rapid snark is a zkSnark proof generation written in C++. That generates proofs created in circom and snarkjs very fast.
You should have installed gcc and cmake
In ubuntu:
sudo apt install build-essential
sudo apt install cmake
git submodule init
git submodule update
./build_gmp.sh host
mkdir build_prover && cd build_prover
cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../package
make -j4 && make installgit submodule init
git submodule update
./build_gmp.sh host_noasm
mkdir build_prover && cd build_prover
cmake .. -DTARGET_PLATFORM=arm64_host -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../package
make -j4 && make installgit submodule init
git submodule update
./build_gmp.sh host
mkdir build_prover && cd build_prover
cmake .. -DTARGET_PLATFORM=arm64_host -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../package
make -j4 && make installgit submodule init
git submodule update
./build_gmp.sh host
mkdir build_prover && cd build_prover
cmake .. -DTARGET_PLATFORM=aarch64 -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../package_aarch64
make -j4 && make installInstall Android NDK from https://developer.android.com/ndk or with help of "SDK Manager" in Android Studio.
Set the value of ANDROID_NDK environment variable to the absolute path of Android NDK root directory.
Examples:
export ANDROID_NDK=/home/test/Android/Sdk/ndk/23.1.7779620 # NDK is installed by "SDK Manager" in Android Studio.
export ANDROID_NDK=/home/test/android-ndk-r23b # NDK is installed as a stand-alone package.Compilation:
git submodule init
git submodule update
./build_gmp.sh android
mkdir build_prover_android && cd build_prover_android
cmake .. -DTARGET_PLATFORM=ANDROID -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../package_android
make -j4 && make installInstall Xcode.
git submodule init
git submodule update
./build_gmp.sh ios
mkdir build_prover_ios && cd build_prover_ios
cmake .. -GXcode -DTARGET_PLATFORM=IOS -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../package_iosOpen generated Xcode project and compile prover.
You might use the Dockerfile avialable on this repository for setting up the build environment and perform the compilation.
To create the docker image, execute:
docker image build -t rapidsnark .
The image compiles rapidsnark and libgpm for host x86_64.
You can create a new container and access to bash (source code available in /src directory).
docker run -it rapidsnark
Then you can extract the compiled files by executing the following docker command:
docker cp <container_id>:/src/package rapidsnark_package
You have a full prover compiled in the build directory.
So you can replace snarkjs command:
snarkjs groth16 prove <circuit.zkey> <witness.wtns> <proof.json> <public.json>by this one
./package/bin/prover <circuit.zkey> <witness.wtns> <proof.json> <public.json>This prover parallelizes as much as it can the proof generation.
The prover is much faster that snarkjs and faster than bellman.
[TODO] Some comparative tests should be done.
