   Zano rolls blockchain back a month after Gateway Address exploit

   Following a Gateway Address exploit that let unauthorized ZANO and Freedom Dollar enter circulation, Zano restarted its blockchain at block 3,833,000 — just before Hard Fork 6 — rolling back about a month of history and invalidating legitimate transactions from that period.

   Zano rolls back a month of transactions as team plans to use personal funds for recovery

   Zano's team announced it will draw on the developer fund, team members' personal funds, and committed contributors to finance recovery for users affected by the rollback, but eligibility rules, payment amounts, and a timetable are not yet published; it also said the network is stable, ZANO supply and emission remain unchanged, wallet spend keys and ordinary transaction privacy were not compromised, and a full post-mortem is pending.

   State after update: After the Gateway Address exploit allowed unauthorized ZANO and Freedom Dollar into circulation, Zano restarted its chain at block 3,833,000, rolling back about a month of transactions; the team has promised recovery funding through the developer fund, personal funds, and contributors, but the claims process and payment rules are not yet live.

   Zano exploiter created 36.9M unauthorized ZANO before blockchain rollback

   Zano's post-mortem revealed the attacker exploited the Gateway Address vulnerability to mint about 18.4M ZANO on Aug. 29 and another 18.4M on Sept. 25, totaling 36.9M unauthorized ZANO plus fUSD; the attacker paid a 100 ZANO registration fee, tested a fabricated asset first, and the first mint went unnoticed for nearly a month. Recovery will primarily run through exchanges and payment services, with exchanges to replay withdrawals reversed by the rollback and the team crediting affected deposits.

   State after update: Zano has confirmed the Gateway Address exploit minted 36.9M unauthorized ZANO plus fUSD and has rolled back about a month of chain history; recovery is now being carried out primarily through exchanges and payment services, with exchanges to replay withdrawals reversed by the rollback and the team crediting affected deposits.
