Rollups Push for Higher Blob Capacity in Fusaka Upgrade
Major layer-2 teams are lobbying for a further increase in blob throughput to reduce fees for end users.
Major layer-2 development teams have used recent Ethereum research calls to push for a further increase in blob throughput in the upcoming Fusaka hard fork. The argument, made publicly by contributors from Arbitrum, Optimism, Base and Scroll, is that current blob capacity is now the binding constraint on layer-2 fee reductions.
Client teams have responded cautiously, pointing to the need for PeerDAS-style data availability sampling before capacity can be scaled aggressively without imposing unrealistic bandwidth requirements on full nodes.
The debate is expected to shape which EIPs make the final Fusaka scope, with several intermediate options currently on the table.
