grow.
