Price Oracle Latency
Price oracle latency refers to the time delay between a change in the real-world market price of an asset and the update of that price within a blockchain-based derivative protocol. Because protocols rely on oracles to trigger liquidations and update collateral values, any delay can lead to incorrect risk assessments.
During high volatility, even a few seconds of latency can mean the difference between a solvent position and a liquidation failure. If the oracle reports an outdated price, the liquidation engine may fail to trigger when it should, potentially leading to bad debt.
Attackers may attempt to exploit this latency through front-running or sandwich attacks to manipulate the outcome of liquidations. Reducing oracle latency is a primary focus for improving the security and reliability of decentralized finance protocols.
