Qubic Group Targets Dogecoin After Monero 51% Block Reorg
On August 17, Qubic Group’s mining pool briefly achieved over 51% hashrate on Monero, executing a six-block reorganization as a proof-of-concept 51% attack. The community then voted to target Dogecoin over Zcash and Kaspa in its next ASIC-friendly 51% attack stress test. Qubic founder Sergey Ivancheglo says these tests validate the pool’s useful PoW model and fund QUBIC token buybacks. After Monero’s block reorg, exchanges like Kraken paused XMR deposits, highlighting security concerns. Although Dogecoin’s merged-mining with Litecoin and higher hashrate make a similar attack costlier, traders should monitor technical logs, developer responses, and any timeline for action. The move underscores risks of mining centralization and potential market confidence impacts for DOGE.
Bearish
The news of a successful 51% attack on Monero and the announcement of Dogecoin as Qubic Group’s next stress test target is bearish for DOGE. In the short term, heightened security concerns and the potential for a similar block reorg or double-spend attack may undermine trader confidence, leading to selling pressure. Exchanges’ precautionary measures after the Monero incident further amplify market anxiety. In the long term, Dogecoin’s merged-mining with Litecoin and its larger hashrate increase the cost and complexity of a 51% attack, which may eventually restore confidence if no breach occurs. However, the event spotlights the broader risks of mining centralization in proof-of-work networks, keeping risk-averse traders cautious.
