According to @BitMEXResearch, Monero (XMR) may have experienced a deliberate 6-block chain reorganization tied to Qubic mining. @BitMEXResearch noted that with Monero’s 2-minute target block time, the reorg spanned roughly 12 minutes and was described as small. @BitMEXResearch added it is not clear whether a double-spend occurred or whether the event reflected selfish mining behavior.
