Zano rolls blockchain back a month after Gateway Address exploit
The Zano blockchain has been restarted at the block height that came immediately before Hard Fork 6, which introduced Gateway Addresses.
Zano has rolled back approximately a month of blockchain history after a vulnerability involving Gateway Addresses allowed unauthorized ZANO and Freedom Dollar to enter circulation, according to its core team.
The Zano blockchain has been restarted at block 3,833,000, immediately before Hard Fork 6, which introduced the affected feature. The recovery requires participating nodes, miners, stakers, exchanges and other services to adopt the update, the team said Sunday.
The rollback invalidates a month of legitimate transactions along with the unauthorized tokens, meaning transactions made during that period will no longer appear on the recovered chain. It also cannot reverse payments already settled on other blockchains. The team said it is working to account for any losses and will publish a reimbursement and claims process.
