## Oracle Aggregation Models

Oracle Aggregation Models are mechanisms used in decentralized finance to consolidate data from multiple independent sources into a single, reliable price feed. In the context of cryptocurrency and financial derivatives, smart contracts require accurate external information to execute functions like liquidations or trade settlements.

Because a single data source can be manipulated or experience downtime, aggregation models combine inputs from various nodes, APIs, or decentralized oracle networks. These models typically employ statistical techniques such as calculating the median or a weighted average of the incoming data points to filter out outliers and malicious reports.

By diversifying the data origin, these systems enhance the security and integrity of on-chain price discovery. This approach mitigates the risk of oracle manipulation attacks where an adversary might attempt to skew a price feed to trigger unfair liquidations.

These models are foundational for maintaining the peg of stablecoins and ensuring the correct valuation of collateralized positions. As market microstructure evolves, these aggregation techniques have become increasingly sophisticated to handle high-frequency data volatility.

They serve as the critical bridge between off-chain market reality and on-chain execution logic. Without robust aggregation, derivative protocols would be highly vulnerable to flash loan exploits and price manipulation.
