I think when blockchain and IoT will be synchronized then it will bring more transparency, fair business interface as well as distributed system without a third party and the next 4/5 years is going to see most of applications of blockchain along with IoT. I can see Oaken is evolving as a great technology in the context of IoT applications and it can reckon the concept of smart cities in a much a better way. Good hunt.

Thank you and Have a great day.
