Ethereum Co-founder: PeerDAS 'is trying to do something pretty unpredecented'

The Ethereum Foundation announced that Ethereum’s Dencun upgrade was activated on March 13, 2024. It introduced EIP-4844 "blob" transactions to lower Layer 2 (L2) costs and lay the groundwork for full danksharding. Blobs store data ephemerally in consensus clients, with commitments accessible to the Ethereum Virtual Machine (EVM). This separation makes rollup data cheaper while preserving verifiability. Dencun’s mainnet timing and purpose were formally announced by the foundation, establishing the baseline that Fusaka intends to scale further via PeerDAS.

PeerDAS relies on erasure coding and probabilistic sampling; if more than 50% of chunks are available, nodes can reconstruct the full dataset from the available parts. Research posts from core contributors outline distribution and sampling phases that collectively provide strong guarantees of availability under adversarial conditions.

Buterin is a Canadian programmer and writer best known as a co-founder of Ethereum. Active in crypto since 2011, he co-founded Bitcoin Magazine and helped launch Ethereum in 2015, shaping its roadmap toward scalability and security through proposals like rollups, proto-danksharding, and data availability sampling.

Ethereum is a decentralized platform for programmable smart contracts and applications secured by a global network of validators. The protocol supports tokens, decentralized finance (DeFi), non-fungible tokens (NFTs), and DA-layer services for rollups. Upgrades such as Dencun (EIP-4844 blobs) and planned steps like PeerDAS target massive throughput gains without sacrificing decentralization by keeping validation accessible.
