Monero Faces Largest Blockchain Reorganization, Invalidating Transactions
- Monero’s network experienced an unprecedented reorganization of 18 blocks, erasing approximately 36 minutes of transaction history.
- A total of 118 transfers were invalidated due to the rollback initiated by mining pool Qubic.
- The incident is linked to Qubic’s withheld mining and potential majority hash control, following a previous attempt at a 51% attack.
- Despite the rollback, Monero’s native token XMR showed resilience, increasing over 5% on the day and nearly 12% for the week.
This significant blockchain reorganization highlights vulnerabilities in Monero’s network regarding concentrated mining power and its impact on transaction finality. The event has prompted exchanges to reassess their confirmation requirements for Monero transactions.
The rollback demonstrated that existing security measures might not be sufficient, as payments once considered final were erased due to Qubic’s strategic mining activities. This incident underscores the need for enhanced security protocols within decentralized networks to prevent similar occurrences in the future. Source
