Generalization on Commodity

• The SAM can transfer ownership of an electronic commodity as an atomic part of the transaction.
• For some types of commodities (such as contracts, or signed things), the SAM can transfer ownership in such a way that the original owner need never be involved--and the object can be resold several more times without ever leaving the SAM network.
• For commodities that are electronically controllable, the SAM's coprocessor can itself directly execute the result of a transaction.
• For some types of commodities, like encrypted network links, transferring data from one link controlled by Alice to one controlled by Bob would require a trusted party anyway. A SAM could execute the deal as well as performing this cryptographic transformation as a result of the deal.
