There are two ledgers, one is public , the other one is pvt. you can use them as you wish. if you google you can find info yourself.

What is Wraith Protocol?
Wraith Protocol is a technology that allows the user to seamlessly switch between public and private ledgers on the Verge Blockchain. For the first time, users are now free to choose which ledger they want to utilize.

To break it down, when Wraith Protocol is turned ON — the transaction data is hidden and not visible via the blockchain explorer.

In a circumstance where transparency is required, Wraith Protocol would be turned OFF, allowing the transaction data to be viewable on the public ledger.

In addition, Verge provides total obfuscation of IP addresses in both cases, thanks to the most advanced version of TOR integrated in the Core Wallet. In combination with Wraith Protocol it makes Verge the only truly untraceable cryptocurrency. ( courtesy - medium.com)
