# 🚀 START HERE - Oracle Service Setup Complete

## ✅ What's Been Implemented

Your oracle is now a **fully independent API service** - exactly as you wanted!

```
Employee → POSTs to Oracle API → Oracle verifies → Oracle signs → Blockchain
          ✅ No shared keys     ✅ Independent    ✅ Proper architecture
```

---

## 🧪 Tests Passed

All oracle API endpoints are working:
- ✅ Health check
- ✅ Oracle pubkey retrieval
- ✅ Vault status queries
- ✅ Python client integration

Run tests anytime: `python3 test_oracle.py`

## 🎯 Quick Start (3 Steps)

### 1. Start Oracle Service

```bash
python3 oracle_service/app.py
```

You'll see:
```
🔮 KAPTURE ORACLE SERVICE
══════════════════════════════════════════════════════════════════════

✅ Oracle Public Key: 3fRGj4mzWot9Vmdb6Asxk692WZkhQybU8oNme1MjkYVJ

📡 Starting API server on port 5001...
   URL: http://localhost:5001
```

**Keep this running** - leave terminal open.

**Note:** Port 5001 is used because macOS AirPlay uses 5000.

### 2. Test It Works

In another terminal:
```bash
curl http://localhost:5001/health
```

Should return:
```json
{
  "status": "healthy",
  "oracle_pubkey": "3fRGj4mzWot9Vmdb...",
  "timestamp": "2025-10-27..."
}
```

### 3. Use It

```bash
# Create vault as employer
loggerheads
# Choose: Employer

# Setup as employee
loggerheads
# Choose: Employee

# Start tracking work
loggerheads start

# Submit hours (automatic or manual)
loggerheads submit
```

## 🌐 For Your 3 Testers

### If Testing on Same Network

**You (System Operator):**
1. Find your IP: `ipconfig getifaddr en0` (macOS) or `hostname -I` (Linux)
2. Start oracle: `python3 oracle_service/app.py`
3. Share your IP with testers (e.g., `192.168.1.100`)

**Each Tester:**
```bash
export KAPTURE_ORACLE_URL=http://192.168.1.100:5001

# Make it permanent
echo 'export KAPTURE_ORACLE_URL=http://192.168.1.100:5001' >> ~/.bashrc
```

Then use normally: `loggerheads`

### If Testing Remotely

Use ngrok or deploy to cloud. See `oracle_service/README.md` for deployment options.

## 🔑 Key Concepts

### Oracle = Independent Service

The oracle is **not** controlled by employee or employer:

```
❌ BAD (Old Way):
   Employee has oracle keypair → Can fake hours

✅ GOOD (New Way):
   Oracle API has keypair → Employees POST work → Oracle verifies → Oracle signs
```

### Security Model

- **Employee:** Has wallet keypair, POSTs to oracle API
- **Employer:** Has wallet keypair, creates vaults with oracle pubkey
- **Oracle:** Has oracle keypair (secure on server), signs verified work
- **Smart Contract:** Checks oracle signature, enforces payment rules

### Trust Relationships

- Employee trusts oracle to verify work fairly
- Employer trusts oracle to prevent fraud
- Oracle is independent from both
- Smart contract is trustless (code is law)

---

## 🧩 How It All Works

### 1. Vault Creation (Employer)

```bash
loggerheads
# Choose: Employer
```

**What happens:**
1. Client connects to oracle API
2. Gets oracle public key
3. Creates vault with that oracle
4. Smart contract stores oracle pubkey
5. Only that oracle can submit hours

### 2. Employee Setup

```bash
loggerheads
# Choose: Employee
```

**What happens:**
1. Enter employer's wallet address
2. System derives vault PDA automatically
3. Configures auto-submit (optional)
4. Ready to track work!

### 3. Work Tracking

```bash
loggerheads start
```

**What happens:**
- Screenshots every few minutes
- OCR extracts text
- Stores in local SQLite database
- No blockchain interaction yet

### 4. Submission (End of Day)

```bash
loggerheads submit
# Or automatic via cron at 18:00
```

**What happens:**
1. Client calculates hours from database
2. Client packages work proof (screenshot count, timestamps)
3. Client POSTs to oracle API: `/submit-hours`
4. Oracle verifies vault exists
5. Oracle checks it's the trusted oracle
6. Oracle signs transaction with its keypair
7. Oracle submits to Solana blockchain
8. Smart contract validates oracle signature
9. Smart contract unlocks payment if quota met
10. Client receives transaction signature

### 5. Withdrawal

```bash
loggerheads withdraw
```

**What happens:**
1. Employee signs withdraw transaction
2. Smart contract transfers unlocked USDC
3. Funds arrive in employee's wallet

## ✨ Benefits of This Architecture

### Proper Oracle Pattern ✅
- Matches real blockchain oracles (Chainlink, Pyth)
- Oracle is truly independent
- Production-ready

### Security ✅
- Oracle keypair stays on secure server
- Employees can't fake hours
- Employers can't deny payment

### Scalability ✅
- One oracle serves unlimited vaults
- Easy to add redundancy
- Can run multiple oracle nodes

### UX ✅
- Simple for users (just URL)
- No keypair management
- Clear error messages

## 🚨 Common Issues

### "Cannot reach oracle service"

**Solution:**
```bash
# Check oracle is running
curl http://localhost:5001/health

# Check firewall (if remote)
sudo ufw allow 5001  # Linux
# macOS: System Preferences → Security & Privacy → Firewall
```

### "Port already in use"

**Solution:**
```bash
# Find what's using port 5001
lsof -i :5001

# Kill it
kill -9 <PID>

# Or use different port
export PORT=5002
python3 oracle_service/app.py
```

### "Vault trusts different oracle"

**Solution:**
- Vault was created with different oracle
- Delete and recreate vault with current oracle
- Or connect to correct oracle
