Just Starting Out
If you're new to the RISC Zero zkVM, these examples and explanations will get you oriented. Below is a tutorial that'll help you build our version of "Hello, World!" and an introduction to the default RISC Zero project template.
Hello, Multiply! - Think of this as "Hello, World!" for the RISC Zero zkVM. By following this tutorial, you'll create a program that demonstrates a number is composite (and that you know its factors). If you're just getting started writing code for the zkVM, we recommend starting here.
Understanding the Project Template - Here we'll take a closer look at the template we provide for starting your own RISC Zero zkVM project. You'll understand which parts are necessary and which can be changed, and get a feel for how the project components work together. (And if you like understanding the structure of a project before diving in, feel free to start here instead!)
For more ideas about what's possible with RISC Zero, take a look at our Rust examples repository. We also provide detailed explanations for the factors example (in Hello, Multiply above) and for the password-checker example:
- RISC Zero Password Validity Checker -
In this example, you'll see Alice convince Bob's Identity Service that her password meets Bob's validity requirements.
This example makes use of public shared outputs that Alice can write to the RISC Zero zkVM's
We presented a workshop teaching the RISC Zero zkVM at ZK Hack III. You can view the full presentation on Youtube, or watch individual segments from our playlist, including examples for
Reference documentation for our Rust code is available on docs.rs. This includes documentation for our primary zkVM crate, risc0-zkvm, which includes tools for host-guest communication, proving, and receipt verification. The full list of our crates, including links to their documentation, is available here.
Our source code is available on GitHub. Our main repository is risc0. We provide a Rust starter template repository to help people start their own projects using the RISC Zero zkVM, and have a variety of examples in our Rust examples repository.
We also have packaged Rust crates available, listed here.
