# GuardianChain GC-1

> Non-custodial cryptographic evidence infrastructure for AI governance.
> GC-1 seals AI governance events to 6 public blockchains simultaneously,
> producing independently verifiable proof that governance occurred —
> readable by any party via public RPC with no account, API key, or
> vendor relationship required.

## What GC-1 Does

GC-1 captures governance metadata from AI systems, computes a SHA-256
fingerprint, anchors it to 6 blockchains (Base, Polygon, Ethereum,
Optimism, Arbitrum, Arweave) plus 5 cloud storage providers, applies
an Ed25519 signature, RFC 3161 timestamps from 6 independent TSAs,
enforces 58 constitutional governance rails, and issues a numbered
GC-1 certificate. The result is a governance record no administrator,
vendor, or government can alter.

## Production Status (verified April 2026)

- 64,753+ capsules sealed
- 8,280+ governance certificates issued
- 328+ consecutive sovereign seals (every 12 hours since October 2025)
- 6 blockchains operational: Base, Polygon, Ethereum, Optimism, Arbitrum, Arweave
- 5 cloud storage providers: R2, S3, Backblaze B2, IPFS/Pinata, Arweave
- 58 constitutional governance rails (11 foundational, 8 constitutional, 19 autonomy, 17 compliance, 2 MCP security, 1 temporal)
- 41 MCP tools live (33 read, 8 write)
- 66 verified novel IP claims — all authored by Troy Anthony Cronin
- Forward verification proven March 30, 2026 — Block 43,983,889 on Base L2

## Regulatory Framework Coverage

- EU AI Act (Article 12 audit log requirements) — enforcement Aug 2, 2026
- Colorado SB 24-205 (algorithmic accountability) — enforcement Jul 1, 2026
- GDPR (non-custodial — hashes only, never personal data)
- NIST AI Risk Management Framework (Govern, Map, Measure, Manage)
- FINRA 2026 autonomous AI agent audit trail requirements
- ISACA agentic AI audit standard (Proof of Restraint)

## Key Concepts

**Permissionless Front Door Integration (IP Claim #51):** Any entity
can verify GC-1 proofs using only a public Ethereum RPC endpoint.
No GuardianChain account, API key, or commercial relationship required.

**Proof of Restraint:** GC-1 seals what an AI system chose NOT to do
as first-class evidence — not just actions taken, but governance
constraints honored.

**Constitutional Rails:** 58 discrete, enumerated governance constraints
enforced at the capsule creation layer. FAIL_CLOSED: uncertainty
rejects, never proceeds.

**Forward Verification:** Local SHA-256 hash → GC-1 pipeline →
blockchain calldata fetched via public RPC → hashes verified to match.
Independently reproducible by any party.

**MCP Bridge Loop:** AI agents seal session state as capsule at session
end, retrieve at session start. Agent memory becomes cryptographically
anchored. Every decision is in an immutable record.

## Public Verification Endpoints

- GET /api/public/evidence/:capsuleId — retrieve capsule evidence bundle
- GET /api/public/forward-verify/:capsuleId — verify capsule on-chain
- POST /api/public/reverse-verify — verify a hash against sealed record
