Ravencoin Network Notice
A critical consensus vulnerability has been demonstrated and exploited on the Ravencoin network.
The issue caused invalid blocks to be accepted by vulnerable nodes. The first known invalid block appeared at height 4,487,776 on 2026-08-07 15:44:01 UTC.
After the vulnerability was demonstrated on mainnet, similar invalid blocks appear to have been produced by others as well.
2Miners and RavenMiner currently control a majority of the network hash rate and have announced that they are mining a chain which excludes the exploited branch from height 4,487,776 onward.
If that chain becomes the dominant chain, this may result in a deep chain reorganization of approximately three days.
I asked the pools to consider a more recent recovery point to reduce the impact on users, services and exchanges. That request was declined.
My recommendation to exchanges is clear: temporarily suspend RVN deposits and withdrawals until the network situation is resolved and the chain state is stable.
Transactions confirmed after block 4,487,775 should be treated as at risk. Some affected transactions may return to the mempool and be mined again, but this is not guaranteed.
Exchanges should not assume that reversed deposits or withdrawals will automatically reappear or be confirmed again.
Users should avoid relying on recent confirmations until the network has stabilized.
This notice is shared for transparency and risk awareness. It should not be interpreted as an endorsement of any rollback, chain selection or recovery plan.
