According to CoinMeta, Zano indicates that the blockchain has been rolled back to block height 3,833,000, which is before the 6th hard fork, in order to delete approximately one month's worth of transaction records on the chain in order to address an inflation vulnerability involving gateway and addresses. This vulnerability allowed for the unauthorized issuance of the native token Zano and the dollar-pegged stablecoin FUSD. Zano states that the core consensus protocol, wallet spending keys, and the privacy of regular transactions were not affected; however, nodes, miners, stakers, and service providers need to adopt the updates. Freedom Dollar mentions that millions of dollars in assets held by the project were exchanged for counterfeit FUSD, and the related losses will be borne by the project. Freedom Dollar has requested that holders of FUSD suspend any economic activities involving this token until the repaired Zano chain is confirmed to be stable.
