And indeed, the way it's done somewhere else on this planet is you show up, vote, get your thumb inked so you can't go to another poll and vote a second time, and that's all there is to that.
If the distributed system is not partitioned, you can show up to vote anywhere and they tell your home precinct that you've voted; then during vote counting the precinct where you voted tells your home precinct "add the following to your vote totals".
If the system is partitioned -- either from network outages or remote polling locations or mail-in ballots -- then your ballot goes into an envelope and is physically sent to your home precinct in the week following the election, to be verified and included in the count.
If the network is not connected, your three remote ballots go into envelopes marked "dh2022" and in the week following the election they are physically transported to your home polling location, at which point they see that you tried to vote three times, set those ballots aside, and call the police.
It also allows fraud by voting for people who didn't show up.
Yep, this is something the US can no longer claim, sadly.
This can't possibly be a serious solution. A quart of acetone costs $2.
It actually stains fingernails in such a way that the ink only truly disappears when the nail grows.
From Wikipedia:
> Election stain typically stays on skin for 72–96 hours, lasting 2 to 4 weeks on the fingernail and cuticle area. The election ink used puts a permanent mark on the cuticle area, which only disappears with the growth of the new nail. It can take up to 4 months for the stain to be replaced completely by new nail growth. Stains with concentrations of silver nitrate higher than 18% have been found to have no added effect on stain longevity, as silver nitrate does not have a photosensitive reaction with live skin cells. This means that the stain will fade as new skin grows.
