On January 7, Ethereum developers implemented the Blob Parameter-Only (BPO) fork on the mainnet, raising the limit of BLOB objects from 15 to 21.

The update also increased the target BLOB value from 10 to 14.
Each BLOB object can hold 128 KB of data, allowing Ethereum blocks to now store up to 2688 KB (at maximum capacity). This enhancement enables the processing of more transactions simultaneously, improving blockchain efficiency without directly risking overload.
This fork marks the second increase in BLOB limits since the activation of the Fusaka upgrade. The previous BPO was implemented on December 9, 2025.
The Ethereum team's initiative aims to enhance the throughput of rollups. In addition to scaling second-layer solutions, BLOB objects have also helped keep base layer fees in check.
Since the end of last year, gas prices on the mainnet have shown greater stability.

Almost simultaneously with the update, on January 6, the withdrawal queue from Ethereum staking reached zero. By the time of writing, the figure has slightly recovered, with the current waiting time for unlocking coins being about an hour.

Recall that on December 30, the second-largest cryptocurrency network set a new record: 2.2 million processed transactions in a single day.
