Privacy blockchain project Zano said it has rolled back its chain to block height 3,833,000, which is before its sixth hard fork, and removed roughly one month of on-chain transaction history to address an inflation bug tied to Gateway Addresses. The flaw allowed unauthorized minting of both ZANO, the network’s native token, and the dollar-pegged stablecoin fUSD. Zano said its core consensus protocol, wallet spend keys, and ordinary transaction privacy were not affected, though nodes, miners, stakers, and service providers need to adopt the update. Freedom Dollar said several million dollars in assets held by the project had been exchanged for counterfeit fUSD, and that the project will absorb the related losses. It also asked fUSD holders to pause economic activity involving the token until the repaired Zano chain is confirmed stable. The report was cited by Bitcoin.com News.
