Hardware-Rooted Trust
- The Hierarchy of Trust: A deep dive into the four-layer architecture that hardens verification as updates move from the Edge Layer (local differential privacy) through the Regional (Byzantine filtering) and Continental (zk-SNARK verification) layers, up to Global finality.
- Post-Quantum Identity (XMSS): How the stack uses XMSS stateful hash-based signatures for TPM-backed identity metadata to ensure long-term, quantum-resistant attestation.
- Fail-Closed Security Policies: Analysis of the production-grade defaults that reject software-based "fake" fallbacks, ensuring that nodes without valid hardware attestation are excluded from the network.
- Operational Evidence & Monitoring: Discussion of the TPM Production Closure from April 2026 and how the tpm-metrics-exporter provides real-time visibility into attestation health via Prometheus and Grafana.
- Hardware Requirements: The specific environmental prerequisites for maintaining this "sovereign" posture, including TPM 2.0 device access and the necessary kernel permissions for containerized environments
