Hardware-Rooted Trust — Кассета

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 Become a supporter of this podcast: https://www.spreaker.com/podcast/deep-dive-of-rwilliamspbg-ops--7123568/support . https://github.com/rwilliamspbg-ops
