Monero (XMR) defied the odds on Sunday, climbing more than 7% even after its blockchain experienced one of the largest reorganizations in its history. The 18-block reorg reversed roughly 117 transactions and renewed concerns about the growing influence of Qubic, a layer-1 AI-focused blockchain and mining pool.
Reorg Details and Confirmation
The reorg began at block 3499659 at 05:12 UTC and finished at block 3499676 about 43 minutes later. Community node operators and researchers, including Rucknium, validated the event. Qubic — already linked to a prior six-block reorg — now controls over 51% of Monero’s hashrate, enabling deep chain reorganization.
Price Reaction and Community Response
Despite the breach, XMR rallied from about $287.54 to $308.55 (≈ +7.4%) within hours while the broader market slipped. The episode split opinion: some observers speculated Qubic acted to stabilize price, while others, like analyst Vini Barbosa, said they would stop accepting XMR until security improves.
Centralization vs. Security Trade-offs
Potential defenses include adopting DNS checkpoints or other client-level protections — approaches that introduce more centralization. The community has discussed longer-term options (consensus changes, merge-mining, ChainLocks-style protections), but no robust fix is implemented yet. Notably, Monero’s existing 10-block safeguard was insufficient against the 18-block reorg.
With Qubic’s sustained influence, Monero faces a crossroads: accept measures that may erode decentralization or risk repeated reorganizations that threaten network reliability.
