Danksharding is a method to scale the amount of data on the Ethereum chain in a future version of the platform using Data Availability Sampling (DAS).
- It follows protodanksharding (EIP-4844), which introduces a new transaction type called a "blob-carrying transaction."
- These data blobs will be dispersed among validators, and each validator will store only a small subset of data, ensuring that the whole block is sufficiently covered.
- Other projects, such as Celestia and EigenLayer, are also adopting DAS techniques to increase the available data space.
- A sampling protocol and a reconstruction protocol are used to recover the block.
- Polynomial commitments and erasure coding are building blocks of the scheme.
