mopro-core

Core mobile Rust library. For FFI, see mopro-ffi which is a thin wrapper for exposing UniFFI bindings around this library.

Overview

TBD.

Examples

Run cargo run --example circom. Also see examples/circom/README.md for more information.

Build dylib

Experimental support.

Turns .wasm file into a dynamic library (.dylib).

Run:

cargo build --features dylib

After that you'll see location of the dylib file:

warning: Building dylib for aarch64-apple-darwin
warning: Dylib location: /Users/user/repos/github.com/zkmopro/mopro/mopro-core/target/debug/aarch64-apple-darwin/keccak256.dylib

Right now this is hardcoded for rsa.

Note that:

  • It has to be built for the right architecture
  • Have to run install_name_tool to adjust install name
  • Run codesign to sign dylib for use on iOS

Script

  • Add third argument dylib
  • Add forth argument with name of dylib, e.g. rsa if you want rsa.dylib

./scripts/update_bindings.sh device release dylib rsa

Note that APPLE_SIGNING_IDENTITY must be set.

To use ark-zkey

Experimental support for significantly faster zkey loading. See ../ark-zkey README for how to build arkzkey.

To run msm benchmark report on laptop

cargo run --release --features gpu-benchmarks --package mopro-core --bin generate_benchmark_report

The report will be in mopro-core/benchmarks/gpu_explorations/msm_bench_rust_laptop.csv.

To use circom-witness-rs (Experimental)

  • Set
    [witness]
    use_native_witness_generation = true
    in config.toml file
  • Or build witness with
    WITNESS_CPP=<CIRCOM_PATH> cargo build --features build-native-witness --release
    Test with
    cargo test --features calc-native-witness
