Systemic Oracle Failure

Definition ∞ Systemic oracle failure describes a widespread breakdown or manipulation of multiple oracle networks that supply external data to blockchain protocols. This event can cause extensive disruptions across numerous decentralized applications reliant on accurate off-chain information. Such a failure could lead to incorrect liquidations, protocol insolvency, or a loss of trust in the broader DeFi ecosystem. It represents a critical vulnerability for interconnected smart contracts.
Context ∞ The risk of systemic oracle failure is a significant concern in decentralized finance, often discussed in the context of market stability and security. Debates center on developing more resilient, decentralized, and diverse oracle solutions to prevent such a catastrophic event. Mitigating this risk is crucial for the long-term viability of the DeFi sector.
