This Altcoin Network Suffers Hack Attack, 3 Days of Trading at Risk! Exchanges Halt Trading!

As hacking incidents continue in the cryptocurrency market, hackers have this time targeted Ravencoin (RVN), an altcoin based on Proof-of-Work.

At this point, hackers created invalid blocks on the Ravencoin (RVN) network. The Ravencoin team acknowledged the hack, explaining that a critical consensus vulnerability on the network had been exploited, leading some nodes to accept invalid blocks.

While attackers managed to create invalid blocks by exploiting the flaw they discovered, the first known invalid block on the network, according to Ravencoin’s official statement, appeared on August 7, 2026 at 15:44:01 UTC with a height of 4,487,776.

This negative development has raised concerns that the network may face a blockchain restructuring deep enough to roll back approximately three days’ worth of transactions.

According to the statement, the 2Miners and RavenMiner mining pools currently control the majority of the network’s hash rate and have begun mining on an alternative chain, excluding the exploited branch, starting from a height of 4,487,776. If the miners who are said to dominate the network decide to allow this alternative chain to become dominant, the chain could be rolled back four days, returning to its state before August 7th, the date the attack began.

Such a deep reorganization could mean removing certain transactions from the blockchain history and re-executing them. This therefore poses a significant risk, particularly for deposit and withdrawal transactions on exchanges.

Therefore, the Ravencoin team recommended that exchanges temporarily suspend RVN deposits and withdrawals until the network stabilizes.

The project also reported that transactions verified after block number 4,487,775 should be considered at risk.

Following this development, exchanges such as Bithumb and Upbit temporarily suspended RVN deposit and withdrawal transactions. They also stated that a warning status was applied to RVN.

The security vulnerability in the network and the potential reorg risk directly impacted the RVN price. Ravencoin’s price dropped by approximately 20% within minutes of the news spreading.
