Zano rolls blockchain back to pre-Hard Fork 6 height after Gateway Address exploit
The Zano network restarted its chain at the block height just before Hard Fork 6, undoing about a month of history after an exploit tied to Gateway Addresses.
Zano has restarted its blockchain from the block height immediately preceding Hard Fork 6, rolling the network back roughly a month after an exploit involving Gateway Addresses. Gateway Addresses were the feature introduced by that upgrade, meaning the rollback removes them from the active chain.
- The chain was restarted at the height immediately before Hard Fork 6
- Hard Fork 6 introduced Gateway Addresses, the feature connected to the exploit
- The rollback discards about a month of blocks and transactions
Why the rollback matters
A rollback of this depth means blocks and transactions produced after the chosen height are no longer part of the canonical chain. The restart point was set at the block just before the upgrade that added Gateway Addresses, effectively reverting the network to its pre-fork state.
Deep reorganisations are uncommon because they require broad coordination among node operators and raise questions about activity confirmed after the rollback point. Zano has not, in the material available, detailed how affected users will be handled or when Gateway Addresses might return in a revised form.
