RISC Zero Rust Starter Template

(This repository has been deprecated in favor of the cargo risczero tool's new command.)

Welcome to the RISC Zero Rust Starter Template! This template is intended to give you a starting point for building a project using the RISC Zero zkVM. Throughout the code are comments labelled TODO in places where we expect projects will need to modify the code.

TODO: Replace this README with a README for your project TODO: Verify whether the included .gitignore, LICENSE, and rust-toolchain files are appropriate to your project

Quick Start

First, make sure rustup is installed. This project uses a nightly version of Rust. The rust-toolchain file will be used by cargo to automatically install the correct version.

To build all methods and execute the method within the zkVM, run the following command:

cargo run

This is an empty template, and so there is no expected output (until you modify the code).

How to create a project based on this template

Search this template for the string TODO, and make the necessary changes to implement the required feature described by the TODO comment. Some of these changes will be complex, and so we have a number of instructional resources to assist you in learning how to write your own code for the RISC Zero zkVM:

• The Getting Started section of the RISC Zero website is a great place to get started. There are additional explainers and overviews on our website as well.
• Example projects are available in our risc0/risc0-rust-examples repository.
• Reference documentation for our Rust crates is available at [docs.rs], including the RISC Zero zkVM crate, the RISC Zero zkVM guest crate, the RISC Zero build crate, and others (the full list is available at [https://github.com/risc0/risc0/blob/main/README.md]).
• Our main repository.

Stable Versions

By default, this template depends on the latest version of RISC Zero: the main branch of our main repository. This gives you access to our latest features and improvements. If you would prefer to use our more stable published crates, we have tags matching those crates that you can use, e.g. v0.11.1.

Contributor's Guide

We welcome contributions to documentation and code via PRs and GitHub Issues on our main repository, this repository, or any of our other repositories.
