# Pull Model ⎊ Area ⎊ Resource 2 --- ## What is the Model of Pull Model? The pull model describes a data delivery mechanism where a smart contract or application actively requests information from an external source, typically an oracle, only when that data is required for execution. This approach contrasts with the push model, where data is automatically broadcast to the smart contract at regular intervals. The pull model offers greater flexibility and reduces unnecessary on-chain transactions. ## What is the Data of Pull Model? In the context of decentralized derivatives, the pull model ensures that the smart contract retrieves the most current price data at the precise moment of settlement or collateral check. This on-demand data retrieval minimizes the risk of using stale data, which is critical for accurate options pricing and liquidation mechanisms. The user or a specific function initiates the data request, paying the associated gas fee. ## What is the Efficiency of Pull Model? The efficiency of the pull model lies in its ability to reduce gas costs by avoiding continuous data updates to the blockchain. While it introduces a slight latency in data retrieval, it optimizes resource usage for applications that do not require constant real-time updates. This model is particularly suitable for options contracts where data is only needed at specific points in time, such as expiration or exercise. --- ## [Real-Time Collateralization](https://term.greeks.live/term/real-time-collateralization/) ## [Multi-Source Hybrid Oracles](https://term.greeks.live/term/multi-source-hybrid-oracles/) ## [Real-Time Data Feed](https://term.greeks.live/term/real-time-data-feed/) ## [Data Feed Cost](https://term.greeks.live/term/data-feed-cost/) ## [Black-Scholes Model Verification](https://term.greeks.live/term/black-scholes-model-verification/) ## [Black Scholes Model On-Chain](https://term.greeks.live/term/black-scholes-model-on-chain/) ## [Black-Scholes Model Inadequacy](https://term.greeks.live/term/black-scholes-model-inadequacy/) ## [Hybrid Order Book Model](https://term.greeks.live/term/hybrid-order-book-model/) ## [Black-Scholes Model Manipulation](https://term.greeks.live/term/black-scholes-model-manipulation/) ## [Spot Price Oracle](https://term.greeks.live/term/spot-price-oracle/) ## [Oracle Systems](https://term.greeks.live/term/oracle-systems/) ## [Black-Scholes Model Integration](https://term.greeks.live/term/black-scholes-model-integration/) ## [Stochastic Volatility Jump-Diffusion Model](https://term.greeks.live/term/stochastic-volatility-jump-diffusion-model/) ## [Real Time Price Feeds](https://term.greeks.live/term/real-time-price-feeds/) ## [Security Model](https://term.greeks.live/term/security-model/) ## [Risk Model Calibration](https://term.greeks.live/term/risk-model-calibration/) ## [Black-Scholes Model Vulnerabilities](https://term.greeks.live/term/black-scholes-model-vulnerabilities/) ## [Hybrid Oracle Architectures](https://term.greeks.live/term/hybrid-oracle-architectures/) ## [Black-Scholes Model Vulnerability](https://term.greeks.live/term/black-scholes-model-vulnerability/) ## [Interest Rate Model](https://term.greeks.live/term/interest-rate-model/) ## [Data Feed Real-Time Data](https://term.greeks.live/term/data-feed-real-time-data/) ## [Off-Chain Data Streams](https://term.greeks.live/term/off-chain-data-streams/) ## [Prover Verifier Model](https://term.greeks.live/term/prover-verifier-model/) ## [Black-Scholes Pricing Model](https://term.greeks.live/term/black-scholes-pricing-model/) ## [EIP-1559 Fee Model](https://term.greeks.live/term/eip-1559-fee-model/) ## [Utilization Curve Model](https://term.greeks.live/term/utilization-curve-model/) ## [Model Risk](https://term.greeks.live/term/model-risk/) ## [Pull Data Feeds](https://term.greeks.live/term/pull-data-feeds/) ## [Risk Model](https://term.greeks.live/term/risk-model/) --- ## Raw Schema Data ```json { "@context": "https://schema.org", "@type": "BreadcrumbList", "itemListElement": [ { "@type": "ListItem", "position": 1, "name": "Home", "item": "https://term.greeks.live" }, { "@type": "ListItem", "position": 2, "name": "Area", "item": "https://term.greeks.live/area/" }, { "@type": "ListItem", "position": 3, "name": "Pull Model", "item": "https://term.greeks.live/area/pull-model/" }, { "@type": "ListItem", "position": 4, "name": "Resource 2", "item": "https://term.greeks.live/area/pull-model/resource/2/" } ] } ``` ```json { "@context": "https://schema.org", "@type": "WebSite", "url": "https://term.greeks.live/", "potentialAction": { "@type": "SearchAction", "target": "https://term.greeks.live/?s=search_term_string", "query-input": "required name=search_term_string" } } ``` ```json { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question", "name": "What is the Model of Pull Model?", "acceptedAnswer": { "@type": "Answer", "text": "The pull model describes a data delivery mechanism where a smart contract or application actively requests information from an external source, typically an oracle, only when that data is required for execution.
