Qubic Seizes Monero Hashrate: 51% Risk and Major Security Concerns

I’m reporting that the mining pool Qubic appears to have captured the bulk of Monero’s hash rate, effectively enabling a 51% attack and large-scale blockchain reorganizations. With that level of control, the pool could potentially rewrite transaction history, execute double-spend attacks, and censor or block transactions on the Monero network.

I’m also noting Ledger’s CTO’s estimate that sustaining such an attack could cost on the order of $75 million per day, highlighting both the scale and the severity of the threat. Security professionals are warning that this concentration of mining power represents a significant risk to Monero’s network security and the integrity of its privacy-focused transactions.
