### Cryptographic Primitives (`lib/crypto/`)## 🧠 Developer Implementation Pattern

```javascript

// Canonical ECDSA operations### A. Data Structures

bsv.crypto.sign(data, privateKeyWIF)           // → string (hex)

bsv.crypto.verify(data, signature, publicKey)  // → boolean```ts

interface LegalToken {

// Shamir Secret Sharing  issuerDid: string;

bsv.crypto.createShares(secret, n, k)          // → string[]  subjectDid: string;

bsv.crypto.reconstructSecret(shares)           // → string  claim: Record<string, any>;

bsv.crypto.verifyShares(shares)                // → boolean  jurisdiction: string;

  purpose: string;

// Hash and commitment utilities  proof: string;        // DER sig or JWS

bsv.crypto.hash(data, algorithm)               // → string  anchorTxid: string;   // optional on-chain record

bsv.crypto.hmac(data, key)                     // → string}

bsv.crypto.commit(obj, key)                    // → string (GDPR-safe)```

```

### B. Minimal Functions

### Legal Token Protocol (`lib/ltp/`)

```javascript```js

// Right token primitivesbsv.LTP.createRightToken = function(type, subjectDid, claim, issuerWIF) {...}

bsv.prepareRightToken(type, issuerDID, subjectDID, claim, privateKey, options)bsv.LTP.verifyRightToken = function(token) {...}

bsv.prepareRightTokenVerification(token, options)bsv.LTP.anchorRightToken = function(token) {...}

bsv.prepareRightTokenTransfer(token, newOwnerDID, currentOwnerKey, options)bsv.LTP.revokeRightToken = function(tokenId) {...}

```

// Obligation token primitives

bsv.prepareObligationToken(type, issuerDID, obligorDID, obligation, privateKey, options)Internally these reuse:

bsv.prepareObligationVerification(token, options)

bsv.prepareObligationFulfillment(token, fulfillment, obligorKey, options)* `bsv.crypto.ECDSA` and `SmartVerify`

* `bsv.crypto.HMAC` for commitments

// Claim validation primitives* `bsv.Transaction` for anchor Tx

bsv.prepareClaimValidation(claim, schemaName)* `bsv.GDAF` for DID resolution & VC schema validation

bsv.prepareClaimAttestation(claim, schemaName, attestor)

```

* **Never put PII on-chain** — anchor only HMAC commitments.

---* **Per-purpose keys:** `commit = HMAC(k_subject_purpose, canonicalJSON)`.

* **Revocation registries**: store off-chain, hash-anchor the list.

## 📋 Standards Compliance* **Roles:**

| Framework         | Relationship                                           |

## 🛠️ Implementation Guidelines| ----------------- | ------------------------------------------------------ |

| **GDAF**          | LTP extends GDAF VC model with legal semantics.        |

### Development Principles| **NotaryHash**    | Anchoring service for commitments / revocation.        |

1. **Backward Compatibility** - All existing APIs remain functional| **Web3Keys**      | Source of DIDs and public key verification.            |

2. **Modular Architecture** - Independent module loading and usage| **SmartContract** | Execution engine for conditional rights / obligations. |

3. **Cross-Platform Support** - Node.js, browser, and embedded systems

4. **Deterministic Operations** - Reproducible builds and consistent outputs---

5. **Security First** - Hardened cryptographic implementations

## 🧩 Example Flow

### Integration Patterns

```javascript```js

// External Application Integration Example// 1.  Create Right

const bsv = require('smartledger-bsv')const claim = { assetId: "VIN1234", owner: "did:smartledger:greg" };

const MyBlockchainAPI = require('my-blockchain-service')const token = bsv.LTP.createRightToken("VehicleTitle", "did:smartledger:greg", claim, issuerWIF);

const MyStorage = require('my-database-service')

// 2.  Anchor commitment

// 1. Use SmartLedger-BSV to prepare legal tokenawait bsv.LTP.anchorRightToken(token);

const tokenPrep = bsv.prepareRightToken(/* parameters */)

// 3.  Verify later

// 2. Use external service to publish to blockchainconst valid = bsv.LTP.verifyRightToken(token);

const txResult = await MyBlockchainAPI.publish(tokenPrep.commitment)console.log("Token valid:", valid);

```

// 3. Use external service to store token data

const storeResult = await MyStorage.save(tokenPrep.token)---



// 4. Use SmartLedger-BSV to verify results## 🚀 Next Milestones

const verification = bsv.verifyTokenAnchor(token, txResult.txid)

```1. Implement `/lib/ltp/` core modules.

2. Integrate with `bsv.GDAF` schemas and `bsv.NotaryHash`.

### Testing Requirements3. Add CLI: `smartledger ltp issue right.json --anchor`.

- **Unit Tests** - All primitive functions must have 100% test coverage4. Publish spec as `@smartledger/ltp` for external adopters.

- **Integration Tests** - End-to-end workflows with real BSV transactions5. Pilot with KYC + Property Rights programs (Africa, Regulators).

- **Compliance Tests** - Validation against W3C and legal standards

- **Security Tests** - Cryptographic validation and vulnerability assessment---

Excellent — that’s the right move.

## 7️⃣ Governance & Compliance Layer

**Purpose:**
Ensure trust, accountability, and global legal interoperability.

**Structures:**

* SmartLedger Foundation → Root Trust Anchor & Namespace Authority.
* Regional / national identity issuers (via delegated DIDs).
* Schema Registry (Credential & Legal Token types).
* Compliance Registry (GDPR / FATF / eIDAS alignment).
* Public Audit API (anchor & revocation visibility).

**Standards Alignment:**

* W3C DID & VC 2.0
* ISO/IEC 18013-5 (mobile ID)
* eIDAS2 (EU legal recognition)
* FATF Travel Rule (financial KYC)
* GDPR / CCPA (privacy by design)

---

## 8️⃣ Technical Flow (End-to-End Example)

```
1. User registers via Web3Keys → DID created (did:smartledger:xyz)
2. GDAF provides EmailVerifiedCredential template and signing
3. LTP wraps it as KYCVerifiedLegalToken (attestation of identity)
4. NotaryHash prepares rootHash commitment for external anchoring
5. SmartLedger-BSV provides signature verification + SmartVerify
6. User presents credential via ZK proof (e.g., prove over 21)
7. Regulator or service verifies off-chain proof + queries external anchor
8. Transaction or service executes (TicketMint, SmarterBond, etc.)
```

All layers are **modular** — any third party can adopt one or all:

* Identity only (GDAF)
* Legal rights only (LTP)
* Full-stack attestation (GDAF + LTP + NotaryHash)

# **SmartLedger-BSV — The Foundational Layer of the Lawful Web3**

### *A Universal, Legally-Anchored, Cryptographically Verifiable Framework for Identity, Contract, and Property Rights*

---

## 🧭 **Mission**

> To provide humanity with a universal, legally-anchored, cryptographically verifiable framework for **identity**, **contracts**, and **property** —
> built on the **immutable timestamp ledger**, using **hardened open standards**, not corporate control.

SmartLedger-BSV exists to ensure that **Web3 and Law** converge into a single, auditable digital fabric —
one that outlives its creators and empowers generations to inherit enforceable, recoverable, and sovereign rights.

---

## 1️⃣ **The Role of SmartLedger-BSV**

SmartLedger-BSV is the **primitive foundation layer** —
a **hardened, modular, cross-platform** library providing the cryptographic and legal primitives required for interoperable Web3 infrastructure.

It is **not an application framework or blockchain publisher**.
It is the **bedrock toolkit** upon which:

* Developers build decentralized systems with proper cryptographic foundations;
* Governments implement verifiable credential issuance systems;
* Banks and institutions encode enforceable digital contracts with legal recognition;
* Artists, inventors, and families secure property and legacy with recoverable keys.

Think of it as the **"OpenSSL + Legal Standards of Web3."**

---

## 2️⃣ **Core Responsibilities**

| **Domain**            | **Capability**                                                                                | **Purpose**                                                   |
| --------------------- | --------------------------------------------------------------------------------------------- | ------------------------------------------------------------- |
| **Cryptography**      | Hardened `bsv@1.5.6` with canonical signatures, malleability protection, elliptic curve fixes | Secure, deterministic signing and verification primitives     |
| **Key Management**    | Shamir Secret Sharing, recovery flows, multi-signature orchestration                          | Durable, inter-generational key security and recoverability   |
| **Hashing & Proofs**  | Deterministic hashing, HMAC commitments, ZK/Merkle proofs                                     | Immutable attestations with privacy-preserving verification   |
| **Transaction Layer** | `OP_PUSH_TX`, covenant script helpers, SmartContract interpreter                              | Legal & logical transaction construction and validation |
| **Identity (W3C)**    | DID & Verifiable Credential generation and verification primitives                            | Global self-sovereign identity compliance (GDAF integration)  |
| **Legal Token (LTP)** | Templates for property rights, licenses, contracts, and obligations                           | Cross-jurisdictional legal interoperability & recognition     |
| **Anchoring**         | Timestamped commitment formatting and verification utilities                                   | Non-repudiation, accountability, and immutable recordkeeping primitives  |

---

## 3️⃣ **Guiding Principles**

### 🧱 1. **Foundation, Not Control**

SmartLedger-BSV is the **neutral substrate** upon which any lawful Web3 application can stand —
it enforces open standards (W3C, ISO, eIDAS, FATF), not corporate dominance.

### 🔏 2. **Lawful by Design**

The library embeds the core pillars of **jurisprudence** —
**Identity**, **Contract**, and **Property** — directly into its cryptographic logic.
Every object can be tied to a lawful actor (DID), a lawful action (signature), and a lawful record (anchor).

### ♻️ 3. **Interoperable Across Borders**

Designed for regulators, developers, and citizens alike —
it supports **cross-jurisdictional**, **cross-chain**, and **cross-industry** compatibility.

### 🔐 4. **Sovereign Yet Recoverable**

Through **Shamir Secret Sharing**, hierarchical key derivations, and secure backup protocols,
SmartLedger-BSV ensures digital sovereignty with real-world recoverability.

### ⚖️ 5. **Privacy with Proof**

No PII is stored on-chain.
All attestations use **HMAC-scoped commitments** and **zero-knowledge proofs** for verifiable privacy compliance (GDPR, CCPA, etc.).

---

## 5️⃣ **Interoperability Goals**

| **Domain**        | **Standard Alignment**                                       |
| ----------------- | ------------------------------------------------------------ |
| Identity          | W3C DID, VC 2.0, ISO/IEC 29003                               |

| Compliance        | FATF Travel Rule, FINMA KYC                                  |
| Blockchain        | BSV native, cross-chain via OP_RETURN + Merkle root bridging |

The library intentionally remains **protocol-neutral** —
anchoring to BSV by default but abstracted for multi-chain notarization.

---

## 6️⃣ **Developer Interface Overview**

```js
// Identity & Credential
const did = SmartLedgerBSV.GDAF.createDID(publicKey);
const emailVC = SmartLedgerBSV.GDAF.createEmailCredential(issuerDid, subjectDid, email, issuerKey);

// Legal Tokenization
const rightToken = SmartLedgerBSV.LTP.createRightToken('PropertyDeed', subjectDid, claim, issuerKey);

// Anchoring & Proof
const anchorData = SmartLedgerBSV.Anchor.prepareCommit(rightToken.rootHash, { purpose: 'property-right' });
const proof = SmartLedgerBSV.ZK.generateFieldProof(rightToken, 'claim.parcelId');

// Verification
SmartLedgerBSV.LTP.verifyRightToken(rightToken);
SmartLedgerBSV.ZK.verifyFieldProof(proof, rightToken.rootHash);
```

---

## 7️⃣ **Why It Matters**

SmartLedger-BSV turns blockchain from **speculative infrastructure** into **civil infrastructure**.

It enables:

* **Governments** to issue verifiable identity and property credentials
* **Businesses** to execute legally binding smart contracts
* **Developers** to build interoperable Web3 apps aligned with real law
* **Individuals** to control, transfer, and recover their digital lives

It is the **trust layer** that ensures a Web3 world can coexist with centuries of law —
bridging *code, contract, and conscience.*

---

## 8️⃣ **Vision for Longevity**

When your great-grandchildren access your music royalties, your trust distributions, or your patents —
SmartLedger-BSV ensures those rights are:

* **Verifiable** (anchored on the immutable ledger)
* **Recoverable** (through Shamir slices and legal key recovery)
* **Recognized** (within both code and law)

That is the **Lawful Web3** — and this library is its foundation.

---Perfect — this will be the **SmartLedger-BSV Technical Specification v1.0**, the canonical developer and standards reference that defines *how the Lawful Web3 foundation is implemented in code*.

This spec will be structured like a standards document (W3C/ISO-style) — concise, precise, and future-proof.
It defines module boundaries, key responsibilities, and implementation requirements.
