v0.0.1 — Initial Public Release

What is MALT

MALT is an authenticated mutable structure layer over immutable content-addressed storage. It introduces Explicit Arcs — verifiable bindings independent of immutable object content — with map and list semantic primitives for unified path traversal and range verification.

⚠️ Research prototype. This is an early release for the paper submission. APIs, storage formats, and proof schemas may change without notice until a stable version is tagged.

Highlights

• Root-centric verification: Read(root, query) → result + ProofList — clients verify correctness against the root, not the server
• Semantic mutation: ApplyMutation(baseRoot, delta) → newRoot + writeReceipt
• UnixFS compatibility: add, resolve, and verify files/directories over the MALT structure layer
• Local daemon: single-binary malt daemon with HTTP API on 127.0.0.1:4317
• Evaluation CLI: malt-eval for benchmarking read latency, write amplification, and proof overhead across MALT-flat, IPLD UnixFS, and HAMT baselines

Quick Start

# Requires Go 1.25.7+

Known Limitations

- ProofList step schema is intentionally deferred (see MIP-1003)
- KZG commitment backend uses looped encoding pending upstream batch proof support
- No release workflow yet — this is a source-only tag
