The progress of electronic commerce has been stymied by the lack of widely accepted network payment mechanisms. A number of proposals have been put forward, and each one o ers a slightly di erent protocol and set of features. Yet none has achieved the critical mass to become an accepted standard. We believe that there will continue to be a variety of payment mechanisms, so in this paper we prop...
