Definition ∞ A forced transaction queue is a mechanism designed to ensure that specific, critical transactions are processed and included in a block, often under emergency or time-sensitive conditions. This can involve a prioritized queue or a dedicated channel that bypasses typical network congestion. Its primary purpose is to guarantee asset recovery or critical state changes even during periods of high network load. This helps maintain system liveness.
Context ∞ Discussions around forced transaction queues often arise in the context of rollup security and withdrawal mechanisms, particularly during periods of network stress on layer-1 blockchains. News might report on how such queues are designed to protect user funds in worst-case scenarios, preventing assets from being locked indefinitely. This feature functions as a security measure to maintain system operationality.
