Blockchains can be designed to allow confirmation of something already known without revealing it to parties that only have access to the blockchain.

  "We want you to vote for X or else Y" or "Prove you didn't vote for X or else Y" attacks are possible as long as verification is possible. This seems like a huge drawback of blockchain voting. Edit: Example - people vote against unpopular candidate Paul. Paul then stages a coup and takes control of government. He then asks you to provide a receipt that you voted for him on the blockchain or all your property is confiscated by the state.

    Honest question, why would Paul need to do that if he took control of the government? I mean, "I can't" is an honest answer here, since its unrecoverable and many people won't care enough to try to verify their votes.

      > Honest question, why would Paul need to do that if he took control of the government? He might want to to punish enemies or reward supporters; “control of government” id, in practice, not infinite power, and people often use such a position to, first and foremost, secure the position. > I mean, "I can't" is an honest answer Which is a reason Paul might want to let it be known that some form of accountability will be asked in advance. (Which he also might due to push the actual vote results; if it is projected to be close, expecting a cost for voting the “wrong” way if one candidate wins will likely shift some votes.)
