Monero Defies Security Breach with 5.3% Rally Despite Historic 18-Block Reorganization
Privacy coin XMR surges above $302 as network faces largest blockchain reorganization in its history, raising critical security questions
Quick overview
- On September 14, 2025, Monero experienced its largest blockchain reorganization, resulting in the loss of 118 transactions over an 18-block reorg.
- Qubic, which controls over 35% of Monero's mining power, was blamed for the disruption, raising concerns about network centralization and security.
- Despite the network issues, Monero's price remained stable at around $302, indicating strong demand and investor confidence in a long-term solution.
- The community is exploring solutions like DNS checkpointing to enhance security, but this raises concerns about centralization conflicting with Monero's decentralized principles.
On September 14, 2025, Monero XMR/USD saw its biggest blockchain reorganization event. The network went through an 18-block reorg that effectively wiped 118 completed transactions. This unexpected disruption is the biggest change in Monero’s operating history. It happened at block 3499659 and lasted about 43 minutes before the network reached consensus again.
Qubic, an AI-focused blockchain project that has had a lot of say over Monero’s mining infrastructure, was blamed for the rearrangement. Qubic presently controls 2.11 GH/s of Monero’s total 6.00 GH/s network hashrate, which is more over 35% of the mining power. This means that the network is still at risk of becoming too centralized, which could threaten its basic security principles.
XMR/USD Technical Analysis Points to Resilient Price Action
Monero’s price has been very stable even though the network has been down for a long time. It is currently trading at about $302, up more than 5.3% in the last 24 hours. This price change that doesn’t make sense points to a number of important market forces at work.
From a technical point of view, XMR’s ability to keep going up during a security crisis shows that there is substantial demand and investors believe that a long-term solution is possible. The privacy coin’s performance is very different from what most people think about the market as a whole, as most cryptocurrencies had small drops within the same time period.
As Monero developer Sech1 pointed out, the 43% orphan rate seen in recent blocks implies that Qubic’s mining technique may not be cost-effective, even though it has the most power on the network. This inefficiency could put natural pressure on the market to make the attack less effective over time.
Security Implications Trigger Community Response
After the reorganization, blockchain security experts are quite worried about Monero’s risk of double-spending attacks. Yu Xian, the founder of the SlowMist security firm, called the persistent danger a “Sword of Damocles” hovering over the network. He stressed that the potential to carry out such assaults might damage long-term investor trust even if they are never actually used.
The event has made it necessary to make rapid modifications to how transactions are handled. Researchers in the field of security now say that XMR transactions should not be considered final until they have received a lot more than the usual 10 confirmations. Some even argue that confirmation periods should be longer until the network is stable again.
The Monero development community is now testing DNS checkpointing alternatives, although this method raises issues about centralization that go against the project’s decentralized philosophy. The community has a hard time finding the right balance between short-term security needs and long-term decentralization goals.
Monero (XMR) Price Prediction and Market Outlook
Even if there are security worries, Monero’s short-term price trend looks cautiously positive based on current technical indicators and market fundamentals. The fact that the token was able to rally amid a major network incident shows that it has substantial backing from both institutions and regular people, which may not be easily shaken by technical problems.
But for prices to keep going up, the community will probably need to be able to stop further restructuring attacks. If DNS checkpointing or another solution works in the next few weeks, XMR might test resistance levels between $320 and $330. This would be a 6–9% increase from where it is now.
On the other hand, if security worries stay the same or get worse, the privacy coin may have to deal with downward pressure toward support levels around $280–285. The most important thing will be whether the Monero development team can come up with good solutions before trust starts to drop quickly.
