Monero at Risk: Qubic Allegedly Controls Majority Hash Rate Enabling 51% Threat

I’m alarmed by reports that the Qubic mining pool has taken control of most of Monero’s hash rate, effectively enabling a large-scale blockchain reorganization. If accurate, this dominance would let an attacker rewrite chain history, execute double-spend attacks, and censor transactions across the Monero network.

The founder of SlowMist flagged Qubic’s apparent takeover of the majority hash power, and Ledger’s CTO has estimated that sustaining such an attack could cost roughly $75 million per day. Experts are warning that this level of control represents a severe threat to Monero’s network security and consensus integrity.
