Verkle Cryptography (WASM/TypeScript)

Note: This library is in the process of moving over from https://github.com/crate-crypto/rust-verkle-wasm. Package and build structure are in the process of being reworked and documentation/instructions are not yet fully updated.

This library provides a WASM build bundled with a TypeScript API of the Rust rust-verkle implementation and exposes core Verkle Tree related crypto and arithmetic primitives to be consumed and used by higher level packages.

The library has been initially developed by kevaundray (a thousand ❤️s for all the great work!) and is now maintained and further developed by Kev and the Ethereum Foundation JavaScript team.

A higher level Verkle Tree TypeScript library using this package is in the works at https://github.com/ethereumjs/ethereumjs-monorepo/tree/master/packages/verkle.

Installation

    npm i verkle-cryptography-wasm

Basic Structure

Rust/WASM

The Rust code and the necessary tooling for the WASM build and a low level TypeScript API exposure can be found in ./src.rs. The associated README contains the main documentation describing the WASM build process.

High Level TypeScript API

The main high level API exposed in a final published package can be found in ./src.ts. Usage instructions can be found here

Node.js

The root folder of this package holds a Node.js package.json file referencing the final package exports and the necessary build scripts.

Build

Build scripts can be found in the scripts folder and the build process can be triggered with:

npm run build

See the comments in the build scripts for a more detailed explanation of what occurs in each step.

Note that this requires all Rust/WASM tooling to be installed, so a first look into the dedicated RUST/WASM documentation is recommended.

Testing

There are a few high level JavaScript API respectively unit tests available which can be run with:

npm run test
