Trust Layer = what you do. Health Layer = how you sustain it. Coherence ID = who you are.
The Three-Layer Architecture
| Layer | Function | Interface |
|---|---|---|
| Layer 1 · Trust | Economic reliability — Trust Score, commitments, badges | Public QR + Public Profile |
| Layer 2 · Social Health | Human vitality — HRV, work-rest, sustainability | Opt-in QR + Private Profile |
| Layer 3 · Coherence ID | Sovereign identity — DID + quantum encryption + QR | Unified QR System |
Coherence ID Specification
| Attribute | Specification |
|---|---|
| Underlying Standard | W3C DIDs + Verifiable Credentials |
| Cryptography | Post-Quantum — ML-DSA (signatures), ML-KEM (key exchange) |
| Storage | Decentralized — user holds the private key; public DID document on a ledger |
| Binding | Anchored to the Trust Ledger and (opt-in) Health Layer |
Layer 1 · The Public Trust Profile
Publicly visible economic reputation. Anyone can look up your Coherence ID and instantly see verifiable reliability — no "trust me," no fake reviews.
| Data Point | Source | Visibility |
|---|---|---|
| Legal Name / DBA | Verified credential (gov registration) | Public |
| Trust Score | Trust Ledger (Honored / Issued) | Public |
| Coherence Score | Coherence Widget scans | Public |
| Verification Badges | Security audit, SME completion | Public |
| Commitment Log | Active commitments + verification links | Public |
Layer 2 · The Private Vitality Profile
Private and opt-in. The Hub stores no raw HRV — it stores an encrypted zero-knowledge proof of your vitality status.
| Data Point | Source | Visibility |
|---|---|---|
| HRV Score | Wearable (Oura, Apple Watch, Whoop) | Opt-in only |
| Work-Rest Ratio | Calendar + HRV aggregation | Opt-in only |
| Stress Indicators | HRV trends, sleep, recovery | Opt-in only |
| Social Health Score | Team sync metrics (anonymized) | Opt-in only |
| Capacity Forecast | AI-predicted sustainable output (7 days) | Opt-in only |
The Business Opt-In Model
Granularity controlled by the user — not the platform.
| Relationship | Trust Layer | Health Layer |
|---|---|---|
| Public (Anyone) | Full Trust Score, Commitment Log, Badges | None — private by default |
| Partners (Approved) | Full Trust Layer + Credentials | Team-level HRV aggregates |
| Investors (Due Diligence) | Trust Layer + Audit Trails | Sustainability risk score (anonymized) |
| Coaches / Advisors | Trust Layer (context) | Full HRV + Work-Rest + Stress |
| The Hub (algorithms) | Full Layer 1 | Anonymized Layer 2 for network insights |
The Quantum Encryption Argument
| Threat | Solution |
|---|---|
| Intercepted DID | ML-KEM keeps the channel quantum-safe |
| Forged signature | ML-DSA cannot be forged even by a quantum computer |
| Ledger breach | DID document is public by design; private keys stay with the user |
| Long-term data theft | PQC is future-proof — stolen ciphertext stays unreadable |
Your Coherence ID is valid today and remains valid 10 years from now, even as computing power scales.
The Coherence Wallet (UX)
| Feature | Description |
|---|---|
| ID Dashboard | Trust Score, Coherence Score, HRV trend, active commitments |
| Share Control | Toggle what is visible to partners, investors, or the public |
| Issuance | Receive Verifiable Credentials (SME complete, audit passed) |
| Verification | Scan another Coherence ID to verify Trust Score + credentials |
| Recovery | Social or multi-sig recovery — no central authority reset |
The Hub holds no private key. You do. The Hub verifies your public DID document.
Integration with the Container
| Component | How the Coherence ID fits |
|---|---|
| Ontology | Defines identity attribute terms |
| Trust Ledger | All commitments anchor to your ID |
| The Gate | Entry requires a Coherence ID |
| Grant Program | Grantees verified by their ID |
| CET Token | Tokens held at the ID wallet address |
| SME Module | Completion issues a VC to your ID |
| Coherence Search | Results show the verified ID + public Trust Score |
| Social Health Layer | HRV encrypted + linked to your ID |
The Coherence QR System
The visual, scannable representation of a Coherence ID — the bridge between the online container and the offline world.
| Element | Specification |
|---|---|
| Format | ISO/IEC 18004 QR with embedded Coherence ID URI |
| URI Scheme | coherence://id/{did} |
| Payload | Public DID reference + encrypted challenge for opt-in data |
| Security | ML-KEM post-quantum key exchange on scan |
| Binding | Tied to Trust Ledger + opt-in Health Layer |
QR Display Types
| Type | Where it appears | Public | Opt-in |
|---|---|---|---|
| Personal ID | Business cards, signatures, badges | Name, Trust Score, Badges | HRV, Work-Rest, Sustainability |
| Business Listing | Storefronts, packaging, websites | Business, Trust, Coherence, Commitments | Team HRV aggregate, Stress |
| Event Badge | Conferences, meetups | Name, Trust Score, Badges | Meeting HRV sync, Energy forecast |
| Invoice / Contract | Billing, agreements | Business, Trust, Commitment Log | Sustainability risk score |
| Product | Physical packaging | Manufacturer, Trust, Badges | Supply chain HRV (optional) |
QR Encryption Flow
The QR holds only a public DID reference — no private keys, no health data. Opt-in data travels over a post-quantum channel.
| Step | Action | Encryption |
|---|---|---|
| 1 | Scanner reads QR, fetches DID document | Public (unencrypted) |
| 2 | Opt-in requested → scanner opens secure channel | ML-KEM key exchange |
| 3 | ID holder receives request and grants access | Encrypted with holder public key |
| 4 | Data shared | Signed with ML-DSA |
QR Privacy & Consent Policy
Consent First
Health data never shared without explicit, granular opt-in
Transparency
Scanner sees exactly what is requested and why
Granularity
Different data for different parties
Revocation
Access revoked at any time; encrypted channel expires
Auditability
All sharing logged for the user (not public)
Strategic Advantage
| Competitor | QR | Trust Layer | Health Layer |
|---|---|---|---|
| LinkedIn QR | Yes | No | No |
| WeChat QR | Yes | No | No |
| Worldcoin | Yes | No | No (centralized) |
| Coherence QR | Yes | Yes (Trust Score) | Yes (HRV opt-in) |
Your Coherence Wallet
A real ECDSA P-256 keypair generated in your browser. You hold the private key — no server stores it. Post-quantum (ML-DSA / ML-KEM) remains the roadmap; today this is real, verifiable cryptography.

}The Pitch
"We are building a verification layer for economic relationships. A Coherence ID is a self-held, quantum-resistant identity that carries a Trust Score and, if the holder opts in, an encrypted vitality score.
The ID is public for trust, private for health, and independently verifiable. It replaces unverifiable reputation signals — paid reviews, self-reported reliability — with a logged, checkable commitment record.
A single identity that answers two operational questions: Can I depend on you? And can you sustain it? The specification is complete; the reference implementation is in progress."
The specification is complete. The ID is self-held. The QR is the physical interface. Trust is verifiable. Health data is opt-in.
