Ethereum Blob capacity expanded to 21 through new hard fork – what changes?

2026-01-13 09:49:08

The Ethereum network has conducted its second BPO-driven hard fork, implementing a significant infrastructure upgrade. The key element of this upgrade: the blob limit has been increased to 21, providing rollup solutions with a substantial performance boost.

Why this increase in blob capacity is important

Blobs are specialized data blocks designed specifically for Layer-2 rollups. By raising the limit to 21, more transactions can be processed simultaneously. This directly reduces the fee structure – a development that brings notable savings for users.

Focus on scalability: practical impacts

With this hard fork, the overall performance of the Ethereum blockchain is significantly enhanced. The increased capacity allows protocols to handle higher transaction volumes more cost-effectively. This helps decentralized applications and developers to utilize blockchain technology more economically.

The upgrade positions Ethereum as a more attractive platform for those seeking scalable and cost-efficient on-chain solutions. The combination of increased capacity and reduced transaction fees strengthens Ethereum’s competitiveness in the ecosystem.
