BlobEncoder class abstract

Encodes raw blob data into Walrus slivers and computes metadata.

The Walrus protocol requires blobs to be erasure-coded before registration on-chain. The encoding produces:

  • A Merkle root hash over the encoded slivers
  • A blob ID derived from the root hash, encoding type, and size
  • Encoded slivers for distribution to storage nodes

Phase 2 usage

Since the concrete encoder is Phase 3, Phase 2 users have two options:

  1. Upload Relay path: Provide raw blob data to the relay, which handles encoding server-side. Pre-computed metadata must still be supplied for on-chain registration.

  2. Custom encoder: Implement this interface with your own encoding logic and pass it to WalrusDirectClient.

Current

WalrusBlobEncoder provides canonical RS2 encoding via Rust FFI, enabling fully client-side encoding without the upload relay.
