MALT v0.0.7-rc.4 reduces Writer latency for transactions that change multiple Map arcs by computing one final top-level commitment.

Highlights

  • The graph Writer sends canonical changes for one Map object through one semantic BatchUpdate.
  • The radix Map opens and validates the existing top-level node once, applies subtree changes in batch-local state, and persists one final top-level commitment.
  • Ordered changes below the same root slot are preserved.
  • Batched final roots are byte-for-byte identical to sequential updates.

Compatibility

This is an execution optimization, not an aggregated proof or a portable transition-proof contract. It does not alter MALT roots, CIDs, commitment parameters, commitments, proofs, transcripts, ProofLists, receipts, schemas, or wire encodings.

The v0.0.7 release-candidate line remains pre-v1 and wire-incompatible with the flat v0.0.6 root codecs. See the source release notes for the full rc.1 through rc.4 compatibility contract.
