PeerDAS and a 48 blob target in 2025

PeerDAS (EIP-7594) is presented as the step that lets Ethereum scale to at least a 48 blob target per block, an eightfold increase in blob capacity over the current 6-blob target. Under the approach, nodes no longer download all blob data; instead, each full node downloads and verifies a small, randomly assigned portion and relies on sampling, with each validating node custodying 8 data columns. The article says this raises throughput from about 220 to about 3,500 UOPS without adding node storage or bandwidth requirements, and it notes that the 768 kB per-block storage figure matches today's requirement. OP Labs says it is collaborating with Sunnyside Labs, Base, and Soneium ahead of the Fusaka upgrade, which it targets for later this year.
