Common oracle design and implementation

[LouisTsai-Csie]

Summary

Please give a short summary of this research topic.

Given that the blockchain operates within a closed environment, protocols requiring real-world data often rely on oracles as intermediaries. Oracles serve as the bridge between external data sources and smart contracts. What are the existing oracle design patterns, and how do they differ from one another?

Description

Please provide a detailed description to the topic.

Numerous protocols rely on oracles to calculate asset prices, commonly referred to as "price feed oracles." Two prevalent types are on-chain oracles, such as the TWAP oracle used in Uniswap V2, and off-chain oracles like Chainlink, which aggregate data from external sources and submit it to the blockchain. Delve into these oracle designs and their underlying rationale for a comprehensive understanding.

@Kaiserouo I assigned you, please take a look, thank you.

@Kaiserouo For this topic, at least you need to compare the Uniswap TWAP oracle and Chainlink price feed oracle, their implementation, design, advantage and disadvantage. Please let me know if you have any more question.
