RISC Zero Rust Starter Template
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 template (including in this README), you'll find comments
labelled TODO
in places where you'll need to make changes. To better
understand the concepts behind this template, check out the zkVM
Overview.
Quick Start
First, make sure rustup is installed. The
rust-toolchain.toml
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).
Executing the project locally in development mode
During development, faster iteration upon code changes can be achieved by leveraging dev-mode, we strongly suggest activating it during your early development phase. Furthermore, you might want to get insights into the execution statistics of your project, and this can be achieved by specifying the environment variable RUST_LOG="[executor]=info"
before running your project.
Put together, the command to run your project in development mode while getting execution statistics is:
RUST_LOG="[executor]=info" RISC0_DEV_MODE=1 cargo run
Running proofs remotely on Bonsai
Note: The Bonsai proving service is still in early Alpha; an API key is required for access. Click here to request access.
If you have access to the URL and API key to Bonsai you can run your proofs
remotely. To prove in Bonsai mode, invoke cargo run
with two additional
environment variables:
BONSAI_API_KEY="YOUR_API_KEY" BONSAI_API_URL="BONSAI_URL" cargo run
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 RISC Zero Developer Docs is a great place to get started.
- Example projects are available in the examples folder of
risc0
repository. - Reference documentation is available at https://docs.rs, including
risc0-zkvm
,cargo-risczero
,risc0-build
, and others.
Directory Structure
It is possible to organize the files for these components in various ways. However, in this starter template we use a standard directory structure for zkVM applications, which we think is a good starting point for your applications.
