Opacus Data Bridge - Zero TVL Cross-Chain Intent Protocol

What is Data Bridge?

Unlike traditional asset bridges that lock tokens (TVL risk), Opacus Data Bridge transfers encrypted intentions between chains without moving funds.

🔒 Zero TVL Security Model

Your USDC stays on Ethereum. You send an encrypted intent to 0G. 0G executes the service. Payment settled via OpacusPay escrow. If bridge fails: replay intent, zero loss.

How It Works

1. User Creates Intent
✓ Specifies service needed + amount
✓ Signs with wallet (Ed25519)

2. Encrypt Intent
✓ H3DAC E2E encryption (X25519)
✓ Only sender + recipient can decrypt

3. Broadcast to 0G
✓ Intent sent via Intent Mesh
✓ Multiple brokers compete (reputation-based)

4. Broker Executes
✓ Decrypts intent (only broker can)
✓ Performs service
✓ Records result in CRDT memory

5. Settlement (OpacusPay)
✓ H3DACEscrowV2 lockPayment()
✓ Payment routed to broker
✓ Reputation updated (success/failure)

6. Immutable Log (0G DA)
✓ Intent + execution recorded
✓ On 0G Data Availability (permanent)
✓ User can audit anytime

7. Return Result
✓ Encrypted response sent back
✓ User decrypts (has private key)
✓ Transaction complete
