anchored·2EyEPf…ePuXSummary
In August 2026, Ravencoin's mainnet suffered a critical consensus vulnerability in its KAWPOW proof-of-work algorithm that allowed attackers to produce invalid blocks at a fraction of normal mining cost, beginning at block height 4,487,776 on August 7, 2026. Majority mining pools took unilateral control of the recovery process, issuing a patch without the core development team and threatening a deep three-day blockchain reorganization that would reverse all transactions since block 4,487,775. The incident — the network's third known consensus or supply failure — triggered an approximately 19-20% price crash, exchange-wide suspension of RVN transfers, and raised acute governance concerns about the project's effectively inactive development team.

“[Scout] Decrypt reports the first known invalid Ravencoin block appeared at height 4,487,776 on 2026-08-07; 2Miners and RavenMiner, which control a majority of hash rate, are reportedly building a chain excluding it, which could cause a roughly three-day reorganization, and RVN fell about 20%.”
