Ethereum's rollup-centric roadmap requires that data is made available on L1. Introduced via EIP-4844 as a cost-effective alternative to calldata, blobs are data objects used by many rollups today to publish their transaction data or state diffs to L1. As the demand for blobs increases, forks such as Pectra are set to boost blobspace supply, thus preventing blob gas fees from becoming impracticable.

In tandem with such steps along the Danksharding roadmap, we recognize that blobspace is not always efficiently utilized, with bytes being lost to zero padding or because of uncoordinated commit schedules between rollups. Emerging proposals advocate for more efficient blobspace utilization via mechanisms such as blob sharing or dynamic blob sizes. In this work, we survey such proposals, seeking to understand their feasibility and suitability for different rollup designs, such as zkSharding -- a sharded validity rollup architecture. We aim to consolidate a research direction complementing the Danksharding roadmap, whereby blobs are most efficiently used, maximizing the economic benefits of EIP-4844.
