Qubic Dogecoin Attack Sparks Concerns After Monero Takeover

The Qubic community, known for pushing the boundaries of blockchain experiments, has chosen its next target. In a move reported by Cryptonews, members voted to launch a 51% attack against Dogecoin. The decision comes only days after the group gained majority control of the Monero network. With this step, Qubic has raised fresh concerns about the security of proof-of-work systems and the risks they face when mining power is concentrated.

From Monero to Dogecoin: A Sharp Escalation

Just last week, Qubic stunned the crypto industry by taking more than half of Monero’s hash rate. This allowed the group to reorganize six blocks—an outcome that closely mirrors the definition of a 51% attack. The mining pool behind the attempt now controls around 2.3 GH/s, making it the dominant player in Monero’s ecosystem.

Now, attention has turned to Dogecoin. The community chose it as the next target, moving from a smaller privacy-focused coin to one of the biggest and most well-known cryptocurrencies.

Why Dogecoin Was Chosen

After the Monero incident, Qubic founder Sergey Ivancheglo—better known as “Come-from-Beyond”—asked the community which blockchain they should target next. Options included Dogecoin, Kaspa, and Zcash. Dogecoin won the poll by a wide margin, collecting more than 300 votes.

The choice is significant. Dogecoin holds a market cap above $35 billion, placing it firmly among the world’s top digital assets. As a result, any attack against it would carry huge symbolic weight. It could expose risks like transaction censorship, block reordering, or even double spending.

Stress Test or Security Threat?

Supporters of Qubic describe these moves as “stress tests.” They argue the experiments showcase Qubic’s “useful proof-of-work” model, where mined coins are funneled back into token buybacks and burns. In their view, this is not about destruction but about highlighting weaknesses in existing systems.

Yet critics remain deeply skeptical. They caution that going after a big coin like Dogecoin wouldn’t just be a harmless experiment. It could make people lose trust in these networks and show how easily control can be concentrated in the hands of a few miners.

Industry Reaction and Fallout

The Monero takeover has already caused ripples. Kraken, one of the largest exchanges, suspended Monero deposits after the reorganization, citing network instability. Although trading and withdrawals continued, deposits remain paused until the chain is stable again.

Experts warn that if Dogecoin faces a similar threat, the impact would be far greater. A 51% attack could allow Qubic to rewrite history on the chain or prevent certain transactions from going through. For Dogecoin, which has millions of holders and high daily usage, such an event would be a major blow to trust.

What Comes Next?

So far, Qubic has not announced when or how it will begin targeting Dogecoin. Even so, the vote alone has sent a message. It has forced the crypto community to confront an uncomfortable truth: even the biggest and most popular blockchains are not immune to concentrated power.

The outcome of this campaign could shape how networks prepare for future threats. It could also push developers to rethink the security assumptions behind proof-of-work itself.
