Definition ∞ Adaptive blocking attacks involve an adversary dynamically adjusting their strategy to disrupt blockchain operations. This sophisticated form of attack typically observes network conditions and then modifies tactics to impede block propagation or manipulate transaction ordering. Such actions aim to undermine the stability and fairness of a distributed ledger system.
Context ∞ These attacks pose a persistent threat to the security and decentralization of certain blockchain protocols, particularly those reliant on proof-of-work where mining power concentration exists. Protocol developers continuously implement upgrades designed to mitigate these dynamic and evolving threats. Understanding adaptive blocking attacks is crucial for assessing the robustness of various digital asset networks.
