Analogy

Secure enclave contracts are like secret meeting rooms where discussions are hidden from everyone outside.

Definition

Privacy-preserving smart contracts executed within Trusted Environments (TEEs), encrypting inputs, outputs, and to protect confidentiality.

Key Points Intro

Secure enclave contracts combine verification with TEE confidentiality.

Key Points

Confidentiality: code and data remain encrypted outside TEEs

Attestation: remote proof of correct code execution

Off-chain compute: heavy processing occurs within TEEs

Hybrid model: on-chain logic enforces state transitions

Example

Secret Network runs smart contracts inside enclaves, keeping user data private while publicly verifying integrity.

Technical Deep Dive

Contracts deploy encrypted ; TEE nodes fetch, decrypt, and execute code, then generate proofs. layers verify attestations and commit encrypted updates. Enigma uses MPC instead of TEEs for enhanced .

Security Warning

TEEs have known vulnerabilities (e.g., Spectre, Meltdown) and rely on hardware vendor trust.

Caveat

Performance overhead and limited TEE availability constrain .
