Monero Decentralization Crisis? Qubic Aims to Seize Monero's "51% Computing Power", Analyst: Sounding the Alarm for All PoW

Monero is facing unprecedented challenges! The Qubic platform, founded by IOTA co-founder Sergey Ivancheglo, is attempting to seize over 51% of Monero's Computing Power. (Background: Monero developers have launched the privacy chain Tari’s Mainnet, allowing $XTM Mining; how to participate?) (Additional context: Monero's market capitalization surged by $1.5 billion in a single day: why are hackers no longer interested in Bitcoin?) The privacy-centric cryptocurrency Monero is facing unprecedented challenges! The Qubic platform, founded by IOTA co-founder Sergey Ivancheglo, is attempting to seize over 51% of Monero's Computing Power. Monero faces a 51% attack crisis. According to MiningPoolStats data, Qubic’s share of Monero's global Computing Power has surged from less than 2% on May 18 of this year to over 27%, making it one of the largest Mining Pools for Monero. In response, Qubic's founder Sergey Ivancheglo publicly discussed on social media platform X, stating that to demonstrate the capability of Qubic's 'useful Proof of Work' (uPoW) mechanism, he plans to seize over 51% of Monero's Computing Power from August 2 to August 31, 2025. Sergey Ivancheglo announced his plan on X: Many people are asking how Qubic can maintain a continuous 51% Computing Power dominance over Monero, especially since 50% of Qubic’s mining time must be spent on Aigarth tasks. I initially responded, 'Let’s surprise the $XMR miners,' but later realized that the community would benefit from transparency, as XMR miners might find countermeasures and thus change strategies. Therefore, here is our next phase plan: . Enter stealth mode to make it infeasible to assess the real Computing Power through analyzing Qubic's network traffic. . Make the behavior of switching to XMR Mining unpredictable by any entity other than Dispatcher. . Isolate blocks from other miners. Like the Monero community, I am looking for countermeasures against Qubic's 51% Computing Power control. This is crucial for the cryptocurrency industry, as we all may face malicious attacks in the future. To raise awareness, starting with $XMR holders and then the broader audience, I recommend that Monero Mining Pools temporarily stop reporting their Computing Power to various sites. The Qubic Mining Pool will begin doing this next Wednesday. A lot of people were asking how #Qubic was planning to do sustained 51% domination over #Monero if 50% of Qubic mining time must be spent on #Aigarth tasks. First I was answering "Let's make a surprise to $XMR miners", but then I realized that the #cryptocurrency community would… — Come-from-Beyond (@c___f___b) July 25, 2025 What is Qubic? Founded in 2019, Qubic is an offshoot of the IOTA ecosystem. Its core feature is the 'useful Proof of Work' (uPoW) mechanism. Qubic has gathered significant Computing Power by rewarding miners for participating in Monero CPU Mining, while the Monero obtained from Mining is exchanged for stablecoins to repurchase and destroy its own tokens, creating a deflationary economic incentive mechanism. Sergey Ivancheglo’s plan has raised serious concerns in the Monero community regarding network decentralization and security. If Qubic controls over half of the Computing Power, it could refuse valid blocks from other Mining Pools, severely affecting the normal operation of the network. Analysts: This is a warning for all PoW networks In response to Sergey Ivancheglo's public call, the Monero community reacted strongly. However, Unstoppable Wallet analyst Dan Dadybayo pointed out that Ivancheglo has effectively created an 'incentive game' where Monero miners voluntarily relinquish network control due to higher rewards offered by Qubic. Dadybayo emphasized that Monero spends about $130,000 daily to maintain network security, but only requires an investment of $7,000 to $10,000 daily to potentially control most of the Computing Power. Therefore, this incident poses a threat not only to Monero but is, in fact, a warning for all PoW networks: Qubic claims 'we don't want to harm anyone,' but intentions don't matter. This is not just about vulnerabilities, but also about capital (incentive mechanisms). Relying solely on strong mathematics is insufficient; we need resilient, incentive-consistent infrastructure, or the next 'attack' could simply be a more profitable transaction. What is Monero? How terrifying is a 51% attack? Monero is a privacy-centric cryptocurrency that utilizes the RandomX Algorithm, emphasizing Anonymity and Decentralization, widely applied in transaction scenarios that require high levels of privacy. A 51% attack refers to a single entity or group controlling more than half of the Computing Power of a blockchain network, which could be used to reject blocks from other Mining Pools, delay transaction confirmations, or even perform Double Spending or force changes to the protocol, severely undermining the trust foundation of the network.
