The aims for anonymity and untraceability are the mutual goals of all privacy coins that can most clearly be discovered. Anonymity is one of the core principles behind a privacy coin because it obscures the identity of a person behind a transaction, while untraceability does not allow for third parties to track the trail of transactions on the blockchain. Different techniques were used by each coin to achieve these core values.
