**Component Communication:**
- **ElectrumX** ↔ **Palladium Node**: RPC over internal Docker network
- **Web Dashboard** ↔ **Palladium Node**: RPC for blockchain data
- **Web Dashboard** ↔ **ElectrumX**: Electrum protocol + Docker API for stats
- **External Clients** → **ElectrumX**: TCP (50001) or SSL (50002)
- **Browsers** → **Web Dashboard**: HTTP (8080)

---

## Requirements

* [Docker](https://docs.docker.com/get-docker/) 20.10+
* [Docker Compose](https://docs.docker.com/compose/install/) 2.0+
* **Palladium binaries** - See installation instructions below

---

## Quick Start Guide

### Step 1: Clone the Repository

```bash
git clone <your-repository-url>
cd palladium-stack
```

---

### Step 2: Get Palladium Binaries

**IMPORTANT:** Download binaries matching your system architecture in `daemon/`. 

See [daemon/README.md](daemon/README.md) for detailed instructions.

---

### Step 3: Configure Network and Router

#### 3.1 Configure RPC Credentials

Open the configuration file:

```bash
nano .palladium/palladium.conf
```

**Change these credentials:**
```conf
rpcuser=your_username     # ← Change this
rpcpassword=your_password # ← Use a strong password!
```

Save and close (`Ctrl+X`, then `Y`, then `Enter`).

#### 3.2 Router Port Forwarding (Required for Public Access)

For your ElectrumX server to be accessible from the internet, you **must** configure port forwarding on your router.

**Ports to Forward:**

| Port | Protocol | Service | Description | Required? |
|------|----------|---------|-------------|-----------|
| **2333** | TCP | Palladium P2P | Node connections | **Yes** (for node sync) |
| **50001** | TCP | ElectrumX TCP | Wallet connections | Recommended |
| **50002** | TCP | ElectrumX SSL | Encrypted wallet connections | **Recommended** |
| **8080** | TCP | Web Dashboard | Monitoring interface | Optional |

**How to Configure Port Forwarding:**

1. **Find Your Internal IP:**
   ```bash
   # Linux/Mac:
   hostname -I

   # Or check in Docker host:
   ip addr show
   ```
   Example: `192.168.1.100`

2. **Access Your Router:**
   - Open browser and go to your router's admin page (usually `192.168.1.1` or `192.168.0.1`)
   - Login with router credentials

3. **Add Port Forwarding Rules:**

   Navigate to **Port Forwarding** or **Virtual Server** section and add:

   ```
   Service Name: Palladium P2P
   External Port: 2333
   Internal Port: 2333
   Internal IP: 192.168.1.100 (your server's IP)
   Protocol: TCP

   Service Name: ElectrumX SSL
   External Port: 50002
   Internal Port: 50002
   Internal IP: 192.168.1.100
   Protocol: TCP

   Service Name: ElectrumX TCP
   External Port: 50001
   Internal Port: 50001
   Internal IP: 192.168.1.100
   Protocol: TCP

   Service Name: PLM Dashboard (optional)
   External Port: 8080
   Internal Port: 8080
   Internal IP: 192.168.1.100
   Protocol: TCP
   ```

4. **Save and Apply** the configuration.

5. **Find Your Public IP:**
   ```bash
   curl ifconfig.me
   ```
   Or visit: https://whatismyipaddress.com

**Security Notes:**
- Only forward port **8080** if you want the dashboard accessible from internet (not recommended without authentication)
- Consider using a VPN for dashboard access instead
- External dashboard clients (public IPs) require Basic Auth. Configure `DASHBOARD_AUTH_USERNAME` and `DASHBOARD_AUTH_PASSWORD` in `.env` (see `.env.example`).
- Ports **50001** and **50002** need to be public for Electrum wallets to connect
- Port **2333** is required for the node to sync with the Palladium network

---

#### 3.3: (Optional) Configure Dashboard Authentication

If you plan to expose the dashboard to the internet (port 8080), configure Basic Auth credentials:

```bash
cp .env.example .env
nano .env
```

Set strong credentials:
```bash
DASHBOARD_AUTH_USERNAME=admin
DASHBOARD_AUTH_PASSWORD=a-strong-random-password
```

LAN clients (private IPs) can access the dashboard without authentication. External clients (public IPs) will be prompted for these credentials automatically.

---

### Step 4: (Optional) Copy Existing Blockchain Data

If you have a synced Palladium blockchain, copy it to speed up initial sync:

```bash
cp -r ~/.palladium/blocks .palladium/
cp -r ~/.palladium/chainstate .palladium/
cp -r ~/.palladium/indexes .palladium/
```

**Skip this** if syncing from scratch - the node will automatically start syncing.

---

### Step 5: Build and Start

```bash
docker compose up -d
```

**What happens:**
1. Builds three Docker images: `palladium-node`, `electrumx-server`, and `palladium-dashboard`
2. Starts Palladium node first
3. Starts ElectrumX (waits for node to be ready, auto-generates SSL certificates in `./certs/` if not present)
4. Starts Web Dashboard (connects to both services)

**First build takes 5-10 minutes.**

---

### Step 6: Monitor Progress

```bash
# View all logs
docker compose logs -f

# View specific service
docker compose logs -f palladiumd
docker compose logs -f electrumx
docker compose logs -f dashboard
```

**What to look for:**
- **Palladium node:** "UpdateTip" messages (syncing blockchain)
- **ElectrumX:** "height X/Y" (indexing blocks)
- **Dashboard:** "Running on http://0.0.0.0:8080"

Press `Ctrl+C` to exit log view (containers keep running).

---

### Step 7: Access Web Dashboard

**Local access:**
```
http://localhost:8080
```

**Network access:**
```
http://<your-server-ip>:8080
```

**From internet (if port 8080 forwarded):**
```
http://<your-public-ip>:8080
```

The dashboard shows:
- System resources (CPU, RAM, Disk)
- Palladium node status (height, difficulty, connections, sync progress)
- ElectrumX server stats (version, active servers, DB size, uptime, **server IP**, ports)
- Mempool information (transactions, size, usage)
- Recent blocks table
- Network peers (click "Connections" to view detailed peer list)
- Electrum active servers page (click "Active Servers")

## Verify Installation

### Check Container Status

```bash
docker compose ps
```

Should show all three containers "Up".

### Test Palladium Node

```bash
docker exec palladium-node palladium-cli \
  -rpcuser=<your_username> \
  -rpcpassword=<your_password> \
  getblockchaininfo
```

### Test ElectrumX Server

```bash
python test-server.py <your-server-ip>:50002
```

### Check from External Network

From another machine:
```bash
# Test dashboard
curl http://<your-public-ip>:8080

# Test ElectrumX (with Python)
python test-server.py <your-public-ip>:50002
```

### REST API Endpoints

The dashboard exposes a REST API for programmatic access:

| Endpoint | Description |
|----------|-------------|
| `GET /api/health` | Service health check (palladium + electrumx status) |
| `GET /api/system/resources` | CPU, memory, and disk usage |
| `GET /api/palladium/info` | Node info (blockchain, network, mining, mempool) |
| `GET /api/palladium/peers` | Detailed peer list with traffic stats |
| `GET /api/palladium/blocks/recent` | Last 10 blocks |
| `GET /api/electrumx/stats` | ElectrumX version, uptime, DB size, active servers |
| `GET /api/electrumx/servers` | Discovered ElectrumX peers with reachability |

```bash
# Example
curl http://localhost:8080/api/health | jq
```

## Configuration Details

### Palladium Node Settings

Key settings in `.palladium/palladium.conf`:

| Setting | Value | Purpose |
|---------|-------|---------|
| `rpcuser` | `<your_username>` | RPC authentication |
| `rpcpassword` | `<your_password>` | RPC authentication |
| `server=1` | Required | Enable RPC server |
| `txindex=1` | Required | Index all transactions (ElectrumX needs this) |
| `addressindex=1` | Recommended | Index addresses for fast queries |
| `timestampindex=1` | Recommended | Index timestamps |
| `spentindex=1` | Recommended | Index spent outputs |
| `rpcbind=0.0.0.0` | Required | Allow Docker connections |
| `rpcallowip=10.0.0.0/8` | Recommended | Allow private RFC1918 networks |
| `rpcallowip=172.16.0.0/12` | Recommended | Allow private RFC1918 networks |
| `rpcallowip=192.168.0.0/16` | Recommended | Allow private RFC1918 networks |
| `port=2333` | Default | P2P network port (mainnet) |
| `rpcport=2332` | Default | RPC port (mainnet) |

**ZeroMQ Ports (optional):**
- `28332` - Block hash notifications
- `28333` - Transaction hash notifications
- `28334` - Raw block data
- `28335` - Raw transaction data

### ElectrumX Settings

Configured in `docker-compose.yml`:

```yaml
environment:
  COIN: "Palladium"        # Always "Palladium" for both networks
  NET: "mainnet"           # or "testnet"
  SERVICES: "tcp://0.0.0.0:50001,ssl://0.0.0.0:50002"
  # RPC credentials automatically read from palladium.conf
```

**Automatic Configuration (via `entrypoint.sh`):**
- **RPC credentials**: Read automatically from mounted `palladium.conf` — no need to configure `DAEMON_URL`
- **Public IP detection**: Discovers your public IP and sets `REPORT_SERVICES` for peer announcement
- **SSL certificates**: Auto-generated on first startup in `./certs/` with SAN including localhost and public IP (see [Security > SSL Certificates](#production-deployment))
- **TX stats patching**: Queries the live node for `TX_COUNT` / `TX_COUNT_HEIGHT` and patches the ElectrumX coin definition at startup
- Single source of truth for credentials across all services

---

## Network Support (Mainnet & Testnet)

### Running on Mainnet (Default)

Default configuration is for **mainnet** - no changes needed.

**Ports:**
- Palladium RPC: `2332`
- Palladium P2P: `2333`
- ElectrumX TCP: `50001`

---

## Troubleshooting

### Container Won't Start

**Check logs:**
```bash
docker compose logs <service-name>
```

**Common issues:**
- Missing or incorrect RPC credentials
- Port already in use
- Insufficient disk space
- Wrong architecture binaries

### ElectrumX Can't Connect to Node

**Verify:**
1. Node is running: `docker compose ps`
2. RPC works: `docker exec palladium-node palladium-cli -rpcuser=USER -rpcpassword=PASS getblockchaininfo`
3. Credentials match in `palladium.conf`

### Slow Blockchain Sync

**Tips:**
- Copy existing blockchain (Step 4)
- Check internet speed
- Verify addnodes in config
- Be patient (initial sync takes hours/days)

### Port Already in Use

```bash
# Check what's using port
sudo lsof -i :50001

# Kill process or change port in docker-compose.yml
```

### Dashboard Shows Wrong Data

**Force refresh:**
1. Clear browser cache (Ctrl+Shift+R)
2. Check dashboard logs: `docker compose logs dashboard`
3. Restart dashboard: `docker compose restart dashboard`

### Binary Architecture Error

```bash
# Check your system
uname -m
# x86_64 = Intel/AMD 64-bit
# aarch64 = ARM 64-bit

# Check binary
file daemon/palladiumd
# Should match system architecture

# Fix: download correct binaries and rebuild
docker compose build --no-cache
```

---

## Security Recommendations

### Production Deployment

1. **Strong Credentials:**
   - Use long, random passwords for RPC
   - Don't use default credentials

2. **Firewall Configuration:**
   ```bash
   # Allow only required ports
   sudo ufw allow 2333/tcp    # P2P
   sudo ufw allow 50001/tcp   # ElectrumX TCP
   sudo ufw allow 50002/tcp   # ElectrumX SSL
   # Don't expose 8080 publicly without authentication
   sudo ufw enable
   ```

3. **SSL Certificates:**
   - Self-signed certificates are auto-generated on first startup in `./certs/`
   - The certificate includes localhost and the auto-detected public IP in its SAN
   - To use your own certificates (e.g. Let's Encrypt), place `server.crt` and `server.key` in `./certs/` before starting

4. **Dashboard Access:**
   - LAN clients (RFC1918 private IPs) can access without authentication
   - External clients (public IPs) require HTTP Basic Auth automatically
   - Configure credentials in `.env` (copy from `.env.example`):
     ```bash
     DASHBOARD_AUTH_USERNAME=admin
     DASHBOARD_AUTH_PASSWORD=a-strong-random-password
     ```
   - Consider using a VPN instead of exposing port 8080 publicly

5. **Regular Updates:**
   ```bash
   # Update Palladium binaries
   # Update Docker images
   docker compose pull
   docker compose up -d
   ```

6. **Monitoring:**
   - Set up log monitoring
   - Monitor disk space
   - Watch for unusual activity in dashboard

## Performance Tuning

### System Resources

**Minimum:**
- 2 CPU cores
- 4GB RAM
- 50GB storage

**Recommended:**
- 4+ CPU cores
- 8GB+ RAM
- 100GB+ SSD storage

### Docker Resource Limits

Edit `docker-compose.yml` to add limits:

```yaml
services:
  palladiumd:
    deploy:
      resources:
        limits:
          cpus: '2'
          memory: 2G
```

### ElectrumX Performance

Increase concurrent indexing (in `docker-compose.yml`):

```yaml
environment:
  INITIAL_CONCURRENT: "4"  # Default: 2
```

---

## Notes

* **Data Persistence:** All data stored in `./.palladium/`, `./electrumx-data/`, and `./certs/`
