“In paper based systems, you and other volunteers”
No, 99.99% of “you” go home and “trust the system” to some poll workers, many with major bias and incentives
“In paper based systems, you and other volunteers”
No, 99.99% of “you” go home and “trust the system” to some poll workers, many with major bias and incentives. Many of “you” don’t turn out to vote or are disenfranchised by simply living too far from the polling place or not being able to take time off work, when you could have just voted from your app.
Certain parties even rely on suppressing turnout. (Can you guess which party does that in USA? Hint: it’s the one that closed 1600 polling stations right after the Voting Rights Act got neutered, and then got mad about mail-in ballots ruining their carefully laid disenfranchisement plans during the pandemic.).
In fact, if you want the election to be “secured by multiple distrusting parties”, that is exactly what byzantine-fault-tolerant cryptographic protocols (which power many blockchains) are designed to do.
(how do you fix an error in the Merkle tree, even if everyone agrees it happened?). Even if you have an extremely corrupt county, that doesn't generally matter in the grand scheme of things; and its extremely unlikely, as any citizen in that county can stop the corruption by simply participating in the process themselves.
You are literally arguing from a double standard. In a paper election, somehow “any citizen” by themselves can stop the corruption… by simply participating in the process.” Yeah sure one guy exposes the entire corrupt county, with no ability to prove how anyone voted, why didn’t a single Belarussian and Venezuelan think of that? LOL” And on the other hand, when you have tons of anonymous irrefutable proofs by participants submitted publicly, you throw up your hands and say “what can we do to fix the merkle tree, even if we all knew it was corrupt?” The point of the trre is to catch errors, prove them and publish the proofs widely. As a society, you then have the proof nexessary to fix errors the same way you’d normally do it — by identifying the corrupt districts, and having a recount or revote just there. And bringing those responsible for tampering to justice.
If you stop conflating all the things and unpack them, you’ll see that adding cryptography makes things strictly better:
1. You have more chances to catch if there have been extra votes cast because the private keys are coming from tokens handed out at registration. In a paper election you might have corruption at registration AND all manner of ballot stuffing later too.
2. Everyone can check their vote and report a discrepancy. Not just the volunteers at the polling places. And all because they can prove how they voted and do it anonymously!
3. Everyone can see exactly which districts are corrupt in giving out fake voter registrations, and where there’s smoke, there’s fire. They can do an audit and guess what, the cryptographic signatures are helpful for creating a PROVABLE trail that implicates the system.
4. The attack surface reduces to pretty much just the voter registration sybil attacks. Eliminating a whole class of problems on actual election day.
5. The results are reported to everyone reliably and quickly, or even in real-time (though the latter is “too good” because it might affect how later voters vote).
There’s practically not a single problem that adding cryptography creates, which wasn’t already present in the paper system. And you know all this because if you honestly asked yourself whether dictators, who want sham elections, would want to do their next election with cryptographic signatures and merkle trees or not — what would be your answer? Be honest. And think about what that means for your argument.
I'm pretty sure there are more than 20,000 polling workers in the USA, so no, it's not 99.9% who go home and trust. And most importantly, for every republican there is a democrat and vice versa, in every polling place, auditing the process in real time.
And the reason you can fix this at the polling station level is simple: as long as the entire state is not captured by a single party (in which case no real elections are happening), the rest of the state can come in and fix the bad locations.
Related to your points:
1. If there are more ballots than registered voters, this is easy to check. It's even better than a private key system, as extra registrations can also be caught on the day of polling, if people actually come in and vote again, whereas extra private keys being handed out will not see an election official again.
2. There is no way to actually "prove anonymously how you voted". To move the needle in any way, you have to come out personally and say "I know I voted like this, but the system shows me as voting like that, here is what it shows when I present my private key". And either way, this is actually a weakness of the system, as it allows trustworthy vote selling.
3. I don't understand how this is supposed to be any easier than in the current system. You still won't know how many people were legally allowed to be registered in that district, so what are you comparing against?
4. No, the threat surface is the entire electronic system. Someone can attack the system and prevent voters from getting private keys, issue corrupted keys, allow more keys than were registered, present the results differently from what is stored in the merkle tree, use side channels to decrypt private keys, exfiltrate data about individual voters, and who knows how many other ways. Plus, if you can vote from anywhere, you can be coerced, especially by family or caretakers, to vote in their presence, or disclose your private key so they can vote in your name themselves.
And all this assumes the system is an actually secure Merkle tree. In reality, it would just be a computer program that takes your vote and shows you some data. What is actually running on the server is impossible for you to know unless you are given access to the hardware and software.
5. Sure, this is a clear advantage.
You are severely underestimating the risks of an electronic system, and only looking at the purely theoretical logical core. All of the systems around it, through which you interact with the core system, and all of the human factors around using the systems, are a huge attack surface. For example, would you trust this system and issue your vote from a phone or PC which you know is infested with malware? If not, then you have to agree that every device is part of the attack surface of this system.
Finally, in relation to your challenge, elections held by dictators are only meant to look like elections in more legitimate countries. So, if most countries hold paper elections (which is by far the majority), then the dictators will put on a show like that. If the majority of countries used electronic voting, dictators would also get electronic voting machines. Still, I don't know of any dictator that bothers to make a show of how free and correct are their elections.
Ultimately none of these details matter given the elephant in the room: you're voting on some app using your private key, and using some app to check with your private key if the vote has been correctly registered. But you have 0 way of knowing if the system is using this data in the way it was presented. For all the info you have access to, the system can just as well work like this:
1. You cast your vote using the private key
2. This gets registered on a server, it remembers "this person voted for X"
3. When you ask the system "who is my vote registered for?" the system tells you "X"
4. When computing the totals used to decide the election, the system returns 90% Y, 10% X, regardless of the actual votes cast.
Now, this very simplistic scheme would be easily defeated by asking them to publish the whole database of votes. But that would just break the anonymity guarantee of the election, so it is a no-go. And if they destroy the relationship between your vote and your private key, then again you can't confirm anything.
By the way, because you were citing Estonia's e-voting, I read up on it a little: they have all of these problems, and more. For now, people choose to trust the government, I assume and hope rightfully. But their e-voting system relies entirely on secure client devices, it relies entirely on trust that the servers are running the published source code, it relies on the proprietary closed-source client app being trustworthy. And people have even hacked their own vote to show that it's possible, which their supreme court found is not a problem with the election, since it was still their own vote. They barely even have some form of verifiability, and even that is relatively new.
I have no doubt that if a pro-Russia party had a realistic chance at winning (such that the populace and the incombent government would accept the results of an election where they won), Russian state actors would hack their systems and seek to get their people elected (whether they would succeed is of course hard to say). As would the USA if, say, a Latin American state used electronic voting and had an election where the decision was important enough. Or China in Africa, or Israel in the Middle East, etc.
> I think we both know that a corrupt government would not want to secure elections with merkle trees and publish them online. Too much chance of being caught, and they’d have no way to fudge the results reliably.
I think you seriously don't understand what a sham election is, what people know about it, and why it is done. Sham elections don't use semi-sophisticated means of voter fraud that could be thwarted by a better voting scheme. They don't have corrupt officials surreptitiously changing or adding a few votes.
They are entirely ceremonial affairs, where both the people voting and all of the officials know what the results will show beforehand. Often there aren't even options on the ballot. Even if there are, people choosing the wrong option will be threatened, possibly arrested for political crimes, etc. Everyone in countries with sham elections is well aware their vote doesn't matter, or it only matters in so far as the wrong vote can be like wearing an "I hate Big Brother" hat out on the streets in 1984.
The purpose of a mock election is to have some semblance of a normal electoral process to have a minimum of plausible deniability to facetiously claim you are following a democratic process. If people overall believed that the right way to do elections is electronically and by publishing a Merkle tree of the results, corrupt governments would hold sham electronic elections and publish made up Merkle trees.
You'll then have stories from journalists going and asking for people to compare their votes against the public tree, and seeing their votes are different. Just like today you have journalists coming back with stories of entire villages voting for the dear leader when local villagers say they didn't even enter the polling station. And it will matter just as little: the ritual of the election is the only thing that matters.
Just to be clear - even though I say “Merkle Tree”, I am not saying the unhashed votes themselves would not be stored in it. The hashes are just to quickly verify integrity of the underlying data leaves (the actual votes people cast).
The anonymity is done between registration and voting. There is a cryptographic mixer like Tornado Cash that is responsible for the unlinkability, by “tumbling” the tokens to anonymize them while still making sure that each person voting legitimately had registered. (Never mind for a moment that the IP address of the voter can be tied to their address, that can be fixed too.)
So yes, ALL the votes are stored and published in the Merkle tree, and ANYONE can challenge the election, not by hearsay allegations but actual PROOF that anyone can verify. Because the public keys of the UX vendors are published along with the Merkle Tree and are caught red-handed signing conflicting votes. Either the corrupt districts or the UX vendors would have to risk literally ANYONE producing a smoking gun. It is that chilling effect that keeps them all honest, and why we have checksums for things in general. Having everyone in the world see proof of fraud is very different than a bunch of villagers claiming to a journalist locally that they hadn’t even voted.
So given this description, tell me directly — doesn’t it ADD a lot of security and reduce the attack surface and make elections standardized, cheaper and far more trustworthy - don’t you see the value in that?
Think about it — this scheme alone allows some great integrity features for elections. The “election Luddites” are essentially claiming that this has ZERO VALUE and shouldn’t even be tried, shouldn’t even be ADDED TO the existing paper systems even if you lost nothing, because it adds NO SECURITY. That is quite a claim given the properties I listed!
More generally, this is how Smart Contracts work and why they are valuable. Thousands of independently run nodes get to check the data and operations, which are public. The entire community benefits, and in fact the results of voting (eg how much UBI to give out) can be used on-chain. By lowering the cost of collective decision-making, blockchain technology enables a whole new level of efficiency (much like red lights enable better traffic flow), making things like elections or large marketplaces available to everyone without “offchain” corruption-peone mechanisms like surety bonds and reliability ratings (remember Lehman Brothers?)

> There is a cryptographic mixer like Tornado Cash that is responsible for the unlinkability, by “tumbling” the tokens to anonymize them while still making sure that each person voting legitimately had registered.
This is not anonymity, it is pseudonimity, if the system then records "person in control of key K voted for X". Sure, it may be impossible to tell who is that person, unless they come out. But that person can prove to anyone they want that they voted for X (assuming the system were trusted, see more on that below), so they can be forced to show someone who they voted for, either through direct coercion or as a condition for receiving money for their vote. In contrast, once you put a paper ballot in the urn, it is impossible for anyone to tell who you voted for.

No, it only gives a false sense of security, which is worse. Everything you are describing relies on trust in the people that build these systems, trust in the people that invent the algorithms, trust in the people that invent the maths, trust in the chosen parameters of the cryptographic systems, and so on. Literally none of what you are describing works if you don't trust in all of these people to be (a) honest, and (b) really really good at what they're doing.
It's infamously easy to screw up an encryption implementation, even given a well known and accepted algorithm. It's even easier to screw up a market system and end up with perverse incentives which were not apparent when the system was put in place (like the infamous, though possibly apocryphal, cobra farms).
I asked you before as well: would you be happy to issue your vote from a PC that you know is infested with malware the CIA/FSB/etc controls? If not, then you must admit that the cryptographic guarantees are only a small part of the security of the process, and the whole thing, from client to network to server, needs to be perfectly secure or the election can be stolen.
And you are proposing to add this to a paper based ballot system that is (a) dead simple; (b) almost universally used; (c) proven secure enough in many thousands of elections.
I'll also note that, as always, the blockchain part is not adding anything to all of this. You can just as well have the encryption guarantees and an open protocol with government-run servers, WWW style; that would have all the same problems, but at least it wouldn't also require some bizarre proof-of-stake (what would even be the stake here???) or wasteful proof-of-work scheme to depend on for security.
Finally, I'll come back to this point:
> not by hearsay allegations but actual PROOF that anyone can verify
Nothing you are describing can prove anything. It all still relies on your claim that you were trying to vote X, but the system registered you as voting Y. It's your word against the system. You can be convinced yourself, but you can't 100% convince anyone else.
Edit: note, I am the same person as tsimiones, just posting from a different account from my work computer; not trying to make it seem like multiple people are taking my position or anything like that.
You’re still misunderstanding how it works.
First of all, blockchains are a third party ledger, which is maintained by many independent nodes are the large ones are infeasible to corrupt by a nation-state. The attack could only happen at the point where you sign transactions for the smart contracts.
Voters are required to use at least 2 devices, such as scanning a QR code on their laptop (which runs Chrome) with their phone (which runs Safari).
The QR code contains (or points to) a vote that is cryptographically signed by one gateway. The website or app on the phone checks this QR code and displays the same result back to you, and you confirm it on eg your phone’s screen.
On both gateways (call them Services A and B) you indicated your preference, and digitally signed it, not just with your own key, but there is attestation by the device’s own private key, which is derived from the vendor’s key, meaning the vendor stands behind what their device or app does.
Let’s assume absolutely every signature service cannot be trusted, including all your crypto wallets, incouding Apple’s secure enclave, everything is designed to be sleeper agent to mislead you on the day of the election. They just really want to change everyone’s vote. You can still prove which services were corrupted!
Let’s say that you got signature Service A and Service B to sign two different candidates during the same chain of QR code confirmations. The proof is there that at least one of the services was corrupt. Even if it happened only once, with one voter. The indelible proof is on a blockchain and replicated so nation states can’t hide it. So no Service would agree to volunteer such a blatant proof of its own corruption, given the cost to its vendor. It would only happen if the Service would be hacked by an employee of the vendor, and that would only hurt the vendor, not the election. The vendor would try to eliminate this possibility as much as possible.
However, if service A one lied to you, and you found out after scanning the QR code with Service B, then you wouldn’t want to submit your faulty vote with service B when it revealed that to you. But the service B would already would have provable dirt on service A. Not conclusive, since the voter could after all be someone who would rather complain about a non-faulty system than vote. I won’t speculate on chances of many registered voters not wanting to vote but simply make up fake complaints about the system, but I don’t think regular users should face penalties for lying, so I’ll just accept this as a serious possibility. All I will say is, these people are similar to those who stay out and don’t vote now. It’s an issue of “turnout”.
But even in this scenario (of a malicious voter rather than malicious service), Service B would then be required to do the reverse — process your other vote, and sign the transaction, then anonymously submit it to Service A to be signed. Service A would have to either refuse to cooperate with Service B, or sign it. After that, you’d be given a QR code presented by Service B, and verify it with Service A.
Of course there could be far more than just a of Services A and B. There could be 100 services (eg web-based) and voters could be required to go through a chain of 3 of them, as determined from a random oracle (ie they don’t get to pick who to collude with). You’d get the list of 3, and an honest service would simply redirect you to the next one as you bounce between two devices via QR codes.
Service A on Laptop
Service B on Phone
Service C on Laptop - done
Everything that’s signed goes into a third-party gossipped / replicated log (doesn’t have to be a blockchain, there doesn’t have to be a total order). This log / heap is what contains the indelible proofs that can be found out anytime after the fact, which is why every service must be careful to mess up even once.
You see, there is a huge difference between actors/nodes simply voting between some arbitrary choices A and B, and nodes voting while also following cryptographic constraints amd creating a trail where cheating at any step can be caught and proven later. The latter is much harder to pull off and, given costly enough consequences, creates chilling effects and strong incentives to be honest. This is what many BFT algorithms get wrong and why they fail in the presence of over 33% malicious nodes.

We're still chasing around the same issue. Say the following happens:
1. I open my laptop, and I say I want to vote for Alice. It presents a QR code.
2. I open my phone and scan the QR code. It says I'm voting for Bob.
I repeat this five times and the same happens. What do I do next? Assume I'm also afraid of publicly admitting I'm voting for Alice. Assume this only happens for a small part of the electorate, say 1-2%.
Here is another scenario: I have a sophisticated malware on both my phone and laptop.
1. I open my laptop, and say I want to vote for Alice. The malware connects to a voting server and asks it for a vote for Bob. The voting server replies with a QR code that proves I voted for Bob. The malware on my laptop then prints a QR code that says "hey, phone malware! this person thinks they voted for Alice, and here is the validation for their vote for Bob".
2. I open my phone and scan this QR code. The malware on my phone tells me "Yup, this is a vote for Alice". I press "Vote", and it sends the information from the Bob vote to the validation server. I'm happy that I voted for Alice, but the system has recorded that I voted for Bob, with all necessary signatures.
3. Even if the system includes the ability to check your vote, I can't prove to anyone else that I was trying to vote for Alice.
Now, if this happens to a huge number of people, the election may be contested and re-done (in a functioning democracy; in a dictatorship, it was the whole point). But what if it happens to a small minority, enough to only steal 1-2% of the vote? What if it's additionally well targeted to people that aren't generally trusted by their peers, so that they will be easily written off as cranks?
Also, what if I come out claiming this is what happened to me, but this didn't actually happen? What if I'm a celebrity, or a well-known scientist? What if I'm actually Alice herself, shamelessly lying to my voters that the election was stolen?
Another scenario that defeats this scheme, that I haven't even touched on before:
I am coerced, defrauded, or payed to share my private key with a third party. They vote in my name from the comfort of their own home, with every single system you described attesting that my vote was cast legally.
Try to prove that I shared my key, while still preserving the anonymity of private key <-> individual person association.
And this doesn't even get into how the private keys are given to every single person in a country without revealing them to a third party in the first place, but also without generating valid private keys for people who aren't entitled to vote.
In reality, instead of 2 distrusting parties (democrats and republicans) in each polling place, there would be 100 mutually competing / distrusting services that would like nothing better than to expose the other services as frauds with indelible cryptographic proofs. That's the basis of Byzantine Fault Tolerant consensus protocols.
In the first scenario, to answer your question, if service 1 kept being faulty (saying you vote for Bob when you voted for Alice) then you'd simply increment your nonce and try another VoteChain that starts with service 52. The VoteChain determines which 3-4 services out of the 100 are consulted, and in what order. You have a few nonces, up to 10. If you claim ALL random services you've tried are faulty, then yeah, go ahead and sit out the vote, you're probably just a liar and complainer. They don't know who you are, so the chances of them being good for 100 other people and specifically not good for you, 10 times in a row, are very small. And even if it was true, that's 1 vote out of many. Now if this happens more frequently, then these services could be dropped from the 100, pending investigation -- which is easy since the services don't know who is voting, could be the police. So why would the services risk being on the hook for this?
In all your examples, you're begging the question.
In 1 and 2 in the second scenario, you assume that your own phone AND your own laptop AND all the servers all have malware and are undetectably malicious. In that case, you have much bigger problems -- they can, for example, steal money from many people, send messages to ruin relationships and reputations, and much more. In your example, large swaths of people can't trust any of your devices. In that case, society as a whole is cooked. It's not quite as paranoid as "not trusting the cryptographic algorithms and math", but it's close.
Let's assume that the Trusted Computing Base isn't compromised. Because if it is, then you may as well also distrust all the poll workers as being corrupt, and the media as reporting the wrong result, etc. After all, this system is being added ON TOP of the existing system, so it can only ADD security.
Regarding giving out private keys without revealing them to a third party, I have already said that's a strawman. They'd be giving out tokens that are used to prove that you have 1 vote, and they are put through a mixer by the people, like pulling numbers out of a hat. On the other hand, the public/private key pairs are generated by the person on their own devices (e.g. in the secure enclave). You can't steal these keys so easily, unless you steal the person's phone AND coerce them to enter biometrics when voting. But then you could just make them do a wire transfer or anything else.
Look, about this constant refrain about "coersion, defrauding, etc" this happens already. Voter intimidation can happen already, preventing you from going to a polling place, or simply disenfranchising you making it too inconvenient or far to go. It's a much BIGGER problem now, that would be REDUCED if you could vote from your phone, and on net you'd have an improvement.
Also, since in the USA you don't need to present ID while voting, a person could tie you up in your basement and go vote as you. Since in your hypopthetical world, illegal coersion and force and defrauding has no consequences apparently, then that would mean in CURRENT voting schemes, people could just vote as others.
Heck, in Australia, I could even get someone in trouble by voting AS THEM. Their name would appear twice. In Australia, they fine you if you didn't show up to vote. So without IDs, you can get in trouble either way (if you don't show up, or if you supposedly voted twice).
I'm telling you, the same people who claim IDs are totally unnecessary for voting, are the same people trying to find attacks on cryptographically secure voting. But many of these "rubber hose attacks" are already doubly possible in today's "physical" voting schemes, along with all the other downsides (the cost, the speed, the scandals, as you can see with uncertainty in elections around the world).
30% of the USA thinks that the 2020 election results were illegitimate. You can't wave that away as "well, our paper elections are great, they're just partisan hacks/deluded". I bet you with cryptographic elections, that 30% would be far less, and elections / referendums would also be cheaper and easier to do all the time. You wouldn't need to do it once every 4 years and spend billions AND it would be more reliable.
