Best Practices

Security Best Practices

# 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

# 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

# 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

# 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"
