I am not sure that blockchain technology can be used in the election polls or not but if we can implement this technology in elections we can eliminate fake voters and non favourable leaders from the government ruling place and can make this world as better place than now.
If this technology can be implemented then any government will implement that? What is your view on this!
I also think about it, there are many problem in election polls in my country and the problem is never can be solved. I think blockchain technology will solve this problem and reduce the cost. I also heard that there are some countries that already apply this for their election polls. But I think for now it only can be aplied in developed countries which has good infrastructures.
