Rs Merkle

Rs Merkle is a Rust library for building configurable Merkle trees, creating and verifying single-element and multi-element proofs, and applying transactional tree changes with rollback to committed states.

Practical overview

When it fits

Use Rs Merkle when a Rust application needs configurable hash-tree construction, Merkle inclusion proofs, multi-proofs, or rollback-capable tree updates. It can support blockchain-related verification tasks, such as checking transaction inclusion, but is a library rather than a complete blockchain application.

Who it is for

  • Rust developers adding Merkle-tree functionality to an application.
  • Teams that need to verify data membership or compare datasets using proofs rather than exchanging the complete collection.
  • Developers building projects that require a no-std dependency configuration.

Documented uses

  • Build a Merkle tree from application data.
  • Create and verify a proof for one element or several elements.
  • Configure the tree's hashing function and construction method.
  • Make transactional tree changes and roll back to a previously committed state.
Before you choose

Requirements & limits

The project is open source under the MIT License. Its README lists the crate on crates.io and API documentation on docs.rs.

  • The library is written in Rust and is added through Cargo.
  • Hashing and tree construction are configurable through a trait.
  • Single-element proofs and multi-proofs are supported.
  • The README documents disabling default features for no-std projects.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Add Rs Merkle as a Rust dependency

Configure a Rust project to use the library, including its documented no-std option.

Before you start

  • A Rust project using Cargo.

Steps

  1. Add rs_merkle = "1.4" to the project's Cargo.toml dependencies.

  2. For a project requiring no-std, instead add rs_merkle = { version = "1.4", default-features = false }.

Expected outcome

The Cargo manifest declares Rs Merkle as a project dependency, with default features disabled for the documented no-std configuration.

Guide limitations

  • These steps configure the dependency; they do not demonstrate building a tree or creating or verifying a proof.
