Estonia is becoming the touchstone and proof of good e-voting practice. It has failed its audits in the last elections. See
- http://en.wikipedia.org/wiki/Electronic_voting_in_Estonia, the wikipedia page
- https://www.verifiedvoting.org/report-on-the-estonian-internet-voting-system-2/
- https://estoniaevoting.org/, the home page of the independent auditors
- https://estoniaevoting.org/wp-content/uploads/2014/05/IVotingReport.pdf, the report of the independent auditors
These are serious gaps.
