3 big changes. koeppelmann noticed that multisig addresses would allow votecoin holders to collude by holding all the votecoins in a big multisig. It is no longer possible to send votecoins into a multisig address. Paul pointed out that it is possible for voters to prove to each other how they will vote, by revealing their transactions ahead, and that this makes truthcoin insecure against collusion. So I added a 10th transaction type which is a punitive slasher-style tx. It punishes people for sharing their votes ahead of time. The third and final change is in how peers rank each other for downloading blocks. This change allows us to download blocks much faster
