TL;DR
- Ravencoin could execute a four-day roll back after a critical flaw allowed the insertion of invalid blocks into its network.
- Pools 2Miners and RavenMiner, which control most of the hashrate, are rebuilding the chain from block 4,487,775, prior to the exploit.
- Bitvavo and Upbit suspended RVN deposits and withdrawals; the token fell 17% in 24 hours to approximately $0.0029.
Ravencoin could revert up to four days of transaction history after attackers exploited a critical flaw in its software that allowed the insertion of invalid blocks into the network. The project confirmed the incident, in what represents one of the most serious attacks in its history.
The blockchain was launched in 2018 as a fork of Bitcoin’s code, designed primarily for the issuance and transfer of digital assets. Its network is considerably smaller, which gives a handful of mining pools a determining influence over which version of the chain prevails when a split occurs.
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.…

Ravencoin: Four Days of History at Stake
The first invalid block appeared at height 4,487,776 at 15:44 UTC on August 7. Once the vulnerability was exposed on the production network, other attackers replicated the exploit and began generating their own invalid blocks. The project published a patch, but fixing the software does not revert what was already written on the chain.
The two pools with the greatest computing power on the network, 2Miners and RavenMiner, chose to rebuild the chain from block 4,487,775, the last valid block before the attack. The project asked them to restart from a more recent point to minimize the history at risk, but both rejected the proposal. RavenMiner reported on its website that its nodes are already running an emergency fix and that it will mine the clean chain, discarding all blocks produced during the attack. The firm paused payments until the situation stabilizes and promised to cover any difference with its own funds.
What Happens to Exchanges and Users
The most direct consequences fall on exchanges and users with open transactions during that period. A payment completed over the weekend could disappear from Ravencoin’s records, returning the coins to the sender and leaving the recipient with nothing. Exchanges that credited deposits and allowed withdrawals on that basis are exposed to losses.
Bitvavo suspended Ravencoin deposits and withdrawals citing the detected vulnerability. South Korean exchange Upbit placed an investment warning on RVN across its won, bitcoin and tether markets, and also halted deposits. The token RVN fell 17% in the last 24 hours to approximately $0.0029, reducing its market capitalization to around $48 million with a volume of $10 million. Over the past year, the token has accumulated a decline of 77%.
This is not the first time Ravencoin has dealt with an incident of this magnitude. In 2020, attackers exploited a flaw that allowed the creation of approximately 31 million RVN tokens above the limit established by the protocol, before the issue was corrected.
