Kraken has suspended Monero (XMR) deposits after detecting that a mining pool had gained control of more than half of the network’s total hashrate, raising concerns about centralization and network security, according to its status page.

Kraken is actively monitoring the situation and will resume deposits once it determines conditions are safe. Trading and withdrawals for Monero remain fully operational on the platform.

The pause came after Qubic mining pool, led by IOTA co-founder Sergey Ivancheglo, claimed to have achieved control over 51% of Monero’s hashrate, which could theoretically enable block reorganization, transaction censorship, or double-spending attacks.

Ivancheglo said in a statement that the move was intended to expose vulnerabilities and prepare the Monero community for future threats.

Looks like #Qubic has achieved 51% over #Monero, we are waiting for independent confirmations. In the meanwhile #Monero team is polishing details of their 51% attack protection.Many accused us of being sponsored by 3-letter agencies to attack this anon coin. What do you think…
