Very informative video. I like the idea of blockchain being used to register voters and voting (1 person, 1 vote). I just wonder how this will pass the voter ID law blockade where the Obama admin contested voter ID laws (just showing a State issued ID card) in some States. The use of blockchain will also be helpful for real estate issue. Banks buy and sell mortgages constantly and it gets confusing. There have been cases of people paying off mortgage, yet the bank in possession of title at the time tries to evict the true owner and sadly succeeds sometimes. I believe a documentary call "Clouded Titles" was made addressing this issue.
