EIP-4844 (Proto-Danksharding)

Introduced with the Dencun upgrade, Proto-Danksharding (EIP-4844) significantly reduces transaction costs for Layer 2 rollups by introducing 'data blobs' for cheaper data availability, paving the way for further scalability.

The top 3

  1. Top 3 L2 Fees Reductions After EIP-4844: Following EIP-4844, transaction costs on major Layer 2 networks like Arbitrum, Optimism, and Base dropped by over 90% due to the introduction of 'blobs' for data storage.
  2. The Origin Story: Why 4844 Is Named 'Proto-Danksharding': Named after researcher Dankrad Feist, this proposal was designed as a necessary intermediate step to solve Ethereum's scalability bottleneck before full Danksharding is technically feasible. Dankrad Feist
  3. Blob Duration Record: The 18-Day Data Lifecycle: Unlike permanent calldata, EIP-4844 'blobs' are only stored on consensus nodes for approximately 18 days before they are pruned to keep node requirements manageable. EIP-4844 (Proto-Danksharding)
