Secrecy of the vote is necessary to prevent against such things as vote buying and manipulating others to vote a certain way through intimidation (these days more of a problem outside of US).

The validating that a vote was counted appropriately probably could be used in a block chain type mechanism, but may need to be more with a zcash type of implementation.

I'm a true believer that more tech is not the right answer for voting security. (At least for the near term). Voter-verified paper ballots, that can be run through open-source tabulators and then stored for a subsequent mandatory audit would be ideal (3-5% is the target I think we've gone for in Cali).
