Fusaka rollout kicks off Ethereum’s new twice-a-year hard-fork schedule

Ethereum's 17th major upgrade, Fusaka, went live, marking the start of the Ethereum Foundation's accelerated twice-a-year hard-fork cadence, moving away from the previous annual schedule.

The upgrade's headline feature is PeerDAS (Peer Data Availability Sampling), introduced via EIP-7594, which allows validators to sample data segments instead of downloading entire blobs, benefiting Layer 2 rollups by increasing throughput without proportionally raising bandwidth needs for individual nodes. This is supported by "Blob Parameter Only" updates planned to significantly increase per-block blob capacity.

Fusaka also includes pricing fixes like a blob base fee minimum to stabilize costs, and protocol improvements such as boosting the gas limit cap and adding native support for the secp256r1 elliptic curve for passkey support. While focusing on "backend boosts" for scaling, it sets the stage for future upgrades like Glamsterdam, expected in 2026.
