Qubic Reveals 51% Attack Risk for Monero

Reports indicate Qubic mining pool now controls most of Monero’s hash rate, raising a 51% attack risk. Experts warn of possible blockchain reorganizations, double-spends, transaction censorship and a $75M/day maintenance cost—posing a major threat to Monero network security.

I warn that Qubic may control a majority of Monero's hash rate, creating a potential 51% attack risk. Reports from SlowMist and comments from Ledger’s CTO (estimated $75M/day to sustain the attack) highlight serious threats including blockchain reorganizations, double-spends and transaction censorship. Monitor Monero network security and update positions accordingly.

I question Qubic's claimed Monero mining power ratio — the asserted share of Monero hash rate looks doubtful and is hard to verify, raising concerns about mining centralization and transparency.

Rumors are circulating about a potential 51% attack on Monero (XMR). I’m monitoring network metrics, pool concentration, and developer updates while advising caution on large XMR transactions until the situation is verified.

Monero (XMR) fell over 17% after exchanges suspended deposits and withdrawals amid reports Qubic controls ~52% of hashrate, raising 51% attack, double-spend and censorship concerns.

I’m alarmed by Qubic’s claim of majority control over Monero’s hashrate—this centralization raises the risk of a 51% attack and highlights critical Monero (XMR) network security concerns. Monitor hashrate distribution and chain health closely.

I’m warning that Qubic’s claim of majority Monero hashrate control could enable a 51% attack, undermining network security, decentralization, and user trust in XMR.

I report that Monero appears to be under a successful 51% attack by Qubic mining pool, enabling chain reorgs, double spends, and transaction censorship. Platforms should monitor the network and consider defensive steps.

I report that Monero (XMR) appears to be suffering a 51% attack by Qubic pool, enabling chain reorganizations, double spends, and transaction censorship. The attack is costly (est. $75M/day), so its long-term economics are uncertain — platforms should monitor XMR closely.

I report that the Qubic mining pool appears to have executed a 51% attack on Monero, controlling most hashrate and triggering a major chain reorg. This dominance allows double-spend, censorship, and rewriting history, with an estimated $75M/day to sustain the attack.
