Zano (ZANO) is a privacy-focused blockchain ecosystem that launched in 2019. It is built on the CryptoNote codebase and prioritizes fast, secure, and private transactions. The network relies on a unique hybrid consensus algorithm combining Proof of Work (PoW) and Proof of Stake (PoS). This approach aims to enhance security and efficiency by leveraging the strengths of both mechanisms, making the network more resistant to various attacks.
Privacy is a core component of Zano’s technology. Transactions are made untraceable using ring signatures and stealth addresses. Ring signatures merge a group of potential signers into a single transaction, obscuring the actual signer. Stealth addresses ensure that a recipient's address is not publicly linked to their transactions, providing an extra layer of privacy.
The planned Zarcanum hardfork intends to introduce several new features. One key addition is the first-ever Proof of Stake algorithm with hidden amounts, which aims to enhance the privacy of staking activities. The hardfork also plans to incorporate Confidential Assets, which are privacy tokens operating on the Zano blockchain. These assets share the same privacy features as native Zano coins, allowing developers to run privacy-oriented projects without the overhead of maintaining separate blockchains.
Zano supports on-chain aliases to improve user-friendliness. Users can create aliases, such as @username, and link them to payment addresses. This feature simplifies transactions and is planned for eventual integration into a dedicated messenger, a user reputation service, and an alias-based authentication system.
Security is further bolstered by multi-signature functionality, which allows multiple users to control a single wallet. This is useful for escrow services or two-factor authentication. Users can also create customizable escrow contracts with required deposits, facilitating trustless agreements between parties.
The built-in staking system has no minimum requirements or time locks, making it accessible to a wide range of users. This system aims to secure the network while allowing users to earn rewards.
As an open-source project, Zano allows for continuous development and improvement. Developers can contribute to the codebase, which the team says fosters transparency and trust within the community.
The network is designed to be scalable, capable of handling a high volume of transactions for both individual users and enterprise applications. This scalability is considered crucial for long-term adoption.
The ecosystem includes tools for both users and developers, such as escrow contracts for secure transactions between untrusted parties. These contracts can be customized with required deposits to ensure obligations are met.
Through the Zarcanum hardfork, the introduction of Confidential Assets will allow developers to build privacy-focused projects on Zano. These assets will benefit from the same privacy features as native coins, eliminating the need for developers to manage their own blockchains or deal with consensus issues. The hybrid PoW-PoS consensus algorithm also applies to these assets, aiming to ensure their security and integrity.
