Summary

This release is required for users and operators to upgrade.

We are excited to release EigenDA v0.9.0, code name "Blazar" (aka. EigenDA V2), a major protocol and architecture upgrade for the entire system.

Key Features and Enhancements

• Control Plane & Data Plane Separation
  Separates the flow of blob data from its metadata/control as they move through disperser, encoders and validators. This improves end-to-end data movement efficiency and boosts validator node performance and robustness by increasing network utilization through concurrent download connections.

• Payments Support
  EigenDA now supports on-demand payments and reservations, enabling applications to access the network permissionlessly with flexible payment options.

• Faster and Cheaper Dispersal with DA Certificate
  Reduces end-to-end dispersal latency and cost by eliminating on-chain confirmation and returning a DA certificate representing DA nodes' attestations.

• New Chunk Allocation Model
  Introduces a fixed-chunk model, making encoding a stateless operation and reducing system complexity.

• Revamped Blob State Management
  Enhances robustness by enforcing immutable records and introducing constraints into the data model.

• Improved Blob Addressing
  Introduces Blobkey, a universally unique string identifier for each blob, replacing the previous composite key (batch header hash + blob index). This simplifies interactions and improves UX when working with blobs.
