Qubic Team Successfully Executes 51% Attack on Monero

3 Min Read Tags:

  • Qubic mining pool reportedly gained over 53% control of Monero’s network, sparking concerns about potential block reorganizations and transaction censorship.
  • The value of XMR dropped by 8%, while QUBIC’s price increased by 4% amidst these developments.
  • Concerns persist over the legitimacy and implications of the alleged 51% attack by Qubic on Monero.
  • Skepticism remains within the crypto community about the actual success of this attack, with some suggesting it might be a result of luck rather than strategic dominance.

Qubic Executes a Successful 51% Attack on Monero Network

The recent assertion that Qubic successfully executed a 51% attack on the Monero network has sent ripples through the cryptocurrency world. This audacious move, which reportedly allowed Qubic to take control of over half of Monero’s hash rate, has raised alarms regarding potential block reorganizations and transaction censorship. As a result, the value of Monero (XMR) experienced an 8% decline.

Debate Over Qubic’s Hash Rate Dominance

Despite claims from SlowMist founder Yu Jian that Qubic managed to surpass a hash rate share of 52.36%, alternative reports suggest it exceeded even further to above 53%. However, some community members argue that these figures might be overstated. The CTO of Ledger, Charles Guillemet, highlighted that maintaining such dominance incurs daily costs around $75 million, casting doubt on its economic viability.

Skepticism Surrounding Attack Success

Questions linger regarding whether Qubic’s purported attack truly succeeded. Leading SeraiDEX developer Luke Parker noted that if Qubic had genuinely monopolized Monero’s hash rate, no blocks from other miners would exist. Instead, some speculate that favorable circumstances or sheer luck may have played a significant role.

Repercussions in the Crypto Market

These developments have notably impacted cryptocurrency prices: while XMR saw an 8% dip, the value of QUBIC rose by 4%. This price fluctuation underscores market sensitivity to network security concerns and the strategic maneuvers within major mining pools.

The Economic Experiment Behind the Move

Qubic’s strategy involves rewarding miners with their native tokens to attract operators into their pool—a move described as an “economic demonstration” rather than malicious intent according to Sergey Ivancheglo, head of Qubic and co-founder of IOTA.
As this controversial experiment is expected to continue until August 2025, it remains under close scrutiny from both supporters and critics within the crypto community. The broader implications for blockchain networks emphasize the delicate balance between technological innovation and security vulnerabilities in decentralized systems.
