The research team at cryptocurrency exchange BitMEX has published an analysis of claims that a mining group called Qubic has gained majority control of the Monero (XMR) network.
According to information shared by BitMEX Research, a deliberate six-block reorganization (blockchain reorganization) believed to be caused by Qubic has been detected. This reorganization is relatively short, as the target block time on the Monero network is 2 minutes. Analysts noted that there was no evidence of a double-spend attack; rather, it was likely selfish mining aimed at obtaining higher block rewards.
Data shows that Qubic initially controlled approximately 20% of the Monero network, but has increased this share to over 30% through hashrate leasing. BitMEX noted that while Qubic hasn't reached a 51% majority, theoretically exceeding the 33% threshold could make selfish mining profitable as long as the coin's price remains stable.
