QBridge’s architecture is modular, compliant, and resilient — built to satisfy both institutional demands and on-chain composability. It consists of five key components working together to enable secu
🧱 Core Components
🔐 1. Quantum-Secure Bridge Nodes
Validators operate using post-quantum signature schemes (e.g., Dilithium, Kyber). These nodes:
Verify cross-chain transactions
Sign metadata packets with quantum-resistant signatures
Participate in consensus for compliance enforcement
💡 Think of them as the secure validators of RWA movement, not just token flows.
⚖️ 2. RWA Policy Engine
This is the on-chain programmable logic that governs:
KYC / AML enforcement
Jurisdiction rules
Whitelist/blacklist rules
Role-based access to asset transfer
📎 Example policy logic:
solidityCopyEditrequire(isWhitelisted(msg.sender)&&isJurisdictionAllowed(msg.sender, destinationChain),"Transfer not permitted");
🧾 3. zkLedger Audit Trail
Every event (lock, mint, burn, release) is recorded on a zero-knowledge ledger:
Aggregated data per chain, per asset, per transfer type
Auditor view is opt-in and privacy-preserving
Compliant with GDPR, MiCA, HKPDPO
🔍 This makes QBridge the only bridge with regulator-grade visibility + user privacy.
🧠 4. AI Verification Oracle
This oracle:
Assesses counterparty risks
Validates identity attestations
Scores the legality of transfer requests
🧠 Machine learning ensures dynamic compliance adaptation across regions.
🧪 Example: If sanctions or laws change in a jurisdiction, the oracle flags and halts illegal transfers immediately.
