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.

    the retrieved chunks via the RetrieveBlob RPC.

  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.

  name: EigenDA Validator Node API
  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.
