Asked: What are blobs, and why do they lower L2 fees?
I usually answer like this: The Fusaka upgrade in December 2025 brought PeerDAS. Nodes only need to sample a portion of the blob data, and the blob limit was later increased as well. Blobs are cheap because blob data is only stored for about 18 days, doesn’t need to be kept permanently, and isn’t used in EVM computation, which puts a much smaller burden on nodes.
