Ethereum co-founder Vitalik Buterin framed the network\u2019s next scaling step as both audacious and tightly risk-controlled, saying \u201cFusaka will fix this\u201d while underscoring that \u201csafety first is of the utmost importance.\u201d In a detailed post, Buterin described Fusaka\u2019s core feature\u2014PeerDAS\u2014as \u201ctrying to do something pretty unprecedented: have a live blockchain that does not require any single node to download the full data.\u201d<\/p>\n

He added that PeerDAS relies on probabilistic sampling of data \u201cchunks,\u201d and, if more than half of those chunks are available, nodes can retrieve them and reconstruct the remainder via erasure coding. \u201cThis is all new technology, and the core devs are wise to be super cautious on testing,\u201d Buterin wrote, noting that blob supply will ramp \u201cconservatively at first,\u201d then more aggressively if conditions permit.<\/p>\n

Buterin Calls Fusaka the Key To Ethereum L2 Scaling<\/h2>\n

Buterin\u2019s remarks<\/a> arrive just as Ethereum\u2019s new blob market shows signs of strain. Head of Data at Dragonfly Hildebert Mouli\u00e9 reported that the chain \u201chit 6 blobs\/block for the first time,\u201d attributing the recent surge primarily to rollups and projects including Base<\/a> and Worldcoin. According to the same thread, Base submitted roughly 35% of blobs and used about 42% of blobspace, with Worldcoin<\/a> contributing around 20% of submissions and 25% of usage; Arbitrum, OP Mainnet, Soneium, Scroll and others comprised most of the remainder.<\/p>\n

The analyst added that L2s now account for about $200,000 per week in mainnet fees for submissions, validators require more than 70 GB of storage for blobs (over 1.2 TB if unpruned), and that many blobs are not fully utilized\u2014particularly on smaller rollups posting more frequently than they can fill 128 KB payloads. The first sustained base-fee spike since the Pectra hard fork was also observed, although hildobby cautioned that \u201cblob price discovery\u201d still requires a more prolonged saturation of demand.<\/p>\n

PeerDAS is the architectural response. Buterin explained that each node requests only a small number of chunks to verify that over half of the data is available; if so, the node \u201ctheoretically can download those chunks, and use erasure coding to recover the rest.\u201d<\/p>\n

In its initial incarnation, two non-custodial roles still require full-block data to exist somewhere on the network\u2014initial broadcast and emergency reconstruction when a publisher reveals only a fraction of a block\u2014though \u201cwe only need one honest actor\u201d for those tasks, and future \u201ccell-level messaging and distributed block building will allow even these two functions to be distributed.\u201d The endgame, he suggested, is to unlock sustained L2 scaling and, as L1 block gas limits rise, to eventually route more L1 execution data into blobs as well.<\/p>\n

This pivot lands amid a rapidly evolving blob marketplace. After Pectra<\/a>, Ethereum increased the blob target and maximum per block, expanding daily data capacity and paving the way for higher throughput from rollups; research desks have linked that shift to a complex interaction between L1 base fees, blob fees, and L2 submission behavior.<\/p>\n

The Fusaka timetable adds urgency. Core developers have signaled a mainnet activation for December 3, 2025, following staged testnet rollouts, placing Buterin\u2019s \u201csafety first\u201d emphasis in clear relief. PeerDAS will debut under strict limits, with blob counts increased \u201cconservatively at first,\u201d a posture designed to avoid fee whiplash and to observe how diverse L2s actually consume the added capacity.<\/p>\n

Outside the protocol notes, empirical work is accumulating around how networks might use blobspace more efficiently. A 2024 study on \u201cblob sharing\u201d argued that smaller rollups frequently under-fill blobs and could cut posting costs by more than 85% by cooperatively packing data into shared blobs, smoothing the base fee and lowering the total number of blobs submitted.<\/p>\n

Ethereum researchers have since expanded that argument, modeling how sharing reduces blocks with more than the target number of blobs and thereby dampens the exponential blob-fee adjustments that kick in when usage overshoots targets. Those findings dovetail with Mouli\u00e9\u2019s observation that \u201cmany blobs aren\u2019t full,\u201d implying large savings are available through better coordination as the market matures.<\/p>\n

The conceptual roots of PeerDAS stretch back through Ethereum research notes on data-availability sampling and Buterin\u2019s own writings on \u201cThe Surge.\u201d PeerDAS itself implements one-dimensional sampling with erasure coding and succinct per-cell proofs, enabling nodes to validate availability without naively downloading everything. That\u2019s what makes the approach \u201cpretty unprecedented\u201d in a live, high-value blockchain: it seeks to reconcile decentralization and throughput by reducing per-node bandwidth and storage requirements while preserving strong guarantees that data actually exists.<\/p>\n

Still, the shift is not without risks. Buterin\u2019s insistence on a careful rollout reflects the reality that Ethereum\u2019s blob economy is young, volatile, and sensitive to sudden changes in demand. As L2s jostle for capacity, fee dynamics can invert quickly, and incomplete blobs, spiky usage, and MEV side effects complicate forecasting. The promise of Fusaka is that PeerDAS can bend those dynamics toward sustainable growth by letting the network scale data availability without forcing any single node to shoulder the whole chain\u2014and by doing so in a way that keeps security assumptions explicit and testable.<\/p>\n

At press time, ETH traded at $4,028.<\/p>\n
