The industry is facing renewed concerns over blockchain security as the Qubic community, led by Sergey Ivancheglo (also known as “Come-from-Beyond”), sets its sights on Dogecoin. This move follows Qubic’s controversial claim of achieving majority control over Monero’s hashrate earlier this month, an attack that shocked the digital asset space and reignited debate about Proof-of-Work (PoW) vulnerabilities.
With Dogecoin now declared as Qubic’s next target, the development has raised questions about whether even the largest and longest-standing PoW networks remain at risk from coordinated efforts to dominate their computational infrastructure.
From Monero to Dogecoin: A Strategic Escalation
Qubic’s recent 51% takeover of Monero’s network marked a turning point for blockchain security discourse. By pooling resources, the group claimed to have captured more than 77% of Monero’s hashrate, effectively controlling block validation and proving that majority attacks are not merely hypothetical.
Ivancheglo described the Monero operation as both a demonstration of strength and a wake-up call for the broader industry. He argued that the incident forced Monero developers to accelerate their defenses, showing that only direct confrontation could spur meaningful improvements in resilience.
Now, following a community vote on Discord, Qubic has identified Dogecoin as its next objective. This represents a significant escalation. Unlike Monero, which focuses heavily on privacy and employs a CPU-friendly mining algorithm, Dogecoin operates within a far larger ecosystem and is secured through merge-mining with Litecoin.
Why Dogecoin Represents a Different Challenge
Targeting Dogecoin brings an entirely new level of complexity compared to Monero. Dogecoin is secured by the Scrypt algorithm and benefits from merged mining with Litecoin, meaning the combined security of both chains acts as a safeguard.
As of August 18, 2025, Dogecoin’s hashrate was measured at approximately 3.47 petahashes per second (PH/s), while Litecoin contributed an additional 2.78 PH/s. Together, their combined computational strength dwarfs Monero’s network by more than a million times.
A Qubic ambassador, known online as “QubicChurch,” acknowledged this vast disparity, emphasizing that any attempt to influence or overpower Dogecoin’s network would require months of preparation and unprecedented resource allocation. The ambassador also noted that achieving even a fractional share of Dogecoin-Litecoin’s hashrate would represent more raw power than Monero’s entire system many times over.
Implications for the Industry
The reveal of Qubic’s new target has triggered a wave of responses from analysts and industry participants. Many view it as both a symbolic and practical test of blockchain resilience. Unlike smaller PoW systems, Dogecoin’s reliance on merged mining with Litecoin provides it with an added layer of protection, making any attempt at a hostile takeover far more challenging and costly.
Yet the significance of Qubic’s move extends beyond technical feasibility. By deliberately selecting high-profile networks, the group appears to be making a statement about the vulnerabilities that exist across decentralized systems, regardless of their scale. For some, this raises an uncomfortable question: if even larger networks can be openly challenged, how secure are the countless smaller PoW projects that lack similar defenses?
The possibility of capturing even a small fraction of Dogecoin’s hashrate, according to Qubic supporters, would not only showcase their dominance but also generate substantial financial flows into their ecosystem. For critics, however, the group’s ambitions amount to destabilization that risks undermining trust in blockchain technology.
Lessons From Monero’s Experience
The Monero community continues to assess the aftermath of Qubic’s claimed 51% control. While some argue that the incident highlighted genuine vulnerabilities, others believe it exaggerated Qubic’s actual capabilities. Regardless, Monero developers were reportedly prompted to fast-track updates aimed at strengthening network resilience.
For Dogecoin, the situation serves as both a warning and a case study. Unlike Monero’s CPU-oriented RandomX algorithm, Dogecoin’s reliance on ASIC mining and its symbiotic relationship with Litecoin create a very different security profile. Experts suggest that this structural difference may deter attackers by raising costs to unsustainable levels. However, the fact that Qubic is openly preparing to attempt such a move underscores that no network can be considered beyond reach.
The Road Ahead
The prospect of Qubic directing resources against Dogecoin has surge both skepticism and concern. While many doubt that the group can marshal the massive resources required to meaningfully disrupt Dogecoin’s network, the publicity surrounding the effort alone could create uncertainty in markets.
More broadly, the campaign illustrates the evolving landscape of blockchain security. As digital assets grow in scale and visibility, so too do the motivations for groups to test their limits. The industry may need to adopt new defensive frameworks, whether through stronger consensus mechanisms, more robust mining incentives, or alternative forms of decentralization.
For now, Dogecoin continues to operate normally, bolstered by its connection to Litecoin’s mining infrastructure. But the spotlight from Qubic’s challenge ensures that its security model will face heightened scrutiny in the months ahead. Whether this effort ultimately strengthens or destabilizes confidence in PoW networks remains to be seen.
Conclusion
Qubic’s declaration of intent to target Dogecoin marks one of the most significant stress tests for a major Proof-of-Work network in recent years. While Monero’s experience demonstrated that theoretical vulnerabilities can manifest in practice, Dogecoin’s scale and merged mining foundation create an entirely different challenge.
Still, the underlying message from Qubic’s campaign is clear: no blockchain is immune to attack. As the group prepares for its next move, developers, miners, and communities across the digital asset ecosystem are being reminded that security must remain a constant priority — not only in code but also in collective vigilance.
