Zano's network is stabilizing after a blockchain rollback that affected about 30 days of history. While operations appear to be settling, the rollback changed the ledger state, and the status of transactions and asset records from the period has not been fully established.
Rollback affected about 30 days of blockchain history
The incident involved a broad rollback of Zano's blockchain, covering roughly 30 days of on-chain history. A rollback returns the ledger to an earlier state, potentially affecting blocks and transactions recorded during that period. Users relying on the chain for transfers, settlement or balance checks will need to refer to the network's current state to determine whether transactions remain valid.
Available information indicates that the network is stabilizing, but does not explain what caused the rollback, how it was triggered or how it was handled. There are also no detailed figures for affected block heights, transaction counts or the precise time period. Without those details, the impact on individual transactions or different types of assets cannot yet be assessed.
Network stability does not settle transaction questions
A ledger rollback spanning several weeks can leave uncertainty around transaction confirmations and balance reconciliation. Users who made transfers during the affected period may need to check whether those transactions appear in the current on-chain record. Exchanges and other service providers may also need to update their records based on the network state they use.
It has not been specified whether Zano issued user instructions or whether exchanges changed deposit, withdrawal or settlement arrangements. The network's return to stability is a notable development, but it does not by itself confirm the rollback's effects on the ledger. Available details do not establish whether transactions were reversed, whether asset balances diverged or how any discrepancies will be resolved. Users' immediate reference point remains the confirmed current on-chain record, alongside any further disclosure from the project about the cause and scope of the rollback.
Cause and impact remain undisclosed
As of information released on September 29, 2026, Zano had experienced a rollback of about 30 days of blockchain history and its network was stabilizing. The cause, scale of affected transactions and outcome of any remediation have not been clarified. Further technical details, on-chain data and information about transaction handling will be important for assessing the network's reliability and the risks to related services.
