arkworks::utils

The arkworks ecosystem consists of Rust libraries for designing and working with zero knowledge succinct non-interactive arguments (zkSNARKs). This repository contains ark-std, a library that serves as a compatibility layer for no_std use cases, and also contains useful methods and types used by the rest of the arkworks ecosystem.

This library is released under the MIT License and the Apache v2 License (see License).

WARNING: This is an academic proof-of-concept prototype, and in particular has not received careful code review. This implementation is NOT ready for production use.

Build guide

The library compiles on the stable toolchain of the Rust compiler. To install the latest version of Rust, first install rustup by following the instructions here, or via your platform's package manager. Once rustup is installed, install the Rust toolchain by invoking:

rustup install stable

After that, use cargo, the standard Rust build tool, to build the libraries:

git clone https://github.com/arkworks-rs/utils.git
cd utils
cargo build --release

Tests

This library comes with comprehensive unit and integration tests for each of the provided crates. Run the tests with:

cargo test --all

Benchmarks

To run the benchmarks, install the nightly Rust toolchain, via rustup install nightly, and then run the following command:

cargo +nightly bench
