What are blobs?

Blobs (Binary Large Objects) are data structures introduced in Ethereum's EIP-4844 ("Proto-Danksharding") that provide cost-efficient storage for Layer 2 rollups, reducing fees compared to traditional calldata. These temporary structures attach to blocks without affecting Ethereum's state.

Key benefits:

  • Lower transaction costs for rollup users
  • Increased data throughput for Layer 2 solutions
  • Progress toward Ethereum's full sharding
  • Data availability without permanent state bloat

BlobFlow tracks blob usage, costs, and attribution across rollup providers in real time: fees, blocks, and mempool activity update live as each new block lands.
