A serious consensus gap in the Ravencoin network was exploited and it was suggested that the exchange suspend its refilling

Wu stated that it had been informed that Ravencoin, an old POW public chain, had indicated that a serious consensus loophole in its network had been used in practice, leading to the acceptance of invalid blocks at some nodes, and that the first known abnormal block appeared at an altitude of 4,487,776. Currently, 2miners and revenminer control most of the calculations and are digging new chains from that height to remove the abnormal branches. If it becomes the main chain, the network may be restructured in depth for about three days. Ravencoin recommended that the exchange suspend RVN recharge and consider the transaction after block 4,487,775 as a rollback risk。
