# On-Chain Data Feed ⎊ Area ⎊ Resource 2

## What is the Data of On-Chain Data Feed?

An on-chain data feed provides real-time price information directly recorded on a blockchain, enabling smart contracts to execute financial logic based on external market conditions. This data is essential for decentralized derivatives platforms to calculate collateral requirements, trigger liquidations, and settle contracts accurately. The reliability of this data feed is paramount for the integrity of the entire system.

## What is the Oracle of On-Chain Data Feed?

The oracle mechanism is responsible for securely bringing off-chain data onto the blockchain. On-chain data feeds often rely on decentralized oracle networks that aggregate price information from multiple sources to mitigate single-point-of-failure risks. The design of the oracle determines the frequency and cost of data updates.

## What is the Integrity of On-Chain Data Feed?

The integrity of the on-chain data feed is critical for preventing manipulation and ensuring fair outcomes for derivatives traders. If the data feed is compromised, attackers can exploit smart contracts for profit, leading to significant financial losses for users. Robust security measures, including economic disincentives and decentralized data aggregation, are necessary to maintain data integrity.
