Ethereum may have a simpler way to ease the computing burden of its growing rollup ecosystem

An Ethereum prototype that divides blob-recovery duties among nodes reported an 11–18× reduction in estimated reconstruction computing work across 1,000-node simulations. The results suggest operators could reduce duplicated work through a smaller change than the full RowDAS networking proposal.

Researcher Csaba Kiraly's Sept. 3 report describes the reduced design as a possible first step toward RowDAS. It assigns recovery duties without introducing the new row-networking channels in the full proposal.

Blobs carry data used by layer-2 rollups. PeerDAS, Ethereum's system for checking that blob data is available, lets nodes download only part of it. High-custody nodes hold at least 64 of the 128 data columns, enough to rebuild missing blob data; supernodes hold all 128.

Many high-custody nodes can repeat the same reconstruction. The reduced design assigns particular blobs to them first, allowing others to receive the recovered data instead of immediately rebuilding it themselves.
