Qubic announced that it reached over 51% of Monero's hashrate in an experiment designed to help secure the network against future attacks. The company’s X post and blog detailed that within a selected window, it mined 63 of 122 blocks, effectively demonstrating majority control. While some experts observed network reorgs and potential manipulation, others questioned the evidence and the sustainability of the takeover. The experiment comes amid a significant market downturn for Monero, which has dropped nearly 25% over the past month, intensifying concerns about blockchain vulnerabilities.
