Definition
Danksharding is an Ethereum protocol design for a unified, rollup-centric data-availability layer in which a single proposer selects all block contents, including large data blobs, and specialized samplers verify data availability. It restructures the block space into a distinct data field (blobspace) with its own fee market, enabling high data throughput for rollups without fragmenting the chain into independently executed shards.
In Simple Terms
Danksharding is a planned upgrade to Ethereum’s core architecture that reorganizes block space so large chunks of rollup data can be included and verified efficiently. It treats this data as a separate resource from normal transactions, allowing much more data to be published on-chain while keeping the main chain logically unified.
Context and Usage
Danksharding is discussed in the context of Ethereum scalability, data availability, and rollup ecosystems. It is referenced when describing how blobspace is structured, how rollups publish their data to the base layer, and how the protocol distinguishes between computation-focused gas fees and data-focused pricing. The term appears frequently in research on sharding, data-availability sampling, and long-term Ethereum roadmap milestones.
