This week’s crypto headlines were dominated by security threats, major protocol upgrades, and institutional moves into new assets. Here are the key developments.
Qubic Pool executes 51% attack on Monero
The Monero network suffered what appears to be a successful 51% attack by Qubic mining pool. On Tuesday, a major blockchain reorganization was detected after Qubic seized majority hashing power, allowing it to censor transactions and conduct double-spending. Reports show six blocks were reorganized and 60 orphaned, with nearly 750 XMR mined in two hours. Qubic framed the attack as a planned experiment, redirecting computing power from its decentralized AI platform. Analysts noted Monero’s small hashrate made the network vulnerable compared to larger PoW chains.
