Zano Erases a Month of History
Zano executed a blockchain rollback to block 3,833,000 — immediately before August 26's Hard Fork 6, which introduced the vulnerable Gateway Address feature — erasing roughly one month of history, per the project's recovery notice and its public explorer. The rollback removes unauthorised ZANO and fUSD but also invalidates a month of legitimate transactions; cross-chain settlements cannot be reversed. A reimbursement process funded by the development fund, team assets and major holders is promised. ZANO traded near $6.32, down ~13% over 24 hours.
Zano: a month erased, because nobody can prove a day would do
Zano didn't roll back a day. It rolled back a month.
The chain restarted at the block immediately before August's Hard Fork 6 — the upgrade that introduced the buggy feature. Everything since, erased. The fake coins, and a month of everyone's real transactions with them.
Why so far? Because on a fully private chain, the team cannot tell when the silent minting started. Every transaction is hidden — including the attacker's.
So they erased the feature's entire lifetime. Not because the damage needed a month. Because nobody can prove it didn't.
The recovery notice lists its company: Bitcoin's 2010 supply bug, Zcash's counterfeiting patch, Ethereum's DAO rewrite. Read that list carefully — they didn't all do the same thing. Bitcoin bent its ledger for hours. Ethereum forked one theft. Zcash never touched its record at all — it bent transparency instead, staying silent for eleven months.
Zano is bending the ledger for a month, and the transparency indefinitely: it still hasn't said whether anyone used the bug, or how much was minted. On this design, it may never be able to.
A reimbursement process is promised — paid from the team's own funds, not new coins. That's the honest way to do it. But note who's being reimbursed: everyone who transacted in September, on a chain that worked.
The promise that no small team can rewrite the record isn't a rule. It's a habit that holds until breaking it is cheaper than not.
Zano just showed you the price: one month of history. The bill — who minted what — remains unshown, and may be unshowable.
