😱 The Problem

Alice and Bob: Lightning channel with 1 BTC
Current state: Alice = 0.7 BTC, Bob = 0.3 BTC
Old state:     Alice = 0.3 BTC, Bob = 0.7 BTC

Bob goes offline → Alice broadcasts OLD state → Steals 0.4 BTC!

✅ The Solution

Bob registers with our watchtower
↓
Watchtower monitors EVERY block 24/7
↓
Alice broadcasts old state → CAUGHT!
↓
Watchtower broadcasts penalty TX → Alice loses ALL her funds (1 BTC → Bob)
↓
Bob is protected even while offline 🔐

🔍 How Breach Detection Works

1. Client sends encrypted hint:
   { hint: first_16_bytes(revoked_txid), encrypted_blob: justice_tx }

2. New block arrives (ZMQ) ──> Check every TX

3. TX matches hint? 🔍
   ├── YES → Decrypt blob → Get justice TX → Broadcast → Funds recovered ✅
   └── NO  → Continue monitoring...

4. Notify client of breach + penalty
