I think a better measure against this is not physical presence, but allowing one individual to exercise their vote any number of times until the ballot period ends.

This means that a malevolent entity that wants to influence votes needs to sequester the voter(s) for the whole ballot period, which is vastly more difficult than putting a gun to someone's head for a single vote.

Executing this at scale so the effect can be statistically significant is even more difficult, and if it's still possible the entity holding the ballot can be assumed to have more pressing issues to care about than fair ballots. :D

Several years ago they used such system on election in Moscow, and there were claims (pretty plausible) that the government used second vote to change voter's vote to another candidate. There was noticeable difference between number of votes and number of voters.

The system used two blockchains: a public one which recorded votes, but without linking to a voter, and a private one that linked voters to vote records in a public blockchain. So the voter couldn't see how many times he voted because this info was on a private blockchain.

So when allowing to change a vote there are several issues:

- how do you invalidate previous vote? You need some way to link those votes, that they belong to the same person which might lead to disclosing their identity

- how do you prevent government from changing your vote by pretending that you voted the second time?

Do you have some links to that? It sounds very interesting.

> how do you invalidate previous vote?

All the votes are public on the ledger, you can clearly see which ones belong to which voter entry.

> how do you prevent government...

The government does not have your private key, also if a hacked vote happens, you as a voter ask for an audit of the vote entries.

I'm not saying there are no problems with electronic ballots, but I'm thinking that with enough time and elbow grease, they can be solved.

This relies on the voter to have enough autonomy to be able to independently access their online ID. It would be easy to circumvent by separating the voter from their ability to identify themselves online. Either by keeping their means of identication from them during the voting period or by being the gatekeeper to the computer where their online ID is stored, for example with a password.

It also relies on the voter caring enough about their vote in the first place to be willing to attempt to do it, with whatever possible personal risk that entails.

The id is a physical card, where the private key and the data attached to it can be accessed through NFC. Sensitive data can be accessed through specific applications, public data can be accessed through a simple NFC reader.

And yes, if the government is corrupt in its entirety, from creating IDs to the ballot process itself and to sequestering citizens, then yes, you're fucked. But I don't see how that would be different for paper ballots or any other means of voting.

This is a interesting idea. I reckon the individual voting period would have to be randomized to ensure that the malevolent entity doesn't just assemble everyone on the last day?

It might be easy to extract this period from a potential victim, since the information would have to get delivered to them in some way.

I think it would already help a lot, that there are some physical limitations on how many people you could gather at the same time.

I actually love this. I always cast my vote on election day because I want to have the most information.

What if I vote early, then the person I voted for has a major scandal the day before the polls close?

Being able to change one's vote would remove all the disincentive to voting early or whenever it's most convenient for you.

If you're changing your vote based on which side was the latest to have a major "scandal", you're part of the problem.

Generally yes, but it depends on what the scandal is.

It works like this in Sweden.

For all Kinds of public elections? I would love to read more. Thanks

Yes, it seems so.

Typically in the US, you can “spoil” your vote and get a replacement ballot, even after you mailed it. So this is already in effect in some ways
