According to Wu Blockchain, the veteran PoW public chain Ravencoin has disclosed that a critical consensus vulnerability in its network has been exploited, causing some nodes to accept invalid blocks. The first known abnormal block appeared at height 4,487,776. Currently, 2Miners and RavenMiner, which control the majority of the hashrate, are mining a new chain from this height to exclude the abnormal branch. If this becomes the main chain, the network could undergo a deep reorganization of approximately three days. Ravencoin recommends that exchanges temporarily halt RVN deposits and withdrawals and treat transactions after block 4,487,775 as being at risk of rollback. https://(wublock123.com)/news/ravencoin-pow-chain-consensus-vulnerability-network-three-day-reorg-66283
