Audit Spine

Court-grade tamper evidence for every act of government.

Inside Audit Spine

A hash-chained, append-only audit log across all branches: per-entity chains, daily checkpoints, and optional OpenTimestamps anchoring to Bitcoin. Vendor-free tamper evidence — the proof does not depend on trusting Segal Industries, the ministry of ICT, or anyone else.

VER-CLR0871MQClearance CLR-2026-0871 authentic — no record

Any state-issued artifact — receipt, permit, clearance, gazette page — verifies at /verify against its ingest hash. Rendered from the demo's seeded world — fictional data.

Everything this module does

The full capability set — nothing hidden behind a toggle.

Hash-chained event log: Every act — docket entry, permit approval, vote, disbursement — appends an event whose hash covers the previous hash and the canonical payload. Alter history and every subsequent hash breaks.
Per-entity chains: Each case, permit, bill, and contract carries its own sub-chain, so a single record's integrity can be proven without replaying the whole state's history.
Daily checkpoints: A daily digest of the global chain is computed and stored redundantly — the anchor point for external verification.
OpenTimestamps anchoring: Optionally, daily checkpoints are anchored to the Bitcoin blockchain via OpenTimestamps: independent, vendor-free existence proofs a court can verify decades later.
Verification tooling: One-click chain verification for auditors; exportable proofs for litigation; a public verification endpoint for artifact hashes.
Anomaly surfacing: Sequence gaps, clock skews, and replay attempts surface to security dashboards in Insight.

How it connects to other offices

Typed, receipted, audited messages move between suites — no folders lost between agencies.
