## What is the Oracle of Pull Model Oracles?

Pull model oracles operate on a request-response mechanism where smart contracts initiate a query for data when needed. This approach contrasts with push models, where data is automatically broadcast at regular intervals. The pull model allows for greater control over data freshness and reduces unnecessary on-chain updates, potentially lowering gas costs for protocols that do not require continuous real-time data.

## What is the Mechanism of Pull Model Oracles?

The mechanism of a pull model oracle involves a smart contract requesting data from a decentralized network of data providers. The providers respond to the query by submitting the requested information, which is then verified and aggregated on-chain. This design ensures that data is only updated when a specific action or calculation requires it, optimizing resource allocation for decentralized applications.

## What is the Efficiency of Pull Model Oracles?

The efficiency of pull model oracles is particularly relevant for derivatives protocols where data updates are only necessary at specific trigger points, such as option expiration or liquidation events. By avoiding continuous data pushes, these oracles reduce network congestion and minimize transaction costs. This model offers a balance between data integrity and operational cost, making it suitable for certain types of financial derivatives.
