GO VDF

Running Verifiable Delay Function in GO

Compile Chia VDF

1. Clone ChiaVDF official repostory. To do so, we can run:

git submodule update --init

2. Install compiling tools.

sudo apt-get install cmake libgmp-dev libboost-system-dev build-essential -y

3. Edit chiavdf/src/CMakeLists.txt, by turning on the chiavdfc option, and turning off the python option.

option(BUILD_CHIAVDFC "Build the chiavdfc shared library" ON)
option(BUILD_PYTHON "Build the python bindings for chiavdf" OFF)

4. Create directory chiavdf/build. Then move into it.

mkdir chiavdf/build
cd chiavdf/build

5. Run CMake to configure the project. Pass as parameter the directory in which CMakeLists.txt is located.

cmake ../src

6. Build the project.

make

By following these commands, we obtain a compiled C VDF library: libchiavdfc.a, located inside chiavdf/build/static.

RUN GO FILE

1. Export absolute path of C Wrappers for ChiaVDF.

export CGO_CFLAGS="-I/path/to/chiavdf/src/c_bindings"

2. Export absolute path ob libchiavdfc and libgmp.

export CGO_LDFLAGS="-L/path/to/chiavdf/build/lib/static -L/usr/lib/x86_64-linux-gnu -lgmp"

3. (⚠️ Not working) Run main program.

go run main.go
