Ethereum Price Rises as Post-Quantum Security Upgrades Gain 20%

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

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

Quantum is coming. The industry is just now catching up.

Naoris doesn’t need to pivot.
We were built for this exact problem.

Welcome to a quantum-proof future.

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

While overall progress is estimated at around 20%, Sanso highlighted that the FE 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 an important differentiator, especially compared to Bitcoin, where executives have been slower to act on quantum-proof upgrades.

Ethereum price signals bullish reversal near $2,850 support

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

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

The main resistance lies in the $3,250-$3,300 area, which has historically capped gains. Traders will likely watch for a break above this area as it would indicate further bullish strength and could open the door for further gains towards $3,400. On the downside, failure to hold the $2,850 support could prompt short-term sellers to push prices lower, with the next support near $2,750.

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

Currently, Ethereum is positioned in a critical zone where the direction of the market over the next few sessions will determine whether the bullish reversal continues. Traders and investors are likely to closely monitor price action, especially around the $2,900-$3,000 pivot zone, for possible entry opportunities.

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