Attack Cost

Definition ∞ This refers to the financial or computational resources required to successfully execute a malicious action against a blockchain network or protocol. It quantifies the expense involved in an attack, such as a 51% attack or a smart contract exploit. A higher attack cost generally indicates greater network security and resilience against such threats.
Context ∞ ‘Attack Cost’ is a critical metric discussed when assessing the security posture of various blockchain networks and decentralized applications. News outlets often report on security vulnerabilities where the estimated attack cost is relatively low, prompting concerns about network integrity. Understanding this concept is vital for evaluating the robustness of different blockchain protocols and the safety of digital assets operating on them.
