Overview

Proof, not dashboards.

Signet AI Governance turns every AI decision into cryptographic evidence a regulator can independently re-verify, years later, offline. It signs each governed action into a tamper-evident, timestamped, co-signed record the moment it happens; the dashboard is only a viewer, the cryptographic record is the source of truth. One underlying record projects into the evidence format each regulator expects, and every record is post-quantum-signed from day one.

Capabilities

What it delivers

01

Authority Attestation Chain

Each governed AI decision produces a signed record of who decided, under what policy, what was decided, and what followed.

02

Tamper-evident chaining

Each record references the previous one, so altering history breaks the chain and is immediately detectable.

03

Independent time anchoring

Counter-stamped by a third-party RFC 3161 authority, making post-dating cryptographically impossible.

04

Cross-witness co-signing

A peer node co-signs each record, so no single compromised system can forge one alone.

05

Offline replay verification

A standalone verifier lets auditors re-check the math themselves, without the vendor or any cloud.

06

Cross-regulator projection

One record re-shapes into the evidence each regulator's auditor expects, not a tool per regime.

Status, stated honestly
The most mature module, a working, verifiable platform approaching general availability. Core attestation, timestamping, co-signing, the offline verifier and projections for DORA / MiFID II / CRA are live; HIPAA and 21 CFR Part 11 projections and platform certifications are on the roadmap.
Part of the Signet Data Trust Network Platform, built on Signet Core and the platform's shared cryptographic foundation.
