That’s why I’m specifically wondering about the public aspect of the bounty—it presupposes that the assassin will be publicly known and able to conduct financial transactions afterward, and that the sponsor will be able to openly make good on their promise.
The sponsor would have to be able to publicly demonstrate that the assassin was paid, though—otherwise they could claim to have paid the bounty while keeping the money, and the assassin couldn‘t protest without exposing their identity.
