The Ravencoin blockchain is grappling with a dual crisis: a critical consensus vulnerability exploit that has split its network and simultaneous delisting warnings from South Korea’s two largest exchanges, Upbit and Bithumb. The combination threatens the token’s market integrity and liquidity.
The security breach came to light when an invalid block appeared at height 4,487,776. Hackers actively exploited a flaw that allowed vulnerable nodes to validate blocks violating consensus rules, creating a divergent chain. Two major mining pools, 2Miners and RavenMiner, which together command more than half of the network’s hash rate, are now mining a new branch starting from that height, excluding the attack’s blocks. If this becomes the main chain, a deep reorganization covering roughly three days of transactions could occur, potentially enabling double-spending and reversing asset transfers. Ravencoin has urged centralized exchanges to suspend RVN deposits and withdrawals until stability returns.
Compounding the turmoil, Upbit and Bithumb placed Ravencoin on their delisting watchlists, a formal step that often precedes removal. While specific reasons were not fully disclosed, the move aligns with heightened scrutiny under South Korea’s Virtual Asset User Protection Act, enacted in 2024. The regulatory pressure forces exchanges to vet tokens for compliance, development activity, and trading volume. A potential delisting would strip RVN of two critical on-ramps, slashing liquidity and amplifying price volatility—a pattern seen with other tokens that were later dropped.
For RVN holders, the immediate priority is to avoid transacting during the network’s unstable phase and to monitor official exchange announcements. The network’s ability to patch the vulnerability and regain miner consensus will be pivotal, while the project team may need to address the exchange concerns head-on. The incident underscores the fragility of smaller proof-of-work chains and the growing power of exchanges in shaping a token’s fate.
