Payment channel networks (PCNs) enhance blockchain scalability but face denial-of-service (DoS) attack risks. Attackers flood channels with spam transactions, exhausting node resources and disrupting services. Resilience strategies include rate limiting, transaction prioritization, and channel fee adjustments to deter malicious actors. Dynamic routing protocols can reroute transactions during attacks, maintaining network availability. Additionally, decentralized identity verification and reputation systems help identify and isolate attackers. By combining these measures, PCNs can mitigate DoS threats, ensuring reliable and efficient off-chain transactions while preserving blockchain scalability benefits.
