Problem Statement

🧩 1. RWA Tokenization Is Fragmented

The current state of tokenized real-world assets (RWAs) is siloed:

• Treasuries on Ethereum

• Carbon credits on Solana

• Real estate on Polygon

• Equity shares on private subnets

This chain fragmentation breaks liquidity, interoperability, and legal continuity.

🔍 There is no unified protocol to legally and technically transfer regulated RWAs across ecosystems.

🔓 2. Bridges Aren’t Built for Compliance

Most cross-chain protocols:

• Treat tokens as generic fungibles

• Can’t handle jurisdictional rules

• Don’t enforce whitelists, caps, or legal terms

🔐 You can’t bridge a tokenized security the same way you bridge a meme coin.

Without compliance:

• Institutions can’t use the rails

• Regulated assets can't scale

• Transfers become legally void across jurisdictions

⚠️ 3. Traditional Cryptography Is Becoming Obsolete

Algorithm	Risk Under Quantum Computing
RSA	Broken by Shor’s algorithm
ECDSA	Vulnerable to quantum attack
AES-128	At risk from Grover’s speedup

🧬 Bridges using today’s cryptographic standards are vulnerable to tomorrow’s quantum threats.

QBridge is built using NIST-approved post-quantum cryptography from the ground up — not as a patch.

🛠 QBridge is built to solve this:

• ✅ Unifies fragmented RWA ecosystems

• ✅ Enforces legal compliance programmatically

• ✅ Uses quantum-resistant infrastructure
