              After a transaction is broadcast to the Karbo network, it may be included in a block that is published

              With each subsequent block that is found, the number of confirmations is increased by one. To protect against double spending, a transaction should not be considered as confirmed until a certain number of blocks confirm, or verify that transaction.
              6 is considered very safe number of confirmations, although it takes longer to confirm.

                Cron job will take care of all regular Karbo payment processing tasks, like checking if payments are made and automatically completing the orders.<br />
                <b>Soft Cron</b>: - Wordpress-driven (runs on behalf of a random site visitor).
                <br />
                <b>Hard Cron</b>: - Cron job driven by the website hosting system/server (usually via CPanel). <br />
                When enabling Hard Cron job - make this script to run every 5 minutes at your hosting panel cron job scheduler:<br />
                <?php echo '<tt style="background-color:#FFA;color:#B00;padding:0px 6px;">wget -O /dev/null ' . $g_KRBWC__cron_script_url . '?hardcron=1</tt>'; ?>
                <br /><b style="color:red;">NOTE:</b> Cron jobs <b>might not work</b> if your site is password protected with HTTP Basic auth or other methods. This will result in WooCommerce store not seeing received payments (even though funds will arrive correctly to your Karbo addresses).
                <br /><u>Note:</u> You will need to deactivate/reactivate plugin after changing this setting for it to have effect.<br />
                "Hard" cron jobs may not be properly supported by all hosting plans (many shared hosting plans has restrictions in place).
                <br />For secure, fast hosting service optimized for wordpress and 100% compatibility with WooCommerce and Karbo we recommend <b><a href="http://hostrum.com/" target="_blank">Hostrum Hosting</a></b>.
