Ethereum completed its most aggressive capacity expansion of 2025 on Wednesday, activating the Fusaka hard fork to immediate market applause. The upgrade, a fusion of the Fulu consensus and Osaka execution layers, fundamentally alters the network’s scarcity model by increasing data throughput eightfold without sacrificing decentralization.
Fusaka brings two major improvements. First, PeerDAS increases Ethereum’s data throughput up to eight times, giving rollups significantly more blockspace to operate. More rollups mean more users, more applications and higher revenue for the ecosystem.
Second, new UX features like the R1 curve and pre-confirmations make Ethereum easier and faster to use. Developers say these upgrades enable secure mobile authentication and smoother wallet interactions, reducing friction for onboarding new users.
it as “the strongest builder momentum since the Merge in 2022,” adding that the upgrade proves Ethereum is “no longer an experiment, but an inevitability.”
Ethereum’s Fusaka upgrade could impact ETH’s price in a way similar to past upgrades. In March 2024, the Dencun upgrade launched and delivered big improvements for rollups through proto-danksharding. ETH rallied 84% in the six weeks leading into the upgrade but then fell 25% in the following week.
Then came Pectra in May 2025. ETH had already crashed more than 60% from December 2024 to April 2025, and the upgrade arrived just after ETH hit its bottom. ETH bounced 23% before Pectra and then exploded 50% in the week after it went live.
Ethereum has been one of the top gainers in the last 24 hours. ETH is trading around $3,205, up more than 5%, while Bitcoin remains comparatively flat near $93,401.
The token is trying to break above the important $3,200 level. If that happens, the next levels to watch are $3,250–$3,300, and then a stronger resistance zone near $3,600–$3,700. double-bottom pattern, which points to a possible move toward $3,430.
But ETH is getting close to being overbought again, so the price could cool down for a bit soon. If ETH holds above $3,100, it still has room to move toward $3,300–$3,430.
