0G Labs

0G DA (Data Availability) gRPC

gRPC surface for the 0G data-availability layer. The Disperser service accepts blobs asynchronously (DisperseBlob), exposes polling for processing state (GetBlobStatus) and retrieval of a previously dispersed blob (RetrieveBlob); the Retriever service reads blobs back from the DA nodes; and the node-side Signer service handles BatchSign, BatchRetrieve and GetStatus. Rollups settle against this layer — OP Stack, Arbitrum Nitro, EigenLayer AVS and Babylon AVS integrations are all documented.

  (DisperseBlob), exposes polling for processing state (GetBlobStatus) and retrieval of a previously dispersed
  blob (RetrieveBlob); the Retriever service reads blobs back from the DA nodes; and the node-side Signer

x-deployment: self-hosted
x-baseurl-note: 0G hosts no public DA endpoint — a DA Client, Encoder and Retriever are run by the integrator
  (the docs default the client server to 127.0.0.1:51001, and the container publishes port 51001). No
  baseURL is recorded rather than pointing one at a docs page or a localhost address; the contract here
  is the protobuf, not a vendor-operated endpoint.
