Ravencoin Faces Potential Rollback of Transactions Due to Software Flaw

Ravencoin is at risk of rolling back transactions made over the past four days due to a critical software flaw that permitted invalid blocks to be added to its blockchain. Two mining pools, which collectively account for a significant portion of Ravencoin’s hash power, are in the process of creating a replacement chain starting from the last valid block recorded before the issue arose.

Details of the Flaw

The vulnerability was identified after the first invalid block emerged on August 7 at block height 4,487,776. Following this occurrence, other miners began exploiting the flaw by generating their own invalid blocks, further endangering the integrity of the network.

Implications for Users and Services

As a result of this situation, transactions that were processed during the affected period could be erased from Ravencoin’s history, posing a significant risk to payments, deposits, and withdrawals made over the weekend. Ravencoin informed users and exchanges that they should not assume that any transactions that may disappear will simply return to the network. As a precautionary measure, several exchanges have already halted RVN deposits and withdrawals.

Mining Pools’ Response

Both mining pools, 2Miners and RavenMiner, are commencing their blockchain reconstruction from block 4,487,775. Although Ravencoin has released a fix for the flaw, they requested the pools to minimize the rollback period to lessen the impact on user transactions; this request was ultimately declined.

Market Impact and Future Outlook

In light of the developing situation, the price of RVN fell by 17% in a 24-hour period, bringing its value down to approximately $0.0029 and reducing its market capitalization to around $48 million. The token has experienced a substantial decline of 77% over the past year. Ravencoin’s threshold for blockchain manipulation raises concerns reminiscent of a similar incident in 2020, when a flaw in the system allowed the creation of approximately 31 million excess tokens.
