Buterin: PeerDAS in Fusaka will improve Ethereum's L2 and L1 scaling

Ethereum reached a significant milestone: the first block with six blobs was processed, announced Gildebert Moulier, Head of Data at Dragonfly. According to him, a significant portion of the activity came from projects such as Base and Worldcoin, as well as Scroll, Soneium, Shape, Lighter, Linea, and others.
Blobs, introduced as part of EIP-4844, are large data packets temporarily stored on the Ethereum blockchain. They were designed to reduce network congestion and improve the efficiency of L2 solutions. Currently, Base and Worldcoin account for the majority of this volume: the former generates approximately 35% of all blobs, the latter 20%. The remaining projects each generate less than 10%.
However, the growing number of blobs also poses technical challenges. Moulier noted that validators already require over 70 GB of storage space to store information, and without deleting old data, the volume exceeds 1.2 TB. Furthermore, approximately 10% of blobs contain very little data—less than 128 KB.
According to him, L2 blockchains generate approximately $200,000 in weekly fees for the main network. Increased costs for submitting blobs should also be taken into account, as network load gradually recovers.
Amid these discussions, Ethereum co-founder Vitalik Buterin drew attention to the upcoming Fusaka upgrade. Its central feature will be the PeerDAS feature, which will allow data verification without downloading the entire block. The key goal is to confirm the presence of more than half the information while maintaining the security and efficiency of the network.
Buterin emphasized that the introduction of more blobs will be gradual to minimize risks. He also noted that blobs could become an important scaling tool not only for Layer 2 solutions but also for the Ethereum mainnet, especially when L1 gas limits reach critical levels.
As a reminder, the Fusaka hard fork on the Ethereum mainnet is scheduled for December 3, 2025. This update is expected to play a key role in the further development of the blockchain infrastructure and expanding capabilities for decentralized applications.
