Zano Rolls Back 30 Days of Chain History to Neutralize Major Inflation Glitch
Privacy network Zano executed a month-long blockchain rollback to block height 3,833,000 to eliminate an inflation exploit.

Privacy-focused cryptocurrency network Zano has executed an unprecedented Zano blockchain rollback, wiping approximately one full month of ledger activity to rectify a severe inflation vulnerability. Developers initiated the deep chain reorganization back to block height 3,833,000 after determining that newly minted unauthorized tokens posed an existential threat to the economic integrity of the ecosystem.
While initial communications suggested the chain might only need a minor 24-hour reversion, technical reviews revealed that the underlying vulnerability required a far more aggressive remedy. According to Bitcoin.com News, the development team confirmed that 30 days of transactional history were permanently erased to completely neutralize the supply anomaly and restore original protocol balances.
Chain rollbacks of this magnitude are extremely rare in decentralized systems, as wiping weeks of confirmed transactions creates complex friction for node operators, miners, and external service providers. However, preserving the fixed tokenomics and preventing unbacked coin proliferation took priority over maintaining recent ledger continuity.
The broader crypto community reacted with surprise at the operational scope of the fix, debating the centralization trade-offs required to execute deep state overwrites. Despite the controversy, core contributors emphasized that leaving the inflated supply intact would have permanently broken user trust and undermined the network's foundational cryptographic model.
Moving forward, ecosystem participants will monitor node synchronization progress, exchange integration reconnects, and the release of permanent protocol patches. The Zano team is expected to publish an exhaustive post-incident audit to detail how the bug originated and outline preventive automated tests for future releases.
Key takeaways
- Zano rolled back its ledger to block 3,833,000, erasing one month of transaction history.
- The drastic state reorganization was necessary to eliminate a major supply inflation vulnerability.
- Core developers prioritized economic integrity over recent ledger continuity to preserve tokenomics.
