Ethereum Devs Raise Blob Limit From 15 to 21

Ethereum achieved a scalability boost with the second Blob Parameter-Only (BPO) hard fork, which took effect on Wednesday, raising the blob limit from 15 to 21. This change increases the network's data throughput, allowing more transactions to be batched via rollups. The BPO hard fork also increased the blob target from 10 to 14, although this metric is watched closely as consistently hitting the 21-blob limit could strain node resources. With one blob holding 128 kilobytes, Ethereum can now store up to 2,688 KB per block. Blobs also contribute to stabilizing mainnet gas fees by reducing congestion. Furthermore, developers are considering raising the network gas limit from 60 million to 80 million, and the upcoming Glamsterdam hard fork in 2026 aims to further increase the gas limit to 200 million and introduce "perfect parallel processing" via Block Access Lists (EIP-7928) to transform transaction processing.
