On-chain Attestation

Note: On-chain attestation is different from TEE attestation.

On-chain attestation can be produced via Zero-Knowledge proofs or other attestation services, providing another layer of validation.

Privacy Inference Module

Computation is built on top of the Trusted Execution Environments / TEEs (e.g. Intel SGX). It ensures the user data is processed in privacy-enhancing technologies. With a combination of remote proof, identity authentication, session key exchange and data encryption, users can be guaranteed that the execution environment is expected. Then, a TEE node can process user's data and produce the TEE attestation, which can be verified by the verification layer to make sure the execution result posted on-chain is computed in the same trusted environment where users have submitted their data.
