# Oracles

## Overview

Blockchain oracles act as bridges between smart contracts and real-world data. They provide essential off-chain information such as price feeds, random numbers, and event outcomes that blockchains cannot access natively. Oracles vary in design, with some using push models (regular on-chain updates) and others using pull models (on-demand data requests). The quality of an oracle is measured by its speed, accuracy, cost-efficiency, and security against manipulation.

## Oracles

### Pyth

The [Pyth Network](https://pyth.network/) is the largest first-party Oracle network, delivering real-time data across [a vast number of chains](https://docs.pyth.network/price-feeds/contract-addresses). Pyth introduces an innovative low-latency [pull oracle design](https://docs.pyth.network/documentation/pythnet-price-feeds/on-demand), where users can pull price updates on-chain when needed, enabling everyone in the blockchain environment to access that data point most efficiently. Pyth network updates the prices every 400ms, making Pyth the fastest on-chain oracle.

Users can also opt to use push model oracles through Pyth by running a [scheduler](https://docs.pyth.network/price-feeds/schedule-price-updates/using-scheduler).
