A system and method are disclosed that enable exclusive rights in generic goods to be transferred from one party to another. A party holds an exclusive right to a good through a rescindable capability. When two parties agree on a transfer of the exclusive right to the good, a goods description memorializing the agreement is created which is in synergy with the rescindable capability. The goods description includes an acquire method that is the only method that can extract rights from the rescindable capability with which it is in synergy. The object from which the generic right is being transferred sends a message to the recipient with a reference to the rescindable capability. Upon receiving the message, the recipient invokes the acquire method of the referenced goods description, which returns a new rescindable capability that encompasses the generic right just transferred. Once the recipient holds a reference to the new rescindable capability, the sender has had its rights rescinded. Because details of a transfer are implemented between a rescindable capability and a goods description, rights to goods of any type can be transferred. This is useful in escrow transactions, where a trusted third party with no knowledge of goods being exchanged can effect exchanges of exclusive rights to generic goods by two mutually-suspicious parties.
