We haven't managed such a thing for commerce and finances, though. Elections have far more consequences than money moving, as well, so failures are much worse and less tolerated.
In NYC recently I did some ecommerce. I paid for 5 delivery meals and 4 of them were stolen by the drivers. Amazon is full of fraudulent products. Banks in the US are full of loopholes, like ACH not providing sufficient auth. Trust in commerce and finances online are low. Systems fail frequently, and "only money" is lost by big corps usually, so it's not considered a big deal to the general public. I would not use that as a model for elections.
