Ethereum’s revolutionary Fusaka upgrade has unlocked a significant scalability boost, exceeding the $4,000 mark in a surge driven by Layer 2 network performance and institutional investments. The upgrade, which activated on December 3, 2025, is built around PeerDAS (Peer Data Availability Sampling) technology, increasing blob capacity eightfold and reducing validator load by 85%. This has led to impressive transaction speeds on Ethereum’s Layer 2 networks, surpassing Visa in TPS and powering new DeFi, gaming, and dApp experiences with lower fees. This impactful upgrade follows the May’s Pectra rollout, demonstrating Ethereum’s commitment to continuous improvement and biannual hard forks, accelerating from post-Merge era’s deliberate pace. The surge in ETH price reflects this positive sentiment as institutions continue accumulating ahead of long-term goals like $3,500-$4,000.
