## Data Aggregator Reliability

Data Aggregator Reliability refers to the trustworthiness and accuracy of services that collect data from multiple sources to provide a single, reliable price feed. These aggregators are the gatekeepers of information for many DeFi protocols.

If an aggregator is compromised or provides faulty data, the protocols relying on it will likely suffer. Reliability is built through redundancy, cryptographic verification, and decentralized governance.

Aggregators must be resistant to censorship and manipulation to maintain the integrity of the ecosystem. As DeFi grows, the importance of these aggregators becomes even more pronounced.

They are the backbone of the oracle layer. Evaluating the reliability of an aggregator is a fundamental step in conducting due diligence on a protocol.
