Project Overview
Zano, a privacy-centric blockchain ecosystem that was launched in 2019. Zano transactions are untraceable, leveraging ring signatures and stealth addresses. Furthermore, the Zarcanum hardfork will incorporate Confidential Assets, privacy tokens that operate on the Zano blockchain. These assets share the same privacy features as native Zano coins, allowing other developers to run their privacy-oriented projects without the overhead of maintaining their own blockchains, dealing with consensus issues, or other complexities of network operation. Zano's security is fortified by a unique hybrid PoW-PoS consensus algorithm, which is also applicable to assets. In addition to these features, Zano supports on-chain aliases, escrow contracts, and has a built-in staking system with no minimum requirements or time locks. It offers numerous features for both users and developers.
Zano Blockchain Rolled Back 30 Days Due to Over $200 Million in Illicit Tokens
Zano disclosed a validation flaw in the Gateway Addresses introduced by Hard Fork 6. An attacker minted approximately 18.4 million ZANO in a single transaction on August 29, then minted an equal amount again on September 25, and minted fUSD in the same manner.The project team stated that the value of the illicit tokens involved exceeds $200 million, with potentially affected activity involving 117,941 outputs and 65,301 transactions. Zano has restored the chain state from block 3,833,000 and disabled Gateway Addresses. All affected balances will be fully restored, and the ZANO supply and issuance schedule will remain unchanged.

Zano Completes 30-Day Blockchain History Rollback and Releases Hotfix, Network Now Running Stably on Updated Chain
Odaily reports: The privacy-focused public chain Zano team has stated that in response to the inflation vulnerability discovered last Friday, a hotfix has been deployed, and the network is now running stably on the updated chain. The chain previously rolled back the block height to 3,833,000, erasing 30 days of previously confirmed transaction records.The Zano team stated that third-party wallets, exchanges, and payment service providers must first update their own nodes to the updated chain before they can safely resume transfers of ZANO and Zano-issued assets. Service providers will announce recovery progress through official channels, and recovery procedures for affected users are being prepared.The native asset ZANO has dropped 32% in price this week and 40.6% since the start of 2026. Zano's official X account stated that users can update their iOS, Android, and desktop wallets, and the team will soon release more details on the recovery process. (Bitcoin.com News)
The Zano network was attacked due to a gateway address vulnerability, forcing it to restart the blockchain.
According to The Block (@TheBlockCo), the Zano network was recently subjected to a Gateway Address vulnerability attack, resulting in the unauthorized minting of ZANO and fUSD that have since entered the market. To contain the losses, the team has urgently restarted the blockchain. The team is currently actively negotiating with affected projects and relevant counterparties regarding compensation for losses, and will publish a formal compensation and claims process in the near future.
Zano rolls back to before the 6th hard fork, deleting about a month of on-chain transaction records
privacy blockchain project Zano has rolled back its blockchain to block height 3,833,000, before the 6th hard fork, deleting approximately one month of on-chain transaction records in order to address an inflation vulnerability involving Gateway Addresses.The vulnerability allowed unauthorized minting of the native token ZANO and the USD-pegged stablecoin fUSD. Zano stated that the core consensus protocol, wallet spending keys, and ordinary transaction privacy were not affected, and that nodes, miners, stakers, and service providers need to adopt the update.Freedom Dollar stated that millions of dollars in assets held by the project had been swapped into counterfeit fUSD, and that the related losses will be borne by the project. Freedom Dollar has asked fUSD holders to suspend economic activity involving the token until the stabilized Zano chain is confirmed after repairs. (Bitcoin.com News)
Zano to Roll Back ~24 Hours of On-Chain History Due to Inflation Bug
Odaily reports: Privacy blockchain network Zano has disclosed that an inflation vulnerability involving Gateway Addresses has forced it to plan a rollback of approximately 24 hours of blockchain history, and has urged users to immediately cease all economic activity related to ZANO and Confidential Assets.Zano has promised to compensate for losses caused by the rollback, but has not yet announced the target block height for the rollback, the patched version, the compensation process, the mechanics of the vulnerability, or the amount of unauthorized assets created. Gateway Addresses went live on August 26 with Hard Fork 6. (Bitcoin.com News)

Zano's sixth hard fork goes live, native ZANO enables non-custodial cross-chain transfers to Ethereum, Solana, and TON
Privacy-focused public chain Zano activated its sixth hard fork (HF6) at block height 3,833,000 on August 31. The upgrade is now live on the mainnet, marking the largest upgrade in the network's seven-year history.HF6 introduces Gateway Addresses, providing centralized exchanges, DEXs, and cross-chain bridges with directly trackable single balances and instant synchronization, while preserving existing addresses and their privacy model. Native ZANO can now be transferred non-custodially across chains to Ethereum, Solana, and TON, where it becomes public on external networks, and privacy protection is restored upon transferring back to Zano.The upgrade also tightens consensus validation rules and enhances wallet encryption, mining pool fault tolerance, payment IDs, anti-DoS restrictions, SOCKS5 proxy, and RPC interfaces.HF6 is a prerequisite for the EVM-compatible chain Zano Execution Layer, which is currently in development and has no fixed launch date yet; the next-generation consensus protocol Zenith has been included in the 2027 roadmap.

Zano plans to transition to pure PoS through Zenith in 2027, reducing block time to 15 seconds
: Privacy blockchain Zano has announced that Zenith has entered the implementation phase, with a network transition planned for 2027, subject to testing, analysis, and review results. Zano has not yet announced an activation date, and the proposed operational parameters still require verification at the network level. Zenith will transition Zano from a hybrid PoW and PoS mechanism to a privacy-preserving pure PoS protocol. The proposed block time will be reduced from approximately 1 minute to about 15 seconds, the recommended number of confirmations will be lowered from 10 blocks to 4 to 6 blocks, and the typical confirmation time will be around 60 to 90 seconds. Andrey Sabelnikov, co-founder and core developer of Zano, stated that Zenith is based on over 12 years of privacy research, aiming to provide the network with the advantages of modern PoS while retaining the privacy protections that Zano users expect. PoW miners currently receive approximately 720 newly issued ZANO per day, equivalent to around 21,600 per month and 262,800 per year. After Zenith is activated and PoW mining ends, this issuance will be discontinued. Zano has also launched the official Zano Forum for technical discussions and community support.
