Sending a message to a destination anonymously so that the destination cannot figure out who the originator was, and ensuring that the message reaches the destination untampered with, can be a difficult problem. Chaum's mix-net solves this problem but offers little motivation for a person to set up a mix-net server. This paper discusses a method that not only allows monetary payments as an incentive to create a public mix-net server, but also provides some fraud detection at the time a message is being sent. Also compared with other methods, the method described here can be considered reasonable from the users perspective, because if the message is not delivered the user does not lose any money.
