Paper ballots, hand counted, twice. This is still the most optimal current system as it much harder to corrupt at scale. The proprietary systems we have can easily be corrupted at the time of aggregation. There have been enough examples of people demonstrating simple tally hacks that there is no way to know if any election is genuinely counted accurately. That's not to say that its impossible. I think block chain has some promising potential here but databases that are proprietary are completely untrustworthy today.
