🚨
While the market was calmly digesting the news, a serious disruption occurred on-chain #Ravencoin . The token $RVN immediately dropped by almost 20% after the project team announced a critical consensus vulnerability.
🧠 What happened, and where’s the catch?
Consensus bug: Due to a node error, nodes started accepting invalid blocks. The first "defective" block appeared on August 7 at height 4,487,776.
Pool war and reorganization: The largest pools, 2Miners and RavenMiner, which hold over 85% of the main hashrate, have started mining the clean branch from block 4 487 775. This threatens the network with a deep rollback (reorganization) of nearly three days.
Exchange freeze: Developers urged platforms to suspend RVN deposits and withdrawals. Major exchanges, including Upbit and Bitvavo, have already blocked deposits.
Risk of transaction cancellation: All transfers confirmed after block 4 487 775 are in a higher-risk zone and may simply “disappear” when the chain is finalized.
💡 Key takeaway:
This isn’t the first time in the project’s history—in 2020, a network vulnerability allowed attackers to print 21 million extra coins. For traders and investors, this is a clear lesson: technological risk in low-cap PoW networks isn’t going away. The drop from ATH is already over 99%, and similar technical failures finish off liquidity.
