Abstract: A system and method for networked exchange are disclosed. A system for networked exchange comprises an internal proxy (140); an exchange processor (120) in communication with the internal proxy (140); a database (130) in communication with the internal proxy (140) ; an external proxy (150) in communication with the internal proxy (140); and, a communications network (110) connected to the external proxy. A method for networked exchange comprises 8 steps. Those steps are (1) specifying a mode of operations for an exchange; (2) identifying a commodity for the exchange; (3) listing information about the commodity; (4) accessing of the listing by a potential purchaser; (5) accessing the network-based exchange by the potential purchaser, (6) processing information generated by the potential purchaser, the information comprising a negotiation; (7) concluding the negotiation; and, (8) clearing the concluded negotiation.
