Zano Network Stabilizes After 30-Day Blockchain Rewind – Bitcoin News

Analysis
Zano's decision to rewind 30 days of chain history to block 3,833,000 marks a far more severe intervention than the one-day rollback initially floated after an inflation bug tied to Gateway Addresses, and it shifts the burden onto exchanges, third-party wallets, and payment processors that must resync nodes before transfers resume. The confirmed hotfix and stable chain reduce immediate consensus risk, but the erased transaction window leaves unresolved questions about how affected users will be compensated and whether balances created during the reverted period are honored. Watch for the promised user recovery plan, confirmation from major exchanges that deposits and withdrawals are re-enabled, and whether the incident prompts changes to Gateway Address design or audit practices. The 32% weekly and 40.6% year-to-date price declines reflect market reaction, though the scale of the rollback relative to past incidents such as Ethereum Classic's 7,000-block reorg is the more durable governance signal.

Key Takeaways The Zano development team deployed a hot fix after rolling back 30 days of blockchain history to block 3,833,000. ZANO’s price has taken a beating, shedding 32% this week and 40.6% since the start of 2026. The official Zano X account said exchanges must update their nodes before resuming transfers, with user recovery plans to be published soon. Zano Team Provides an Update Following Inflation Bug On Friday, Bitcoin.com News reported that the Zano blockchain had an inflation bug tied to Gateway Addresses, and at that time, the development team said that a one-day rollback of the blockchain was necessary. By the following day, however, those plans had taken a considerably more drastic turn, with Zano confirming that its ledger had been rolled back to block height 3,833,000, effectively erasing 30 days of previously confirmed transactions. On Tuesday, Zano’s official X account provided additional details surrounding the incident. “The hotfix has been pushed and the network is stable on the updated chain,” the X post stated. It further explained how users can update their iOS, Android, and desktop wallets as well. “Third-party wallets, exchanges and payment services all need to update their own nodes to the updated chain before they can safely process transactions again,” the team insisted. Zano is not the first chain to roll back transactions as several blockchains have done so in the past, including Bitcoin. However, several of these blockchain rollbacks were certainly not as large. For instance, during the 2010 inflation bug (known as the Value Overflow Incident), 53 Bitcoin network blocks were rolled back. Other chains, such as Bitcoin Gold, Bitcoin SV, Verge, Monero, and Horizen, have logged rollbacks. Ethereum Classic suffered a rollback of over 7,000 blocks back in 2020.
