The Monero community ($XMR) faces a new debate on how to protect its network from possible 51% attacks, a scenario in which an actor controls the majority of the computing power and can reorganize blocks or censor transactions. The discussion arises after the initiative by Qubic, which claimed to have secured a significant portion of Monero's hashrate.
Among the proposals analyzed are: locating mining equipment, adopting merged mining (allowing Monero to be mined alongside other cryptocurrencies), and applying ChainLocks, a mechanism already used in Dash that uses randomly selected masternodes to lock the ledger and prevent reorganizations, even if someone concentrates greater computing power.
The perception of what happened varies. While some users argue that Qubic did not take full control but rather carried out a limited reorganization, data from MiningPoolStats indicates that this pool reached 2.39 GH/s, the largest in the network.
The market reaction was clear: Kraken temporarily suspended XMR deposits and then resumed them with a higher requirement for confirmations, citing uncertainty about the security of the network. For some researchers and analysts, the episode had more to do with media strategy than a real threat, recalling the constant challenges of balancing innovation, security, and trust in decentralized systems.
