🚨 Monero Faces Possible 51% Attack — What You Need to Know 🚨

TL;DR: Qubic claims to have briefly controlled over 51% of Monero’s hashrate, sparking concerns over blockchain integrity, double-spending risks, and transaction censorship. While costly to sustain (~$75M/day), the incident has shaken market confidence.

🛠 What Happened

Qubic mining pool allegedly surpassed the 51% threshold on Monero’s network.

A 6-block chain reorganization (~60 orphaned blocks) was observed.

This level of control can, in theory:

Rewrite the blockchain 📝

Enable double-spending 💸

Censor transactions 🚫

📊 On-Chain & Community Reactions

Some Monero devs argue the reorg alone doesn’t prove a sustained attack—could be short-lived or “lucky.”

Market reaction: XMR dropped 6–16% in the past 24h–7d.

Mixed views: Alarm over network vulnerability vs. skepticism about Qubic’s motives (self-promotion & token pump).

💰 The Economics

Experts estimate controlling Monero’s hashrate costs ~$75M/day.

Economic gains from such a move remain unclear.

Short-term attacks may still cause market disruption and trust erosion.

🔍 Why It Matters

Monero’s RandomX mining was designed to resist ASIC domination & centralization.

This event highlights that even privacy-focused PoW chains aren’t immune to hashrate concentration.

Potential wake-up call for mining decentralization and network defense strategies.

📌 Takeaway

Whether this was a full-blown 51% attack, a stress test, or a PR stunt, the risk is real.
Exchanges, services, and the community must stay vigilant for suspicious activity.

🗨️ Question for you:
If a major privacy coin like Monero can be hit, are PoW blockchains still secure enough in 2025?
