Practical Applications
Getting Started with the zkVM
Using the Nexus SDK, proving Rust programs is straightforward:
- Installation: Follow the Nexus documentation for setup.
Project Structure:
$ cargo nexus host nexus-hostCreates:
./nexus-host ├── Host program (main.rs) └── Guest program (guest/src/main.rs)
Example Workflow
Guest Program (simple multiplication):
#![cfg_attr(target_arch = "riscv32", no_std, no_main)]
use nexus_rt::println;
#[nexus_rt::main]
#[nexus_rt::public_input(x)]
fn main(x: u32, y: u32) -> u32 {
println!("Read public input: {}", x);
println!("Read private input: {}", y);
x * y
}Host Program (execution and verification):
use nexus_sdk::{compile, Prover, Verifiable};
fn main() {
// Compile and prove guest program
let (view, proof) = prover.prove_with_input::<u32>(&3, &5).unwrap();
assert_eq!(view.public_output::<u32>().unwrap(), 15);
proof.verify_expected(&5, 0, &15, &elf, &[]).unwrap();
