SP1 Wasm verification example

This repo demonstrates how to verify Groth16 and Plonk proofs in browser. We wrap the sp1-verifier crate in wasm bindings, and invoke it from javascript.

Repo overview

• verifier: The rust sp1 verifier crate with wasm bindings.
• example/fibonacci-program: A simple fibonacci SP1 program to verify.
• example/fibonacci-script: A simple script to generate proofs in a json format.
• example/wasm_example: A short javascript example that verifies proofs in wasm.

Usage

Wasm Bindings

First, generate the wasm library for the verifier. From the verifier directory, run

wasm-pack build --target nodejs --dev 

Generate proofs

Next, run the script to generate fibonacci_groth16_proof.json and fibonacci_plonk_proof.json. From the example/script directory, run:

cargo run --release -- --mode groth16
cargo run --release -- --mode plonk

By default, this will not generate fresh proofs from the program in example/fibonacci-program. To generate fresh proofs, run:

cargo run --release -- --mode groth16 --prove
cargo run --release -- --mode plonk --prove

Verify proofs in wasm

To verify proofs in wasm, run the following command from the example/wasm_example directory:

pnpm install
pnpm run test
