Ethereum’s (ETH) Fusaka Upgrade Set to Boost Rollup Scaling 8× With PeerDAS

• Fusaka introduces PeerDAS, enabling up to 8× more blob throughput for rollups.
• Recent data shows blob usage rising toward the new target of 6 ahead of the upgrade.
• Upgrade enhances scalability, lowers rollup fees, and improves network efficiency.

Ethereum is getting ready to introduce its second update for the year – Fusaka-, which will be released within Q4 2025. Fusaka will encompass improvements to the execution layer and consensus layer to give Ethereum improved scalability, security, and overall user experience. The big feature of this upgrade is called PeerDAS. PeerDAS is a new type of data availability mechanism that allows for significantly greater capacity for rollups.

The Official Announcement

According to the recent update on X by the Ethereum official account about Fusaka as the next step in evolution for the ETH network, and talked about the features of PeerDAS and the expected effects that it will have regarding costs and throughput.

“Ethereum’s second major upgrade this year → PeerDAS unlocks up to 8× data throughput, enabling cheaper blob fees and more space for rollups to grow.”

Blob Usage Data Growth Prior to Fusaka

The Dune Analytics graph indicates (As of December 2025) that the expected number of blobs should be six with a current average number of approximately five and two tenths that mirrors the increased demand placed on Layer 2 rollups, showing that there is a growing need for Fusaka to address scalability by implementing PeerDAS so that it can give ETH greater throughput at a reasonable cost to storage.

By distributing blob data to all node participant nodes using PeerDAS, it allows for creating a more efficient distributed ledger and keeps the amount of hardware required to process transactions within reasonable limits.

In conclusion, Fusaka represents a major step up in the ETH’s scaling roadmap. With PeerDAS, the increasing demand for blobs in the ETH ecosystem can be handled without affecting the decentralisation aspects of the coin.

By continuing to introduce gradual increases in blob parameters along with cost protection mechanisms, ETH is preparing itself for a more successful rollup ecosystem, as well as a reduction in the amount of fees users will pay to access Ethereum in 2025 and beyond.
