She focuses on questions pertaining to data availability and works on the design of the synchronization layer that enable shards to share the operational burdens of DA and proving. Previously, she worked as a privacy and decentralized systems researcher across a variety of projects, primarily within academia. Raluca is convinced of the impact potential decentralized technologies can have in shaping a better Internet and economies.

EIP-4844 introduced cheaper, although temporary storage on Ethereum, allowing rollups to publish data cost-efficiently. With new and old rollups alike opting for such storage, blob count limits are set to increase with future network upgrades in the hope they meet demand. Another emerging approach to supplement blobspace consists of efforts for more efficient utilization, in essence by preventing (in aggregate) wasting valuable bytes to zero padding. In this talk, we explore proposed mechanisms, highlighting their suitability for different types of rollup architectures, as well as the challenges posed to research and development teams on both layers. Our goal is to consolidate a research direction towards more efficient utilization of blobspace, complementing the Danksharding roadmap.
