PeerDAS boosts data throughput, cuts costs, and strengthens the foundation for faster, lighter user interactions across the Ethereum stack
Ethereum’s Fusaka upgrade is now live, marking a technical leap that expands data capacity, sharply reduces transaction expenses and moves the network closer to delivering an “instant-feel” user experience. Activated at Epoch 411392, the upgrade introduces Peer Data Availability Sampling (PeerDAS)—a mechanism that reshapes how Ethereum and Layer-2 networks handle data.
At the heart of Fusaka is PeerDAS, a system that splits large rollup data blobs into small, easily shareable cells, dramatically reducing the load on node operators. This allows information to circulate more efficiently while maintaining decentralization. According to analysts tracking the upgrade, this approach can provide up to 8x more data throughput for Layer-2s.
The Ethereum Foundation described the change as a critical step toward near-real-time confirmations, explaining that transaction latency may drop from minutes to milliseconds, paving the way for smoother, application-level interactions.
Industry watchers have also highlighted the economic implications. As one independent rollup engineer put it, “PeerDAS doesn’t just improve bandwidth—it directly translates into cheaper blob fees and greater headroom for rollup growth.”
Fusaka’s efficiency gains have fueled optimism among traders. Several market commentators argue that Ethereum’s fundamentals are strengthening faster than its price reflects.
With lower fees, greater capacity, and a markedly faster UX, Fusaka positions Ethereum for the next wave of high-volume, consumer-grade applications.
