Research on blockchain data availability, cryptographic commitments and protocol design. His writing separates publishing data from executing transactions, then shows how that distinction affects scaling.
Why read Dankrad Feist?
Start with Dankrad's short essay on what a blockchain does. Its example of Alice paying Bob separates two jobs: publishing an ordered transaction and interpreting it as a transfer. That distinction gives you a useful way to read scaling claims: faster execution still leaves the question of how other participants obtain and check the data.
His coauthored EIP-4844 takes the idea into a concrete design. It introduces blobs whose contents are separate from EVM execution, while contracts can access their commitments. Read the rollup rationale after the abstract to see why temporary data availability can be useful without storing everything forever. The essay is partly an outline; the specification is the technical next step.

What's the core functionality of blockchains
Begin with the Alice-to-Bob example and the distinction between data availability and execution. The essay then separates bugs in present rules from changes to future rules; its later sections remain outline notes.

EIP-4844: Shard Blob Transactions
A coauthored proposal, created on this date. Read the abstract and rollup rationale for why blobs have a separate fee market and their contents are not available to EVM execution.
