mopro

Making client-side proving on mobile simple.

Overview

This is a WIP.

• mopro-core - core mobile Rust library.
• mopro-ffi - wraps mopro-core and exposes UniFFI bindings.
• mopro-ios - iOS CocoaPod library exposing native Swift bindings.
• mopro-example-app - example iOS app using mopro-ios.

Architecture

The following illustration shows how mopro and its components fit together into the wider ZKP ecosystem:

Zooming in a bit:

Prepare

• Install circom and snarkjs
• Install cocoapods
• Run ./scripts/prepare.sh to check all prerequisites are set.

Build Bindings

To build bindings for iOS simulator debug mode, run

./scripts/build_ios.sh simulator debug

Open the mopro-ios/MoproKit/Example/MoproKit.xcworkspace in Xcode.

Bindings

To update bindings, run ./scripts/update_bindings.sh simulator|device debug|release.

• simulator is for building library to run on iOS simulator, device is for running on a real device
• debug is for Rust library to be in debug mode and release for release mode
