The Green Code Protocol separates visionary policy from deployable engineering. This matrix provides regulatory and utility partners with an honest assessment of technology maturity — stripping away marketing language to reveal operational realities.
The SYNC architecture interfaces with federal and municipal infrastructure systems. FIPS standards govern cryptographic modules, data integrity verification, and secure communication across every ZKP telemetry node and hardware attestation stack.
Governs the hardware security modules (HSMs) used in the TPM 2.0 attestation stack. All SYNC telemetry signing keys and ZKP proof generation operate within FIPS 140-3 Level 2+ validated boundaries.
SHA-256 and SHA-3 hashing for all energy ledger entries and ZKP commitment schemes. Required for audit trail immutability across municipal water and thermal telemetry data streams.
ECDSA P-256 and EdDSA signatures for all ZKP proof submissions and inter-node telemetry packets. Required for any SYNC node interfacing with federal water authority systems or DoD-adjacent infrastructure.
AES-256-GCM encryption for all data at rest and in transit within the SYNC telemetry pipeline. Covers sensor readings, energy flow data, and ZLD water consumption logs stored in the operational ledger.
Zero Trust principles govern SYNC node onboarding and SCADA system integration. Every node must attest hardware identity via TPM 2.0 before receiving telemetry write access — no implicit trust by network position.
Deterministic Random Bit Generator (CTR_DRBG / AES-256) for ZKP randomness generation. Required to prevent entropy attacks on proof generation in low-entropy edge ASIC environments.

Auditor note: FIPS compliance is not a retroactive bolt-on. The SYNC v2.1 architecture was designed from first principles with FIPS 140-3 as the cryptographic baseline. Items marked Required represent integrations that become mandatory at the point of federal utility contract execution — not gaps in the current protocol. Items marked Planned are on the 12-month development roadmap and are blocked only by SCADA vendor API access, not by engineering feasibility.
