## Overview

TraverseV is a Rust library for memory-hard proof-of-work. A caller configures parameters and constructs a trustless or permissioned instance; construction derives and fills a memory buffer. Mining searches nonce candidates using a sequential, read-only traversal and returns a proof meeting the configured difficulty; verification checks a supplied candidate without repeating the search. The graph includes block/mixing primitives as the internal implementation layer. Some evaluation details are described only in the README, so those links cite it rather than implying the unsampled implementation was inspected.

Main entry points: [`src/lib.rs`](https://github.com/0x44-labs/rs-traversev/blob/main/src/lib.rs) (TraverseV API), [`src/memory/fill.rs`](https://github.com/0x44-labs/rs-traversev/blob/main/src/memory/fill.rs) (Multi-pass fill), [`src/params.rs`](https://github.com/0x44-labs/rs-traversev/blob/main/src/params.rs) (Parameters), [`src/block.rs`](https://github.com/0x44-labs/rs-traversev/blob/main/src/block.rs) (Memory block)
