Vitalik Buterin, co-founder of Ethereum, has said that the Ethereum Foundation has enhanced its peer-to-peer networking expertise. He cited PeerDAS as evidence of improvements in speed, resilience, and privacy.
“For years, I’ve complained internally at the EF that we do not have enough expertise at p2p: we think a lot about cryptoeconomics, BFT consensus and blocks, but we take the p2p networking layer for granted,” said Buterin. “I think that’s no longer true, and PeerDAS shows it. Raulk and others at EF have done heroic work both at making PeerDAS work so smoothly, and at setting up a roadmap that increases propagation speed, resilience, and network-layer privacy at the same time. Excited to see this work keep moving forward.”
According to Buterin’s post on X, the Ethereum Foundation has historically focused on cryptoeconomics and consensus while underinvesting in the peer-to-peer layer. He said this is now changing. Buterin credited raulk and other contributors from the Ethereum Foundation for making PeerDAS “work so smoothly” and advancing a roadmap focused on faster propagation, greater resilience, and improved network-layer privacy. He framed recent market infrastructure work as practical engineering progress rather than narrative.
PeerDAS (Peer Data Availability Sampling) is described by Ethereum.org as a protocol roadmap component aimed at scaling Ethereum’s data availability for rollups by changing how blob data is handled and propagated. The documentation positions PeerDAS as a significant step in improving the capacity and efficiency of data distribution, emphasizing strengthening the underlying networking layer so the chain can support more data throughput without requiring every participant to download everything.
EIP-7594 specifies PeerDAS as a networking protocol that enables nodes to perform data availability sampling for blob data. It outlines how peers exchange and verify sampled data to ensure availability. The proposal details objectives and mechanics for sampling and distribution across the network, providing a technical basis for claims that PeerDAS can improve propagation behavior and robustness by moving availability checks and data movement into the peer-to-peer layer rather than relying on a small set of actors.
Buterin is widely known as a co-founder of Ethereum and remains a prominent technical voice on protocol research and scaling priorities. The Ethereum Foundation describes itself as a non-profit organization supporting the Ethereum ecosystem by funding protocol development, growing the ecosystem, and advocating for Ethereum while emphasizing it does not “control” the network—context for why Buterin frames EF work in terms of expertise, roadmaps, and contributor output.
