The upcoming Ethereum PeerDAS upgrade is set to unlock existing L2 bottlenecks, allowing nodes to verify data availability and thereby improve Ethereum’s scalability potential.
According to a statement on the X platform by Ethereum co-founder Vitalik Buterin, the Fusaka network upgrade, scheduled for activation on December 3, 2025, will occur after a series of public testnet trials in October.
Address Existing Data Availability Challenge
In his statement on Thursday, Buterin stated that the Ethereum PeerDAS Upgrade will address the existing data availability challenge by utilizing the core feature dubbed PeerDAS (Peer Data Availability Sampling). Buterin explained:
“PeerDAS is trying to do something pretty unprecedented: have a live blockchain that does not require any single node to download the full data […] the key to L2 scaling, and eventually L1 scaling.”
Rather than downloading complete blockchain data, the Ethereum PeerDAS upgrade will enable each node to download only a small chunk, using statistical sampling to ensure that complete data exists across the blockchain.

Improve Ethereum’s Scalability Potential
At its core, the Ethereum PeerDAS upgrade reimagines the way Ethereum nodes interact with blob data. The nodes will no longer have to individually store and verify the complete data set of every block.
Using erasure coding, the upgrade splits blobs into 64 data columns, which are subsequently extended to 128 columns. Explaining that the new technology will improve Ethereum’s scalability potential and that the developers have been “super cautious on testing,” Buterin added:
“This is also why the blob count will increase conservatively at first, and then become more aggressive over time.”
A Foundational Catalyst for L2 Growth
The nodes will be assigned a random subset of columns to store and verify. By using a sharding approach, this aims to ensure the network can collectively guarantee data availability while reducing individual node storage and bandwidth demands.
As a result, the Ethereum PeerDAS upgrade will facilitate an eight-fold increase in blob throughput, from 6 to 48 blobs per block, without compromising decentralization, security, or node accessibility.

The technical leap is intended to become a foundational catalyst for L2 growth, validator yield extension, and an increase in Ethereum’s scalability potential towards long-term dominance in the rollup-centric era. The statement further reads:
“Providing additional data availability helps bring scale to Ethereum users in the context of layer two systems called ‘rollups’ whose dominant bottleneck is layer 1 data availability.”
Other technical enhancements in the Ethereum PeerDAS upgrade will incorporate updates to gas pricing, such as those that tie blob fees to execution costs in a way that prevents market distortion. The changes are designed to mitigate denial-of-service risks and enhance Ethereum’s scalability potential, ensuring consistent performance as the network scales.
Conclusion
The Ethereum PeerDAS upgrade goes beyond being a mere technical upgrade. It aims to enhance Ethereum’s scalability potential and position the network as the backbone of the rollup era. By facilitating an eightfold increase in throughput, the upgrade could accelerate L2 growth, strengthen its validator economics, and ultimately enhance its dominance.

Frequently Asked Questions about Ethereum scalability
What are the scalability issues with Ethereum?
Ethereum’s main scalability issue is its limited transaction throughput, currently around 15-30 transactions per second.
Why is scalability a challenge in Ethereum’s operations?
Poor scalability becomes a significant limitation, leading to network congestion, higher gas fees, and slower transaction times.
Why is improving scalability on Ethereum essential?
Improving the scalability will reduce network congestion, leading to lower transaction fees and quicker confirmation times. Users no longer need to compete for block space, making the technology more accessible and user-friendly.
