# Zabby Starchaser No, a 51% attack doesn't allow them to de-anonymize...

*August 12, 2025 — Comment Archer T. Ships replied to Zabby Starchaser's comment.*

Zabby Starchaser No, a 51% attack doesn't allow them to de-anonymize Monero transactions. If a mining group controls over half of Monero’s hashrate, they can: * Double-spend coins (reverse recent transactions they sent). * Censor transactions by refusing to include them in blocks. * Reorganize the blockchain to some extent. They cannot: * Break Monero’s ring signatures, Stealth Addresses, or RingCT encryption. * Retroactively deanonymize past transactions.
