Qubic’s mining group has picked Dogecoin as its next target after claiming it briefly gained majority control of Monero’s network, according to reports.

The group said it reorganized six blocks on Monero and then asked its community to vote on which ASIC-friendly proof-of-work coin to test next. The vote came on Aug. 17.
Community Picks Dogecoin
Based on reports, Dogecoin won the vote with more than 300 votes. Qubic’s founder, Sergey Ivancheglo, shared that Dogecoin beat out Zcash and Kaspa in a public poll.
The project says its Monero pool reached a 51% share and that it currently runs about two point three GH/s of Monero hashrate.
The group calls these moves “stress tests” and says they are meant to show how its mining model works, while also using pool profits to buy and burn QUBIC tokens. The group added it does not want to destroy networks.

The technical claim has sparked debate in the Monero community. Some developers and miners question whether the pool ever held sustained, uncontested control.
Others say the actions — which reorganized blocks — are proof the group can alter short stretches of chain history. Either way, the interruption was enough for Kraken to pause Monero deposits while exchanges and services assessed risk.
What A 51% Attack Can Do
A 51% attack lets the controller reorganize blocks or stop transactions. A group that controls more than half of a network’s mining power can rewrite recent blocks, halt certain transactions, or try double-spends.
Qubic’s move showed it could force a small reorg on Monero. If a similar level of control were applied to Dogecoin, the effect could be larger because Dogecoin has a market capitalization above $35 billion.
Still, Dogecoin benefits from merged-mining with Litecoin and runs at a much higher hashrate, so an attack would likely cost far more.
Markets and exchanges reacted quickly. Prices moved on the news and custodial services tightened checks.
Kraken’s decision to pause deposits underscored how exchanges will act fast when block reorgs or other threats appear. Users and traders faced increased short-term uncertainty.

What To Watch Next
Based on reports, the timeline is unclear but the issue raises bigger questions. Qubic has not given a clear timeline for any action against Dogecoin.
Observers will watch for technical logs, more statements from the project, and any responses from Dogecoin and Litecoin developers.
A Hostile Act?
People will also be looking for proof that Qubic’s tests were non-destructive and for evidence about how long the pool actually held control.
Most outlets call what Qubic did a 51% attack (a chain reorg), not a “hack” in the usual sense — but it’s still an attack on network consensus and many people treat it as hostile.
