Kraken pauses Monero deposits following 51% attack

Kraken has temporarily paused Monero (XMR) deposits because a single mining pool, Qubic, gained more than 50% of the network's hashing power. Kraken said the concentration of mining power poses a potential risk to network integrity. Qubic, a layer-1 AI-focused blockchain and mining pool, claimed on Monday that it controlled the majority of Monero's hashrate and reorganized six blocks, which Monero community members denied. Qubic spokespeople said on Tuesday that the pool reached 51% after a month-long confrontation, following a DDoS attack on August 4 that reduced its hashrate from 2.6 GH/s to 0.8 GH/s, according to Sergey Ivancheglo.
