EigenDA

aid: eigenda
name: EigenDA
description: >-
  EigenDA is a secure, high-throughput, decentralized data availability (DA)
  service built on top of Ethereum using EigenLayer restaking primitives.
  Developed by Eigen Labs and operated as the flagship product of EigenCloud,
  EigenDA accepts blobs of rollup data from rollup sequencers, erasure-codes
  them, distributes the chunks across a network of EigenLayer-restaked
  operators, and produces aggregate BLS signatures that anchor data
  availability on Ethereum L1. The service is positioned as a hyperscale DA
  layer for rollups, advertising 1 GB/s of design throughput and is secured
  by 4M+ ETH restaked through EigenLayer with validators that include
  Coinbase, Google, Nethermind, and Puffer. EigenDA is consumed today by
  rollups and chains including Celo, MegaETH, and Aevo, with integrations
  available for Arbitrum Orbit, OP Stack, Nitro, and the Sovereign SDK. The
  protocol exposes a gRPC API surface across a Disperser (blob ingest and
  status), Relays (blob and chunk retrieval), Retriever (reconstructive
  retrieval), Churner (operator registration), and Validator/Node endpoints.
  v2 of the protocol introduces a payment vault and the GetPaymentState RPC
  on the Disperser, replacing per-account static throughput reservations
  with a programmatic payments surface. The reference implementation is
  open source in Go (with a Rust client and SDKs in Rust and TypeScript),
  licensed Apache-2.0 / MIT, and developed in the open on GitHub.

    name: EigenDA Disperser API
    description: >-
      gRPC API exposed by the EigenDA Disperser. Rollups submit raw blobs
      to DisperseBlob, then poll GetBlobStatus until the blob is confirmed
      and dispersed across the operator set. v2 adds GetBlobCommitment,
      GetPaymentState (payment vault accounting), and
      GetValidatorSigningRate.

      gRPC service exposing GetBlob, GetChunks, and GetValidatorChunks
      against blobs stored by the relay layer. Relays sit between rollups
      and validators and front the read path for posted blobs.

    description: >-
      gRPC service that handles operator registration via the Churn RPC.
      The Churner decides whether new operators may join the EigenDA
      operator set and which existing operators are evicted when the
      registered stake exceeds protocol capacity.

    description: >-
      gRPC API served by EigenDA operator nodes. Validators receive chunk
      dispersals from the Disperser, sign aggregated attestations, and
      serve chunk retrieval. v2 introduces node_v2.proto and a separate
      signing_rate.proto for measuring per-validator availability.
