The technology isn’t there. Because it can’t be. As I said previously in the thread: the biggest security hole is ALWAYS legitimate use. There absolutely positively HAS TO BE some layer of control to make sure the system allows all proper US citizens to vote and ONLY proper US citizen to vote. And the minute you have that layer of control you have a system that can be gamed and or hacked. And we haven’t gotten into the counting system which in the end also has to have some level of centralization, and therefore vulnerability to gaming or hacking.
I’m 46 and a software QA engineer. I’m paid pretty well to do exactly this, look at the design of a system and point out its flaws. And any and all voting systems have variations of the same flaw. Much like how any OS that allows you to install software will allow you to install malware, any voting system that allows voting will allow fraudulent voting. It’s the unavoidable security hole. You might make the system BETTER (although in this case I don’t think you will, centralized data causes single failure points, so instead of having to hack a bunch of voting machines they only need to hack 1, or maybe 1 per congressional district) but any idea that you can make it truly secure and immune to fraud is panacea thinking and flawed.
Illegitimate use can never be prevented whether completely manual or completely automated or something in-between. But the credentials can be controlled in a blockchain system. The user generates their own credential, whether illegal alien or citizen. The next step is they register to vote. That is a process where they turn in the public key and their proof that they are a citizen. The government official looks at the proof and adds the public key into the database of voters.
Can the database be hacked and new public keys added? Maybe, but the addition of those keys is in a block chain and such fraud would be easy to detect. Can illegal aliens present fake citizenship credentials? Possible, but only to the extent they can today.
The beauty of the block chain once the registration step is done is that it cannot be hacked.
