The Zano network was attacked due to a gateway address vulnerability, forcing it to restart the blockchain.
According to The Block (@TheBlockCo), the Zano network was recently subjected to a Gateway Address vulnerability attack, resulting in the unauthorized minting of ZANO and fUSD that have since entered the market. To contain the losses, the team has urgently restarted the blockchain. The team is currently actively negotiating with affected projects and relevant counterparties regarding compensation for losses, and will publish a formal compensation and claims process in the near future.
