The post Qubic signs 63 blocks out of 122 appeared on BitcoinEthereumNews.com.

August 11, 2025: the pool linked to Qubic has surpassed the critical threshold in some operational windows on Monero, reaching 63 blocks out of 122 and causing a reorganization (reorg) of up to 6 blocks. Following the event, some exchanges – including Kraken – have prudently suspended deposits in XMR, while the community has accelerated the migration towards P2Pool. For details of the event in the media and for the technical context, see also the journalistic reconstruction and the literature on the phenomenon of selfish mining: the academic reference study on the subject Eyal & Sirer (2014). According to the data collected by our on‑chain monitors and public dashboards (for example xmrchain and MoneroBlocks), in critical windows the pool reached a hashrate share consistent with 51.6% calculated over the 122 block window. We have verified dozens of orphan blocks and multiple reorgs up to 6 blocks; the same indicators show that the pressure on hashpower allocation was concentrated in discontinuous intervals rather than continuous. Data updated as of August 27, 2025. What happened, in brief 51% threshold exceeded: in certain operational windows, the Qubic pool concentrated the majority of the hashrate and published a private chain to the detriment of the main network. Deep reorganizations: up to 6 blocks replaced, with dozens of blocks left orphaned (stale). Immediate impact: deposits in XMR suspended or slowed down on various exchanges and increase in confirmation requirements. Economic dynamics: external incentives through buyback & burn of QUBIC have channeled a significant share of hashpower to Monero. Spillover risk: the Qubic community has already indicated the intention to focus, in a subsequent phase, on Dogecoin – a PoW network with, according to updated market data, a market capitalization of about 35 billion dollars as of August 27, 2025. Who is Qubic and why its…
