Consensus Liveness Attacks

Consensus Liveness Attacks are adversarial attempts to disrupt a blockchain by preventing it from reaching new states or finalizing transactions. Unlike safety attacks, which aim to rewrite history, liveness attacks focus on freezing the network, which can be devastating for derivatives markets that require constant updates.

By spamming the network or targeting key validators, attackers can force a system to stop processing trades, leading to massive liquidation risks. This is particularly dangerous for leveraged positions that need to be adjusted or closed in real-time.

Protecting against liveness attacks involves designing resilient peer-to-peer layers and ensuring sufficient validator redundancy. These attacks highlight the need for protocols to maintain high uptime under extreme stress.
