  "id": 7594,
  "title": "EIP-7594: PeerDAS - Peer Data Availability Sampling",
  "status": "Final",
  "type": "Standards Track",
  "category": "Core",
  "summary": "PeerDAS enables Ethereum nodes to specialize in storing different pieces of data while still verifying everything is available. This foundational change dramatically increases data capacity for Layer 2 networks while maintaining security.",
  "impacts": [
    "Benefits through much cheaper Layer 2 transactions and access to applications that need more data throughput.",
    "Enables building applications with higher data requirements. Layer 2 developers benefit from reduced costs and higher capacity limits.",
    "Minimal direct impact. Users benefit indirectly through better Layer 2 transaction reliability and lower costs.",
    "Major updates needed for block explorers, indexers, and data availability APIs to handle the new sampling system and proof formats.",
    "Game-changing for Layer 2 economics - dramatically reduces costs for posting transaction data and enables much higher throughput rollups.",
    "Must implement the new specialized data storage and sampling system. Changes from downloading everything to participating in a coordinated verification network.",
    "Major implementation work required for the new data distribution system, sampling protocols, and coordination between nodes. This is a core infrastructure change.",
    "Need to update how blob transactions are handled and verified, including new proof formats and validation methods.",
    "Dramatically reduces Layer 2 transaction costs",
    "Enables scaling to 128+ blobs per block over time",
    "Nodes only store a fraction of data while maintaining security",
    "Foundation for competing with high-speed blockchains",
    "Paves the way for full Danksharding"
