A Denial of Service Attack against Fair Computations using Bitcoin Deposits
Jethro Beekman
Abstract
Bitcoin supports complex transactions where the recipient of a transaction can be programmatically determined. Using these transactions, multi-party 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.
