The cryptocurrency world has been shaken by claims from Qubic, a project led by IOTA co-founder Sergey Ivancheglo, that it has allegedly seized majority control of the Monero blockchain\u2019s<\/a> hashrate. According to the team, this milestone was reached on August 11, 2025, after a focused push that lasted several weeks. The development has opened up concerns over Monero\u2019s network security and the vulnerability of mid-cap Proof-of-Work blockchains to incentive-driven takeovers.<\/p>\n

How Has The Monero Situation Played Out?<\/h2>\n

According to the Qubic team<\/a>, the attack was carried out using a \u201cuseful proof\u2011of\u2011work\u201d (uPoW or UPoW) model. Miners channel their CPU mining power toward Monero; Qubic then converts the mined XMR into USDT to buy and burn QUBIC tokens or reward its own validators. This economic design drew a substantial portion of the Monero mining power away from other pools, escalating from under 2% in May and culminating in the claimed 51% threshold by August. Qubic describes this as a strategic experiment not intended to destroy Monero but to test how incentives can be used to shift control over a network.<\/p>\n

According to reports and mentions on the social media platform X, there was indeed a six-block reorganization on the Monero blockchain, which showed that Qubic does control a large enough hashrate.<\/p>\n

If Qubic succeeded in gaining and sustaining majority control (over 50%) of the blockchain\u2019s hashrate, the implications could be severe. In such a scenario, Qubic could potentially censor transactions, perform double-spends, and reorganize blocks at will. Such power would allow them to reverse confirmed transactions and undermine the blockchain\u2019s integrity.<\/p>\n

What Have Experts Said?<\/h2>\n

In response, the Monero developer community noted that chain reorganizations alone don\u2019t confirm a true 51% attack. Luke Parker (lead dev at SeraiDEX) stated that a six\u2011block\u2011deep network reorg with block orphaning does not mean a 51% attack was successful.<\/a> However, it does mean a mining group with a high amount of hashrate got lucky.\u00a0<\/p>\n

The CTO of Ledger, Charles Guillemet, also raised alarms<\/a> regarding the incident. Guillemet warned that sustaining such a dominance could cost $75 million per day in equipment and operations, and that even that might compromise confidence in Monero nearly instantly.<\/p>\n

Indeed, many in the Monero community are skeptical that <\/a>Qubic truly sustained such control. According to a post by blockchain engineer Leonardo Faoro, which was also reposted on the social media platform X by Monero founder Riccardo Spagni, miners don\u2019t need a full 51% hashrate<\/a> to trigger reorgs. They only require about 35% of the hashrate, along with fortunate timing.<\/p>\n

Monero\u2019s market performance quickly reflected the unease in the hours following Qubic\u2019s claim of majority control. This unease saw its price fall to as low as $245. At the time of writing, Monero is trading at $247, down by 5.3% and 15.2% in the past 24 hours and seven days, respectively.<\/p>\n

Qubic\u2019s native token, on the other hand, experienced the opposite trajectory. At the time of writing, QUBIC is up by 20.5% in the past 24 hours.<\/p>\n
