Besides payments, what are some new and creative uses for the Bitcoin (or any other cryptocurrency) protocol?

1. Proof of existence: http://www.proofofexistence.com/ http://www.proofofexistence.com/ show that you are the original author of a creative work before putting it out there in the world where anyone can copy the bits. 2. Eternal love messages: http://aterna.org/love/ http://aterna.org/love/ Embeds messages on the florincoin blockchain and the message is stored as long as there is at least one peer on the network (Bitcoin doesn't support such long messages). 2b. Encoded messages in the Bitcoin blockchain: http://www.righto.com/2014/02/ascii-bernanke-wikileaks-photographs.html http://www.righto.com/2014/02/ascii-bernanke-wikileaks-photo... - these are hex encoded messages. Florincoin above allows to store data itself in the blockchain. 3. Autonomous Corporations: http://btcgeek.com/dawn-of-autonomous-corporations/ http://btcgeek.com/dawn-of-autonomous-corporations/ Futuristic stuff that's possible with the blockchain technology - creating 'corporations' that no one owns or profits from but are fully self-sufficient.

Has anyone looked into voting systems through bitcoin? Here's how I would design it. Please correct any flaws: Make a wallet with a tiny amount of bitcoin for each voter and distribute the wallets. Each candidate gets an empty wallet. Publish the public address of those wallets. Voters send their coins to their chosen candidate's wallet. The candidate with the most bitcoins (only counting txns from the distributed voting wallets) wins. Voters could potentially use a mixing service or coinjoin to preserve anonymity? Keep in mind, I'm talking about pennies or less worth of bitcoin so there's no financial element to any of this. Just taking advantage of the bitcoin platform. As a bonus, there's a permanent, unalterable public record of the votes.
