The All-out Attack strategy reveals that miners can exploit Pay-Per-Share schemes to maximize gains while leaving honest miners and pool operators at a disadvantage.

A simple tweak to a known blockchain attack—limiting the withholding time—yields 22x greater rewards for attackers in realistic scenarios, exposing a major weakness in pooled mining incentives.

Sharing randomness across all servers in a graph-based database system boosts private information retrieval capacity, outperforming schemes where randomness is tied to individual message replicas.
