Qubic exceeds 51% of the hash rate and demonstrates the real power of Useful Proof of Work
Recently, Qubic reached more than 51% of the hash rate and highlighted how a group with enough computing power can temporarily dominate Monero, the privacy-focused cryptocurrency that uses the ASIC-resistant RandomX algorithm. The demonstration used a tactic known as Selfish Mining, a strategy studied in academic literature that shows how a pool with a relatively high hash rate can obtain a disproportionate share of block rewards. This event underscores risks for PoW networks and the need for continuous vigilance by developers and the community.
The implications for Monero and other chains that prioritize privacy are relevant both in technical and governance terms. Although the demonstration illustrates a plausible attack vector under laboratory or test conditions, it does not intend to explain or facilitate the replication of attacks in real environments. Instead, it encourages discussions about mitigations, protocol updates, and continuous audits by researchers and development teams.
