As the campaign owner, you can set some restrictions on your campaign, and it will go public once it is confirmed, giving extra confidence for your campaign. Ending requirements include minimum block height, minimum timestamp, and minimum offering token sold. A campaign cannot be concluded without all the ending requirements met. You can always change these settings until it is confirmed. Once it is confirmed, the requirements will be set in stone and go public, please review carefully before confirming (by hitting the "Confirm Requirements" button).
