As I understand it, there are no bad actors post-ante. Either your transaction is accepted or not. If, for example, someone steals your private key and moves money from your wallet to theirs, it is, according to the block chain, their money, even if that's not true according to any jurisdiction on the planet.

Which is kind of where I wonder how overrides can be put in place. How can one return that money? How does one force a bad actor to hand over the private key for the newly flush wallet ?

Yeah, I’m not quite sure I perfectly grasp where wallets come in. It’s not covered in the article, since it’s focused on how the blockchain works at a pretty basic level. Protecting transactions is still a mystery, since it seems one could with the implementation shown, with access to the chain and all transactions, just craft a block that transfers everything to themselves.
