Pyth Network is a next-generation oracle solution, designed to bring high-fidelity (HiFi) data to decentralized finance (DeFi). It is a product of collaboration between major players in traditional finance and DeFi, aiming to provide the infrastructure necessary for substantial DeFi market growth. Pyth Network focuses on offering legally authorized access to unique datasets, featuring sub-second update speeds, sophisticated output, and aggregation methods, and an effective incentive system to ensure data accuracy and prevent malicious breaches.
The core of the Pyth Network is its protocol, which aggregates inputs from various data providers to produce a single aggregate price and confidence interval every 400 milliseconds for each price feed. This mechanism operates on an application-specific blockchain called Pythnet, a proof-of-authority chain running a version of the Solana validator. It is separate from the Solana mainnet-beta and combines inputs from different providers to produce a unified price and confidence interval for each feed. The aggregation algorithm is designed to robustly counter outliers and manipulation, appropriately weigh each data source based on accuracy, and reflect variations between data providers' prices in an aggregate confidence band. This data is then streamed to Wormhole, ready for use in decentralized applications (dApps).
Pyth Network stands out with unmatched update frequencies and data confidence intervals, operating on Solana's high-performance blockchain for near-instantaneous updates. It publishes confidence intervals for all price feeds, a unique feature that enhances accuracy, especially during high volatility. Pyth aggregates first-party data from multiple publishers, reducing manipulation risks and maintaining data integrity through decentralization. The network also introduces two flagship products: Pyth Price Feeds, offering over 350 low-latency price feeds across various asset classes, and Pyth Benchmarks, providing a historical archive of prices from Pyth Price Feeds for standardized calculations and presentation. These products address speed, asset coverage, and accuracy issues of legacy oracles and are designed for integration with a broad range of blockchains including Ethereum, BNB Chain, Polygon, and many others.
