## On-Chain Data Integrity Review

On-Chain Data Integrity Review is the process of verifying that the data recorded on a blockchain is accurate, immutable, and correctly interpreted by protocols. This involves checking that the inputs from oracles, such as price feeds, are reliable and not subject to manipulation.

The review ensures that the protocol logic correctly processes this data to trigger financial actions like liquidations or interest rate adjustments. It involves auditing the bridges and communication layers that transfer data between different chains or off-chain sources.

If the data feeding the protocol is corrupted or delayed, it can lead to catastrophic financial errors. The review confirms that the consensus mechanisms and data verification protocols are functioning as intended.

This is essential for maintaining the truthfulness of the financial state on-chain. It ensures that users and automated systems can rely on the data to make informed and secure financial decisions.
