Oracle Data Sanitization

Mechanism

Oracle data sanitization serves as a critical defensive layer in decentralized finance, functioning to filter and validate incoming off-chain price feeds before they influence on-chain smart contracts. By employing statistical filtering techniques such as median absolute deviation or threshold-based clustering, the system effectively ignores outliers that would otherwise trigger erroneous liquidations or arbitrage exploits. This procedure ensures that financial derivatives and options markets maintain price integrity despite potential failures or manipulation at the data provider level.
