Privacy public chain Zano restarted the blockchain from block 3833000, rolling back about a month of on chain history to clear unauthorized circulation of ZANO and Freedom Dollars (fUSD) during the vulnerability period. The project party claims that the expenditure key and transaction privacy have not been compromised, and nodes, miners, mining pools, and transactions need to be upgraded to version 2.2.3.600 to follow the recovery chain. MEXC has suspended the deposit and withdrawal of ZANO and fUSD. Compensation will be paid using development funds, team holdings, and large funds, and no additional ZANO will be issued.
