A second Blob Parameter-Only hard fork increased Ethereum's blob limit from 15 to 21 and the blob target from 10 to 14, enabling up to 2,688 KB (21 × 128 KB) of blob data per block. The change took effect at 01:01:11 UTC and is intended to increase data throughput for rollups, lower layer-2 costs and help stabilize mainnet gas fees. Developers are also discussing raising the network gas limit from 60M to 80M, with a planned 2026 Glamsterdam hard fork to target up to 200M gas and introduce “perfect parallel processing” via EIP-7928.

The hard fork concretely raised the blob limit from 15 to 21 and blob target from 10 to 14, increasing per-block data capacity to 2,688 KB and explicitly aiming to lower layer-2 costs and stabilize gas; developers are discussing further gas-limit increases and a 2026 hard fork (Glamsterdam) to raise gas to 200M and add parallel processing (EIP-7928).
