# Pezkuwi Beta Testnet - Validator Package v2.0.0 # Pezkuwi Validator Setup - Multi-Network Deployment v3.0.0
Simplified validator setup package for Pezkuwi blockchain beta testnet with 8 validators running on a single machine. Complete validator setup package for Pezkuwi blockchain with support for multiple networks and distributed deployment across separate machines.
## Overview
This repository provides an automated setup system for deploying Pezkuwi blockchain validators across distributed infrastructure. Designed for multi-network deployment (beta testnet, staging, mainnet) with each validator running on its own dedicated machine.
## Architecture
**Distributed Deployment Model:**
- Each validator runs on a separate physical/virtual machine
- Each validator builds its own SDK and frontend locally
- Validators connect sequentially: V2→V1, V3→V2, V4→V3, etc.
- Bootnode information shared manually between operators
- No shared resources between validators
**Network Support:**
- **Beta Testnet**: 8 validators (fully configured with keys)
- **Staging**: 20 validators (validator1 ready, others to be added)
- **Mainnet**: 100 validators (validator1 ready, others to be added)

## Quick Start
### For Validator Operators
You will receive a single command via WhatsApp that looks like this:
```bash
# Example: Setting up validator 8 on beta testnet
git clone https://github.com/pezkuwichain/pezkuwi-validator-v1.0.0.git
cd pezkuwi-validator-v1.0.0
sudo ./setup.sh beta_testnet 8
```
That's it! The script will:
1. ✅ Check and install all missing dependencies
2. ✅ Clone and build Pezkuwi SDK (~15-30 minutes)
3. ✅ Clone and build DKSweb frontend
4. ✅ Prompt for bootnode information (if validator > 1)
5. ✅ Configure validator-specific settings
6. ✅ Create systemd service
7. ✅ Setup Nginx for frontend
8. ✅ Provide clear next-step instructions
### Setup Script Usage
```bash
sudo ./setup.sh <network> <validator_number>
```
**Parameters:**
- `<network>`: Network to deploy on
- `beta_testnet` - Beta testnet (8 validators)
- `staging` - Staging network (20 validators)
- `mainnet` - Production network (100 validators)
- `<validator_number>`: Your validator number (1-8 for beta, 1-20 for staging, 1-100 for mainnet)
**Examples:**
```bash
# Beta testnet validator 1 (bootnode)
sudo ./setup.sh beta_testnet 1
# Beta testnet validator 8
sudo ./setup.sh beta_testnet 8
# Staging network validator 5
sudo ./setup.sh staging 5
# Mainnet validator 42
sudo ./setup.sh mainnet 42
``` ```

### 1. Initial Setup **Pattern:** Each subsequent validator increments all ports by 1.
Run the main setup script with a validator number (1-8): ## Validator Management
### Systemd Service Commands
The setup script creates a systemd service for each validator:
```bash ```bash
cd /home/mamostehp/pezkuwi-validator-v2.0.0/beta_testnet # Start your validator
sudo ./setup.sh 1 sudo systemctl start pezkuwi-validator-beta_testnet-8
```
This will: # Stop your validator
- Check all dependencies sudo systemctl stop pezkuwi-validator-beta_testnet-8
- Clone/update Pezkuwi-SDK (if needed)
- Build SDK in release mode (shared build)
- Clone/update DKSweb frontend (if needed)
- Build and deploy frontend with Nginx
- Insert validator keys
- Create systemd service
- Start the validator
### 2. Setup Additional Validators # Restart your validator
sudo systemctl restart pezkuwi-validator-beta_testnet-8
```bash # Check validator status
sudo ./setup.sh 2 sudo systemctl status pezkuwi-validator-beta_testnet-8
sudo ./setup.sh 3
# ... up to 8
```
### 3. Verify All Validators Are Running # View live logs
sudo journalctl -u pezkuwi-validator-beta_testnet-8 -f
```bash
./scripts/status.sh
```
## Helper Scripts Usage
### Start Validator
Start a single validator:
```bash
./scripts/start.sh 1
```
Start all validators:
```bash
for i in {1..8}; do ./scripts/start.sh $i; done
```
### Stop Validator
Stop a single validator:
```bash
./scripts/stop.sh 1
```
Stop all validators:
```bash
for i in {1..8}; do ./scripts/stop.sh $i; done
```
### Check Status
Check single validator:
```bash
./scripts/status.sh 1
```
Check all validators:
```bash
./scripts/status.sh
```
### View Logs
View logs for a validator:
```bash
./scripts/logs.sh 1
```
Follow logs in real-time:
```bash
./scripts/logs.sh 1 follow
```
## Systemd Service Management
Validators are managed as systemd services:
```bash
# Start validator
sudo systemctl start pezkuwi-validator-1
# Stop validator
sudo systemctl stop pezkuwi-validator-1
# Restart validator
sudo systemctl restart pezkuwi-validator-1
# Check status
sudo systemctl status pezkuwi-validator-1
# View logs
sudo journalctl -u pezkuwi-validator-1 -f
# Enable auto-start on boot # Enable auto-start on boot
sudo systemctl enable pezkuwi-validator-1 sudo systemctl enable pezkuwi-validator-beta_testnet-8
# Disable auto-start # Disable auto-start
sudo systemctl disable pezkuwi-validator-1 sudo systemctl disable pezkuwi-validator-beta_testnet-8
```
**Service Name Pattern:**
`pezkuwi-validator-<network>-<validator_number>`
Examples:
- `pezkuwi-validator-beta_testnet-1`
- `pezkuwi-validator-staging-5`
- `pezkuwi-validator-mainnet-42`
### Log Files
Logs are stored in your validator directory:
```bash
# After setup completes, logs are at:
# /home/mamostehp/pezkuwi-validator/beta_testnet/validators/validator8/logs/
# View validator log
tail -f ~/pezkuwi-validator/beta_testnet/validators/validator8/logs/validator.log
# View error log
tail -f ~/pezkuwi-validator/beta_testnet/validators/validator8/logs/validator-error.log
``` ```
## Validator Keys ## Validator Keys
Each validator has 6 types of keys pre-configured in `validators/validatorN/config/keys.sh`: Each beta testnet validator has 6 types of pre-configured keys:
- **BABE** - Block authorship (sr25519) - **BABE** - Block authorship (sr25519)
- **GRANDPA** - Finality (ed25519) - **GRANDPA** - Finality (ed25519)
@@ -199,117 +217,218 @@ Each validator has 6 types of keys pre-configured in `validators/validatorN/conf
- **AUDI** - Authority discovery (sr25519) - **AUDI** - Authority discovery (sr25519)
- **BEEF** - BEEFY consensus (ecdsa) - **BEEF** - BEEFY consensus (ecdsa)
**SECURITY WARNING**: These keys are for beta testnet only. Never use testnet keys in production! Keys are stored in:
```
beta_testnet/validators/validator<N>/config/keys.sh
```
**⚠️ SECURITY WARNING**:
- Beta testnet keys are for testing only
- Never use testnet keys in staging or production
- Keep production keys secure and backed up offline
- Never commit private keys to version control
## Bootnode Connection
### For Validator 1 (Bootnode)
After starting your validator, you'll need to share your bootnode information:
1. Start your validator:
```bash
sudo systemctl start pezkuwi-validator-beta_testnet-1
```
2. Check logs for your peer ID:
```bash
tail -f ~/pezkuwi-validator/beta_testnet/validators/validator1/logs/validator.log | grep "Local node identity"
```
3. You'll see something like:
```
Local node identity is: 12D3KooWAbCdEf...
```
4. Share your bootnode multiaddr with validator 2:
```
/ip4/YOUR_PUBLIC_IP/tcp/30333/p2p/12D3KooWAbCdEf...
```
### For Validators 2-8
During setup, you'll be prompted:
```
Please obtain the bootnode multiaddr from validator N-1
Enter bootnode multiaddr (or press Enter to skip):
```
Paste the multiaddr you received from the previous validator.
## Frontend Access ## Frontend Access
After setup, DKSweb frontend is available at: After setup, the DKSweb frontend is available at:
- **Local**: http://localhost (via Nginx)
- **Local**: http://localhost
- **Network**: http://YOUR_SERVER_IP - **Network**: http://YOUR_SERVER_IP
The frontend connects to validator 1 (bootnode) by default at `ws://127.0.0.1:9944`. The frontend connects to your local validator node and provides:
- Wallet management
- Token transfers
- Staking operations
- Network statistics

## Security Best Practices ## Security Best Practices
1. **Never expose RPC ports to public internet** - Use firewall rules 1. **🔒 Firewall Configuration**
2. **Backup validator keys securely** - Store encrypted backups offline - Only expose P2P port (30333+) to internet
3. **Use different keys for production** - Never reuse testnet keys - Block RPC/WebSocket ports from external access
4. **Keep system updated** - Regular security updates - Use SSH key-based authentication only
5. **Monitor validator logs** - Watch for suspicious activity
6. **Restrict SSH access** - Use key-based authentication only 2. **🔑 Key Management**
7. **Run validators as non-root** - Use dedicated user accounts - Backup keys to offline storage
- Never share private keys or seeds
- Use different keys for each network
- Rotate keys periodically
3. **🛡️ System Security**
- Keep system updated: `sudo apt update && sudo apt upgrade`
- Run validator as non-root user
- Enable automatic security updates
- Monitor logs for suspicious activity
4. **📊 Monitoring**
- Set up monitoring alerts
- Check validator uptime regularly
- Monitor disk space usage
- Watch for sync issues
5. **💾 Backups**
- Backup validator keys regularly
- Document your validator setup
- Keep recovery procedures updated

### Common Questions
**Q: How long does initial sync take?**
A: Initial blockchain sync can take several hours depending on network size and your connection speed.
**Q: Can I run multiple validators on one machine?**
A: Not recommended for this deployment model. Each validator should have dedicated hardware.
**Q: What if I lose my keys?**
A: Always backup keys securely. Lost keys mean lost validator access.
**Q: Can I change my validator number?**
A: No, validator numbers are assigned and fixed per network.
