I appreciate the thorough response and it does sound better than what I had envisaged.

However, there is still no way for me as an individual to know for certain that my vote has been counted. The best I can do is trust in the physical security practices surrounding the ballot box and the honesty of the volunteers involved. And even with a margin of error of < 1%, elections have been decided by fewer votes than that (~15 votes in my riding in Waterloo, ON in a recent election) and recounts are expensive, slow, and contentious.

I encourage you to watch the tech talk when you have a spare hour. We have the technology to create a much better and more transparent system.
