Ethereum Surges 3% as Post-Quantum Security Upgrades Gain Momentum

Ethereum’s price surged 3% in the last 24 hours, climbing to $2,963, after investors responded positively to news that Ethereum is on track to become quantum-resistant, ensuring its blockchain remains secure even if powerful quantum computers appear in the future.

Antonio Sanso, a cryptography researcher at the Ethereum Foundation (EF), confirmed that the foundation has moved from research into the execution phase of post-quantum (PQ) upgrades and is confident it will meet its planned timeline.

Post-quantum security is now a top priority for Ethereum. The EF recently formed a dedicated Post-Quantum team led by Thomas Coratger and will hold biweekly All Core Devs calls starting Feb. 4, 2026, to discuss progress and implementation strategies. These upgrades will touch Ethereum’s execution, consensus, and data availability layers, making the network more resilient against future quantum attacks.

While overall progress is estimated at around 20%, Sanso emphasized that the EF has been preparing for this transition for years, with a clear roadmap guiding development. This work is part of the broader “Lean Ethereum” initiative, which aims to make the network faster, simpler, and more decentralized while integrating zero-knowledge (ZK) technology alongside quantum-resistant solutions.

Investors see this proactive approach as a strong differentiator, particularly when compared to Bitcoin, where leaders have been slower to act on quantum-proof upgrades.

Ethereum Price Signals Bullish Reversal Near $2,850 Support

Ethereum price shows signs of recovery after recent consolidation near a major support level around $2,850. The 4-hour chart indicates that ETH is attempting to stabilize after a pullback from the $3,250 resistance zone. Technical indicators show a possible bounce toward the reward zone with an initial target price near $3,300, as bulls aim to reclaim previous highs.

The chart highlights a rounded bottom pattern, a classic bullish reversal formation, signaling that the downtrend may have ended and momentum is shifting in favor of buyers. This pattern is supported by multiple touches at the major support level, confirming a strong buying interest at these prices. If the pattern plays out, ETH could see a sustained move upward toward the upper resistance zone.

Key resistance lies in the $3,250–$3,300 area, which has historically capped gains. Traders are likely to watch for a breakout above this zone, as it would indicate renewed bullish strength and could open the door for further gains toward $3,400. On the downside, failure to hold the $2,850 support may prompt short-term sellers to push prices lower, with the next support seen near $2,750.

The Relative Strength Index (RSI) on the 4-hour chart is near 50, showing neutral momentum but trending slightly upward, suggesting that buyers are gradually regaining control. A move above 60 on the RSI could confirm bullish momentum, while a drop below 40 may signal renewed selling pressure.

Right now, Ethereum is positioned in a critical zone where market direction over the next few sessions will determine if the bullish reversal continues. Traders and investors are likely to monitor price action closely, especially around the $2,900–$3,000 pivot area, for potential entry opportunities.

If ETH maintains support and momentum, a climb toward the $3,300–$3,400 target range appears plausible, offering a favorable risk-to-reward setup for short-term traders. ETH’s technical outlook aligns with positive market sentiment around Ethereum’s ongoing network upgrades and long-term security initiatives, which continue to bolster investor confidence.
