Vitalik Buterin: Ethereum’s PeerDAS will be key to L2 scaling
The post Vitalik Buterin: Ethereum’s PeerDAS will be key to L2 scaling appeared on BitcoinEthereumNews.com. Ethereum co-founder Vitalik Buterin believes Peer Data Availability Sampling (PeerDAS), a core feature of the upcoming Fusaka upgrade, will fix Layer-2 scalability issues for the Ethereum blockchain. Speaking Thursday in response to an X thread by Dragon XYZ’s head of data, Hildebert Moulié, Buterin explained that the technology will help nodes verify data without requiring them to download the entire blockchain. “The way PeerDAS works is that each node only asks for a small number of chunks, as a way of probabilistically verifying that more than 50% of chunks are available,” Buterin wrote on X. “If more than 50% of chunks are available, then the node theoretically can download those chunks, and use erasure coding to recover the rest.” The programmer reiterated that this would allow a live blockchain on Ether to operate without any single node having to store full datasets. Ethereum network reaches blobs per block record Late Wednesday, Moulié noted that Ethereum had reached its target of six blobs per block for the first time in history. Blobs, or Binary Large Objects, were introduced to Ethereum through the Dencun upgrade in March 2024 under EIP-4844, also known as proto-danksharding. According to Moulié, blob usage during the spike was largely driven by activity across several L2 rollups. Base accounted for 42% of blob activity, followed by World with 25%, while other contributors included Arbitrum at 8%, OP Mainnet at 4%, and Soneium and Scroll at 3% each. 5/ current used blobspace % 42% Base25% World8% Arbitrum4% OP Mainnet3% Soneium3% Scroll2% Unichain2% Shape2% Lighter1% Ink pic.twitter.com/J6EWWp0VF7 — hildobby (@hildobby) September 24, 2025 Blobs were developed to reduce transaction costs for Layer-2 networks by providing dedicated storage for compressed data.
