BC voting

Secure protocol for blockchain voting:

First, a voter registers some kind of authentication system (dongle, registration card, password, all of the above?)

A voter authenticates.    

Vote workers (or a machine printer?) gives them a 'ballot' which is a pre-decided card with QR codes on it representing a signed transaction from the election commisssion account
to the address. then 

Ballots can easily be independently checked if they have already been used or if they do not go to the proper locations.

Ballots can also be transmitted securely at the time of registration.

Ballots that have already been confirmed can be printed and claimed
