Jamming is a denial-of-service attack on Lightning channels. The attacker initiates payments (jams) that consume the resources of routing nodes and then fail. Jamming decreases the profitability and reliability of routing nodes. The attack is cheap and difficult to prevent.| Bitcoin Problems
Users of decentralized financial networks suffer from inventive security exploits. Identity-based fraud prevention methods are inapplicable in these networks, as they contradict their privacy-minded design philosophy. Novel mitigation strategies are therefore needed. Their rollout, however, may damage other desirable network properties. In this work, we introduce an evaluation framework for mitigation strategies in decentralized financial networks. This framework allows researchers and develo...| IACR Cryptology ePrint Archive
