What Is a “Trusted Execution Environment” (TEE) and How Does It Secure Data?

A TEE is a secure area of a main processor that guarantees the confidentiality and integrity of the code and data loaded inside it. Oracle nodes can use TEEs (like Intel SGX) to process off-chain data securely.

This ensures that the data is not tampered with during aggregation and that the node's private keys are protected, providing a verifiable link between the off-chain data source and the on-chain report.
