Ravencoin Consensus Vulnerability Exploit (August 2026)
Last changed 2026-10-17 · Community evidence — A moderator accepted a piece of community-submitted evidence: Decrypt confirms the first invalid Ravencoin block at height 4,487,776 on Aug 7, 2026, Upbit and Bitvavo freezing RVN, a 20.4% price drop, and mining pools 2Miners/RavenMiner (majority hash rate) excluding the exploited chain — matching the note.

anchored·3kwvgj…HK3vSummary
On August 7, 2026, an attacker exploited a critical consensus vulnerability in the Ravencoin (RVN) network by manipulating the nHeight field in KAWPOW block headers to bypass proof-of-work verification. Invalid blocks were accepted by vulnerable nodes beginning at block height 4,487,776, prompting exchanges Upbit, Bitget, and Bitvavo to suspend RVN deposits and withdrawals and causing RVN to fall approximately 19% to around $0.00288. An emergency patch (v4.6.1.1-hf1) was released on August 10, 2026 by mining pool 2Miners rather than Ravencoin's core development team, marking at least the third significant consensus-level failure in the network's history.

Community submissions
“[Scout] A critical consensus vulnerability was demonstrated and exploited on the Ravencoin network, with the first known invalid block appearing at height 4,487,776 on August 7, 2026. South Korea's Upbit and the Netherlands' Bitvavo froze RVN movement, and RVN fell 20.4% on the day. The fix treats block 4,487,775 as the last valid block; mining pools 2Miners and RavenMiner, which control a majority of network hash rate, are mining a chain that excludes the exploited branch.”
