I wonder why we relay on ATM's and computers our money then... Isn't that sopposed to be even more important than a vote? I genuinely don't understand. Or heck, the stock trade market still uses paper? I only see them with computers in there... Hmmm... Why is this so different and insecure? Doesn't the paper casted votes end up being counted up by a computer with a spreadsheet or other method? The rockets we launch to the moon or space, don't we trust these machines to do the tasks we usually used to to with abacus back in the day? I sense some paranoia here...

The "World's Most Expensive Pencil" would be great to make voting accessible to people who can't handwrite, for whatever reason. Citizens with dysgraphia are still citizens and still deserve to have their votes counted, even if they would have difficulty writing their votes on a paper ballot.
Seagull Australis (2 days ago)
Yes. And it would also be absolutely unnecessary to those who are perfectly able to handwrite. Such equipment should be available to those who need them, but should not be the standard.

Le vote électronique c'est comme les machines à sous, elles sont programmées pour rendre de l'argent toutes les tant de pièces introduites. Donc les votes électroniques peuvent être programmés pour que tous les tant de vote pour la personne à éliminer que le programmeur a désigné, se transforme en vote pour le Président que vous ne vouliez pas.

Yet I can bank online and banks still operate, surely if hacking a system like polling was as easy as you're saying no bank would have ever risked online banking as surely it's still safer to go into a bank and deal with a teller over the counter in person?

This is where blockchain could actually help tho.
Seagull Australis (2 days ago)
Having each voted identifiable would compromise the entire election. Did you even watch the video?
Aditya angara (2 days ago)
+Seagull Australis an immutable database would be useful to e-voting wouldn't it ? Once a vote is cast and sent onto a block it couldn't be edited if you tried along with an identifier for the person. (Safe within the timespan of the whole process)
Seagull Australis (2 days ago)
No. It actually couldn't. Do you not know what a blockchain is?
Maverick Hargrave (25 days ago)
What if it worked like this: the elector takes a card and punches a hole with a small standardized paper punch in the right place, to mark his candidate. Then, when it's time to count the votes, the people responsible for that job use a laser assistant to count the votes faster. If you use holes instead of pen or paper, it's harder to erase or use ink that disappears.
Tomasz Świrski (27 days ago)
Voting should NOT be anonymous. That would solve all the problems.
Howdy8x 629 (19 days ago)
why is it anonymous in the first place? i get it may cause some conflict but that is something that needs to be confronted and resolved instead of pretended to not exist which eventually turns to total out lash .

dudes, its pretty easy. - send peeps a voting code with letter - vote on home computer with that code, but you also get some kind of private UUID for your actual vote - when vote is done, votes where counted and evaluated you get a checksum for the overall of all votes. against this number you can check your UUID if its really counted and was counted with the original code. the last step ensures that there was no tempering and votes are legit. basically this is what we use for modern authentication.

What happens when quantum cryptography is a big thing?
Seagull Australis (2 days ago)
Then we will have quantum cryptography. That changes absolutely nothing about elections.
Kevin Stauffer (1 month ago)
At a high level the reason crypto currencies work is because of two things: 1. The cryptography aspect confirms the identity of the user creating a transaction 2. There is no central location receiving all the information and telling everyone else the results Electronic voting of the future will have to work the same way. We use cryptography to confirm that you are in fact eligible to vote and that it’s you casting the vote rather than someone else impersonating you, and then that information is broadcasted publicly, not just to election officials, so that anyone in the country could gather all the votes and count them up. The end results will be determined by a consensus.
Kevin Stauffer (1 day ago)
Seagull Australis The government could act as a third party by publishing the list of eligible public keys. That would reintroduce anonymity without centralizing the counting process.
Seagull Australis (2 days ago)
No. The concept of you cryptographically signing your vote is a one which kills anonymity in voting. It is crucial that every vote is anonymous.

Just make online voting with social security number.... Then require a random 10% of those voters to go to a voting center and be instructed to vote exactly how they did online. If an overwhelming majority of that 10% vote in person and online are the same, then the voting hasn't been rigged... Right? P.S. I'm talking about computer voting from home online.

The Brazilian electronic voting system circumvents almost all the issues you presented, by having, just to name a few, USB ports that are not accessible without brute-force physical attack to the machine, no internet connection whatsoever, several people within view of the machine at all times during voting, randomly selected members of the public to serve as voting clerks, and many more. See Iuri Fiedoruk's comment for more safety mechanisms.

I think all systems have their advantages and disadvantages. We have seen plenty of cheating using paper ballots as well, both from the party currently in power and from the opposition. Overall I think a digital system can be made safer than relying on ink and paper counted and checked by people, but it has a long way to go before it is safe and accepted/trusted enough.
brian reese (1 month ago)
ok, but does anyone have a way to do elections that would work? paper ballots in an box dont work because someone could just stuff the box or lose my vote, or the whole box. so i feel that an election should be verifiable, both personally, and total number of cast votes, it should be secure from directed attacks against, and it should be anonymous, and it should be trustable and understood by the public; is there anyway to do all of these?
Biky (1 month ago)
Voting? Ah, you mean giving someone power and privilege that nobody else has naturally, in order to abuse and succumb the minority of the population (or in some cases, the majority, when the votes are split among many small parties and the largest minority wins). If "John" told you that you had to obey him or he would violate you, that would be wrong. Even if John claims that because he and his friends are in the majority, you must obey or be punished, that would still be wrong. Even if John and his friends vote to have an institution or authority work on their behalf and that you must obey its dictates or be punished, that would still be wrong. If you understand this basic concept, then you understand that government neither has the legitimate or lawful right to violate you just because some people decided to vote for it.

Scott Enders (2 months ago)
Cryptography and blockchain are solutions none the less. The real problem, as he explained is developing the platform in an unbiased way that is 100% accurate to the physical vote. Many people do not understand the way blockchain functions and have little trust in it. I was also highly skeptical but I now see that there is an active community of enthusiasts that is rapidly expanding and everyone in this community all utilize blockchain to manage their finances. If people are willing to put money on a blockchain and are able to walk away with confidence that the blockchain is going to ensure the money stays where you left it, that’s a big victory for blockchain and another step for furthering it’s utility.

Is voting more sensitive than banks and money? I find it interesting that it works fairly well to keep my money safe online. Is that because the banks having their own interest in keeping it safe and do not want to manipulate my money since then it would be of disadvantage for them. I know banks getting hacked from time to time but really not that often.

give every person a unique voting ID Number, then have every vote publicly displayed along side these IDs. ez You can self verify your vote went through correctly. You can self verify that if you didn't vote your ID doesn't have a vote attached to it.

Couldn't block-chain and crypto-voting solve almost all of these issues?
宋岡哲 (1 month ago)
​+GreenMonkeySam With paper votes, it isn't easy to sell your votes unless you chose to vote by mail (which is a bad idea already). You receive the ballot paper only after you "authenticate" in the polling station, then, you'll be monitored so that you may not give the paper to others, bring it out of the station, or reveal the marking before you drop the ballot into the ballot box. An ideal polling station might also disallow any electronic from going in. This is how you get anonymity and security with paper voting. With e-voting you just can't get anonymity and security in this level, with or without blockchain (anonymity and security are almost mutually exclusive in the realm of digital data). What blockchain provides is non-repudiation and temper resistance of the votes *after they are cast* . The scheme would still be vulnerable on the part *before* votes are cast. E.g. corrupted/hacked voting hardware.
GreenMonkeySam (1 month ago)
​+宋岡哲 I did say solve almost all of the issues. It does solve the issues stated in the video. But even now someone could "sell" their vote to someone else i.e. pay me x to vote for so-and-so.
宋岡哲 (1 month ago)
Short answer: No. Blockchain is not the magic solution to all the problems that electronic voting could have. One of it is anonymity: Blockchain is not a completely anonymous scheme. You may still use some tokens for voter identity verification. And the tokens can be sold to others before they are cast.

You told us what's the problem. But i am sure that electronic voting machines can be better than ballot boxes... As even an illitrate person can mess with it. So as you told us the problems i am sure we can find a solution. And solution might involve trusting at least one person with something big.. but it's better than trusting 100 people to do their job properly. Like 1 person you trust can be loyal or not loyal.. but most probably if you know him personally .. you can figure that out. So i think EVM actually reduces chances of errors and also protects from unskilled people being hired to mess with machine. I think there's a solution. Ps: BTW i am not saying EVM as in machine connected to internet. I am talking about machines that does nothing but count and take votes and anything can be tampered i agree.. but with proper security and less people being involved.. in which all can be trusted.. is a way to go.

Why are you all going on about secret ballot? The ballot is not secret in the UK. Every ballot paper has a serial number and that number is recorded against your name. Now it may be that the data is only used if there is some concern of fraud. But the fact remains that if anyone who has access to the ballots and the register can determine exactly which ballot is yours.
