Blockchain is not a small thing and it is as wide as the world wide web and the best composite application would be BLOCKCHAIN+IOT and it is the most awaited synchronization which can change the machine-human interface to machine-machine interface and where almost everything can be automated in a cost effective way and the futuristic version of technology will be the composition of Blockchain and IoT. It has vast potential too.
Do not forget that the blockchain application has not yet happened on enterprise level and unless that happen we can not say that Blockchain is done. In fact I see this technology at the starting point of where the entire world stand and waiting to deliver when the tech-savvy Blockchain technology becomes a common man's cup of tea.
