Ethereum Fusaka Upgrade with PeerDAS on Dec 3
Ethereum developers have set the Fusaka Ethereum upgrade for Dec 3, 2025, at 21:49 UTC (slot 13,164,544) as the network’s second hard fork of the year. Announced at the All Core Developers Consensus Layer call #168, this Ethereum upgrade features PeerDAS—one of 12 improvements enabling validators to verify data subsets instead of full blobs. By reducing bandwidth demands, PeerDAS cuts validation costs and accelerates transactions across validators, layer-2 networks and users. The Fusaka upgrade completed a smooth rollout on the Hoodi testnet, aiming to enhance network performance, lower transaction fees and boost scalability for developers and traders.
Bullish
The Fusaka upgrade introduces PeerDAS and other optimizations that lower validation costs, reduce gas fees and improve network throughput. By enhancing scalability and efficiency, the update should attract more users and layer-2 activity, increasing demand for ETH. Historically, performance-focused upgrades boost market confidence and long-term adoption. While short-term volatility may occur around the fork date, the fundamental improvements are likely to support a bullish outlook for Ethereum’s price in both the short and long term.
