You logging into the voting machine is recorded when you vote. Information about who you voted for is not recorded.
And how can you be certain that when the votes are counted, your vote is being included? Having something recorded on the blockchain (or any other public record) doesn't help at all with that; you still have to trust the people counting the votes to count them fairly. Or if the votes are counted by machine, you have to trust those who built and operate the machine. If somebody queries the totals after the election, they can't use the blockchain records to check that the total is correct; conversely it's possible for a malicious actor to stuff ballots without ever recording it in the blockchain.
There are proposals for cryptographic voting systems that work properly. When you vote, your vote is recorded so that you can check that it was counted (and anyone can check that the count includes all votes cast); but you cannot find out or demonstrate what the vote was. This is an interesting area of research but it is a lot more complicated than just saying 'add something to the blockchain'. Doing that by itself adds nothing.
You can use blockchain to authenticate that a vote was cast without recording what that vote was.
Could you elaborate on how that would work exactly? It's not an easy problem to solve.
If you had bothered, you'd know that you can sign a message using your private key that proves indeed, that you did something on the blockchain, whether its voting or whatever.
Right. But how do you do that while ensuring a secret ballot? In other words so you *cannot* prove, whether you want to or not, who you voted for?
There are suggested protocols for having a verifiable yet secret ballot, but they are not completely straightforward. Unless the secret ballot part is sorted out properly, recording all votes in a public ledger (be it the blockchain or anything else) doesn't give a free and fair election.
Yes, but still significantly less evil than the crew that replaced him.
That seems to have been true in the long run, for the most part.
However, the important thing is that he was evil enough to set up the conditions for what followed. The brutal oppression under his regime primed the population for a radical shift, and that's what allowed the Islamists to build up support for their movement.
Of course, the Islamists pulled a huge bait-and-switch, and dealt with all parties in bad faith, but it's extremely unlikely they would ever have been anything but a political footnote if the US and UK hadn't engineered the ouster of the previous democratic government to make room for the Shah.
Then don't let people know that you're rich. There are plenty of towns you could move to that probably wouldn't recognize Bill Gates and definitely not recognize the creator of Minecraft. I know I wouldn't recognize him.
If you are Bill Gates, or even Notch, the cat's going to get out of the bag sooner or later.
Now maybe if you managed to lay low long enough, people would be okay at pretending to ignore the "new" circumstances once your identity were eventually revealed, but it's never going to be the same.
The solution of this problem is trivial and is left as an exercise for the reader.
