A Denial of Service attack against fair computations using Bitcoin deposits

Abstract: Bitcoin supports complex transactions where the recipient of a transaction can be programmatically determined. Using these transactions, multiparty computation protocols that aim to ensure fairness among participants have been designed. We present a Denial of Service attack against these protocols that results in a net loss for some or all of the honest parties involved, violating those fairness goals.
