Trust & Compliance

Rapha Protocol trust and compliance architecture. The system turns compliance intent into enforceable deployment controls: OPA policy gate enforces institutional rules before computation, SGX enclave provides hardware-backed confidential execution, Sigstore-signed supply chain verification ensures workload integrity, Rust air-gap kernel module enforces network isolation during training, and ZK-TLS cryptographic audit receipts provide verifiable execution trails.

Architectural posture, not a legal certification. The protocol is designed around HIPAA Security Rule controls, NHS DSPT standards, and GDPR data minimization principles — but does not claim formal compliance. Production deployment requires institutional review, signed BAAs/DPAs, and independent security assessment.
