  "account": "The Zano blockchain has been restored to the block height immediately preceding Hard Fork 6, which introduced Gateway Addresses, following a vulnerability that allowed unauthorized ZANO and Freedom Dollar tokens to enter circulation, according to the core team. This rollback affects approximately a month's worth of blockchain history, invalidating transactions and the unauthorized tokens created during that period. The affected feature, Gateway Addresses, was designed to simplify integration for bridges, exchanges, and payment services by allowing them to manage funds through a single account-style balance. However, it was the source of this exploit. Zano's head of marketing and growth, Quinten van Welzen, stated that not taking action would have diluted every holder and broken the basic promise of a fixed supply, while also allowing future attackers to keep the value of exploited coins. The recovery process requires participating nodes, miners, stakers, exchanges, and other services to adopt the update. The team is currently working on accounting for any losses and will publish a reimbursement and claims process.",
