How do you verify your vote is counted correctly and not made up? Having the voting ledger would be cool - you could verify with the "transaction id" and how it's recorded.
I don't know about other countries, but here in New Zealand elections are monitored by the Electoral Commission who employ people to watch every step of the process. In addition every political party is entitled to send scrutineers to polling places and the count. The boxes are shown to the scrutineers who verify it to be empty, then sealed. The boxes are never taken out of sight. Every step of the process is under multiple eyes.
This seems to work well. It's possible to double vote by visiting multiple stations but in practice this is rare. It does happen but the electoral commission do analysis on the votes to ensure it didn't affect the outcome. Those responsible are prosecuted.
There is no way to implement verifiable voting which is not vulnerable to voter coercion. If you can verify your vote, so can the person threatening you.
The way to ensure the ballot is secure is to have a fully publicly verifiable end-to-end process. You should be able to watch the ballot box from the moment you put your vote in, all the way to the count.
