• Oracle tài chính (financial oracle): #PythRoadmaр is a specialized oracle network that provides real-time market data (cryptocurrency prices, stocks, foreign exchange, commodities, etc.) with low latency and from "first-party" sources (exchanges, market makers, financial institutions) directly. 

• Pull-based model: Instead of continuously "pushing" data from the oracle to the blockchain, Pyth uses a "pull" model — applications request data as needed; data is updated when pulled. This helps save fees and resources, while also controlling when the data is pushed on-chain. 

• $PYTH Private blockchain / Appchain – Pythnet: Pyth has developed Pythnet — an app-chain (based on Solana's code) — to enhance computational capabilities and data processing, facilitating higher frequency data output.
