Monero gives its users privacy during transaction. It uses CryptoNote technology that employs ring signatures to hide transaction data. In addition, it also employs viewkey, which is an opaque blockchain structure that requires the use of a private view key in order to view any transactions. In this way, the users’ transaction data is not visible to the public.
In addition to its privacy, the transactions made by XMR users are also untraceable. It is practically impossible to link any transaction to a specific user.
The most unique thing with Monero is it fungibility. This means units of Monero can be substituted for each other while retaining the same value. This ensures that no Monero unit can be blacklisted due to being involved in a certain previous transaction.
