Ethereum is exhibiting indicators of pressure when dealing with data-heavy blocks weeks after its December Fusaka improve, elevating issues about whether or not the community is able to help increased knowledge throughput from layer 2 blockchains, in accordance with new analysis from MigaLabs.
Key Takeaways:
- Ethereum is failing to reliably course of data-heavy blocks regardless of increased blob limits launched by the Fusaka improve.
- Blocks with 16 or extra blobs present sharply increased miss charges in contrast with regular community circumstances.
- If layer 2 demand rises, these elevated miss charges might threaten Ethereum’s community stability.
The Fusaka laborious fork was designed to develop Ethereum’s knowledge capability by permitting layer 2 networks to submit extra “blobs,” a type of short-term knowledge used primarily by rollups to submit transaction info to the principle chain.
The change was extensively seen as a step towards cheaper and extra scalable layer 2 exercise.
Ethereum Blocks With Larger Blob Counts Face Larger Miss Charges
Nevertheless, an empirical evaluation printed by MigaLabs means that blocks carrying increased blob counts are considerably extra more likely to be missed by the community.
The analysis attracts on knowledge collected since October 2025 and examines community habits earlier than and after Fusaka, in addition to two subsequent Blob-Parameter-Solely (BPO) updates that raised blob limits additional.
MigaLabs, which has beforehand collaborated with Lido DAO and the Cambridge Centre for Different Finance, discovered that Ethereum just isn’t coming near utilizing the expanded capability.
Regardless of will increase to the goal blob rely, most lately raised to 14, the median variety of blobs per slot has really fallen for the reason that first BPO replace.
Excessive blob counts of 16 or extra stay uncommon, showing just a few hundred instances out of greater than 750,000 noticed slots.
Extra troubling is what occurs when blob counts do spike. The research reveals that missed-slot charges rise sharply as soon as blocks comprise 16 or extra blobs.
Tomorrow: Fusaka
Ethereum’s second main improve this 12 months.
→ Characteristic spotlight: PeerDAS – Unlocking as much as 8x knowledge throughput. For rollups, this implies cheaper blob charges and extra space to develop.

Whereas the baseline miss price for slots with as much as 15 blobs hovers round 0.5%, miss charges at increased blob counts vary from 0.77% to as excessive as 1.79.
On the most noticed stage of 21 blobs, the miss price was greater than 3 times the community common.
These blobs are primarily submitted by giant layer 2 networks reminiscent of Arbitrum and Base, which depend on Ethereum’s knowledge availability to function securely.
If demand from these networks will increase and excessive blob counts change into extra frequent, the elevated miss charges might compound and pose dangers to total community stability.
MigaLabs Urges Pause on Ethereum Blob Will increase Amid Rising Miss Charges
MigaLabs cautioned that whereas the pattern measurement for very excessive blob counts remains to be restricted, the sample is constant throughout all noticed knowledge factors.
In its conclusion, the agency really useful towards any additional will increase to blob capability till miss charges at increased blob ranges return to baseline and actual demand begins to strategy present limits.
As reported, the Ethereum Basis has elevated post-quantum safety to a core strategic focus, forming a devoted Submit Quantum crew and committing $2 million to the hassle.
Introduced by Ethereum researcher Justin Drake, the initiative will probably be led by Thomas Coratger alongside Emile, a contributor to leanVM.
