Conditional Resource Exhaustion describes a scenario where a system’s computational or storage resources become depleted only under specific, often adversarial, input conditions. This state is not a general system failure but a targeted degradation caused by particular sequences of operations. It often stems from vulnerabilities in how resources are allocated or managed based on transaction parameters.
Context
In digital asset systems, Conditional Resource Exhaustion can represent a significant security concern, particularly in smart contract execution environments. Attackers might craft transactions that, while appearing benign, trigger excessive computation or storage use when processed. News reports on network congestion or transaction processing delays in blockchain systems sometimes relate to such resource contention issues.
A new class of Conditional Resource Exhaustion Attacks is formalized, exploiting Turing-complete execution to decouple validator work from fee compensation, fundamentally compromising blockchain liveness.
