Data Tampering Resistance

Data tampering resistance refers to the technical and cryptographic safeguards that prevent unauthorized modification of information as it travels from an external source to a smart contract. This involves end-to-end encryption, digital signatures, and hashing mechanisms that make it computationally infeasible for an attacker to alter the data without detection.

In the context of price feeds, resistance is achieved by ensuring that every data point is signed by the source and verified by the blockchain network. If any modification occurs, the signature verification will fail, and the smart contract will reject the corrupted input.

This is vital for maintaining the accuracy of financial calculations, such as margin requirements and liquidation thresholds, which rely on precise data. Robust resistance protects the protocol from exploits that aim to trigger artificial market events.
