Tom Scott explains why electronic voting remains insecure and why proposed solutions like open source software and blockchain do not solve its fundamental scaling issues.

…sily (or would want to use up their time to understand it). I almost have a PhD in the hard sciences and I don't fully understand the finer details of block chain. I think I would have to write my own implementation to fully appreciate it. Simplicity and the ability to explain the system to every American is a requirement of any voting system. 1 link to this video…

Tom Scott made an excellent summary of why electronic voting is a bad idea, and explicitly covers both open source and blockchain as proposed solutions (hint: they don't solve the problems that make e-voting bad) link to this video

On “Blockchain voting is overrated among uninformed but underrated among informed”

I think the Tom Scott video on electronic voting from years ago remains the most convincing argument to me that it's a bad idea ( link to this video ). To summarize, even assuming you can solve properties like correctness, censorship resistance, privacy and coercion resistance. The fundamental problem with digital is that any exploit of any of these properties you ever have scales really well. Messing with a paper election requires a lot of people working together across the entire country. A digital hack just requires one smart person

Many bank transactions can be reversed, and the ones that can't can be covered by insurance or self-insurance. You can't practically speaking reverse a tainted election. Anyway, I'll let Tom Scott take it: link to this video

On “Debian decides to allow secret votes”

I am not familiar with Debian's practices, but electronic voting can't work for a nation because: - centralization (there must be a central, corruptible place where the voters are authenticated or the votes are counted) - software is untrustable: link The USA has had a Diebold voting scandal. Other countries are using a paper-based voting process which can be supervised by third parties. link Relevant watching: Tom Scott: Why Electronic Voting Is Still A Bad Idea link to this video One possible solution could be ZCash ( link ) but it has had its own problems ( link ).

Here's Tom Scott's second video explaining why electronic voting is a terrible idea: link to this video Electronic voting machines and companies that manufacture them should both be illegal. Yet their use is widespread in America. The primary reason they're a bad idea is they make widespread election fraud easy. There is no good faith reason to use them.

…hed at. If you put it into business terms, would you trust an employee or vendor who told you that everything was alright, did not allow you to perform checks and audits and mocked both your and external partners concerns 0 about it? I don't think so. If the government is indeed for the people and not vice versa, then this is not acceptable. 0 link to this video Tom Scott's video about e-voting. Funniest rebuttal I saw on Estonian social media was that we are secure, since he is talking about e-voting, but we have i-voting. So I guess once we will call it c-voting, it will be even better...?…

…so many problems with electronic voting that I don't even know where to start. At least with physical ballots we can manually recount if we need. And that's before we even start talking about how current systems are basically swiss cheese for hacks, just look at the voting village for the last couple of defcons.
