Ravencoin Halts Deposits After Consensus Flaw Lets Invalid Blocks Through
Security & Exploits ·
A software bug allowed faulty blocks onto the Ravencoin chain, pushing the network toward a rollback of several days of activity and prompting exchanges to pause RVN transfers.
Ravencoin disclosed that a flaw in its consensus rules was exploited, letting some nodes accept blocks that should have been rejected, with the earliest tainted block recorded at height 4,487,776, according to wublockchain.xyz. Two mining operations, 2Miners and RavenMiner, are now assembling a separate chain built on top of the last clean block, 4,487,775, in an effort to route around the compromised branch.
Should that alternative chain gain more work than the tainted one, the network would revert to before the bug appeared, undoing an estimated three days of confirmed transactions. Ravencoin urged exchanges to pause RVN deposits and withdrawals in the meantime and to treat any transfers recorded after block 4,487,775 as liable to be undone once the rollback resolves.
Other outlets tracking the incident describe a steeper rollback window: coindesk.com reported that the network may need to erase roughly four days of transactions rather than three, while leviathan.news also framed the pool coordination as a forced rollback effort tied to the same exploit. Market reaction has been sharp, with decrypt.co noting a price decline tied to the disclosure, and separate reporting in the same cluster citing drops as steep as 20% and 17% following the news.
The discrepancy between three-day and four-day rollback estimates has not been reconciled across the available reports, and it remains unclear whether the 2Miners and RavenMiner chain has yet overtaken the affected branch in cumulative work. Also unresolved is how long exchanges will keep RVN deposits and withdrawals frozen, and what technical fix, if any, Ravencoin plans to deploy to close the consensus gap that allowed the invalid blocks to be accepted in the first place.
