On September 14, 2025, Monero underwent an 18-block reorganization, raising concerns about double spending and affecting user and exchange trust.
What Happened to Monero
The Monero block reorganization occurred on September 14, 2025, resulting in the erasure of 118 transactions. This incident was linked to rising mining centralization associated with Qubic's operations, led by Sergey Ivancheglo. Concerns about double spending vulnerabilities have arisen as Qubic commands a significant share of the network's hashrate.
Impact on Markets and Exchanges
The block reorganization had wide-reaching effects on the cryptocurrency market and user trust. The exchange Kraken suspended XMR deposits and increased transaction confirmation levels. "We have suspended Monero deposits and increased the required confirmations from 10 to 720," stated Kraken representatives.
Possible Consequences and Analysis
Monero's financial metrics reflect declining market confidence. The reorganization accelerated XMR price drops, aligning with historical data on market disruptions linked to similar security issues. Analysts point to technical flaws and high orphan rates as key contributors to the incident. The centralization may lead to increased regulatory scrutiny, which could impact future protocol changes.
Monero's block reorganization represents a significant event, raising security concerns in the cryptocurrency space. Experts stress the need for further analysis and possible regulatory oversight regarding centralized operations.
