The Monero community is proposing changes to its proof-of-work (PoW) consensus mechanism to enhance resistance against 51% attacks. Suggested solutions include localizing mining hardware, transitioning to a merge mining algorithm, and implementing a system similar to Dash’s ChainLocks, which utilizes randomly selected masternodes to confirm the validity of blocks, thereby securing the blockchain against reorganizations even from miners with higher accumulated power. The recent emergence of the Qubic mining pool, which controls the highest hashing power on Monero, has raised concerns about potential network vulnerabilities. Kraken, a major crypto exchange, has warned about possible deposit halts due to uncertainties regarding Monero’s security amid significant hash rate concentration. Despite the apprehensions, some community members disagree that Qubic achieved majority control, claiming only minor block reorganizations took place. Amid discussions, Qubic's community has also set sights on mining Dogecoin as its next target, having received significant support within the community, while the pool continues its focus on Monero mining.
