Ravencoin’s official account issues a warning: a critical consensus vulnerability has appeared on the PoW network and has already been maliciously exploited.
Key points at a glance:
- The first invalid block appeared at block height 4,487,776, and vulnerable nodes accepted an illegal block.
- The two major mining pools, 2Miners and RavenMiner, control most of the hashrate. They have started excluding the attacked branch from block height 4,487,776 and mining a new main chain.
- If the new chain is accepted by the network, it could trigger an on-chain reorganization with a depth of around three days, affecting confirmed transactions and exchange deposits/withdrawals.
- The official advises exchanges to pause
$RVN deposits/withdrawals, and to treat transactions after block height 4,487,775 as risky.
This is not a normal orphaned block. Instead, the consensus layer has been breached, and the attacker used the vulnerability to make nodes accept an invalid block. For PoW chains, the combination of 51% hashrate plus a consensus vulnerability is more dangerous than a pure hashrate attack, because the attacker’s cost is pushed down to extremely low levels.
Focus on three things:
1) Reorg depth. A three-day rollback means exchange recharge confirmation, deposit confirmation, and payment settlement could all be rewritten, and transactions on the old chain may become invalid.
2) Exchange response speed. Several platforms have already paused
$RVN deposits/withdrawals. Until the network stabilizes, avoid large-value transfers as much as possible.
3) Long-term trust cost. On-chain history is being rewritten, and the Ravencoin community’s confidence in the network’s censorship resistance and immutability may be undermined.
In the short term, the main risks are price volatility and rollback concerns. In the long term, the project team needs to explain the vulnerability details, whether there was a fork, and how to prevent it from happening again.
Reminder: This warning represents only Ravencoin’s official action to increase transparency and does not constitute endorsement of any rollback or recovery方案. Please follow the latest official announcements for on-chain funds.
