# Hyphae

> Hyphae is a local-first data engine written in Rust. One process owns one data directory and exposes relational SQL, native keyspace structures, lexical (BM25/BM25F) search and vector search over one shared transaction log, MVCC snapshot space and commit sequence. Results can carry proofs a third party verifies offline. Release 3.0.0 (2026-09-04) is published on crates.io as 24 crates.

Wording authority: every capability statement follows https://github.com/Hyphae-Research-Foundation/hyphae/blob/main/docs/product/claims.md. Comparisons are "Valkey-shaped", never "Redis-compatible". Performance numbers are receipts bound to a commit and a host class; they are not general claims.
