Privacy blockchain Zano activated its sixth hard fork, HF6, on Aug. 31 at block height 3,833,000, with the upgrade now live on mainnet. The release marks the largest upgrade in the network’s seven-year history. HF6 adds Gateway Addresses, a feature designed to give centralized exchanges, decentralized exchanges and cross-chain bridges a directly traceable single balance with instant synchronization, while keeping existing addresses and their privacy model intact. Following the upgrade, native ZANO can now move in a non-custodial way to Ethereum, Solana and TON. Zano said assets are public on those external networks and regain privacy protection once bridged back to Zano. The upgrade also tightens consensus validation rules and strengthens wallet encryption, mining pool fault tolerance, payment IDs, anti-DoS limits, SOCKS5 proxy support and RPC interfaces. According to Bitcoin.com News, HF6 is also a prerequisite for the Zano Execution Layer, an EVM-compatible chain under development that does not yet have a fixed launch date. Zano’s next-generation consensus protocol, Zenith, is listed on its 2027 roadmap.

Privacy-focused blockchain Zano has activated its sixth hard fork, HF6, at block height 3,833,000, with the upgrade now live on mainnet. The network described it as the largest upgrade in its seven-year history. HF6 introduces Gateway Addresses, a feature designed for centralized exchanges, DEXs and cross-chain bridges that offers a directly traceable single balance and instant synchronization while keeping existing addresses and their privacy model unchanged. The upgrade also allows native ZANO to move in a non-custodial manner to Ethereum, Solana and TON. Once on those external networks, the asset is public; when bridged back to Zano, its privacy protections return. Beyond cross-chain changes, HF6 tightens consensus validation rules and strengthens wallet encryption, mining pool fault tolerance, payment IDs, anti-DoS limits, SOCKS5 proxy support and RPC interfaces. HF6 is also described as a prerequisite for the Zano Execution Layer, an EVM-compatible chain still under development with no fixed launch date. Zano’s next-generation consensus protocol, Zenith, has been placed on the project’s 2027 roadmap.
