Key Takeaways
- Ethereum price has surged 9% as anticipation builds for the Fusaka network upgrade.
- Fusaka introduces key scaling and security improvements, including PeerDAS, blob scaling, and several EIPs targeting data efficiency and gas cost management.
Ethereum has climbed 9% over the past 24 hours as the network approaches its next milestone, the Fusaka upgrade.
According to CoinGecko data, ETH is changing hands near $3,100 and has logged more than $30.7 billion in trading volume. The upswing has also been supported by a crypto market turnaround led by Bitcoin.
Slated to go live on the Ethereum mainnet at slot 13,164,544 (December 3, 2025, 21:49:11 UTC), Fusaka, Ethereum’s next major upgrade after Pectra, will merge the Osaka execution-layer changes with the Fulu consensus-layer. The upgrade is built to make the network faster, more efficient, and easier to use across the ecosystem.
Fusaka will introduce several changes that developers and analysts believe could strengthen Ethereum’s scalability path and make the network more adaptable to future growth.
The upgrade’s core feature, PeerDAS, aims to optimize data handling for layer 2 networks by considerably reducing the requirement for node storage, potentially increasing scalability eightfold.
Fusaka also features a more adaptable system for increasing blob capacity between major upgrades and updates Ethereum’s blob fee formula to keep data costs steady during congestion.
While Fusaka does not promise lower base fees, it is widely expected to improve the conditions for rollup growth, lighten the load on node operators, and prepare Ethereum for more responsive scaling in the years ahead.
The upgrade has already been tested on major public testnets, including Holesky and Sepolia. As with previous Ethereum upgrades, it activates automatically, with no action needed from everyday users.
After Fusaka activates, Ethereum will roll out two small Blob Parameter Only (BPO) upgrades that gradually raise blob capacity. The first will take place on December 9 and the second on January 7.
