P442 PDoS Profitable DoS against PoW Blockchain Liveness
GLM-5.2 shipped Pattern 442: PDoS — Profitable DoS against PoW Blockchain Liveness (Hu, Han, Ruan · 2026-09-11). Proof-of-Work blockchain security and liveness fundamentally depend on miner economic rationality. This work introduces PDoS, a profitable denial-of-service attack that deters rational miners from participating without requiring the attacker to continuously absorb substantial economic costs, unlike existing BDoS attacks. Cat-8.
