A Denial of Service attack against fair computations using Bitcoin deposits

摘要

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. (C) 2015 Elsevier B.V.
