Qubic Community Votes to Target Dogecoin with Potential 51% Attack After Monero Incident
August 18, 2025: The cryptocurrency ecosystem is facing renewed security concerns as the AI-focused blockchain project Qubic announced plans to launch a 51% attack on Dogecoin (DOGE), following its recent control over Monero’s mining power.
The move was confirmed after a community poll led by Qubic founder Sergey Ivancheglo, who asked participants which ASIC-mined Proof-of-Work (PoW) blockchain should be their next target. Dogecoin received over 300 votes, surpassing combined votes for competitors Kaspa and Zcash, signaling the community’s intention to disrupt one of the crypto market’s most popular coins.
Dogecoin, a meme-inspired cryptocurrency with a market capitalization exceeding $35 billion, has gained mainstream attention and backing from prominent figures like Elon Musk. However, its PoW consensus mechanism remains vulnerable to such attacks, which could destabilize network transactions and undermine user trust.
Background: Qubic’s 51% Attack on Monero
Qubic previously stunned the crypto community by achieving majority control (over 51%) of Monero’s global hashrate, allowing it to reorganize blocks, censor transactions, and attempt double-spending on the privacy-focused blockchain. This was framed by Ivancheglo as a stress test but prompted swift backlash and notable harm to Monero’s price and reputation.
Following this, crypto exchange platforms, including Kraken, temporarily halted Monero deposits, citing potential risks associated with network integrity. The incident highlighted the fragility of Proof-of-Work systems when a single entity or coalition gains disproportionate hash power.
The Implications for Dogecoin
Experts warn that if Qubic executes a successful 51% attack on Dogecoin, similar consequences could follow, including transaction censorship, double-spending, and potential disruption of consensus. This would pose a significant risk to investors and holders of DOGE, who may see increased volatility and loss of confidence.
Dogecoin’s price has already reacted negatively to the announcement, slipping approximately 4% and approaching a critical support level of $0.21. On-chain data shows increased bearish sentiment, with more holders registering losses and rising short positions among traders.
Community and Industry Response
The growing threat from Qubic has reignited debates on the need for greater decentralization and security in PoW networks. Industry voices argue for proactive measures to safeguard against such attacks, including mining decentralization, network upgrades, and developer vigilance.
Qubic’s approach—deploying community-driven decisions to select attack targets—raises fundamental questions about the resilience of cryptocurrencies that rely heavily on mining power. As the blockchain industry watches closely, the focus currently centers on Dogecoin’s ability to defend against the impending threat.
Conclusion
The Qubic project’s targeting of Dogecoin follows a disruptive pattern seen with its attack on Monero. The crypto community now faces immediate challenges to fortify network defenses to preserve the integrity of popular Proof-of-Work blockchains amid evolving coordinated threats.
