Catenaa, Friday, August 22, 2025- The Monero network is exploring changes to its proof-of-work consensus mechanism following a reported 51% attack by the Qubic mining pool.
The community is considering options including localized mining hardware, merge mining alongside Bitcoin, or adopting Dash’s ChainLocks system to secure the blockchain against majority-hash attacks.
ChainLocks employs randomly selected masternodes to verify the first valid block and lock the ledger, preventing reorganizations even if a malicious miner holds more accumulated proof-of-work.
Dash DAO core member Joel Valenzuela warned that ASIC-resistant chains remain vulnerable to economic-based attacks, highlighting the need for integrated safeguards.
Qubic currently commands 2.18 gigahashes per second, making it the largest Monero mining pool, followed by Supportxmr at 1.18 GH/s.
While some Monero users dispute that Qubic achieved majority control, Kraken temporarily suspended Monero deposits, later reinstating them with a 720-confirmation requirement to protect users.
The attack prompted Qubic to vote on targeting Dogecoin next, securing over 300 community votes.
Founder Sergey Ivancheglo clarified that DOGE mining requires development and the pool is focused on Monero for now.
Monero’s community remains divided over the severity of the attack, but discussions on consensus modifications signal heightened awareness of network security risks.
