Blockchain and IoT, both are envisaged to bring in a plethora of advantages including better control, communication, transparency and more significantly realizing digital trust without any third party intervention. Both of these technologies have immense potential for exploitation in a smart nation concept. The advantages being realized are potent enough for definite implementation ahead but they come with an austere package of security concerns which if not taken care at the design stage can lead to pandemonium beyond control because of the billion plus connected things. Even at design stage, one can appreciate that it will be envisaging beyond control to close all security vulnerabilities and zero day's exploits of future. But then Blockchain is an inexpugnable solution to shut all these securities imperils. This paper builds upon the advantages of the union of these two evolving technology behemoths, their union and solutions vide Blockchain to the challenges in the way ahead.
