Ravencoin Crashes 20% as Critical Exploit Threatens to Rollback Network

Summary

Ravencoin disclosed a critical consensus bug that let invalid blocks be accepted, and attackers have already exploited it. The flaw could force a deep reorganization of about three days, potentially reversing deposits, withdrawals, and payments made since Aug. 7. The network’s leading mining pools said they are mining an alternate chain starting at block 4,487,776, and exchanges were urged to suspend RVN transfers until the chain stabilizes; Upbit and Bitvavo already did so. The token fell about 20%, erasing recent trading range support and cutting its market value sharply.
