The Monero network recently experienced a significant blockchain reorganization, effectively erasing 36 minutes of transaction history. The event, which occurred due to a chain split, resulted in the removal of 118 transactions from the ledger. This incident has been linked to the mining pool Qubic, whose computational power contributed to the chain reversal. The reorganization has reignited longstanding concerns within the cryptocurrency community regarding the risks of selfish mining, a practice where a miner or pool with substantial hash rate advantage can manipulate the blockchain for potential gain. While the network has since stabilized and continued normal operations, the event underscores the ongoing challenges proof-of-work networks face in maintaining chain integrity against concentrated mining power. The Monero development team has not issued an official statement regarding potential protocol changes in response to this event.
