Zerocoin is a project focused on addressing the lack of privacy in Bitcoin transactions. It proposes an extension to the Bitcoin protocol, named 'Zerocoin', to allow users to mix their coins, ensuring privacy. The project has evolved into the Zerocash protocol, aiming to develop a full-fledged digital currency, Zcash, that enables direct private payments with hidden values. Unlike traditional Bitcoin transactions, Zerocoin and Zerocash transactions are designed to be untraceable, offering users strong mathematical guarantees of privacy.
