Ravencoin’s official account has just posted on X a warning: a critical consensus vulnerability has appeared on the network and has already been exploited. Vulnerable nodes have accepted invalid blocks, and the first invalid block is at height 4,487,776.
Currently, 2Miners and RavenMiner—together controlling the majority of the hash rate—are jointly mining a new chain that excludes the exploited branch from this height onward. If this new chain becomes the main chain, it could trigger a deep chain reorganization lasting about 3 days.
Key takeaways at a glance:
1. The vulnerability is a defect at the consensus layer, which allowed attackers to produce invalid blocks.
2. 2Miners and RavenMiner have coordinated a hash rate switch; the reorg depth may reach three days.
3. The official recommends that exchanges immediately pause deposits and withdrawals for $RVN .
4. Transactions confirmed after height 4,487,775 are considered at risk.
For ordinary users, there are three main things to focus on: (1) Don’t deposit or withdraw RVN on exchanges until the official issues further notice; (2) Transactions in self-custody wallets after block height 4,487,775 should be treated with caution due to rollback risk; (3) Don’t fall for any phishing links claiming “compensation” or “rollback recovery.”
This incident once again reminds us: for small PoW chains with concentrated hash power, deep reorganization is a double-edged sword— it can be used to remove attacker blocks, but it also significantly increases uncertainty in on-chain history.
