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
