Adversarial Resilience

Definition ∞ Adversarial resilience refers to a system’s capacity to continue operating correctly despite attacks or malicious actions. This property ensures that a blockchain or digital asset system maintains its functionality even when confronted by hostile participants. It involves designing protocols and architectures that withstand various forms of manipulation and disruption. Systems with high adversarial resilience safeguard against data corruption and unauthorized control.
Context ∞ Discussions concerning adversarial resilience are central to the security posture of distributed ledger technologies and their application in digital economics. The ongoing pursuit of robust consensus mechanisms and fault-tolerant designs aims to strengthen this resilience. As digital assets gain broader adoption, the ability of their underlying systems to resist coordinated attacks remains a critical area of research and development. This continuous improvement directly influences user trust and market stability.
