An Optimistic Fair Exchange (OFE) protocol is a good way for two parties to exchange their digital items in a fair way such that at the end of the protocol execution, both of them receive their items or none of them receive anything.

Our results include the following: – Fair exchange cannot be securely reduced to the problem of fair cointossing by an r-round protocol, except w...
