The gold standard is Australian Ballot -- private voting, public counting -- cast at poll sites, immediately tabulated when polls close, then results posted publicly. Just a TLDR. There is so much more. Election administration is pretty involved. Electronic voting breaks the Austalian Ballot in two ways. Whereas a ballot box protects voter privacy by being a secure one-way hash (physical shuffle), all electronic systems record the order ballots are issued then cast (necessary for auditing). Electronic voting also obliterates the physical chain of custody. FWIW, to protect privacy, postal ballot processing has to properly batch (by precinct) before opening. Your jurisdiction probably doesn't do this, due to cost and timeliness.
