# Oracles ⎊ Definition **Published:** 2026-03-12 **Author:** Greeks.live **Categories:** Definition --- ## Oracles Oracles are decentralized or centralized services that provide external data, such as asset prices, to smart contracts on a blockchain. Since blockchains cannot natively access real-world data, oracles act as a bridge to feed accurate price information into the protocol. In the context of liquidations, oracles are essential for the liquidation engine to determine the current value of collateral and the debt position. If an oracle provides incorrect or manipulated price data, it can lead to erroneous liquidations or allow under-collateralized positions to remain open. Therefore, the security and reliability of oracle networks are paramount to the proper functioning of financial derivatives on-chain. They are the single source of truth for the protocol's risk engine. - [At the Money Option Risk](https://term.greeks.live/definition/at-the-money-option-risk/) - [Institutional Custody](https://term.greeks.live/definition/institutional-custody/) - [Time to Expiration Impact](https://term.greeks.live/definition/time-to-expiration-impact/) - [Price Manipulation](https://term.greeks.live/definition/price-manipulation/) - [Recency Effect in Order Flow](https://term.greeks.live/definition/recency-effect-in-order-flow/) - [Distribution Assumption Analysis](https://term.greeks.live/definition/distribution-assumption-analysis/) - [Delta-Gamma Neutrality](https://term.greeks.live/definition/delta-gamma-neutrality/) - [Cross Border Financial Law](https://term.greeks.live/definition/cross-border-financial-law/) ## Glossary ### [Oracle Network Monitoring](https://term.greeks.live/area/oracle-network-monitoring/) Network ⎊ Oracle Network Monitoring, within the context of cryptocurrency, options trading, and financial derivatives, represents a critical layer of infrastructure ensuring data integrity and reliability for decentralized applications and trading platforms. ### [Data Source Diversity](https://term.greeks.live/area/data-source-diversity/) Mechanism ⎊ Data source diversity functions as a critical framework for mitigating oracle manipulation risks in decentralized finance by aggregating pricing feeds from multiple independent liquidity providers. ### [Market Manipulation Prevention](https://term.greeks.live/area/market-manipulation-prevention/) Strategy ⎊ Market manipulation prevention encompasses a set of strategies and controls designed to detect and deter artificial price movements or unfair trading practices in cryptocurrency and derivatives markets. ### [Data Verification Processes](https://term.greeks.live/area/data-verification-processes/) Algorithm ⎊ Data verification processes within cryptocurrency and derivatives markets heavily rely on algorithmic validation to ensure transaction integrity and data consistency. ### [Data Integrity Solutions](https://term.greeks.live/area/data-integrity-solutions/) Authentication ⎊ Systems governing data integrity in crypto derivatives ensure that all incoming price feeds and execution requests originate from authorized entities. ### [Blockchain Technology Stack](https://term.greeks.live/area/blockchain-technology-stack/) Architecture ⎊ This foundational arrangement defines the multi-tiered structure necessary for secure distributed ledger operations within financial ecosystems. ### [Oracle Security Risks](https://term.greeks.live/area/oracle-security-risks/) Algorithm ⎊ Oracle security risks, within decentralized finance, fundamentally stem from vulnerabilities in the code governing data retrieval and transmission to smart contracts. ### [Erroneous Liquidations](https://term.greeks.live/area/erroneous-liquidations/) Event ⎊ Erroneous liquidations occur when a trader's collateralized position in a derivatives market is closed out prematurely or incorrectly due to system failures, oracle malfunctions, or extreme market volatility. ### [Smart Contract Vulnerabilities](https://term.greeks.live/area/smart-contract-vulnerabilities/) Code ⎊ Smart contract vulnerabilities represent inherent weaknesses in the underlying codebase governing decentralized applications and cryptocurrency protocols. ### [Decentralized Data Infrastructure](https://term.greeks.live/area/decentralized-data-infrastructure/) Architecture ⎊ Decentralized data infrastructure serves as the foundational distributed ledger and peer-to-peer network layer facilitating trustless information transmission across crypto-asset markets. ## Discover More ### [Collateral Liquidation](https://term.greeks.live/definition/collateral-liquidation/) ![A high-tech device representing the complex mechanics of decentralized finance DeFi protocols.
