Ravencoin is facing a potential rollback of up to four days of transactions following the exploitation of a critical consensus vulnerability that allowed invalid blocks to be added to its blockchain. The flaw first appeared at block height 4,487,776 on Friday. Two major mining pools, 2Miners and RavenMiner, which together control a majority of the network's hash rate, are building a competing chain that excludes the exploited branch from that block onward. If this miners' chain becomes dominant, the network could undergo a reorganization spanning approximately three days, potentially reversing transactions confirmed after block 4,487,775. Ravencoin advised exchanges to halt deposits and withdrawals until the chain stabilizes. The cryptocurrency's native token, RVN, dropped to a new all-time low of $0.002754 on Wednesday, a decline of about 22% from its 24-hour high, with trading volume surging during the sell-off. Exchanges such as Upbit and Bitget have suspended RVN transfers as a precaution.
