Zano Privacy Blockchain and Wallet Features Explained

Zano is a privacy-centric blockchain ecosystem that transitioned from the Boolberry project in 2019 to provide untraceable transactions and decentralized applications [2]. The platform utilizes a hybrid consensus model that combines Proof-of-Work (PoW) and Proof-of-Stake (PoS) to secure the network while reducing energy consumption [1].

In March 2024, the project implemented the Zarcanum hard fork at block height 2,555,000, which fundamentally changed how the network handles assets [2]. This update introduced Confidential Assets, allowing developers to create privacy-oriented tokens that inherit the same security features as the native ZANO coin [2]. Zarcanum also debuted the first Proof-of-Stake algorithm designed with hidden amounts, ensuring that the specific quantity of coins being staked remains private [2].

The network achieves its privacy goals through several cryptographic techniques. Transactions are obfuscated using d/v-CLSAG Ring Signatures and Stealth Addresses, which prevent the linking of sender and receiver identities [2]. Additionally, the platform employs Bulletproofs+ technology to conceal the specific amount of coins transferred in any given transaction [2]. Because the blockchain does not publicly expose transaction histories or wallet balances, it functions as a tool for private financial interactions [1].

Beyond core privacy features, the Zano ecosystem includes tools for decentralized commerce. Users can create on-chain aliases—simple usernames linked to payment addresses—to simplify the transaction process [2]. The platform also supports customizable escrow contracts, which allow parties to conduct trustless peer-to-peer trades without relying on intermediaries [1]. For users managing their holdings, the Zano wallet offers self-custody, allowing individuals to hold their own keys with biometric and passcode security [1].

The project’s development is led by Andrey Sabelnikov, who previously co-developed the CryptoNote protocol that serves as the foundation for various privacy coins [2]. While the platform is designed for scalability and enterprise-grade privacy, its reliance on a hybrid consensus model is intended to mitigate the "Nothing at Stake" problem, making the network more resilient against potential attacks [2].

As the ecosystem expands, the core question remains whether the platform’s focus on privacy-by-default can maintain its technical performance while attracting broader adoption for its decentralized marketplace and asset-creation tools. Whether these privacy features will satisfy evolving regulatory standards for digital assets remains an open point for the project's long-term trajectory.
