Qubic Targets Dogecoin After Monero 51% Attack

The Qubic blockchain project, led by founder Sergey Ivancheglo (aka Come-from-Beyond), has voted to make Dogecoin (DOGE) its next target after successfully executing a 51% attack on Monero (XMR) earlier this week.

From Monero to Dogecoin

Qubic’s community poll asked members which ASIC-enabled, proof-of-work blockchain to attack next. The options included Dogecoin, Kaspa, and Zcash. Dogecoin received over 300 votes, more than all others combined, cementing it as Qubic’s next objective.

This comes just days after Qubic claimed hashrate dominance over Monero, reorganizing six blocks and forcing crypto exchange Kraken to temporarily suspend Monero deposits due to risks of network manipulation.

Why a 51% Attack Matters

A 51% attack occurs when a single entity controls more than half of a blockchain’s computing power. With this control, attackers can:

• Reorganize blocks
• Double-spend coins
• Block other miners from validating transactions

While Qubic claims Monero’s “privacy, speed, and usability” remain intact, the successful takeover highlights vulnerabilities in proof-of-work blockchains where hashrate is concentrated.

What It Means for Dogecoin

With a market cap above $35 billion, Dogecoin is one of the largest proof-of-work cryptocurrencies. A successful attack could:

• Damage its reputation as a secure blockchain
• Trigger significant price volatility
• Undermine user trust and adoption

Analysts note this is not just about Dogecoin, but a broader reminder that proof-of-work networks must maintain decentralization to remain secure.
