Zano rolls back to before the 6th hard fork, deleting about a month of on-chain transaction records

Odaily reports that 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)
