So now you have an infinite number of unique IDs anybody can get a hold of and put in the chain without verifying they’re a US citizen who is eligible to vote and hasn’t already voted? At some point there has to be central control, and central control is hackable.
I am not going to try to explain the blockchain technology to you. Nor do I know how they propose doing this.
My point is that the technology is there, it is safer than any other technology out there now. And, I am guessing it will be better than the crap systems they use now.
Of course, there are a lot of 60+ year old people here on FR who are terrified of technology, and who will never trust anything younger then themselves. Which is hilarious based on the “never trust anyone over 30” cries of their youth.
