Rollup Data Availability

Utilizing NEAR as storage data availability with a focus on lowering rollup DA fees.

  • Blob Store Contract: A contract that provides the store for arbitrary DA blobs.
  • Light Client: A trustless off-chain light client for NEAR with DA-enabled features.
  • RPC Client: The defacto client for submitting data blobs to NEAR.
  • Integrations: Proof of concept works for integrating with L2 rollups.
tip

For the latest information, please check the Near DA repository.

System Context​

This outlines the system components that we build and how it interacts with external components.

Red lines denote external flow of commitments. White lines denote flow of blob data.

Note: "fisherman" is just an example how a rollup can work with the light client in the initial stage of DA, until we implement a more non-interactive approach, such as KZG.
