Zero Transaction Fee Attack

Definition ∞ A Zero Transaction Fee Attack is a malicious attempt to overload a blockchain network by submitting a large volume of transactions with no associated fees. This can cause network congestion, slow down legitimate transactions, or even lead to a denial-of-service for honest users. Such attacks exploit network design where zero-fee transactions are permitted or prioritized poorly.
Context ∞ The threat of zero transaction fee attacks is a significant concern for blockchain networks that prioritize low or no transaction costs, as it can compromise network stability and usability. Developers continuously implement and refine mechanisms, such as dynamic fee markets and resource prioritization, to mitigate these attack vectors. Ensuring network resilience against such exploits is crucial for maintaining operational integrity.
