The QBridge Solution

QBridge isn’t a bridge — it’s a full-stack infrastructure layer for transferring regulated RWAs securely across chains, jurisdictions, and time. Each component is purpose-built for capital-grade token

🔐 1. Post-Quantum Cryptography Core

QBridge uses CRYSTALS-Dilithium and Kyber — the post-quantum algorithms approved by NIST — to secure all signature schemes and transport logic.

✳️ This replaces legacy ECDSA systems that quantum computers could break in minutes.

✅ Benefits:

  • Resistant to Shor’s algorithm

  • Safe from nation-state quantum exploits

  • Future-proofed compliance with MiCA, eIDAS, HKMA


🧠 2. AI-Powered Compliance Layer

🔍 “Regulatory logic is not optional — it’s programmable.”

QBridge embeds AI-based engines to enforce:

  • KYC / AML

  • Jurisdictional filtering

  • Investor eligibility

  • Risk scoring (adaptive)

⚙️ How It Works:

  • Smart contracts are injected with on-chain compliance hooks

  • AI models score counterparties before bridging

  • Policies adapt in real-time based on identity, region, and asset class

📎 Example: An RWA token can’t be bridged to a U.S. investor if restricted under local laws.


🔗 3. Cross-Chain RWA Messaging Protocol

This is not just token movement — it’s asset transfer with legal memory.

✅ QBridge transfers:

  • Ownership rights

  • Legal jurisdiction tags

  • Oracle-bound valuations

  • Identity-linked metadata

🧬 Built for standards like ERC-3643, SPL-RWA, and security token protocols.

📦 Example Payload:

jsonCopyEdit{
  "token_id": "RWA-113A",
  "legal_terms": "Bond Class B, 7.3% yield",
  "jurisdiction": "SG",
  "oracle_price": 101.32
}

🧾 4. Auditable zkLedger Transport Layer

All bridge events — lock, mint, burn, release — are logged in a zero-knowledge ledger (zkLedger).

Benefits:

  • Full audit trails without leaking PII

  • Third-party regulators can access logs with user opt-in

  • GDPR/HKPDPO compliant by design

🔍 Auditors get traceability. Users keep privacy.
