You have really written a beautiful post on Blockchain technology in our lives. It has been around for quite some time and it is. good.

I think the most essential feature of the blockchain technology is the security it brings to data stored in it and how it makes the transmission of these data very efficient.

I bet to differ Abit about this point. Security is an important component but not the most essential. The most essential is Decentralization I think..

Good luck in the contest
