Only a true slashdotter would decry the use of a global ledger for voting.
It also points to the usual propeller-head, hyper-caffeinated style of skimming a subject and "understanding" it. 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.
But hey, lets not let those pesky technical details get in the way of some mouth-breathing millenial having their "moment of snark" about Bitcoin.

Ballot stuffing is a problem though. Just yesterday it was reported that for a nearby local election, one lady sent in 24 absentee ballots. The recipient of those votes won the election by 14 votes. She coordinated others who worked for the campaign, and all were charged. It's difficult to know just how rampant this problem is and how many get away with it.
One-vote-per-person is a fundamental trait of elections. To the extent practicable, we should attempt to ensure people can't vote multiple times.

Both countries, well known for their low levels of corruption, would never use these to suppress undesirable voter blocks! Never would they allow them to become a barrier to voting for anyone without a permanent address.
Given that in some countries' election systems, your permanent address is absolutely essential to knowing where and in which elections you need to vote, a lack of one being a barrier to voting is not necessarily a complaint--equally so, the idea of a place using a voting system that may not be strongly tied to place of residence should not be automatically discounted precisely because it allows you to more easily deal with those who may not have a legally-recognized permanent address and is a reasonable way

You are missing the point.
Ideally a system should be able to prove, to you, that your vote was counted but should not allow you to prove to me that you voted a particular way (lest I offer you money to vote a certain way).

This, and it is a very subtle yet important point, but does have some interesting solutions.
The best I have seen turns every ballot into a series of random tokens. You would reveal the one corresponding to your vote, and write it down.
Later the codes could all be published, and you could check your ballot number vs the code.
The whole system worked by using a couple of special parties that generate the ballots and codes and pre-commit them ahead of time. This way if a person claimed his vote was not correct, his claimed code could be checked against valid codes afterwards.
Additionally anybody could take an extra ballot to be marked invalid and expose all of its codes. These could be checked against the list as a random sampling to validate the list.

From what little I know about the theory of such things, this results in a problem with selling votes - the classic example being that union bosses could then under threat of injury verify that union members voted according to union lines.

There are solutions if you trust the election body.
The most obvious one would be a system where the candidate positions are presented to you in a random order. You get a receipt that says "you voted for presidential candidate #3" and you can verify that against what's shown on screen. You can also verify later that your vote for candidate #3 was counted, but only you (and the election organizers) know which candidate that really was.
Making that work with a public block chain is harder, but there's probably

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 to

My voting system is simple:
There are 6 slots of candidates. A dutch auction is used to fill the slots.
Then FOX, CNN, etc roll a six-sided dice in secret and report the winner. This repeats for 3 months or until all media conglomerates agree on the next President.
It's a better system because it doesn't require lying, thus opening up the talent pool to people who aren't career politicians.

You're going to have to explain how that works, because dollars only equals money where dollars are traded for other currency, goods or services. The government doesn't define the worth of currency, the market does. It's why there are fluctuations in currency values to begin with. Then there's the inflation and deflation problems that contribute to fluctuations in value. So again, what does a physical dollar have to do with how much the dollar is worth? You may use complex sentences and big words.

Nope, they both do. The law of supply and demand. The government controls the supply, the market controls the demand. If there were a widely believed rumor that the US government were about to print one quadrillion dollars, the value of the dollar would drop to almost nothing in an instant.

Bitcoin, like any other currency, gets its value by people willing to offer goods and services in exchange for it. Proof of work is simply used to decide who's version of transaction history is believed, should there be a conflict.
Nothing has intrinsic economic value. Economic value is just an abstraction over how useful people find things, directly or indirectly. That's not an inherent quality of a thing

Certificate revocation and time-release encryption (Score:3)
First option not on the list: revoking self-signed SSL certificates. Normally, it's hard to revoke a self-signed cert, because a potential attacker can just fail to send the user the revocation. But put the revocation on the blockchain, and timestamp the original cert, and it all gets a lot better [github.com].
Second: Time-release encryption. You can build a public key such that the private key can be computed from any future set of blockchain hashes. PDF paper [iacr.org]. That makes it actually time-release, instead of a lot of schemes that release in response to a certain amount of work being done.
