Optimistic Protocols for Multi-Party Fair Exchange

        We describe a generic protocol for fair multi-party exchange of electronic goods over unreliable networks with non-repudiation, where goods are either signatures (i.e. non-repudiation tokens of public data), confidential data, or payments. The protocol does not involve a third party except for recovery over a reliable network.
