## Quick Reference Commands

### Daily Operations

```bash
# Quick health check
./aitbc-cli chain && ./aitbc-cli network

# Service status
systemctl status aitbc-blockchain-node.service aitbc-blockchain-rpc.service

# Cross-node sync check
curl -s http://localhost:8006/rpc/head | jq .height && ssh aitbc1 'curl -s http://localhost:8006/rpc/head | jq .height'

# Wallet balance check
./aitbc-cli balance --name genesis-ops
```

### Troubleshooting

```bash
# Check logs
sudo journalctl -u aitbc-blockchain-node.service -f
sudo journalctl -u aitbc-blockchain-rpc.service -f

# Restart services
sudo systemctl restart aitbc-blockchain-node.service aitbc-blockchain-rpc.service

# Check database integrity
sqlite3 /var/lib/aitbc/data/ait-mainnet/chain.db "PRAGMA integrity_check;"

# Verify network connectivity
ping -c 3 aitbc1 && ssh aitbc1 'ping -c 3 localhost'
```

### Performance Monitoring

```bash
# System resources
top -p $(pgrep aitbc-blockchain)
free -h
df -h /var/lib/aitbc

# Blockchain performance
./aitbc-cli analytics --period "1h"

# Network performance
iftop -i eth0
```

## Best Practices

### Security Best Practices

```bash
# Regular security updates
sudo apt update && sudo apt upgrade -y

# Monitor access logs
sudo grep "Failed password" /var/log/auth.log | tail -10

# Use strong passwords for wallets
echo "Use passwords with: minimum 12 characters, mixed case, numbers, symbols"

# Regular backups
sudo cp /var/lib/aitbc/data/ait-mainnet/chain.db /var/backups/aitbc/chain-$(date +%Y%m%d).db
```

### Performance Best Practices

```bash
# Regular database maintenance
sqlite3 /var/lib/aitbc/data/ait-mainnet/chain.db "VACUUM; ANALYZE;"

# Monitor resource usage
watch -n 30 'free -h && df -h /var/lib/aitbc'

# Optimize system parameters
echo 'vm.swappiness=10' | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
```

### Operational Best Practices

```bash
# Use session IDs for agent workflows
SESSION_ID="task-$(date +%s)"
openclaw agent --agent main --session-id $SESSION_ID --message "Task description"

# Always verify transactions
./aitbc-cli transactions --name wallet-name --limit 5

# Monitor cross-node synchronization
watch -n 10 'curl -s http://localhost:8006/rpc/head | jq .height && ssh aitbc1 "curl -s http://localhost:8006/rpc/head | jq .height"'
```

### Development Best Practices

```bash
# Test in development environment first
./aitbc-cli send --from test-wallet --to test-wallet --amount 1 --password test

# Use meaningful wallet names
./aitbc-cli create --name "genesis-operations" --password "strong_password"

# Document all configuration changes
git add /etc/aitbc/.env
git commit -m "Update configuration: description of changes"
```

## Troubleshooting Guide

### Common Issues and Solutions

#### Service Issues

**Problem**: Services won't start
```bash
# Check configuration
sudo journalctl -u aitbc-blockchain-node.service -n 50

# Check permissions
ls -la /var/lib/aitbc/
sudo chown -R aitbc:aitbc /var/lib/aitbc

# Check dependencies
systemctl status redis
```

#### Network Issues

**Problem**: Nodes can't communicate
```bash
# Check network connectivity
ping -c 3 aitbc1
ssh aitbc1 'ping -c 3 localhost'

# Check firewall
sudo ufw status
sudo ufw allow 8006/tcp
sudo ufw allow 7070/tcp

# Check port availability
netstat -tlnp | grep -E "(8006|7070)"
```

#### Blockchain Issues

**Problem**: Nodes out of sync
```bash
# Check heights
curl -s http://localhost:8006/rpc/head | jq .height
ssh aitbc1 'curl -s http://localhost:8006/rpc/head | jq .height'

# Check gossip status
redis-cli ping
redis-cli info replication

# Restart services if needed
sudo systemctl restart aitbc-blockchain-node.service
```

#### Wallet Issues

**Problem**: Wallet balance incorrect
```bash
# Check correct node
./aitbc-cli balance --name wallet-name
ssh aitbc1 './aitbc-cli balance --name wallet-name'

# Verify wallet address
./aitbc-cli list | grep "wallet-name"

# Check transaction history
./aitbc-cli transactions --name wallet-name --limit 10
```

#### AI Operations Issues

**Problem**: AI jobs not processing
```bash
# Check AI services
./aitbc-cli marketplace --action list

# Check resource allocation
./aitbc-cli resource status

# Check job status
./aitbc-cli ai-status --job-id "job_id"

# Verify wallet balance
./aitbc-cli balance --name wallet-name
```

### Emergency Procedures
