Zano rolls back blockchain by a month after gateway address flaw

Privacy-focused layer-one blockchain Zano rolled back about a month of blockchain history after a vulnerability in its gateway address feature led to the unauthorized circulation of ZANO and Freedom Dollar (fUSD), Cointelegraph reported. Zano’s core team restored the network to block 3,833,000, before the affected feature was introduced. As a result, assets created through the vulnerability and legitimate transactions processed during that period were invalidated, and some transactions may require separate settlement. Payments already completed on other blockchains are not included in the rollback.
